Fix multiple button click events in iOS?

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 ?

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.

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)
}

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;
