title: dismissviewcontrolleranimated completion not calling completion on uiimagepickercontroller
body: <p>This is the code I have:</p>
  
  <pre><code>-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
  
  
      [picker dismissViewControllerAnimated:YES completion:^(void){
          NSLog(@"Test");
  
      }];
  }
  </code></pre>
  
  <p>It dismisses the modal view controller, but doesn't call the completion argument. Am i doing something wrong?</p>
