Free iOS 7 Illustrator Vector UI Kit for iPhone and iPad
Mercury released an Illustrator file of vector-based iPhone UI elements. It originally created this resource because Mercury found themselves needing a place to quickly grab vector versions of iPhone buttons, bars, and stock elements when creating our designs.
Mercury has continued to create internal UI resources but haven’t slowed down long enough to share an updated UI file until now. Though the majority of the items in the document are based on iPhone, this file includes a few iPad specific items as well. Mercury decided not to break iPhone and iPad apart since there is so much redundancy. It seemed best to keep everything conveniently located within a single file. It is also expect that the separation between iPhone and iPad will continue to soften over time.
