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，选择的应用程序崩溃了，但从相机胶卷中选择时可以正常工作。
请帮忙!!

最佳答案
这是因为您可能是在关闭选择器之后就取消了 View :
[picker dismissModalViewControllerAnimated:YES];
[self dismissModalViewControllerAnimated:YES];
正如您使用动画YES一样，选择器尚未关闭，因此请使用新的API
[picker dismissViewControllerAnimated:YES completion:^{
[self dismissModalViewControllerAnimated:YES];
}];
