why UIScrollView is leaving space from top in ios 6 and ios 7
In Xcode 5, in storyboard select your controller > in Attribute Inspector disable Adjust Scroll View InsetsAlso check if you have set any contentInset
Edit : I attached a pic
The fix is to implement the following line of code after in the viewDidLoad;
self.automaticallyAdjustsScrollViewInsets = NO;
Update for iOS 11
if #available(iOS 11.0, *) { scrollView.contentInsetAdjustmentBehavior = .never} else { automaticallyAdjustsScrollViewInsets = false}
