当用户录制视频然后点击选择时，我的应用会崩溃。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];
}
当用户录制视频并点击时，选择应用程序会崩溃，但从相机胶卷中选择时效果正常。
请帮助!!

答案 0 :(得分：0)
这是因为你可能在解雇拣货员之后解雇观点：
[picker dismissModalViewControllerAnimated:YES];
[self dismissModalViewControllerAnimated:YES];
因为您使用了动画YES，所以选择器尚未被解雇所以要么使用新的API
[picker dismissViewControllerAnimated:YES completion:^{
[self dismissModalViewControllerAnimated:YES];
}];
答案 1 :(得分：0)
应用程序崩溃，因为在iOS6中[self dismissModalViewControllerAnimated:YES];
不推荐使用[picker dismissViewControllerAnimated:YES completion:nil];替换它可能会解决您的问题。
