In this article I will share some useful resources for iOS application and game design beginners. First things first though -- to understand the main interface, you should read this link -- IOS Human Interface Guidelines. It's a long read, but it's worth your time as it will answer most of your beginner questions in designing for iOS. With it, you will be able to understand Apple design principles. It also expounds on how the following play important roles in the design process:
Deference. The UI helps people 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
people’s delight and understanding.
Another amazing read is Ben’s Taylor Guide to IOS Design. This article summarizes how human interaction plays a role in becoming an interface guideline when it comes to designing for iOS.
After you have gone through the reads mentioned above, you may want to grab these cheat sheets for starting and setting up your design station:
