- Method to invoke when the notification is posted.
The returned NSObject represents the registered notification. Either call Dispose on the object to stop receiving notifications, or pass it to MonoTouch.Foundation.NSNotificationCenter.RemoveObserver
The following example shows how you can use this method in your code
c# Example
// // Lambda style // // listening notification = UIApplication.Notifications.ObserveContentSizeCategoryChanged ((sender, args) => { /* Access strongly typed args */ Console.WriteLine ("Notification: {0}", args.Notification); Console.WriteLine ("WeakNewValue", args.WeakNewValue); }); // To stop listening: notification.Dispose (); // //Method style // NSObject notification; void Callback (object sender, MonoTouch.UIKit.UIContentSizeCategoryChangedEventArgs args) { // Access strongly typed args Console.WriteLine ("Notification: {0}", args.Notification); Console.WriteLine ("WeakNewValue", args.WeakNewValue); } void Setup () { notification = UIApplication.Notifications.ObserveContentSizeCategoryChanged (Callback); } void Teardown () { notification.Dispose (); }
