Swift: how to disable user interaction while touch action is being carried out?

Question

I'm working with sprite kit and if the user touches the screen, the actions within

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    /* Called when a touch begins */

    for touch: AnyObject in touches {
    }
}

are carried out. While they're being carried out, however, the user can still tap the screen and the app tries to run the actions again.

How do I disable touch interaction/the actions within the touch func while the actions are running?

Answer 1

Try to get the view from the touch object and then dissable the user interaction on it.

touch.view.isUserInteractionEnabled = false

Answer 2

To disable user interaction app-wide, use:

UIApplication.shared.beginIgnoringInteractionEvents()
UIApplication.shared.endIgnoringInteractionEvents()

(as of Swift 5 this is deprecated)

Answer 3

In Swift 3.0 is:

self.view.isUserInteractionEnabled = false

Answer 4

You can use boolean class variable to stop interaction while method is performing, and after that you can just change value of boolean, at the end of the method.

Use UIApplication.shared.beginIgnoringInteractionEvents() at the end of the first method, then change value of boolean and then use another method with start line UIApplication.shared.endIgnoringInteractionEvents().
