Keyboard autocorrection height (with/without the autocorrection)

问题

I get the keyboard height like this:

- (void)keyboardNotification:(NSNotification*)notification
{
    NSDictionary* keyboardInfo = [notification userInfo];
    NSValue* keyboardFrameBegin = [keyboardInfo valueForKey:UIKeyboardFrameEndUserInfoKey];
    CGRect keyboardFrameBeginRect = [keyboardFrameBegin CGRectValue];
}

Now, I have the keyboard height. But without the autocorrection height:

If the UITextAutocorrectionType is YES / NO the keyboard height stay the same.

How can I get the Keyboard autocorrection height?

Thanks in advance.

回答1:

Use this :

 CGRect keyboardBounds;
        [[notification.userInfo valueForKey:UIKeyboardFrameEndUserInfoKey] getValue: &keyboardBounds];
   // Need to translate the bounds to account for rotation.
  keyboardBounds = [self.view convertRect:keyboardBounds toView:nil];

回答2:

Use UIKeyboardWillChangeFrameNotification. This will be called every time when suggestion bar shows or hides.

NSConcreteNotification 0xc472900 {name = UIKeyboardWillChangeFrameNotification; userInfo = {
    UIKeyboardAnimationCurveUserInfoKey = 7;
    UIKeyboardAnimationDurationUserInfoKey = "0.25";
    UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 216}}";
    UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 588}";
    UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 372}";
    UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 480}, {320, 216}}";
    UIKeyboardFrameChangedByUserInteraction = 0;
    UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 264}, {320, 216}}";
}}
