you alter order of operations bit.
select image photo library -> scale image -> save scaled image documents directory -> show scaled image in uiimageview.
scaling , saving image takes time, user have bit of wait before see image in uiimageview. displaying activity indicator cancel alternative idea.
i've used technique pretty big images , worked on older devices without incurring memory warnings.
