如果你不想使用 assest 库，这里是代码

 NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
 NSString *videoFile = [documentDirectory stringByAppendingPathComponent:@"video.mp4"];
 UISaveVideoAtPathToSavedPhotosAlbum(videoFile, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);


- (void)video:(NSString *) videoPath didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo {
     if(error)
           NSLog(@\"didFinishSavingWithError: %@\", error);
}
