How stop another function from an UIButton function using Swift?

Question

I got two functions running called updatePrice and updateTime, and I want to stop them when I click an UIButton.

func updateTime() {...}
func updatePrice() {...}

// ..

@IBAction func Button(sender: UIButton) { 

    // What should I write here? 

}

Answer 1

Do something like NSOperation s do: make a boolean and periodically check it in those functions. Something like:

var stopFuncs = false

and later in functions at sensitive moments insert that:

if stopFuncs { return }

and add this to button code:

stopFuncs = true
