I am trying to pass an extra parameter to the buttonClicked action, but cannot work out what the syntax should be in Swift.
button.addTarget(self, action: "buttonClicked:", forControlEvents: UIControlEvents.TouchUpInside)
Any my buttonClicked method:
func buttonClicked(sender:UIButton)
{
println("hello")
}
Anyone any ideas?
Thanks for your help.
You cannot pass custom parameters in addTarget:
.One alternative is set the tag
property of button and do work based on the tag.
button.tag = 5
button.addTarget(self, action: "buttonClicked:",
forControlEvents: UIControlEvents.TouchUpInside)
Or for Swift 2.2 and greater:
button.tag = 5
button.addTarget(self,action:#selector(buttonClicked),
forControlEvents:.TouchUpInside)
Now do logic based on tag
property
@objc func buttonClicked(sender:UIButton)
{
if(sender.tag == 5){
var abc = "argOne" //Do something for tag 5
}
print("hello")
}
