图像未从图库中选择

Question

 -(void)Open_Library
    {
   // Create image picker controller
   UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

   // Set source to the camera
    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    imagePicker.delegate=self;
   // Delegate is self

    // Allow editing of image ?
    imagePicker.allowsEditing = YES;
   // Show image picker
   if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
       {

        popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];

      CGRect popoverRect = CGRectMake(10, 10, 200, 200);
      [popover presentPopoverFromRect:popoverRect inView:self.imgview permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

  }
  else
  {
       [self presentViewController:imagePicker animated:YES completion:nil];
 }

}


 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:  (UIImage *)img editingInfo:(NSDictionary *)editingInfo
  {
_imgview.image = img;
[picker dismissModalViewControllerAnimated:YES];
}

此处图片在图库中打开但未选择。这里的“imgview”是用于显示从图库中选择的图像的IMAGEVIEW。我在这里做错了什么。我想显示从画廊中选择的图像。
