UIApplicationDelegate.OnResignActivation(UIApplication) Method

Definition

Called when the application is about to enter the background, be suspended, or when the user receives an interruption such as a phone call or text.

[Foundation.Export("applicationWillResignActive:")]
public virtual void OnResignActivation (UIKit.UIApplication application);
abstract member OnResignActivation : UIKit.UIApplication -> unit
override this.OnResignActivation : UIKit.UIApplication -> unit

Parameters

application
UIApplication

Reference to the UIApplication that invoked this delegate method.

Attributes

Remarks

Because iOS applications should be designed to be long-lived, with many transitions between foreground processing, suspension or background processing, or interrupted, this method may be a good place to release expensive resources or otherwise ensure that the application is in a consistent, restorable state.
