The company has long offered user interface guidelines, dating back to the original Macintosh, but has recently only offered its iOS 7 guidelines on the Developer Portal. By making them available to anyone via iBooks, the company appears to be looking to inform and inspire more designers.
An excerpt from the book:
Designing for iOS 7The iOS Human Interface Guidelines are a free download from iBooks.
iOS 7 embodies the following themes:
- Deference. The UI helps users understand and interact with the content, but never competes with it.
- Clarity. Text is legible at every size, icons are precise and lucid, adornments are subtle and appropriate, and a sharpened focus on functionality motivates the design.
- Depth. Visual layers and realistic motion impart vitality and heighten users’ delight and understanding.
Whether you’re redesigning an existing app or creating a new one, consider approaching the job in the way that Apple approached the redesign of the built-in apps:
- First, strip away the UI to expose the app’s core functionality and reaffirm its relevance.
- Next, use the themes of iOS 7 to inform the design of the UI and the user experience. Restore details and embellishments with care and never gratuitously.
- Throughout, be prepared to defy precedent, question assumptions, and let a focus on content and functionality motivate every design decision.
