我试图在UIView中嵌入一个AVPlayer并从网址播放mp4视频文件.问题是我只收到一个黑色的空白视图(见截图)
在以前的iOS版本中,它对我有用,但自从升级到iOS9后我遇到了这个问题.
我的.h文件如下所示：
@interface ViewController : UIViewController @property (strong,nonatomic) IBOutlet UIView *viewPlayerContainer;
而在我的实现文件中,我有以下内容：
@import AVFoundation;
@import AVKit;
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
NSURL *url = [NSURL URLWithString:@"http://techslides.com/demos/sample-videos/small.mp4"];
AVURLAsset *asset = [AVURLAsset assetWithURL: url];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset: asset];
AVPlayer * player = [[AVPlayer alloc] initWithPlayerItem: item];
[playerViewController.view setFrame:CGRectMake(0,_viewPlayerContainer.bounds.size.width,_viewPlayerContainer.bounds.size.width)];
playerViewController.showsPlaybackControls = NO;
[_viewPlayerContainer addSubview:playerViewController.view];
[player play];
}
我错过了什么吗？
提前致谢！
解决方法
@implementation ViewController{
AVPlayerViewController *playerViewController;
}
- (void)viewDidLoad {
[super viewDidLoad];
playerViewController = [[AVPlayerViewController alloc] init];
}
- (IBAction)playVideo:(id)sender {
NSURL *url = [NSURL URLWithString:@"http://techslides.com/demos/sample-videos/small.mp4"];
AVURLAsset *asset = [AVURLAsset assetWithURL: url];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset: asset];
AVPlayer * player = [[AVPlayer alloc] initWithPlayerItem: item];
playerViewController.player = player;
[playerViewController.view setFrame:CGRectMake(0,self.view.bounds.size.width,self.view.bounds.size.width)];
playerViewController.showsPlaybackControls = YES;
[self.view addSubview:playerViewController.view];
[player play];
}
