Graphic issue presenting MFMessageComposeViewController

Question

I've this strange issue when i'm presenting a MFMessageComposeViewController in my app!

I don't know what this black bar is and i'm unable to remove the app logo from the NavigationBar.

And here is the code for presenting the controller

MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc] init];
[[messageController navigationBar] setBarTintColor:SMAN_ORANGE_COLOR];
[[messageController navigationBar] setTintColor:[UIColor whiteColor]];
messageController.messageComposeDelegate = self;
[messageController setRecipients:recipents];
[messageController setBody:message];

// Present message view controller on screen
[self presentViewController:messageController animated:YES completion:nil];

Answer 1

I solve the issue subclassing my UINavigationController and changing the appearance of it with [UINavigationBar appearanceWhenContainedIn:[myNavControllerSubclass class], nil]
