UI Designers, Get this Free iOS 8 Vector GUI Elements Kit
iOS 8 looks mostly similar to iOS 7, but there are enough interface changes to make it different, and there are actually many more subtle adjustments than most users may initially recognize. The developers and designers out there do notice that kind of thing though, and this excellent vector-based GUI element kit from the talented folks at Mercury should make those jobs a lot easier. Virtually the entire iOS 8 interface has been recreated as vector elements, which make contending with the variety of iOS screen sizes much easier.
