How to programmatically set action for barButtonItem in swift 3?

Question

Here is what I used previously,

var barButtonItem = UIBarButtonItem(image: backImgs, style: UIBarButtonItemStyle.plain, target: self, action: Selector(\"menu         


        

Answer 1

In Swift 3, you can add UIBarButtonItem like that,

let addButton = UIBarButtonItem(image:UIImage(named:"your_icon_name"), style:.plain, target:self, action:#selector(YourControllerName.buttonAction(_:)))
addButton.tintColor = UIColor.white
self.navigationItem.rightBarButtonItem = addButton

And handle button action like that,

func buttonAction(_ sender: UIBarButtonItem) {

}

Hope it helps.
