    text
    copied!<p>I encounter a strange behavior with a navigation controller and its root view controller in iOS 7. The goal is to use a sliding menu like MMDrawerController (<a href="http://github.com/mutualmobile/MMDrawerController/" rel="nofollow noreferrer">http://github.com/mutualmobile/MMDrawerController/</a>) or ECSlidingViewController (<a href="http://github.com/edgecase/ECSlidingViewController" rel="nofollow noreferrer">http://github.com/edgecase/ECSlidingViewController</a>).</p> <p>With both of them I got a bottom gap problem with my center main view (as seen on screenshots). In both case i'm using the "storyboard instantiateViewControllerWithIdentifier" to retrieve my controllers, so I think the problem comes from here.</p> <p>The navigation controller frame (center main view) is ok. But the root view controller of this navigation controller got a wrong frame height...</p> <p>Everything is fine in iOS6 and Xcode4, and the problem appears in iOS7 ans Xcode5. I already fixed the "extend edges" for all the app, only this navigation controller got this problem...</p> <p>After more investigations, it seems that the problem is that the height of the uitabbar is removed twice :</p> <p>1 - ECSlidingViewController remove the uitabbar height to calculate its own height</p> <p>2 - ECSlidingViewController load navigation controller as center main view with its frame</p> <p>3 - Navigation controller load its root view controller</p> <p>4 - Root view controller remove the uitabbar height again to calculate its height</p> <p>So the Root view controller get "window size - uitabbar height - uitabbar height". This is why there is a gap of the size of the uitabbar...</p> <p>Now I need to find out why such behavior, and how to get rid of it... Thanks in advance if you got any idea about this problem !</p> <p><img src="https://i.stack.imgur.com/hZdj0.jpg" alt="problem 1"> <img src="https://i.stack.imgur.com/CGWXF.jpg" alt="problem 2"></p>
