orientations

Objective C apps can handle different screen sizes and orientations by utilizing auto layout and size classes. Auto layout allows developers to create dynamic and adaptive user interfaces that adjust to different screen sizes and orientations. Size classes provide a way to define different layouts for different screen sizes, and auto layout constraints can be used to specify how the views should be arranged. By using size classes and auto layout, Objective C apps can easily adapt to various screen sizes and orientations without the need for hardcoded layouts for each device.
