ios - 如何在 Controller 的 subview Controller 中为按钮添加目标

Question

一个有2个 Controller

@interface PlayVideoController : UIViewController

@property (strong, nonatomic) IBOutlet UIButton *playButton;@property (strong, nonatomic) IBOutlet UIButton *exportButton;- (IBAction)actionPlay:(id)发件人；和

@interface HomeController : CommonVideoViewController

在 Homecontroller 中有 2 个方法

    - (void)selectedVideoComplete:(NSDictionary *)infoVideo 
    playController = [self.storyboard instantiateViewControllerWithIdentifier:@"PlayVideoController"];
//    playController = [[PlayVideoController alloc]initWithNibName:@"View" bundle:nil];

//    [playController.playtButton addTarget:playController action:@selector(playAction) forControlEvents:UIControlEventTouchUpInside];
    playController.urlMovie = [infoVideo objectForKey:UIImagePickerControllerMediaURL];
    [self.view addSubview:playController.view];
     NSLog(@"_____ %@",playController.playButton);
    [playController.view addSubview:btn];

- (void)playAction {
    [playController.player play];
}

为什么这段代码不起作用

[playController.playtButton addTarget:playController action:@selector(playAction) forControlEvents:UIControlEventTouchUpInside];

我正在使用 Storyboard和 xib 文件进行测试

谢谢

目前您正在HomeController中实现playAction方法，它需要在您的PlayVideoController中实现。

或者，如果您的 playAction 方法只执行代码显示的操作，只需按如下方式设置操作:

[playController.playButton addTarget:playController.player action:@selector(play) forControlEvents:UIControlEventTouchUpInside];

希望这对您有所帮助!
