NSString *urlAddress = @"assets-library://asset/asset.mov?id=1000000023&ext=mov"; NSURL *theURL = [NSURL URLWithString:urlAddress]; MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:theURL];

推荐答案

我也遇到了问题，并得到了解决方案。我使用了以下代码，它对我有用。 urlAddress 是 ALAssetsLibrary 的视频网址。

I was also getting problem, and got the solution. I used the following code and it worked for me. The urlAddress is the url for the video by ALAssetsLibrary.

-(void)playVideo:(NSString *)urlAddress{ NSString *newUrl = [[NSString alloc] initWithFormat:@"%@",urlAddress]; NSURL *theURL = [NSURL URLWithString:newUrl]; //player = [[MPMoviePlayerController alloc] init]; [player setContentURL:theURL]; [player prepareToPlay]; [player play]; }
