iphone - iOS-UISaveVideoAtPathToSavedPhotosAlbum如何返回已保存的视频路径？

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

    NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];


    //get the videoURL
    NSString *tempFilePath = [videoURL path];


    if ( UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(tempFilePath))
    {
      // Copy it to the camera roll.
      UISaveVideoAtPathToSavedPhotosAlbum(tempFilePath, self, @selector(video:didFinishSavingWithError:contextInfo:), tempFilePath);
    }
}

我使用UISaveVideoAtPathToSavedPhotosAlbum保存录制的视频。我想知道专辑中保存录制视频的绝对路径。

如何获得保存的路径？ UISaveVideoAtPathToSavedPhotosAlbum不返回任何内容。

并且在回调函数video:didFinishSavingWithError:contextInfo:中仍然没有路径信息。

最佳答案

据我所知..您无法获取相册中保存的视频的路径。如果要从应用程序中重播文件列表。您可以将所有视频包含在您的应用程序中。

以下是将示例视频放入didFinishPickingMedia中，以将视频存储在辅助文档中。以便您可以对其进行跟踪。

   NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
    NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%d", 1]];
    NSString *fileName = [NSString stringWithFormat:@"%@ :%@.%@", itsIncidentType, [dateFormatter stringFromDate:incidentDate], @"mp4"];
    [dateFormatter release];
    if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
        [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
    NSURL *videoURL = [imageInfo objectForKey:UIImagePickerControllerMediaURL];
    NSData *webData = [NSData dataWithContentsOfURL:videoURL];
    self.itsVideoName = fileName;
    [webData writeToFile:[NSString stringWithFormat:@"%@/%@",dataPath,fileName] atomically:TRUE];

希望这对您有帮助。
