为什么imagepicker说没有视频

Question

我的ipod中有视频，但是imagepicker说没有视频，如果有人可以破解它不理解它

UIImagePickerController *videopicker = [[UIImagePickerController alloc]init];
videopicker.delegate = self;
videopicker.mediaTypes =
[[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
videopicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController:videopicker animated:YES];
videopicker.wantsFullScreenLayout = YES;

Answer 1

以下代码对我来说很好，它同时显示照片和视频

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum]) {

            UIImagePickerController *apicker = [[UIImagePickerController alloc] init];
            apicker.delegate = self;
            apicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
            **apicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeSavedPhotosAlbum];**
            [self presentModalViewController:apicker animated:YES];
        }
    }
