自定义iOS 中推送消息 提示框

看到标题你可能会觉得奇怪 推送消息提示框不是系统自己弹出来的吗？ 为什么还要自己自定义呢？

因为项目需求是这样的：最近需要做 远程推送通知 和一个客服系统 包括店铺客服和官方客服两个模块 如果有新的消息推送的时候 如果用户当前不在客服界面的时候  要求无论是在app前台 还是app退到后台 顶部都要弹出系统的那种消息提示框

这样的需求 我们就只能自定义一个在app内 弹出消息提示框 

实现步骤如下：

1.我们自定义一个view 为 STPushView 推送消息的提示框view

#import <UIKit/UIKit.h>
#import "STPushModel.h"

@interface STPushView : UIView

/** *推送数据模型 */
@property(nonatomic,strong) STPushModel *model;

+(instancetype)shareInstance;
+ (void)show;
+ (void)hide;

@end

#import "STPushView.h"
#import "AppDelegate.h"

@interface STPushView()

@property (nonatomic, weak) UIImageView *imageV;
@property (nonatomic,weak ) UILabel  *timLabel;
@property (nonatomic,weak ) UILabel  *content;

@end

@implementation STPushView

static STPushView *_instance = nil;

+(instancetype)shareInstance
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _instance = [[STPushView alloc] init];
    });
    return _instance;
}

+(instancetype) allocWithZone:(struct _NSZone *)zone
{
    if (!_instance) {
        _instance = [super allocWithZone:zone];
    }
    return _instance ;
}

- (instancetype)initWithFrame:(CGRect)frame
{
    if (self = [super initWithFrame:frame]) {
        
        self.backgroundColor = CUSTOMCOLOR(15, 14, 12);
        
        CGFloat margin = 12;
        UIImageView *imageV = [[UIImageView alloc] init];
        imageV.userInteractionEnabled = NO;
        imageV.image = [UIImage imageNamed:@"logo"];
        imageV.layer.cornerRadius = 5;
        [self addSubview:imageV];
        self.imageV = imageV;
        [imageV mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.equalTo(self).offset(margin);
            make.centerY.equalTo(self.mas_centerY);
            make.width.mas_equalTo(30);
            make.height.mas_equalTo(30);
        }];
        
        
        UILabel *titleLabel = [[UILabel alloc] init];
        titleLabel.textColor = [UIColor whiteColor];
        titleLabel.font = [UIFont boldSystemFontOfSize:12];
        titleLabel.text = @"121店官方客服";
        [self addSubview:titleLabel];
        [titleLabel mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.equalTo(imageV.mas_right).offset(margin);
            make.top.equalTo(self.mas_top).offset(margin);
            make.height.mas_equalTo(16);
        }];
        [titleLabel sizeToFit];
        
        UILabel *timLabel = [[UILabel alloc] init];
        timLabel.font = [UIFont systemFontOfSize:12];
        timLabel.userInteractionEnabled = NO;
        timLabel.textColor = [UIColor whiteColor];
        timLabel.text = @"刚刚";
        timLabel.textColor = [UIColor lightGrayColor];
        [self addSubview:timLabel];
        self.timLabel = timLabel;
        [timLabel mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.equalTo(titleLabel.mas_right).offset(margin);
            make.top.equalTo(self.mas_top).offset(margin);
            make.width.mas_lessThanOrEqualTo(40);
            make.height.mas_equalTo(16);
        }];
        
        
        UILabel *content = [[UILabel alloc] init];
        content.numberOfLines = 2;
        content.font = [UIFont systemFontOfSize:13];
        content.textColor = [UIColor whiteColor];
        content.userInteractionEnabled = NO;
        [self addSubview:content];
        self.content = content;
        [content mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.equalTo(imageV.mas_right).offset(margin);
            make.top.equalTo(titleLabel.mas_bottom).offset(-3);
            make.right.equalTo(self.mas_right).offset(-margin);
            make.height.mas_equalTo(35);
        }];
        
        
        UIView *toolbar = [[UIView alloc] init];
        toolbar.backgroundColor = CUSTOMCOLOR(121, 101, 81);
        toolbar.layer.cornerRadius = 3;
        [self addSubview:toolbar];
        [toolbar mas_makeConstraints:^(MASConstraintMaker *make) {
            make.width.mas_equalTo(35);
            make.height.mas_equalTo(6);
            make.centerX.equalTo(self.mas_centerX);
            make.bottom.equalTo(self.mas_bottom).offset(-2);
        }];
        
    }
    return self;
}

- (void)setModel:(STPushModel *)model
{
    _model = model;
    self.timLabel.text = @"刚刚";
    self.content.text = model.content;
}

+ (void)show
{
    
    [UIApplication sharedApplication].statusBarHidden = YES;
    STPushView *pushView = [STPushView shareInstance];
    pushView.hidden = NO;
    
    AppDelegate *app = (AppDelegate*)[UIApplication sharedApplication].delegate;
    [app.window bringSubviewToFront:pushView];

    [UIView animateWithDuration:0.25 animations:^{
        
        pushView.frame = CGRectMake(0, 0, SCREEN_WIDTH, pushViewHeight);
        
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            
            [UIView animateWithDuration:0.25 animations:^{
                
                pushView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight);
                
                
            } completion:^(BOOL finished) {
                
                [UIApplication sharedApplication].statusBarHidden = NO;
                pushView.hidden = YES;
                
            }];
            
        });
        
    }];
}

+ (void)hide
{
    STPushView *pushView = [STPushView shareInstance];

    [UIView animateWithDuration:0.25 animations:^{
        
        pushView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight);
        
    } completion:^(BOOL finished) {
        
        [UIApplication sharedApplication].statusBarHidden = NO;
        pushView.hidden = YES;
        
    }];

}

@end

上面pushView需要一个模型 实现代码如下

// push 推送的model

推送过来的数据如下：
/**
 content = dsfdsnfds;
 id = 5077;
 mid = 1270339;
 title = dsfdsnfds;
 url = "3?_from=push";
 urlType = 3;
 
 **/
#import <Foundation/Foundation.h>

@interface STPushModel : STBaseModel<NSCoding>  //STBaseModel 是一个继承自NSObject的类 我主要是在这个类中实现了字典转模型的功能 你可以直接修改为NSObject

/***id**/
@property (copy,nonatomic) NSString* recordId;
/***标题**/
@property (copy, nonatomic) NSString *title;
/***url**/
@property (copy, nonatomic) NSString *url;
/***url 类型**/
@property (copy, nonatomic) NSString* urlType;
/***图标的高度**/
@property (assign,nonatomic) NSString * mid;
/***推送内容**/
@property (copy, nonatomic) NSString* content;

@end

因为涉及到好几个页面需要使用同样的推送消息数据 进行判断而处理相应的业务 所有我对此模型做了归档处理

#import "STPushModel.h"

@implementation STPushModel


/**
 *  保存对象到文件中
 *
 *  @param aCoder <#aCoder description#>
 */
-(void)encodeWithCoder:(NSCoder *)aCoder
{
    [aCoder encodeObject:self.recordId forKey:@"recordId"];
    [aCoder encodeObject:self.title forKey:@"title"];
    [aCoder encodeObject:self.url forKey:@"url"];
    [aCoder encodeObject:self.urlType forKey:@"urlType"];
    [aCoder encodeObject:self.mid forKey:@"mid"];
    [aCoder encodeObject:self.content forKey:@"content"];
}


/**
 *  从文件中读取对象
 *
 *  @param aDecoder <#aDecoder description#>
 *
 *  @return <#return value description#>
 */
-(id)initWithCoder:(NSCoder *)aDecoder
{
    //注意：在构造方法中需要先初始化父类的方法
    if (self=[super init]) {
        self.recordId=[aDecoder decodeObjectForKey:@"recordId"];
        self.title=[aDecoder decodeObjectForKey:@"title"];
        self.url=[aDecoder decodeObjectForKey:@"url"];
        self.urlType=[aDecoder decodeObjectForKey:@"urlType"];
        self.mid=[aDecoder decodeObjectForKey:@"mid"];
        self.content= [aDecoder decodeObjectForKey:@"content"];
    }
    return self;
}
@end

做好了上面的准备工作之后  接下来我们就需要 APPdelegate里面注册远程推送通知  并且监听推送消息

这里以个推为例子：

第一步在下面的方法中 实现个推的注册方法

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  // 注册个推推送服务
    [[GeTuiApilmpl sharedInstance] geTuiRegister];


}

GeTuiApilmpl 是一个单例类 专门用于注册个推的推送方法  实现代码如下：

#import <Foundation/Foundation.h>
#import "GeTuiSdk.h"
@interface GeTuiApilmpl : NSObject <GeTuiSdkDelegate>

+ (GeTuiApilmpl *) sharedInstance;

- (void) geTuiRegister;

@end

#import "GeTuiApilmpl.h"

@implementation GeTuiApilmpl

+ (GeTuiApilmpl *) sharedInstance{
    static id instance = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        instance = [[self alloc] init];
    });
    return instance;
}

#pragma mark - GeTuiSdkDelegate
/** SDK启动成功返回cid */
- (void)GeTuiSdkDidRegisterClient:(NSString *)clientId {
    // [4-EXT-1]: 个推SDK已注册，返回clientId
    NSLog(@"
>>>[GeTuiSdk RegisterClient]:%@

", clientId);
}

/** SDK遇到错误回调 */
- (void)GeTuiSdkDidOccurError:(NSError *)error {
    // [EXT]:个推错误报告，集成步骤发生的任何错误都在这里通知，如果集成后，无法正常收到消息，查看这里的通知。
    NSLog(@"
>>>[GexinSdk error]:%@

", [error localizedDescription]);
}

/** SDK收到透传消息回调 */
- (void)GeTuiSdkDidReceivePayload:(NSString *)payloadId andTaskId:(NSString *)taskId andMessageId:(NSString *)aMsgId andOffLine:(BOOL)offLine fromApplication:(NSString *)appId {
    // [4]: 收到个推消息
    NSData *payload = [GeTuiSdk retrivePayloadById:payloadId];
    NSString *payloadMsg = nil;
    if (payload) {
        payloadMsg = [[NSString alloc] initWithBytes:payload.bytes length:payload.length encoding:NSUTF8StringEncoding];
    }
    NSString *msg = [NSString stringWithFormat:@" payloadId=%@,taskId=%@,messageId:%@,payloadMsg:%@%@", payloadId, taskId, aMsgId, payloadMsg, offLine ? @"<离线消息>" : @""];
    NSLog(@"
>>>[GexinSdk ReceivePayload]:%@

", msg);
    /**
     *汇报个推自定义事件
     *actionId：用户自定义的actionid，int类型，取值90001-90999。
     *taskId：下发任务的任务ID。
     *msgId： 下发任务的消息ID。
     *返回值：BOOL，YES表示该命令已经提交，NO表示该命令未提交成功。注：该结果不代表服务器收到该条命令
     **/
    [GeTuiSdk sendFeedbackMessage:90001 taskId:taskId msgId:aMsgId];
}

/** SDK收到sendMessage消息回调 */
- (void)GeTuiSdkDidSendMessage:(NSString *)messageId result:(int)result {
    // [4-EXT]:发送上行消息结果反馈
    NSString *msg = [NSString stringWithFormat:@"sendmessage=%@,result=%d", messageId, result];
    NSLog(@"
>>>[GexinSdk DidSendMessage]:%@

", msg);
}

/** SDK运行状态通知 */
- (void)GeTuiSDkDidNotifySdkState:(SdkStatus)aStatus {
    // [EXT]:通知SDK运行状态
    NSLog(@"
>>>[GexinSdk SdkState]:%u

", aStatus);
}

/** SDK设置推送模式回调 */
- (void)GeTuiSdkDidSetPushMode:(BOOL)isModeOff error:(NSError *)error {
    if (error) {
        NSLog(@"
>>>[GexinSdk SetModeOff Error]:%@

", [error localizedDescription]);
        return;
    }
    NSLog(@"
>>>[GexinSdk SetModeOff]:%@

", isModeOff ? @"开启" : @"关闭");
}

-(void)geTuiRegister{
    

  NSString *path = [[NSBundle mainBundle] pathForResource:@"libGexin" ofType:@"plist"];
        NSDictionary *dic = [NSDictionary dictionaryWithContentsOfFile:path];
  [GeTuiSdk startSdkWithAppId:[dic objectForKey:@"GT_APPID"]
                             appKey:[dic objectForKey:@"GT_APPKEY"]
                          appSecret:[dic objectForKey:@"GT_APPSECRET"]
                           delegate:self];

}

上面的 libGexin.plist 的配置内容如下：

然后再appDelegate 调用注册远程推送的方法 

/** 注册用户通知 */
- (void)registerUserNotification {
    /*
     注册通知(推送)
     申请App需要接受来自服务商提供推送消息
     */
    // 判读系统版本是否是“iOS 8.0”以上
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 ||
        [UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]) {
        // 定义用户通知类型(Remote.远程 - Badge.标记 Alert.提示 Sound.声音)
        UIUserNotificationType types = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;
        // 定义用户通知设置
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
        // 注册用户通知 - 根据用户通知设置
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    } else { // iOS8.0 以前远程推送设置方式
        // 定义远程通知类型(Remote.远程 - Badge.标记 Alert.提示 Sound.声音)
        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        // 注册远程通知 -根据远程通知类型
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
    }
}

然后在AppDelegate的 didFinishLaunchingWithOptions 写上如下代码：

调用：addPushView方法 添加 消息提示框STPushView:  addPushView实现代码如下

#pragma mark 推送信息展示
//添加推送view
- (void)addPushView
{
    STPushView *topView = [STPushView shareInstance];
    topView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight);
    [_window addSubview:topView];
    self.topView = topView;
    topView.hidden = YES;
    
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hudClick)];
    UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(pan:)];
    [topView addGestureRecognizer:tap];
    [tap requireGestureRecognizerToFail:pan];
    topView.gestureRecognizers = @[tap,pan];
    
}

#pragma mark  addPushView相关事件
- (void)hudClick
{
    self.topView.userInteractionEnabled = NO;
    
    [UIView animateWithDuration:0.25 animations:^{
        self.topView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight);
    }completion:^(BOOL finished) {
        [UIApplication sharedApplication].statusBarHidden = NO;
        [self hudClickOperation];
        
    }];
}

- (void)hudClickOperation
{
    [self push:nil];
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        self.topView.userInteractionEnabled = YES;
    });
}


- (void)pan:(UIPanGestureRecognizer*)pan
{
    CGFloat distance = pushViewHeight-(pushViewHeight-[pan translationInView:self.window].y);
    if (distance<-20) {
        [UIView animateWithDuration:0.25 animations:^{
            self.topView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight);
        }completion:^(BOOL finished) {
            [UIApplication sharedApplication].statusBarHidden = NO;
        }];
    }
}

//显示pushView
- (void)displayPushView
{
    [STPushView show];
}

上面push方法的实现代码如下： 处理逻辑 是根据我自己的项目中需求定的 在这里实现你需要处理的代码

- (void)push:(NSDictionary *)params{
    
    STPushModel *model = [ NSKeyedUnarchiver unarchiveObjectWithFile:KRAPI_PUSH_DATA];
    
    //如果是h5
    if ([model.urlType isEqualToString:@"h5"]) {
        
        BOOL isStore = [[AnalysisUrl sharedInstance] analysisWebUrl:model.url];
        BOOL isGoods = [[AnalysisUrl sharedInstance] analysisGoodsIdWebUrl:model.url];
        BOOL isRedBag =[[AnalysisUrl sharedInstance] analyredBagWebUrl:model.url];
        BOOL istrace =[[AnalysisUrl sharedInstance] analytraceWebUr:model.url];
        BOOL islog =[[AnalysisUrl sharedInstance] analylogWebUrl:model.url];
        if (isStore || isGoods) {
            [[WYPageManager sharedInstance] pushViewControllerWithUrlString:model.url currentUrlString:TRAKER_URL_INDEX];
            
        }else if (isRedBag)
        {
            RedBageViewController * regBag =[[RedBageViewController alloc]init];
            NSArray *array = [model.url componentsSeparatedByString:@"="];
            NSString * string = [array lastObject];
            regBag.messageID = string;
            regBag.redType = @"coupon";
            UITabBarController *tabVC = (UITabBarController *)self.window.rootViewController;
            UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex];
            // 跳转到对应的控制器
            regBag.hidesBottomBarWhenPushed = YES;
            [pushClassStance pushViewController:regBag animated:YES];
            return;
        }else if (istrace)
        {
            RedBageViewController * regBag =[[RedBageViewController alloc]init];
            NSString * string = [StrUtils getIdFromURLString:model.url interceptString:@"/trace/"];
            regBag.messageID = string;

                    UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex];
                    [pushClassStance pushViewController:messageVC animated:YES];
                }
            }else if ([model.url hasPrefix:@"http://"]&&([model.url rangeOfString:@"client"].location!=NSNotFound)){ //跳转到客服接 界面
                
                NSString *orgIdString =[[AnalysisUrl sharedInstance] extractOrgId:model.url];
                NSString *siteIdString = [[AnalysisUrl sharedInstance] extractOrgIdStoreId:model.url];
                [[WYPageManager sharedInstance] pushViewController:@"TLChatViewController" withParam:
                 @{
                   @"title_nameString":@"官方客服",
                   @"orgIdString":orgIdString,
                   @"siteIdString":siteIdString,
                   @"currentURL":model.url
                   } animated:YES];
                
            }
        }
}

然后再AppDelegate 实现以下方法

/** 自定义：APP被“推送”启动时处理推送消息处理（APP 未启动--》启动）*/
- (void)receiveNotificationByLaunchingOptions:(NSDictionary *)launchOptions {
    if (!launchOptions)
        return;
    /*
     通过“远程推送”启动APP
     UIApplicationLaunchOptionsRemoteNotificationKey 远程推送Key
     */
    NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (userInfo) {
        NSLog(@"
>>>[Launching RemoteNotification]:%@", userInfo);
    }
}

#pragma mark - 用户通知(推送)回调 _IOS 8.0以上使用

/** 已登记用户通知 */
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    // 注册远程通知（推送）
    [application registerForRemoteNotifications];
}

#pragma mark - 远程通知(推送)回调

/** 远程通知注册成功委托 */
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSString *myToken = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    myToken = [myToken stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSUserDefaults *kr = [NSUserDefaults standardUserDefaults];
    [kr setValue:myToken forKey:@"deviceToken"];
    [kr synchronize];
    [GeTuiSdk registerDeviceToken:myToken];
    [[PostDeviceToken sharedInstance] postUpDeviceToken];
    NSLog(@"
>>>[DeviceToken Success]:%@

", myToken);
}

/** 远程通知注册失败委托 */
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    [GeTuiSdk registerDeviceToken:@""];
    NSLog(@"
>>>[DeviceToken Error]:%@

", error.description);
}


#pragma mark - APP运行中接收到通知(推送)处理
/** APP已经接收到“远程”通知(推送) - 透传推送消息  */
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler {
    // 处理APN
    NSLog(@"
>>>[Receive RemoteNotification - Background Fetch]:%@

", userInfo);
    completionHandler(UIBackgroundFetchResultNewData);
  //    NSUserDefaults *kr = [NSUserDefaults standardUserDefaults];
        NSData *jsonData = [payLoadString dataUsingEncoding:NSUTF8StringEncoding];
        NSDictionary *jsonDic = [NSJSONSerialization JSONObjectWithData:jsonData
                                                                options:NSJSONReadingMutableContainers
                                                                  error:nil];
        STPushModel *model = [STPushModel modelObjectWithDict:jsonDic];
        [NSKeyedArchiver archiveRootObject:model toFile:KRAPI_PUSH_DATA];
        //如果应用程序在前台 就显示客服提示框
        if (application.applicationState == UIApplicationStateActive) {
            self.topView.model = model;
            [self displayPushView];    //此方法 的实现 在上一步中 就是展示提示框出来
        }

}

然后这些工作做好了之后 就是你需要在个推的后台 配置推送证书  这个配置的步骤 大家可以到个推官网去参考文档 配置 

这里我假设 你已经配置到证书了  经过上面的步骤 我们的远程推送通知的方法 基本完成 现在我们运行 测试下 你会发现即使在前台 有新消息推送的时候 顶部也会弹出和系统一样的提示框 点击 跳转到对应的页面的方法逻辑根据你的需要 去做跳转处理

测试效果如下：

用户在后台 收到的消息提示如下：

用户在前台 收到的消息提示如下：
