iOS弹框

IOS 弹框 如果直接弹出一个自定义的视图 可以选用第三方：

MJPopup

弹出：

if(!bandview)

    {

        bandview=[[[NSBundle mainBundle]loadNibNamed:@"bandView" owner:selfoptions:nil] firstObject];

        bandview.bdelagate=self;

        [bandview setFrame:CGRectMake(0, 0, 320, 160)];

    }

    int offset=ISIPhone5?100:50;

    [self presentPopupView:bandview animationType:MJPopupViewAnimationFadeoffset:offset];

收起

[self dismissPopupViewControllerWithanimationType:MJPopupViewAnimationFade];

一般的菜单弹出可用

KxMenu

 NSArray *menuItems =

    @[

      [KxMenuItem menuItem:@"明细统计方式"

                     image:nil

                    target:nil

                    action:NULL],

      

      [KxMenuItem menuItem:@"现金"

                     image:[UIImageimageNamed:@"action_icon"]

                    target:self

                   action:@selector(pushMenuItem:)],

      

      [KxMenuItem menuItem:@"余额"

                     image:[UIImageimageNamed:@"check_icon"]

                    target:self

                   action:@selector(pushMenuItem:)],

      

      [KxMenuItem menuItem:@"POS"

                     image:[UIImageimageNamed:@"reload"]

                    target:self

                   action:@selector(pushMenuItem:)]

      ];

    

    KxMenuItem *first = menuItems[0];

    first.foreColor = [UIColorcolorWithRed:47/255.0f green:112/255.0fblue:225/255.0f alpha:1.0];

    first.alignment = NSTextAlignmentCenter;

    

    CGRect rect=button.frame;

    CGFloat height=0.0;

    if(IOS7>=7.0)

    {

        height=64;

    }

    else

    {

        height=0.0;

    }

    [KxMenu showMenuInView:self.view

                 fromRect:CGRectMake(rect.origin.x, rect.origin.y, rect.size.width, height)

                 menuItems:menuItems];

点击事件实现：

- (void) pushMenuItem:(KxMenuItem*)sender

--------------------------------

今天在看开源中国时看到别人写的一个demo很帅啊，是一个垂直方向展示的弹出菜单，链接地址为：IOS弹出式菜单KxMenu 同时文中也附上了github的地址，在此热泪感谢原作者，我们来试用一下。

因为学习了也有一段日子了，所以我们不能只做一个拖控件的，所以今天的这个demo，我们用纯代码方式来实现一下。

首先，创建一个空的项目。

然后我们添加一个Object-C类，不添加xib文件。

之后我们把KxMenu类拷贝到我们的项目里，并且import进来。

再然后在我们自己的Obj－C类中添加一个UIButton，同时要把KxMenu初始化，我们来具体看下ViewController.m中的代码：

#import "ViewController.h"
#import "KxMenu.h"

@interface ViewController ()

@end

@implementation ViewController
{
    UIButton *_btn1;
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

-(void)loadView
{
    CGRect frame = [[UIScreen mainScreen] applicationFrame];

    self.view = [[UIView alloc] initWithFrame:frame];
    self.view.backgroundColor = [UIColor whiteColor];
    self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;

    _btn1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    _btn1.frame = CGRectMake(5, 5, 100, 50);
    [_btn1 setTitle:@"KxMenu Test" forState:UIControlStateNormal];
    [_btn1 addTarget:self action:@selector(showMenu:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:_btn1];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)showMenu:(UIButton *)sender
{
    NSArray *menuItems =
    @[

      [KxMenuItem menuItem:@"ACTION MENU Test"
                     image:nil
                    target:nil
                    action:NULL],

      [KxMenuItem menuItem:@"Share this"
                     image:[UIImage imageNamed:@"action_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Check menu"
                     image:[UIImage imageNamed:@"check_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Reload page"
                     image:[UIImage imageNamed:@"reload"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Search"
                     image:[UIImage imageNamed:@"search_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Go home"
                     image:[UIImage imageNamed:@"home_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],
      ];

    KxMenuItem *first = menuItems[0];
    first.foreColor = [UIColor colorWithRed:47/255.0f green:112/255.0f blue:225/255.0f alpha:1.0];
    first.alignment = NSTextAlignmentCenter;

    [KxMenu showMenuInView:self.view
                  fromRect:sender.frame
                 menuItems:menuItems];
}

- (void) pushMenuItem:(id)sender
{
    NSLog(@"%@", sender);
}
@end

然后，我们要在ETAppDelegate.h中添加如下的代码：

#import <UIKit/UIKit.h>

@class ViewController;//添加ViewController类

@interface ETAppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;//ViewController

@end

接下来我们就要在ETAppDelegate.m中加载我们自己的ViewController，导入ViewController.h

#import "ViewController.h"

然后修改application方法，如下：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.viewController = [[ViewController alloc] init];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

OK，基本上初步试用的一个demo就完成了，下面是运行效果：
