iphone - 如何从 UISaveVideoAtPathToSavedPhotosAlbum 检索视频

Question

在我的应用程序中，我使用 UISaveVideoAtPathToSavedPhotosAlbum 将视频保存到照片库。我正在获取视频的路径，但无法播放该视频。任何人都可以帮助我解决如何检索保存的视频的问题。提前致谢。我使用了下面显示的代码。

-(IBAction) getPhoto:(id) sender {
    UIImagePickerController * picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;

  if((UIButton *) sender == choosePhotoBtn) {
    picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    picker.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, (NSString *)kUTTypeImage, nil];

} else {
    picker.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, (NSString *)kUTTypeImage, nil];
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    }

[self presentModalViewController:picker animated:YES];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

      NSString *tempFilePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
      UISaveVideoAtPathToSavedPhotosAlbum(tempFilePath, self,  @selector(video:didFinishSavingWithError:contextInfo:), nil);
      NSLog(@"temp path %@",tempFilePath);
      [picker dismissModalViewControllerAnimated:YES];

}

NSURL *url = [NSURL fileURLWithPath:tempFilePath];并使用以下网址播放网址:“MPMoviePlayerController”
