PresentViewController From AppDelegate handleActionWithIdentifier

Is it possible to present a view controller from the AppDelegate method handleActionWithIdentifier?

I am registering action categories similar to below:

action1 = [[UIMutableUserNotificationAction alloc] init];
[action1 setActivationMode:UIUserNotificationActivationModeBackground];
[action1 setTitle:@"Tweet"];
[action1 setIdentifier:NotificationActionOneIdent];
[action1 setDestructive:NO];
[action1 setAuthenticationRequired:NO];

When my remote notification arrives I can pull down or swipe left on the home screen to see the text "Tweet"

My handleActionWithIdentifier method is very simple:

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler {

    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
    {
        SLComposeViewController *tweetSheet = [SLComposeViewController
                                               composeViewControllerForServiceType:SLServiceTypeTwitter];
        [tweetSheet setInitialText:@"Tweeting this is awesome!"];
        [self.window.rootViewController presentViewController:tweetSheet animated:YES completion:^{}];
    }

    if (completionHandler) {

        completionHandler();
    }
}

However when I click the "Tweet" action category from my notification it does nothing. It doesn't bring up the Twitter tweet now window.

I don't want the app to have to open in order to have this action occur. Thoughts?

The AppDelegate action handlers are only meant to perform background operations, only launching the app for short amount of time, performing the block on a background thread then backgrounding the app again. Be sure to read the apple documentation : https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/#//apple_ref/occ/intfm/UIApplicationDelegate/application:handleActionWithIdentifier:forRemoteNotification:completionHandler:

For your example instead of presenting the tweet view controller you'll need to directly send the tweet without user interaction.

Try this

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler {

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{
    SLComposeViewController *tweetSheet = [SLComposeViewController
                                           composeViewControllerForServiceType:SLServiceTypeTwitter];
    [tweetSheet setInitialText:@"Tweeting this is awesome!"];
    [self.window makeKeyAndVisible];
    [self.window.rootViewController presentViewController:tweetSheet animated:YES completion:^{}];
}

if (completionHandler) {

    completionHandler();
}

}

Just try with this:

self.window.rootViewController = tweetSheet;
