相机在ios 8中显示黑屏 [英] Camera show black screen in ios 8

问题描述

此代码用于从相机中逐个捕获图像，但在下次拍摄一张图像后，相机将打开但黑屏（如同，快门关闭）。所有其他ios版本的工作，但不适用于ios 8 。请告诉我如何解决？

   }
   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];
   }

 }

推荐答案

转到设置>隐私权>图片 ...并检查您的应用是否有权限。

Go to Settings > Privacy > Pictures ... and check if your app have permission.

在代码中，使用此功能验证相机访问。

In the code, use this to verify camera access.

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