iOS Human Interface Guidelines

Adaptivity and Layout

People generally want to be able to use their favorite apps on all of their devices and in any context. In iOS, interface elements and layouts can be configured to automatically change shape and size on different devices, during multitasking on iPad, in split view, when the screen is rotated, and more. It’s essential that you design an adaptable interface that provides a great experience in any environment.

Device Screen Sizes and Orientations

iOS devices come in a variety of screen sizes and can be used in either portrait or landscape orientation.

Auto Layout

Auto Layout is a development tool for constructing adaptive interfaces. Using Auto Layout, you can define rules (known as constraints) that govern the content in your app. For example, you can constrain a button so it’s always horizontally centered and positioned eight points below an image, regardless of the available screen space.
