Try doing the load in -viewWillAppear: instead. My guess is that the WKWebView is adding a UIScrollView when you load the content, and that scroll view is being modified after the fact when you can see it.
Alternatively you can try setting automaticallyAdjustsScrollViewInsets=NO on your view controller. > On Oct 29, 2015, at 6:14 PM, Rick Mann <rm...@latencyzero.com> wrote: > > I have a tab bar application with a nav controller in each of the tabs. > Clicking on an item in that pushes a new view controller with a WKWebView. > Actually there's a UIView specified in IB, and in -loadView I create the > WKWebView and add it to the UIView, and then add constraints to make it be > the same size. > > Then in -viewDidAppear:, I load the web view content.
