Questions tagged [viewdidload]

Method in UIViewController class (Apple iOS SDK) for managing the view. Called after the controller’s view is loaded into memory.

This method is called regardless of whether the views were stored in a nib file or created programmatically in the loadView method. This method is most commonly used to perform additional initialization steps on views that are loaded from nib files. Available in iOS 2.0 and later.
