SLComposeViewController Views is sent back to the application and becomes immune

I have a button in my application to open SLComposeViewControllerfor use with Twitter. When a presentation is presented, it animates correctly and disappears. I found that when it disappears, it goes in the opposite direction of the current view, and I have no way to return it. I tried manually sending all kinds of top down to the code with no luck. I feel that there is something fundamentally wrong with my application because this behavior is observed at any level for the navigation controller in the application. Below is a screenshot SLComposeViewController, which is the navigation bar in the application, I made the ViewController view with the Alpha value 0.0fto illustrate my point:

NSString *message = [NSString stringWithFormat:@"#%@", [twitterInfo objectForKey:@"hashtag"]];

if ([appDelegate isSocialAvailable]) {
    // code to tweet with SLComposeViewController
    SLComposeViewController *twitter = [[SLComposeViewController alloc] init];
    twitter = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
    [twitter setInitialText:[NSString stringWithFormat: @"%@", message]];
    [self presentViewController:twitter animated:YES completion:nil];        
}
