如何以编程方式将App引入前景

Question

I develop some LocalNotifications for my iOS8-App using UIMutableUserNotificationAction

In case of the App is running in background and the user touches at this UIMutableUserNotificationAction the app should be comeback to foreground.

How can i solve that ?

The event that UIMutableUserNotificationAction fires is:

-(void)application:(UIApplication *)application handleActionWithIdentifier:(NSString 
*)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler

You should instantiate your storyboard and view controllers in application:handleWithIdentifier.. and push the view controller to the navigation controller if you have one or set as the root view controller if you don't have one.

You can also use application:didReceiveLocalNotification: method.

Something like this:

    - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
    {
            MyViewController *presenterVC = [_storyBoard instantiateViewControllerWithIdentifier:@"MyViewController"];

            [_navigationController pushViewController:presenterVC animated:NO];    

            self.window.rootViewController = _navigationController;

    }
