Preventing multiple buttons from being touched at the same time

Question

In iOS is there anyway to prevent a UIView containing multiple buttons (siblings) from being simultaneously from being touched? For instance, two non-overlapping buttons that ar

Answer 1

You need to find all buttons on that view and set the "exclusiveTouch" property to true in order to prevent multi touch at the same time.

func exclusiveTouchForButtons(view: UIView) {
    for cmp in view.subviews {
        if let cmpButton = cmp as? UIButton {
            cmpButton.exclusiveTouch = true
        } else {
            exclusiveTouchForButtons(cmp)
        }
    }
}

Answer 2

I have tried both  multiTouchEnabled and exclusiveTouch but unfortunately 
none of them workout for me.I have tried the following code worked 
perfectly.

Set this code at .h file

BOOL ClickedBool;

Set the following code at method start.

if(ClickedBool==TRUE)
{
     return;
}
else
{
    ClickedBool=TRUE;
}

Answer 3

for(UIView* v in self.view.subviews)
    {
    if([v isKindOfClass:[UIButton class]])
    {
        UIButton* btn = (UIButton*)v;
        [yourButton setExclusiveTouch:YES];
    }
}

Answer 4

Set UIView.exclusiveTouch.

Answer 5

Swift 4 Syntax:

    buttonA.isExclusiveTouch = true
    buttonB.isExclusiveTouch = true

Answer 6

You can also use below method. If you have two buttons or more, to prevent multiple push at a time.

for e.g,

[Button1 setExclusiveTouch:YES];

[Button2 setExclusiveTouch:YES];

Set this method in your viewDidLoad or viewWillAppear
