I am working on an app where I need to have a delegate method for button to identify that which button is pressed by user.Below is the code , please let me know where I am making mistake.Delegate is not working,there is no error,no crash.
import UIKit
@objc protocol SAlertViewDelegate {
optional func clickedButtonTitle(title:String)
}
class CustomAlertView: UIView {
var delegate:SAlertViewDelegate?
func button1Action(sender: UIButton?) {
let titleLabel=sender?.titleLabel?.text
self.delegate?.clickedButtonTitle!(titleLabel!)
removeFromMainView()
}
}
View Controller :-
import UIKit
class CurrentImageVC: UIViewController,SAlertViewDelegate
{
var alert:CustomAlertView=CustomAlertView()
override func viewDidLoad() {
super.viewDidLoad()
alert.delegate=self
}
//MARK: Custom Delegate
func clickedButtonTitle(title:String)
{
println(title)
}
}
The problem is that you need to assign delegate to object which you are using to add the subview.
let alertSubView: CustomAlertView = CustomAlertView()
alertSubView.frame=CGRectMake(0,0,1024,768)
alertSubView.delegate=self
self.view.addSubview(alertSubView)
