iOS - Make only subview clickable

Question

I am trying to make a custom dialog view. I have come pretty far, however there is one issue. When my dialog has popped up, I can press on textfields behind it. How can I make sure that the user can only click on the subview that is the dialog view when it is present?

Answer 1

Simple solution: when you show dialog create view

 CGRect viewBackFrame =  (CGRect){
        .origin = CGPointZero,
        .size = parentView.frame.size
    };
 UIView* viewBack = [[UIView alloc] initWithFrame:viewBackFrame];
 viewBack.backgroundColor = [UIColor clearColor];
 [parent insertSubview:viewBack belowSubview:dialog];

Answer 2

UIView has a property called exclusiveTouch that is supposed to do what you are trying to achieve. Setting your dialog's exclusiveTouch property to YES should do the trick.
