Just hiding views won't help, as it still will take place. You have several options: 1. Each of views inside scrollView should have height constraint that should be set to 0 when hiding is required. Then you should call

[scrollView setNeedsLayout];
[scrollView layoutIfNeeded];
  1. You can remove unneeded views from scrollView by calling

[viewToHide removeFromSuperview];
