Question

Any clues why my programmatically defined UIScrollView (using the application frame) always leaves an empty space at the top (below the navigationBar) of 20 pixels. How can I close that?

UIScrollView *vScrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
vScrollView.backgroundColor = [UIColor redColor];

My screen looks like this:

• status bar
• — Navigation bar
• — the mysterious gap (10px?)
• —- my Scrollviewcontent (with red background color)

How do I need to call the application frame size to avoid that gap?

Answer 1

I found I use the wrong frame coordinates “applicationFrame”. All works fine when changing it to the bounds.

UIScrollView *vScrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
