IOS UIScrollview not allowing keyboard to close when screen touched - ios

Question

I built an app that when a textview was filled in, the keyboard would pop up and allow you to type. If I decided that I didn't want the keyboard up, I could tap the background view controller and it would fall away. Now, I added a scrollview. Everything works fine, but I cannot get the actions to connect and make the keyboard fall away when touching outside the textview.
(I cannot make a custom view controller in Xcode)
Does anyone have any fixes?
Thank you in advance!

theField.text = array [i];

Try UITapGestureRecognizer:
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapScrollView:)];
[scrollView addGestureRecognizer:singleTap];
and for the action:
- (void)tapScrollView:(UITapGestureRecognizer *)gesture {
[self.actionField resignFirstResponder];
[self.impactField resignFirstResponder];
[self.resultField resignFirstResponder];
}
