如何从资源库播放视频文件？我有文件的网址，如

How to play the video file from assets library? I have the URL of file like

"assets-library://asset/asset.MOV?id=1000000023&ext=MOV"

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]; 

}
