Get button pressed id on Swift via sender
You can set a tag
in the storyboard for each of the buttons. Then you can identify them this way:
@IBAction func mainButton(sender: UIButton) {
println(sender.tag)
}
EDIT: For more readability you can define an enum with values that correspond to the selected tag. So if you set tags like 0
, 1
, 2
for your buttons, above your class declaration you can do something like this:
enum SelectedButtonTag: Int {
case First
case Second
case Third
}
And then instead of handling hardcoded values you will have:
@IBAction func mainButton(sender: UIButton) {
switch sender.tag {
case SelectedButtonTag.First.rawValue:
println("do something when first button is tapped")
case SelectedButtonTag.Second.rawValue:
println("do something when second button is tapped")
case SelectedButtonTag.Third.rawValue:
println("do something when third button is tapped")
default:
println("default")
}
}
If you want to create 3 buttons with single method then you can do this by following code...Try this
Swift 3
Example :-
override func viewDidLoad()
{
super.viewDidLoad()
Button1.tag=1
Button1.addTarget(self,action:#selector(buttonClicked),
for:.touchUpInside)
Button2.tag=2
Button2.addTarget(self,action:#selector(buttonClicked),
for:.touchUpInside)
Button3.tag=3
Button3.addTarget(self,action:#selector(buttonClicked),
for:.touchUpInside)
}
func buttonClicked(sender:UIButton)
{
switch sender.tag
{
case 1: print("1") //when Button1 is clicked...
break
case 2: print("2") //when Button2 is clicked...
break
case 3: print("3") //when Button3 is clicked...
break
default: print("Other...")
}
}
You can create an outlet for your buttons and then implement:
@IBAction func mainButton(sender: UIButton) {
switch sender {
case yourbuttonname:
// do something
case anotherbuttonname:
// do something else
default: println(sender)
}
}
Swift 4 - 5.1
@IBAction func buttonPressed(_ sender: UIButton) {
if sender.tag == 1 {
print("Button 1 is pressed")
}
}
You have to set tag
value to what you need and access it with
sender.tag
