ios - 点击手势在 imageView 中不起作用，但它在另一个 View 中起作用

Question

我在图像和视频叠加层中工作，因为我放置了一个 ImageView ，我将 tapGestureRecognizer 分配给该 ImageView 它不起作用，对于视频我放置了一个 MPMoviePlayerController 并将 tapGestureRecognizer 设置为它，这个工作正常但是仅 ImageView 不起作用。下面是我的代码

- (void)viewDidLoad {
    [super viewDidLoad];
    videoimg=[[UIImageView alloc]init];//OvelayImage
    videoimg.image=[UIImage imageNamed:@"fb.png"];
    videoimg.userInteractionEnabled=YES;
    videoimg.multipleTouchEnabled=YES;
    [self.imgView bringSubviewToFront:videoimg];

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imagePan:)];

    tap.numberOfTapsRequired=1;
    tap.numberOfTouchesRequired=1;

    [videoimg addGestureRecognizer:tap];
    [self.imgView addSubview:videoimg];//add the overlay image to Main imageView 
    [self.videoPlayerView.view addSubview:videoimg];//MPMoviePlayerController-add the overlay image to VideoView
}

//Gesture
-(void)imagePan:(UITapGestureRecognizer*)ges{

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Image" message:@"FB Image Clicked..."
                                                   delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
}

Answer 1

videoimg=[[UIImageView alloc]init];
videoimg.image=[UIImage imageNamed:@"fb.png"];
videoimg.userInteractionEnabled=YES;

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imagePan:)];
[videoimg setGestureRecognizers:[NSArray arrayWithObject:tap]];
tap.numberOfTapsRequired=1;
[self.videoPlayerView.view addSubview:videoimg];
