Remarks
This method is a re-entry point for user activities (e.g., Handoff activities). 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>
A client app initiates a Handoff-related user activity by calling, for instance, UpdateUserActivity(String, NSDictionary, NSUrl) with a matching userActivityType. This WillContinueUserActivity(UIApplication, String) method begins the Handoff-related re-entry to the app.
App devs should override this method to return a Boolean indicating whether or not the app is capable of completing the user activity. If this method returns true, the system will shortly call the method M:UIKit.UIApplication.ContinueUserActivity*.
