How to HIDE the iPad keyboard from a MODAL view controller?

Question

I'm trying to hide the iPad keyboard from a modal view controller but it doesn't work. I have tried resignFirstResponder but that doesn't have any affect if we are in a modal view controller. I tried resignFirstResponder in a non-modal UINavigationController with the very same UIViewController and the keyboard hides correctly.

Does anyone know how solve this problem?

Thanks.

[Update] it looks like there's something wrong with my code because the resignFirstResponder does work (I made a simple test case instead of using my code). But I still don't know what the problem is.

Answer 1

It was because I was using UIModalPresentationFormSheet. All of the other ones work as expected.... Wasted several hours on that.

Answer 2

I just confirmed the problem is indeed UIModalPresentationFormSheet and filed a bug report to apple rdar://8084017

Answer 3

Thanks for this comment, because even i wasted several days fixing this problem.

Answer 4

Thanks for your post... Dem waste mine 3 hours... When the apple gonna fixed it?

Answer 5

I am seeing the same problem with a textfield in a popover. The bottom right button to hide the keyboard doesn't work. Is there a way to code for that?

Answer 6

My workaround for this annoying bug:

[myTextField resignFirstResponder];
@try
{
    Class UIKeyboardImpl = NSClassFromString(@"UIKeyboardImpl");
    id activeInstance = [UIKeyboardImpl performSelector:@selector(activeInstance)];
    [activeInstance performSelector:@selector(dismissKeyboard)];
}
@catch (NSException *exception)
{
    NSLog(@"%@", exception);
}
