[ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 6, 0, ObjCRuntime.PlatformArchitecture.All, null)]
public virtual bool ShouldSaveApplicationState (UIKit.UIApplication application, Foundation.NSCoder coder);

abstract member ShouldSaveApplicationState : UIKit.UIApplication * Foundation.NSCoder -> bool
override this.ShouldSaveApplicationState : UIKit.UIApplication * Foundation.NSCoder -> bool

備註

此方法和 ShouldRestoreApplicationState(UIApplication, NSCoder) 都必須傳回 true 狀態保留和還原才能發生。 這些方法方便測試狀態保留程式的各個層面。
