Question

在我的APP中使用UISaveVideoAtPathToSavedPhotosAlbum将视频保存到photolibrary。我正在获取视频的路径，但我无法播放此视频。任何1可以帮助我解决如何检索已保存的视频。谢谢。我使用下面的代码。

-(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];

}

Answer 1

此函数返回的路径需要后缀。试试这个

NSString *videoPath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
NSURL *videoURL = [NSURL URLWithString:[NSString stringWithFormat:@"file://localhost%@", videoPath]];

Answer 2

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