Hello everyone. Ive been developing apps for ios devices (ipads, iphones, ipods) and I have a problem regarding UIViews width. I want a child UIView to have the same width as its parent, but unable to figure out how to do it. I am using Auto Layout on my screens setting the necessary constraints, but this only keeps organized my widgets on screen (doesnt auto resize anything for different screen sizes on iphone). Can someone help me achieve this? I need UIView same width as its parent.
