Mock up iOS 7 screens in Photoshop with this file
User experience (UX) design studio Teehan+Lax is offering a free downloadable Photoshop file containing interface elements from the first beta release of iOS 7. You can grab the iOS7 GUI PSD file by visiting their Web site.
Teehan+Lax said that the file is being offered "to help you pitch, design and build amazing software." It's suitable for using with mockups that you're creating, but the company asks that people interested in making software or their own Photoshop files that work similarly to recreate their own interface elements independently.
