ios - iOS 8 中的相机显示黑屏

Question

此代码用于从相机一张一张地捕获图像，但是在下次拍摄一张图像后相机将打开但黑屏(像它一样，快门关闭)。所有其他 ios 版本都可以工作，但在 ios 8 中不起作用.请告诉我如何解决？

-(void)openCamera
 {
   if(![PickerHandler doesDeviceSupportMediaType:ITEM_TYPE_PHOTO])
   {
    [PickerHandler showNoDeviceSupportWarningForMediaType:ITEM_TYPE_PHOTO withDelegate:self];
   }
   else 
   {
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;

    picker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeImage];
    [self presentViewController:picker animated:YES completion:nil];
   }

 }

转到设置>隐私>图片 ...并检查您的应用是否有权限。

在代码中，使用它来验证摄像头访问权限。

- (BOOL)authorizedCameraAccess
{
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    return  (status == AVAuthorizationStatusAuthorized);
}
