SWIFT: in uiscrollview can't press button

Question

I use uiscrollview and when I click button in scrollview I add text in textView and then button outside view so... when button outside view I scroll down and can't click the button. My code:

change scrollView height:

scrollView.contentSize = CGSizeMake(self.view.frame.size.width, 1000);

Answer 1

You could try setting the delaysContentTouches to false on your UIScrollView.

UIScrollView

Answer 2

In my case, when button is into a subview -> into a ScrollView, the tap will not be cached, non matter what scroll view settings you have..

So I added the button as subview of my scrollView and tap was fired

scrollView.addSubview(button)

Answer 3

CGRect frameforMainView = mainView.frame;
frameforMainView.size.height = viewFirstAnswerButton.frame.origin.y + viewFirstAnswerButton.frame.size.height;
mainView.frame = frameforMainView;

//Now Set ContentSize Of scroll view;
[scrollView setContentSize:CGSizeMake(0, mainView.frame.origin.y + mainView.frame.size.height)];

if you are using Autolayouts then don't forget to add translatesAutoresizingMaskIntoConstraints = YES

Answer 4

Drag all subviews from mainView to ScrollView. And hide the mainView. Make sure mainView(ContainerView of scrollView) should also be a subView of scrollView.
