iOS –收到UILocalNotification后显示MFMessageComposeViewController

Question

I need to present a MFMessageComposeViewController after receiving a UILocalNotification .

Right now I have a view controller let's call it ViewControllerA which conforms to the MFMessageComposeViewControllerDelegate . In ViewControllerA I have setup the following method:

- (void)sendNow {

    MFMessageComposeViewController *mfMessageComposeVC = [[MFMessageComposeViewController alloc] init];

    if([MFMessageComposeViewController canSendText]) {

        DLog(@"Can send text");

        mfMessageComposeVC.recipients = self.numbers;
        mfMessageComposeVC.body = self.message;
        mfMessageComposeVC.messageComposeDelegate = self;
        [self presentModalViewController:mfMessageComposeVC animated:YES];
    }   
}

So when I receive a UILocalNotification from the AppDelegate I have setup the following method:

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {

    DLog(@"Notification Body: %@", notification.alertBody);
    DLog(@"%@", notification.userInfo);

    //application.applicationIconBadgeNumber = 0;

    UIApplicationState state = [application applicationState];
    if (state == UIApplicationStateInactive) {

        // Application was in the background when notification was delivered.

        ViewControllerA *vcA = [[ViewControllerA alloc] initWithNibName:nil bundle:nil];
        vcA.messageData = [NSArray arrayWithArray:self.messageData];    
        [vcA sendNow];

        //[remindersNavigationController pushViewController:reminderDetailsVC animated:NO];

    } else {

        // Application is currently running, Alert the user with a UIAlertView that he has scheduled a message to be sent at this time, give him the option of Close and Send
    }
}

The weird thing is that when running the app in the simulator it pops up a UIAlertView saying "this device cannot send text". This behaviour is expected. But when running it on the device it goes inside the IF and logs "Can send text" but the MFMessageComposeViewController is never presented. I know in fact that the MFMessageComposeViewController will present itself properly in the app without using the UILocalNotification .

Basically just after receiving the notification and clicking "View" I want the MFMessageComposeViewController to be presented.

    ViewControllerA *vcA = [[ViewControllerA alloc] initWithNibName:nil bundle:nil];
    vcA.messageData = [NSArray arrayWithArray:self.messageData];    
    [vcA sendNow];

vcA - is not added (pushed) to nav controller or window or to something else. Do you have a nav controller variable in app delegate? use it
