title: What is tint in Xcode?
body: <p>Really basic question that I can't find the answer to. What is tint in Xcode and why is the default tint for all views blue? What does it affect? I've noticed that colors of some images within these views don't look quite right unless I set the tint to white and it's really annoying to have to set every new view's tint to white just because I don't understand what it does.</p>
