ios - Why is UIScrollView leaving space on top and does not scroll to the bottom

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.

Answer 1

1... Why is UIScrollView leaving space on top

With Storyboard- Goto view controller > Attribute Inspector > Uncheck Adjust Scroll View Insets property

With Code- For extra space set viewController property automaticallyAdjustsScrollViewInsets to NO, by default it is YES.

self.automaticallyAdjustsScrollViewInsets = false; 
scroller.contentInset = UIEdgeInsetsZero;
scroller.scrollIndicatorInsets = UIEdgeInsetsZero;
scroller.contentOffset = CGPointMake(0.0, 0.0);

2... does not scroll to the bottom

To make it scroll try with large number in contentSize like CGSizeMake(320, 1687). If it works that means you are not setting the contentSize large enough to have all its content.
