Question

I want to put If condition on UIView. If the subView appears the button should be disabled. but i done know the syntax of how to put condition on UIView. I would be really thankful if any one can guide me. Thanks in advance.

Answer 1

If your view is appear means, your view is in view's hierarchy, that means, your view's window property will be not nil, you can check with this condition.

if (view.window != nil)
{
    //button disable 
}

Answer 2

i think you want your condition based on subview so you have to use subview property of view like this:

 if(yourView.subviews.count>0)

{

your code for disable button

}
