如何在 MPMoviePlayerController 上添加 UIImageView |iOS |目标 C [英] How to add a UIImageView over a MPMoviePlayerController | iOS | Objective C

问题描述

I have a controller where I displays a video using MPMoviePlayerController. And I need to put an image over the video.

I am trying with the following code, but it doesn't show up. What I am missing?

// method to play the video
- (void)playVideoInLoopMode:(BOOL)loop {
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"myvideo" ofType:@"m4v"]];

    MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:url];
    mp.controlStyle = MPMovieControlStyleNone;

    if (loop) {
        mp.repeatMode = MPMovieRepeatModeOne;        
    }

    mp.view.frame = CGRectMake(0.0, 0.0, self.view.bounds.size.width, self.view.bounds.size.height);
    self.player = mp;
    [self.view addSubview:self.player.view];

    [self.player prepareToPlay];

    [self.player play];
}

// method to add the image
- (void) addImageLayer {
    image = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"myimage"]];
    image.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
    [self.view addSubview:image];
}

First I am running the video with the method: [self playVideoInLoopMode:YES] and after 5 seconds I am trying to put the image layer with the method [self addImageLayer];

In my AppDelegate.h I have this code in the didFinishLaunchingWithOptions:

 MyViewController *myVC = [[MyViewController alloc] initWithNibName:@"MyView" bundle:nil];

    [self.window addSubview:myVC.view];
    [self.window makeKeyAndVisible];

解决方案

Try adding the image view to the mp.view and then u add the mp.view to the general view for example if the image will be always the same u can add it in your starting code and delete the method to add the view...

// method to play the video
- (void)playVideoInLoopMode:(BOOL)loop 
{
   NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"myvideo" ofType:@"m4v"]];

   MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:url];
   mp.controlStyle = MPMovieControlStyleNone;

   if (loop) 
   {
       mp.repeatMode = MPMovieRepeatModeOne;        
   }

   mp.view.frame = CGRectMake(0.0, 0.0, self.view.bounds.size.width, self.view.bounds.size.height);
   self.player = mp;
   [self.view addSubview:self.player.view];
   image = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"myimage.png"]];
   image.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
   [self.player addSubview:image];
   [self.player prepareToPlay];
   [self.player play];
}
