How to prevent user to select and swap images at a same time from image library so that it doesn't to go edit view?

I am having a problem regarding selecting image from image library in iPhone(iOS 8.4). Here is my code: UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; imagePicker.allowsEditing = NO; imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; [self presentModalViewController:imagePicker animated:YES]; But if I select an image and swap that image at the same time it opens an edit view and then if I try to delete that image, my app crash. Is it a default feature of image library? Or can it be handled by code? Please let me know. Thanks in advance
