MPMoviePlayerViewController不会播放电影，立即启动和closures

我试图用MPMoviePlayerViewController播放video，我介绍了MPMoviePlayerViewController，但1秒后，他正在解散。

这是我的代码：

。H：

#import <MediaPlayer/MediaPlayer.h> @property (strong, nonatomic) MPMoviePlayerViewController *moviePlayerViewController; 

.M：

 - (void)playmovie { NSString *databaseName = @"NO.mp4"; NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentDir = [documentPaths objectAtIndex:0]; NSString *databasePath = [documentDir stringByAppendingPathComponent:databaseName]; NSURL *movieURL = [NSURL fileURLWithPath:databasePath]; UIGraphicsBeginImageContext(CGSizeMake(1,1)); self.moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL]; [self presentMoviePlayerViewControllerAnimated:self.moviePlayerViewController]; UIGraphicsEndImageContext(); [self.moviePlayerViewController.moviePlayer prepareToPlay]; [self.moviePlayerViewController.moviePlayer play]; } 

请告诉我我做错了什么。

提前致谢！

将url更改为下面的代码

 NSString *path =[[NSBundle mainBundle] pathForResource:@"NO" ofType:@"mp4"]; NSURL *url = [NSURL fileURLWithPath:path]; 

试试这个你会成功的。

尝试这个..

 NSString *databaseName = @"NO.mp4"; NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentDir = [documentPaths objectAtIndex:0]; NSString *databasePath = [documentDir stringByAppendingPathComponent:databaseName]; NSURL *url = [NSURL fileURLWithPath:databasePath]; MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; moviePlayer.view.frame = CGRectMake(0, 0, 500, 500); moviePlayer.moviePlayer.shouldAutoplay=YES; moviePlayer.moviePlayer.controlStyle = MPMediaTypeMusicVideo; [moviePlayer.moviePlayer setFullscreen:YES animated:YES]; [self.view addSubview:moviePlayer.view]; [moviePlayer.moviePlayer play];
