[Foundation.Export("application:continueUserActivity:restorationHandler:")]
[ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 8, 0, ObjCRuntime.PlatformArchitecture.All, null)]
public virtual bool ContinueUserActivity (UIKit.UIApplication application, Foundation.NSUserActivity userActivity, UIKit.UIApplicationRestorationHandler completionHandler);
abstract member ContinueUserActivity : UIKit.UIApplication * Foundation.NSUserActivity * UIKit.UIApplicationRestorationHandler -> bool
override this.ContinueUserActivity : UIKit.UIApplication * Foundation.NSUserActivity * UIKit.UIApplicationRestorationHandler -> bool
Parameters
- application
- UIApplication
The UIApplication singleton.
- userActivity
- NSUserActivity
The user activity identifier.
- completionHandler
- UIApplicationRestorationHandler
System-provided callback that can be called with appropriate UIResponder or UIDocument objects.
Returns
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.
