UPDATE This answer is no longer accurate. See the correct answer.

If your UITextField is in a modal page sheet view (UIModalPresentationFormSheet), then there is (currently) no way to force the device to dismiss the keyboard this devforums post from an apple engineer.

回答2:

In iOS 4.3, Apple introduced the above mentioned method, disablesAutomaticKeyboardDismissal. It returns YES for UIModalPresentationFormSheet, preventing the keyboard from dismissing.

Overriding this method works, but if you present your view controller inside a UINavigationController, you must subclass UINavigationController and override the method there.

I've confirmed that this does indeed work on iOS 6. Just make sure to pay attention to the UINavigationController clause.

Now we can

- (BOOL)disablesAutomaticKeyboardDismissal {
    return NO;
}
