WebView renders in the wrong location in my ScreenSaverView

Answer 1

I think the frame you're giving the WebView is in the wrong coordinates. Remember that a view's frame is expressed in terms of the superview's coordinate system (bounds).

You should be making the view as big as the superview's -bounds, if I get correctly what you want to do: usually a rect from (0,0) to (width,height).

Answer 2

I looked at your code and you're using the superview's (WebSaverView) frame rectangle as the WebView's frame. You should instead use it's bounding rectangle ([self bounds]). The bounding rectangle represents the area "inside" the superview. As you've seen, the two may not always have the same origin, which is causing this issue. You should not be adjusting the frame you're passed in initWithFrame:, since the origin probably has a very good reason for not being 0,0.
