iOS Interface Design
iOS Interface design checklist
!important Always keep your interface designs as subtle accents as not to overpower the content users seek.
Buttons:
A minimum tappable button size is a suggested 44x44 points according to apple developer IOS guides.
Avoid
1. CSS fixed positioning in iOS. Content does not move off screen when users zoom or pan the page
2. Don't rely on pointer based interactions.
Visual Metaphors
Always use standard and consistent interface elements. Metaphors must be slight and never overstated. A great example is a folder which is also a real world object.
