Hi all, I know I'm sounding noobish now.. But.. How does these constraints work ? Lets say I have an 'header' view. I want this header view stay the same height as it is. So I add the constraint to "Pin" the height. Now I want to to be as width as the self.view.. So I rightlcick my 'header' to 'view' and say equal width. Doing the same for leading space, and top space. So now I have set constraints for top, left, width and height. Left and Top of 'header' is 0. I have a preview of 4.5" 5" and iPad, on the iPad I see that there is space between the left and my header, 20 ? or little less, but more than default -16 Can anyone help me out, if someone understands what I'm talking about ?
