Why is UIScrollView leaving space on top and does

Question

I am new to objective-C programming.

I am using UIScrollView with some labels, image and text view on it.

I have turned off Autolayout and already tried with "Adjust scroll View Insets" on (situation described in title) and off (doesn't scroll).

This is what I insert into viewDidLoad:

    [scroller setScrollEnabled:YES];
[scroller setContentSize:CGSizeMake(320, 687)];

But I must be missing something very simple.

iOS 11

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

Answer 2

Actually, the margin has nothing to do with ScrollViewInsets or contentOffset. It's just a conflict between SuperView.Top and SafeArea.Top pinning, happens when you pin the UIScrollView to top, bottom, left and right.

This is the right way to cover the top margin.

1) Pin all the four sides.

2) Select the top constraint > Change Second Item to Superview.Top

3) Then the last step is to change the Constant to 0 (Zero).

In my case only changing this UIScrollView Content Insets property in IB from Automatic to Never helped.

In your view .m file, use this code to fix this problem

-(void)layoutSubviews{
    // To fix iOS8 bug of scrollView autolayout
    if([[[[[UIDevice currentDevice]systemVersion] componentsSeparatedByString:@"."]objectAtIndex:0] integerValue] == 8){
        [self.tableView setContentInset:UIEdgeInsetsMake(0, 0, 0, 0)];
    }
}
