当用户录制视频然后单击选择时,我的应用程序崩溃了。这是我的代码:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        picker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
        //picker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:picker.sourceType];
        picker.allowsEditing = NO;
        picker.delegate = self;
        picker.videoQuality = UIImagePickerControllerQualityTypeMedium;
        [self presentModalViewController:picker animated:YES];




-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
   // [self dismissModalViewControllerAnimated:YES];
    AppDelegate *del = [[UIApplication sharedApplication]delegate];

    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];


    moviePath = [[info objectForKey:UIImagePickerControllerMediaURL]path];..//using this for upload

    del.globalMoviePath = moviePath;

    if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0)== kCFCompareEqualTo)
    {

        moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

        del.globalMoviePath = moviePath;


        picker.videoMaximumDuration = 60.0f;
        picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;


        NSLog(@"nrgkrg===>%@",moviePath);

       videoUrl=(NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];
         NSLog(@"Urlllll===>%@",videoUrl);

        videoData = [NSData dataWithContentsOfURL:videoUrl];

        del.globalMoviePath = moviePath;

        NSLog(@"video is====>%@",del.globalMoviePath);

        MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoUrl];
        UIImage *thumbnail = [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame];
        [player stop];

        videoImage = [[UIImageView alloc]initWithImage:thumbnail];

        //NSLog(@"imegsvideo====>%@",thumbnail);


        //if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath))
        //{
          //  UISaveVideoAtPathToSavedPhotosAlbum (moviePath, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);
       // }
        //MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoUrl];
        //UIImage  *thumbnail = [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame];
    }

    [self dismissModalViewControllerAnimated:YES];



      //[[picker parentViewController] dismissModalViewControllerAnimated: YES];


}

当用户录制视频并单击时,选择应用程序会崩溃,但从相机胶卷中选择时可以正常工作。

请帮忙!!

这是因为您可能会在关闭选择器后关闭视图:

[picker dismissModalViewControllerAnimated:YES];

[self dismissModalViewControllerAnimated:YES];

由于您使用了动画 YES,选择器尚未关闭,因此请使用新 API

[picker dismissViewControllerAnimated:YES completion:^{
        [self dismissModalViewControllerAnimated:YES];
    }];

该应用程序崩溃,因为在 iOS6[self dismissModalViewControllerAnimated:YES]; 中已弃用,您将其替换为[picker dismissViewControllerAnimated:YES completion:nil];可能会解决您的问题。
