In the designer I added a Scrollview, I made it have a scrollbar with this code:
svDetails.contentSize = CGSizeMake(360, 400);
However I want it to be 100% of the phone width. (leave the width unchanged).
Because right now it fits perfectly on iPhone 4s,5 and 5s but doesn't look quite right on the iPhone 6,6+ (scrollview is to small)
