why UIScrollView is leaving space from top in ios

Question

I have turned off Autolayout and viewcontroller is embedded in navigation controller. I am using Xcode 5, Storyboard.

I don't understand why is it leaving space from top. Actually in storyboard i have put my label exactly below navigation bar. But when i run it on simulator then it leaves space from top.

One of the hacky way to resolve this

-(void)viewWillLayoutSubviews
{
   self.scrollViewMain.frame = CGRectMake(0, -70, 320, 800);

   self.scrollViewMain.contentSize = CGSizeMake(320, 800);
}

But am i missing something very simple approach.

Answer 1

Update for iOS 11

if #available(iOS 11.0, *) {
    scrollView.contentInsetAdjustmentBehavior = .never
} else {
    automaticallyAdjustsScrollViewInsets = false
}

Answer 2

The fix is to implement the following line of code after in the viewDidLoad;

self.automaticallyAdjustsScrollViewInsets = NO;

Answer 3

In Xcode 5, in storyboard select your controller > in Attribute Inspector disable Adjust Scroll View Insets Also check if you have set any contentInset

Edit : I attached a pic

Answer 4

Go to main storyboard. Select view controller, see property "Adjust Scroll view Insects" in attribute inspector. if you do not want top spacing.then uncheck "Under Top Bars". if you don not want bottom spacing.then uncheck "Under Bottom Bars". this kind of problem come when we use scroll view related controllers.

This is a feature for navigation and tab bar to adjust content in scroll view like controls.

Answer 5

Inspector: Select scrollView and set up Content Insets - never

Answer 6

For me in xcode 7 and Swift 2.x I was populating a UIScrollView with a for loop and had to set the contentInset to zero.

for image in images {
  self.scrollView.contentInset = UIEdgeInsetsZero
}
