iphone - UIImageWriteToSavedPhotosAlbum creates black thumbnail in camera roll -

I am saving the image in the camera roll using UIImageWriteToSavedPhotosAlbum, but always get a black thumbnail, even if the picture correct.

Do you have a signal to resolve this?

Thank you in advance for your help.

Regards,

I had the same problem in the image within the UIGraphics image contracts Drawing solves this issue:

  CGRact recessed = CGRactam (0,0,100,100); UIImage * image = ((Put your image here)); UIGraphicsBeginImageContext (rect.size); [Image drawinct: rect]; UIImage * Result = UIGraphicsGetImageFromCurrentImageContext (); UIGraphicsEndImageContext (); UIImageWriteToSavedPhotosAlbum (result, self, @selector (image: error saving didFinish: referenceinfo :), zero);
