Keyboard not showing after MFMessageComposeViewController

Question

In the iPhone app, I have a button UITextViewand a button that allows the user to send content UITextViewas a text message. The code is as follows:

MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.messageComposeDelegate = self;

picker.body = textView.text;

[self presentModalViewController:picker animated:YES];

Everything works fine, except when the message has been sent or Canceled to MFMessageComposer: The keypad for is UITextViewno longer displayed, even if the cursor is blinking .

I tried several things, including [textView resignFirstRepsonder]buttons and buttons in the code -viewDidDisappear. [textView becomeFirstResponder]in the method MFMessageComposeViewControllerDelegateor -viewDidAppearnothing has changed ...

Any ideas?

iOS 5, . MFMessageComposeViewController, UITextView:

[self presentViewController:messageComposer animated:YES completion:NULL];
[textView resignFirstResponder];

Then in the delegate method messageComposeViewController:didFinishWithResult:do the following:

[controller dismissViewControllerAnimated:YES completion:^{
  [textView performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0];
}];

This fixed the keyboard extinction issue for me. Without the need to constantly close the keyboard.

This behavior will not be displayed if the viewController, which is displayed before the modal VC, is a child of the navigation controller. So the solution is to create a fake UINavigationController and add a VC controller to the navigation controller.
