iOS ScrollView setContentSize not Working

I am using Xcode 8, iOS 10. I have Create ScrollView from Storyboard. My Flow is

  • viewDidLoad method have Restcall, Which fetch Information from Server.
  • On Return, I parsed Response and based on that Create UIElements in Method and then add to one ParentView.
  • At last ParentView will be added to ScrollView.
[self.scrollView addSubview:parentView];
self.scrollView.frame = CGRectMake(0, 0, 320, parentView.frame.size.height);
[self.scrollView setContentSize:CGSizeMake(320, parentView.frame.size.height)];

When I print Scrollview height after this code, it shows "680" which is more than My View Height. I have tried with "viewDidLayoutSubviews" Method but still the ScrollView is not working. Does anyone have any idea why It is not scrolling?

Solution

  • The problem in your code is that you are setting the scrollview height and contentSize height from parent view.

    You should do as following :-

    [self.scrollView addSubview:parentView];

self.scrollView.frame = CGRectMake(0, 0, 320, [UIScreen mainScreen].bounds.size.height);

[self.scrollView setContentSize:CGSizeMake(320, parentView.frame.size.height)];

    Hope this will be helpfull
