iOS10全新推送功能的实现

从iOS8.0开始推送功能的实现在不断改变，功能也在不断增加，iOS10又出来了一个推送插件的开发（见最后图），废话不多说直接上代码：

在开始之前需要打开一个推送开关,不然无法获取deviceToken,老项目或者出现deviceToken无效的情况：如图：

打开后会生成entitlements文件，需要有APS Environment

#import <UserNotifications/UserNotifications.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    /* APP未启动，点击推送消息的情况下 iOS10遗弃UIApplicationLaunchOptionsLocalNotificationKey，使用代理UNUserNotificationCenterDelegate方法didReceiveNotificationResponse:withCompletionHandler:获取本地推送
     */
//    NSDictionary *localUserInfo = launchOptions[UIApplicationLaunchOptionsLocalNotificationKey];
//    if (localUserInfo) {
//        NSLog(@"localUserInfo:%@",localUserInfo);
//        //APP未启动，点击推送消息
//    }
    NSDictionary *remoteUserInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
    if (remoteUserInfo) {
        NSLog(@"remoteUserInfo:%@",remoteUserInfo);
        //APP未启动，点击推送消息，iOS10下还是跟以前一样在此获取
    }
    [self registerNotification];
    return YES;
}

注册推送方法的改变：

新增库 #import <UserNotifications/UserNotifications.h>  推送单列UNUserNotificationCenter 等API

- (void)registerNotification{
    /*
     identifier：行为标识符，用于调用代理方法时识别是哪种行为。
     title：行为名称。
     UIUserNotificationActivationMode：即行为是否打开APP。
     authenticationRequired：是否需要解锁。
     destructive：这个决定按钮显示颜色，YES的话按钮会是红色。
     behavior：点击按钮文字输入，是否弹出键盘
     */
    UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action1" title:@"策略1行为1" options:UNNotificationActionOptionForeground];
    /*iOS9实现方法
    UIMutableUserNotificationAction * action1 = [[UIMutableUserNotificationAction alloc] init];
    action1.identifier = @"action1";
    action1.title=@"策略1行为1";
    action1.activationMode = UIUserNotificationActivationModeForeground;
    action1.destructive = YES;
     */
    
    UNTextInputNotificationAction *action2 = [UNTextInputNotificationAction actionWithIdentifier:@"action2" title:@"策略1行为2" options:UNNotificationActionOptionDestructive textInputButtonTitle:@"textInputButtonTitle" textInputPlaceholder:@"textInputPlaceholder"];
    /*iOS9实现方法
        UIMutableUserNotificationAction * action2 = [[UIMutableUserNotificationAction alloc] init];
        action2.identifier = @"action2";
        action2.title=@"策略1行为2";
        action2.activationMode = UIUserNotificationActivationModeBackground;
        action2.authenticationRequired = NO;
        action2.destructive = NO;
        action2.behavior = UIUserNotificationActionBehaviorTextInput;//点击按钮文字输入，是否弹出键盘
    */
    
    UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"Category1" actions:@[action2,action1]  intentIdentifiers:@[@"action1",@"action2"] options:UNNotificationCategoryOptionCustomDismissAction];
    //        UIMutableUserNotificationCategory * category1 = [[UIMutableUserNotificationCategory alloc] init];
    //        category1.identifier = @"Category1";
    //        [category1 setActions:@[action2,action1] forContext:(UIUserNotificationActionContextDefault)];
    
    UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:@"action3" title:@"策略2行为1" options:UNNotificationActionOptionForeground];
    //        UIMutableUserNotificationAction * action3 = [[UIMutableUserNotificationAction alloc] init];
    //        action3.identifier = @"action3";
    //        action3.title=@"策略2行为1";
    //        action3.activationMode = UIUserNotificationActivationModeForeground;
    //        action3.destructive = YES;
    
    UNNotificationAction *action4 = [UNNotificationAction actionWithIdentifier:@"action4" title:@"策略2行为2" options:UNNotificationActionOptionForeground];
    //        UIMutableUserNotificationAction * action4 = [[UIMutableUserNotificationAction alloc] init];
    //        action4.identifier = @"action4";
    //        action4.title=@"策略2行为2";
    //        action4.activationMode = UIUserNotificationActivationModeBackground;
    //        action4.authenticationRequired = NO;
    //        action4.destructive = NO;
    
    UNNotificationCategory *category2 = [UNNotificationCategory categoryWithIdentifier:@"Category2" actions:@[action3,action4]  intentIdentifiers:@[@"action3",@"action4"] options:UNNotificationCategoryOptionCustomDismissAction];
    //        UIMutableUserNotificationCategory * category2 = [[UIMutableUserNotificationCategory alloc] init];
    //        category2.identifier = @"Category2";
    //        [category2 setActions:@[action4,action3] forContext:(UIUserNotificationActionContextDefault)];
    
    
    [[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:category1,category2, nil]];
    [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
        NSLog(@"completionHandler");
    }];
    /*iOS9实现方法
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:[NSSet setWithObjects: category1,category2, nil]];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    */
    [[UIApplication sharedApplication] registerForRemoteNotifications];
    
    
    [UNUserNotificationCenter currentNotificationCenter].delegate = self;
}

代理方法的改变：

一些本地和远程推送的回调放在了同一个代理方法

#pragma mark -

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings NS_AVAILABLE_IOS(8_0) __TVOS_PROHIBITED{
    NSLog(@"didRegisterUserNotificationSettings");
}

    NSLog(@"deviceToken:%@",deviceToken);
    NSString *deviceTokenSt = [[[[deviceToken description]
                                 stringByReplacingOccurrencesOfString:@"<" withString:@""]
                                stringByReplacingOccurrencesOfString:@">" withString:@""]
                               stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"deviceTokenSt:%@",deviceTokenSt);
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error NS_AVAILABLE_IOS(3_0){
    NSLog(@"didFailToRegisterForRemoteNotificationsWithError:%@",error);
}

/*iOS9使用方法
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo NS_DEPRECATED_IOS(3_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate willPresentNotification:withCompletionHandler:] or -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:] for user visible notifications and -[UIApplicationDelegate application:didReceiveRemoteNotification:fetchCompletionHandler:] for silent remote notifications"){
    
}
*/

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
    NSLog(@"willPresentNotification:%@",notification.request.content.title);
    
    // 这里真实需要处理交互的地方
    // 获取通知所带的数据
    NSString *notMess = [notification.request.content.userInfo objectForKey:@"aps"];
    
}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
    //在没有启动本App时，收到服务器推送消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮
    NSString *notMess = [response.notification.request.content.userInfo objectForKey:@"aps"];
    NSLog(@"didReceiveNotificationResponse:%@",response.notification.request.content.title);
//    response.notification.request.identifier
}

//远程推送APP在前台
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
    NSLog(@"didReceiveRemoteNotification:%@",userInfo);
}

/*
- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler NS_DEPRECATED_IOS(8_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:]") __TVOS_PROHIBITED
{
    
}
*/
/*
// 本地通知回调函数，当应用程序在前台时调用
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification NS_DEPRECATED_IOS(4_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate willPresentNotification:withCompletionHandler:] or -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:]") __TVOS_PROHIBITED{

    // 这里真实需要处理交互的地方
    // 获取通知所带的数据
    NSString *notMess = [notification.userInfo objectForKey:@"aps"];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"本地通知(前台)"
                                                    message:notMess
                                                   delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];
    
    // 更新显示的徽章个数
    NSInteger badge = [UIApplication sharedApplication].applicationIconBadgeNumber;
    badge--;
    badge = badge >= 0 ? badge : 0;
    [UIApplication sharedApplication].applicationIconBadgeNumber = badge;
    
    // 在不需要再推送时，可以取消推送
    [FirstViewController cancelLocalNotificationWithKey:@"key"];

}


- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler NS_DEPRECATED_IOS(8_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:]") __TVOS_PROHIBITED
{
    //在非本App界面时收到本地消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮，notification为消息内容
    NSLog(@"%@----%@",identifier,notification);
    completionHandler();//处理完消息，最后一定要调用这个代码块
}

还有推送插件开发: 类似iOS tody widget插件开发
