> but UIKit doesn't even have a standard button class
Doesn't anyone else use UIButton? Granted, the native iOS app I developed was intended primarily for blind people, so I didn't really make it visually polished.
Yes, the visual polish is what I mean. It's not rocket science to style UIButton, but the lack of a good default style means that mediocre native apps often have weird/inconsistent highlighted button states, and so on.
