如何通过 ImagePickerViewController 为录制的视频资产 url？

Question

实际上，当在设备上以纵向或横向模式捕获视频时，我想解决视频方向问题。为了解决这个问题，我有这个链接

How to fix video orientation issue in iOS

而且我也有 google 来解决方向问题，每种方法都需要一个资产 url。所以请告诉我如何在从相机捕获视频时获取参考 url。

目前我收到UIImagePickerControllerMediaURL

 - (void) imagePickerController: (UIImagePickerController *) picker
     didFinishPickingMediaWithInfo: (NSDictionary *) info
 { 
    NSUrl * url =[info objectForKey:UIImagePickerControllerMediaURL];
    NSlog("Url is ::::%@",url);
 }

但我想为最近录制的视频获取UIImagePickerControllerReferenceURL。请指导我。

你好，你可以试试这个。它会给出视频的引用网址。

// For responding to the user accepting a newly-captured picture or movie
- (void)video:(NSString*)videoPath didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo
{

        NSString *str=@"file://localhost";
        NSString *appendPath=[str stringByAppendingString:videoPath];

        NSURL *urlVideo = [NSURL URLWithString:[appendPath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];


            AVURLAsset *asset = [AVURLAsset assetWithURL: urlVideo];
            Float64 duration = CMTimeGetSeconds(asset.duration);

            NSString *strTime = [[NSString alloc] initWithString:[NSString stringWithFormat:@"%f",duration]];

            DLog(@"strTime ==%@",strTime);
}

谢谢
