Adding banner to a completed game - ios

Question

I made a game(which already fills up the screen) but now I want to add a banner to it using admob.
If I add a banner now, part of the screen I am using will be blocked because of the banner. How do I insert the banner without overlaying my game scene?
PS: All sizes are based on my frame.size, So I tried
frame.size.height = 0.9 * frame.size.height
But this doesn't work(gives error)
What is the right way to do this?

Answer 1

You can't modify directly a view.frame or .bounds (and it's deprecated to do that).
To do that you'll have to create a pretty new frame :
gameView.frame = CGRectMake(CGRectGetMinX(gameView.bounds),
CGRectGetMinY(gameView.bounds),
CGRectGetWidth(gameView.bounds),
CGRectGetHeight(gameView.bounds) * 0.9f);

Answer 2

CGRect contentFrame = self.view.bounds;
if (contentFrame.size.width < contentFrame.size.height) {
_bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
} else {
_bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
}
CGRect bannerFrame = _bannerView.frame;
if (_bannerView.bannerLoaded) {
contentFrame.size.height -= _bannerView.frame.size.height;
bannerFrame.origin.y = contentFrame.size.height;
} else {
bannerFrame.origin.y = contentFrame.size.height;
}
[UIView animateWithDuration:animated ? 0.25 : 0.0 animations:^{
_contentView.frame = contentFrame;
[_contentView layoutIfNeeded];
_bannerView.frame = bannerFrame;
}];
Here content view is instance of UIViewController and _bannerView is GADBannerView instance.
