Question

a有2个控制器

@interface PlayVideoController : UIViewController

@property（强，非原子）IBOutlet UIButton * playButton; @property（强，非原子）IBOutlet UIButton * exportButton; - （IBAction）actionPlay：（id）sender; 和

@interface HomeController : CommonVideoViewController

Homecontroller中的

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];
}

为什么此代码不起作用

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

我正在使用storyboard和xib文件进行测试

目前，您正在playAction中实施HomeController方法，并且需要在PlayVideoController中实施。

或者，如果您的playAction方法仅执行代码显示的操作，请按以下步骤设置操作：

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

希望这有帮助！
