- application
- UIApplication
The UIApplication singleton.

true if the app handled the user activity.
- Attributes
Remarks
The system calls this method if the application has registered its ability to handle the userActivity and WillContinueUserActivity(UIApplication, String) has returned true.
An application indicates interest in a particular userActivityType by adding the value to it's info.plist as a T:System.String value in an array called NSUserActivityType. By convention, the activity type begins with a domain-reversed string identifying the developer:
<key>NSUserActivityTypes</key>
<array>
<string>com.xamarin.HandOffDemo.verb</string>
</array>
The completionHandler is a system-provided function that takes an array of UIResponder objects that should have an opportunity to handle the userActivity. The system will call the RestoreUserActivityState(NSUserActivity) method on each of these objects.
