NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"/one.mp4"]; NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath]; MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:mediaPath]]; [[moviePlayer view] setFrame:[[self view] bounds]]; [[self view] addSubview: [moviePlayer view]]; moviePlayer.scalingMode = MPMovieScalingModeAspectFit; [moviePlayer play];
这很奇怪,但是如果你让你的MPMoviePlayerController成为一个属性而不是一个局部变量似乎没问题.似乎在幕后发生了一些事情.我认为这与ARC有关.你在用ARC吗?
这也是你过度添加路径的问题:
// You've already got the full path to the documents directory here. NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"/one.mp4"]; // Now you're appending the full path to the documents directory to your bundle path NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath];
当我在模拟器中运行代码时,路径如下所示:
/Users/mlong/Library/Application Support/iPhone Simulator/5.1/Applications/8CFB9B94-BD6A-442C-A525-573FE343506D/VidoePlayer.app/Users/mlong/Library/Application Support/iPhone Simulator/5.1/Applications/8CFB9B94-BD6A-442C-A525-573FE343506D/Documents/one.mp4
它应该是这样的:
/Users/mlong/Library/Application Support/iPhone Simulator/5.1/Applications/8CFB9B94-BD6A-442C-A525-573FE343506D/Documents/one.mp4
所以只需删除此行:
NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath];
然后将播放器实例化更改为:
_moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:filePath]]; [[_moviePlayer view] setFrame:[[self view] bounds]]; [[self view] addSubview: [_moviePlayer view]]; _moviePlayer.scalingMode = MPMovieScalingModeAspectFit; [_moviePlayer play];
因此,您应该将MPMoviePlayerController添加为包含视图控制器的属性.
