无法使用 AVPlayerViewController

问题描述

我正在尝试在我的视图启动时显示视频。但是我一直让应用程序试图在目标（我的视图控制器）上呈现一个 nil 模态视图控制器。

这是我的代码。

@property (nonatomic,retain) AVPlayerViewController *moviePlayer;

-(void) viewWillAppear:(BOOL)animated{
    
    NSString *documentsDirectory31 = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES) objectAtIndex:0];
    NSString *documentaryDirectory23 = [documentsDirectory31 stringByAppendingPathComponent:@"ChildOne.txt"];
    
    if([[NSFileManager defaultManager] fileExistsAtPath: documentaryDirectory23]) {
        self.user.text =[NSString stringWithContentsOfFile:documentaryDirectory23 encoding:NSUTF8StringEncoding error:NULL];
    }
    self.sharingtext.hidden = YES;
    
   AVAudioSession *session = [AVAudioSession sharedInstance];
    [session setCategory:AVAudioSessionCategoryPlayback error:nil];
    [session setActive:YES error:nil];
    
    NSString *audioName = [myDictionary objectForKey:@"photoVideokey"];
    NSArray *pathsa = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,YES);
    NSString *documentsDirectorya = [pathsa objectAtIndex:0];
    NSString *slash = [documentsDirectorya stringByAppendingPathComponent:@"/"];
    NSString *documentsDirectory1 = [slash stringByAppendingPathComponent:self.user.text];
    
    //Get a full path to the image in the documents directory.
    NSString *fullPath = [documentsDirectory1 stringByAppendingPathComponent:@"/Movie"];
    
    
  NSString *fullPatha = [fullPath stringByAppendingPathComponent:audioName];
    url = [NSURL fileURLWithPath:fullPatha];
   
    NSLog(@"fullPatha:%@",fullPatha);
  NSData *videoData = [[NSData alloc] initWithContentsOfURL:url];
    
    AVPlayerItem* playerItem = [AVPlayerItem playerItemWithURL:url];
       AVPlayer* playVideo = [[AVPlayer alloc] initWithPlayerItem:playerItem];
    
    
    self.sharingImage = [UIImage imageWithData:videoData];
    //AVPlayerViewController *playerViewController = [AVPlayerViewController new];
   
    // frame must match parent view
    [self.view insertSubview: [moviePlayer view]atIndex:4];
    if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){
        if([UIScreen mainScreen].bounds.size.height == 568.0){
            moviePlayer.view.frame = CGRectMake(0,320,568);
        }
        
       else if([UIScreen mainScreen].bounds.size.height == 667.0){
            moviePlayer.view.frame = CGRectMake(0,375,667);
        }
        
       else if([UIScreen mainScreen].bounds.size.height == 736.0){
            moviePlayer.view.frame = CGRectMake(0,414,736);
        }
       else if([UIScreen mainScreen].bounds.size.height == 812.0){
              //11pro76*1.17,3*1.69 OK!
           NSLog(@"THIS IS BEING CALLED 11 pro/12mini/SE2");
           moviePlayer.view.frame = CGRectMake(0,self.view.frame.size.width,self.view.frame.size.height);
        }
       else if([UIScreen mainScreen].bounds.size.height == 896.0){
           NSLog(@"THIS IS BEING CALLED 11");
                   //1176*1.29,3*1.867 OK!
           moviePlayer.view.frame = CGRectMake(0,self.view.frame.size.height);
       }
       else if([UIScreen mainScreen].bounds.size.height == 844.0){
           NSLog(@"THIS IS BEING CALLED 12/pro");
                   //1176*1.29,self.view.frame.size.height);
       }
       else if([UIScreen mainScreen].bounds.size.height == 926.0){
           NSLog(@"THIS IS BEING CALLED 12PROMAX");
                   //1176*1.29,self.view.frame.size.height);
       }
        
        
        else {
            [[moviePlayer view] setFrame:[self.view bounds]];
        }
        
    }
    
    moviePlayer.player = playVideo;
    [self presentViewController:moviePlayer animated:YES completion:^{
        [self->moviePlayer.player play];
    }];
  }

我知道该文件存在于路径中，因为当我拍摄并保存它时，我可以将其共享到 iMovie。
我不确定为什么模态视图为零。 谁能帮帮我。
