Circle crop image

Can i add something so the user can crop a circle image instead beacuse the image I'm displaying on profile is a circle?

´´´

  • (void)showPhotoLibary { if (([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO)) { return; }

    UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

// Displays saved pictures from the Camera Roll album.
mediaUI.mediaTypes = @[(NSString*)kUTTypeImage];

// Hides the controls for moving & scaling pictures
mediaUI.allowsEditing = YES;

mediaUI.delegate = self;

//  [self.navigationController presentModalViewController: mediaUI animated: YES];

[self presentViewController:mediaUI animated:YES completion:nil];

    }

I would probably look into masking the image with a circle (which you may already be doing for the profile), or creating a circle to move around the image, whereby once the circle is placed, the coordinates for the center of the circle could be used in relation to the original image.
