Guidelines for ios. How to start developing an application for ios?

Question

Mobile development

Hello!
I do some website and landing page design. Now there is a need to develop a sample application for the iPhone within a week.
Please tell me what to consider, where to read about current guidelines (it would be cool if it was in Russian).
What are the key points that must be taken into account when developing a prototype and design for a mobile application?
Thanks in advance for your replies and advice!
