Position smart (dynamic) Admob banner to bottom of iOS screen? <p>I'm creating a smart (dynamic) Admob banner like this</p> <pre><code>bannerView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait origin:CGPointMake(0,0)]; </code></pre> <p>But how do I get it so a smart adMob banner is at the bottom of the screen? I need to know the height of the banner to be able to work out where at the bottom it's y coordinate should be, but I don't see how you do that if it's a smart (dynamically) sized banner?</p>
