UIScrollView doesn't scroll after upgrading to iOS7 / xcode 5

Question

I have an app which in xcode 4.5 and ios 6.1 worked perfectly fine when scrolling. However, after downloading xcode 5 and iOS 7 my scroll views does not work anymore.???

Answer 1

I didn't have a fixed height so I set the contentsize of the scrollview in code according to my label inside the scrollview

CGSize scrollViewContentSize = CGSizeMake(320, myLabel.frame.size.height);
[self.scrollView setContentSize:scrollViewContentSize];

Answer 2

I just set "Vertical Space" to auto constant value. May be it help in some case.

and set it in Attributes inspector

I hope it help. Thx.

Answer 3

I'm not sure if this is going to work

- (void) viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [grillretterScroller setContentSize:CGSizeMake(self.view.bounds.size.width, 915)];
}

Answer 4

I had the same issue after developing an app for iOS8, then testing on iOS7 afterwards. Although I had tried setting certain options on the scroll view such as:

[self.scrollView setScrollEnabled:YES];
[self.scrollView setContentSize:CGSizeMake(self.view.frame.size.width, 700)];
[self.scrollView setContentOffset:CGPointZero];

The solution that worked for me was to go into the storyboard file, and ensure that you have constraints set for all views within the scroll view. The scroll view's content size is calculated by the constraints of each subview within the scroll view, so in my case, I had a UIView and UITableView. After setting constraints for UIView (top, leading, trailing, height), and UITableView (vertical spacing to UIView, leading, trailing, bottom), the scroll view calculated the content size and started to function.

While turning off Auto Layout does work, it's not an ideal solution for everyone. Just play around with Storyboard and set constraints for all subviews in the scroll view, so that a vertical line of constraints are set, from the top of the scroll view to the bottom.

I solved this by deselecting 'Use Autolayout' in the File Inspector pane of main view within the Scroll View.

If you want to keep 'Autolayout' enabled, try 'Editor -> Reslove Autolayout Issues -> Add Missing Constraints'. The key constraint appears to be 'Bottom Space to: Superview and in my case was -300, giving 300 scroll space on the botton of the view.

Answer 6

As mentioned by user2394787:

Select your view controller that has the scrollview then go to

Editor -> Resolve AutoLayout Issues -> Add Missing Contraints in [your view controller].  

This will make it work.
