Fix multiple button click events in iOS?

Question

Is there any way to prevent multiple button click events. In my application i have a scenario where multiple button events are getting called when the user taps the button continuously. Even after adding a loading indicator still sometimes its happening. Is there any generic solution to handle this ?

@TuğberkKaanDuman exclusive touch wont work i guess. In my the issue is that multiple taps are detected and the code inside is executed more than once causing multiple navigations. — subin272, May 24 '18 at 13:07
@ShauketSheikh when i am tapping the button continuously multiple navigations are happening. I have added a loading indicator on button which covers the entire view so that user cant interact with UI. But still in some cases the button action executes more than once. — subin272, May 24 '18 at 13:10
@ShauketSheikh Tried this in case of UIBarbutton item but it didnt work. — subin272, May 24 '18 at 13:20

when you click on the button in the click method put code

btnClick.userInteractionEnabled = false;

it will not let user to click button anymore after you are done with the task put another line of code to enable the user to click on the button

btnClick.userInteractionEnabled = true;

Try this if you using UiButton

@IBAction func tapButton(sender: Any) {
    print("Tap")
    let btn = sender as! UIButton
    btn.isUserInteractionEnabled = false
}

Try this if you using UIBarButtonItem

   leftButton = UIBarButtonItem(image: UIImage(named: "backimage")!, style: UIBarButtonItemStyle.plain, target: self, action: #selector(self.toggleLeft))
    leftButton.title = "Back"

    navigationItem.leftBarButtonItem = leftButton


@objc public func toggleLeft() {
    print("tap")
    leftButton.isEnabled = false
//   self.navigationController?.popViewController(animated: true)
}

What to do in case of UIBarbuttonitem. It does not have “isUserInteractionenabled” property – subin272 May 24 '18 at 14:34

After trying out different ways like enabling/disabling the button and enabling/disabling the UI (which is not at all recommended) the best way I feel is to use a "bool" variable to check the button clicked status.

`
var isButtonTapped = false
@IBAction func tapButton(sender: Any) {
    print("Tap")
    if(!isButtonTapped){
    //Perform your operations or page navigations. After the navigation operation set the bool value to true.
    isButtonTapped = true;
  }
}`

Make sure you reset the bool value to false when navigating away from the ViewController. You can do that in ViewDidDisappear.
