iOS 8 Orientation change: Keyboard frame does not display correctly

Question

This is only an iOS 8 problem, the keyboard displays correctly in iOS 7 with device orientation change. My application supports both portrait and landscape orientation and u

Answer 1

Prior to iOS 8, the keyboard's location and width/height were always relative to portrait orientation when reported to the app. (e.g. Landscape's keyboard width is in the y direction, ~352 pixels on an iPad.) As of iOS 8, this has been updated to always have (0,0) at the top left of your (physical) view and the width/height reflect the x/y orientation you would normally expect outside of iOS. If you were previously positioning your keyboard via something like keyboardDidShow's [notification userInfo], you are going to get numbers that don't quite make sense. You can use something along these lines to take into account the pre-iOS8 idiosyncrasies:

- (void)keyboardDidShow: (NSNotification *) notification{

    NSDictionary *keyboardInfo = [notification userInfo];
    CGSize keyboardSize = [[keyboardInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    float height, width;
    if(UIInterfaceOrientationIsPortrait(orientation)){
        width = keyboardSize.width;
        height = keyboardSize.height;
    } else {
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1){
            width = keyboardSize.height;
            height = keyboardSize.width;
        } else {
            width = keyboardSize.width;
            height = keyboardSize.height;
        }
    }

    // Remainder of function
}

Which can be refactored down to...

- (void)keyboardDidShow: (NSNotification *) notification{

    NSDictionary *keyboardInfo = [notification userInfo];
    CGSize keyboardSize = [[keyboardInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    float width = keyboardSize.width;
    float height = keyboardSize.height;
    if(!UIInterfaceOrientationIsPortrait(orientation) && (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1)){
        width = keyboardSize.height;
        height = keyboardSize.width;
    }

    // Remainder of function
}

Also, the 8.1 update fixed several landscape/rotation bugs likely related to the above change. Grab the update and see if that solves your issue.
