我找到了答案

这里保存了视频

    NSString *stringURL = @"http://videoURL";
NSURL  *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
NSString  *documentsDirectory ;
if ( urlData )
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
   documentsDirectory = [paths objectAtIndex:0];

    NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"videoName.mp4"];
    [urlData writeToFile:filePath atomically:YES];

}

此代码用于播放其目录中的视频

and this code is for playing the video form its directory

    NSString  *filepath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"videoName.mp4"];

//video URL
NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[moviePlayerController play];
