WebView

Constraints set

Answer 1

Set UIWebView background colour to clear. I guess it will help you.

Answer 2

Uncheck Adjust Scroll View Insets from Attributes inspector by selecting view controller.

Answer 3

OK I fix issue by drag top edge of WebView to top of view controller. Now it work with no problem!

Answer 4

If you can't drag WebView to the top of your ViewController -- when you have an extra UI on top of the WebView -- then put a Container View instead and move web view inside it. It will loose the connection to Navigation Controller and will stop drawing that grey placeholder.
