看到网上很多都说，avplayer的layer没有创建，所以无法加载页面，估计是探路人一个人理解错了，导致很多人理解错了吧。其实不是这样的，是avplayerviewcontroller没有经过viewdidappear 直接add，导致avplayerviewcontroller的view 不能获得frame的大小，导致我们感觉没有add上去，其实只要设置一下view的frame就好了。
方法一：
注意点：
1._controller要声明成全局变量，不然无法控制播放。不声明成全局变量，要想办法retain一下，比如，self addchildcontrollers.
2.addobserver的时候,不要传object，这时候传递的object是指的发送方，而不是参数。当postnotification的对象与object不一致时，是不会响应通知方法的。
_controller= [[AVPlayerViewController alloc]init];
AVPlayerItem *model =[[AVPlayerItem alloc]initWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"bhl912.mov" ofType:nil]]];
AVPlayer *player = [AVPlayer playerWithPlayerItem:model];
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(playFinished:) name:AVPlayerItemDidPlayToEndTimeNotification object:nil];
[_controller setPlayer:player];
_controller.view.frame = self.view.bounds;
_controller.videoGravity = AVLayerVideoGravityResizeAspect;
_controller.showsPlaybackControls = YES;
[self.view addSubview:_controller.view];
[_controller.player play];
方法二
- (void)playeVideo
{
MoviePlayerViewController* avPlayer = [[MoviePlayerViewController alloc] init];
[avPlayer setName:@"bhl912.mov"];
[self presentViewController:avPlayer animated:YES completion:nil];
}
#import@interface MoviePlayerViewController : AVPlayerViewController
@property(nonatomic,strong)NSString *name ;
@end
@implementation MoviePlayerViewController
-(void)setName:(NSString *)name
{
_name = name;
NSString *playString = [[NSBundle mainBundle] pathForResource:name ofType:nil];
//视频播放的url
NSURL *playerURL = [NSURL fileURLWithPath:playString];
self.player = [[AVPlayer alloc] initWithURL:playerURL];
self.videoGravity = AVLayerVideoGravityResizeAspect;
}
- (void)viewDidLoad {
[super viewDidLoad];
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(dismiss) name:AVPlayerItemDidPlayToEndTimeNotification object:nil];
// Do any additional setup after loading the view.
}
-(void)dismiss
{
[self dismissViewControllerAnimated:YES completion:nil];
}
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear: animated];
[self.player play];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)dealloc
{
[[NSNotificationCenter defaultCenter]removeObserver:self];
}
