Questions tagged [autolayout]

Auto Layout is a constraint-based, descriptive user interface layout system for OS X and iOS.

The Auto Layout system defines layout constraints for user interface elements. Constraints represent relationships between user interface elements such as “these views line up head to tail,” or “this button should move with this split view subview.” When laying out the user interface, a constraint satisfaction system arranges the elements in a way that most closely meets the constraints. Constraints are objects and can be established in storyboards and XIBs, exposed as outlets, and created or modified in code.
