I included a Youtube video in my iOS 8.3 application using the standard inline url ( sample ) URL , which works as expected but looks pretty weird. This white gap (the blue area at the inspector of the view tree) should not be there.

I can confirm this not as a problem with CSS, as the inspector shows that it actually takes up 100% of the width and height of the uiWebView component.

I have installation restrictions in the left, top and right borders to align window / layout guides so that is not a problem. It seems that the private _UIWebViewScrollView component accepts the entire height assigned to the UIWebView and pushes the real content (UIWebViewBrowserView) to the bottom of the specified area.
