Edit Question
Title
Body
I thought there might be a way to easily hide and show a button in a row using auto layout so that views could be automatically arranged neatly depending on which are visible. For example, say I have two buttons that I always want centered in a frame: // pseudo visual format code: |-----[star][download]-----| When I press download I want now to see three buttons: ( pause is the download button relabelled; cancel is a previously hidden button) |--[star][cancel][pause ]--| I thought I could perhaps have all three buttons always present but perhaps override the width to make the view gracefully animate between states? I thought there might be a more semantic way to achieve the adding and removing of views from the auto layout structure. Any thoughts?
