How can I send button and button2 into my pressButton2 function? I need to change color of button and button2 when user will touch button2...
When my button2.addTarget looks like this, I got an error: 'Expected expression in list of expressions'.
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let button = UIButton(frame: CGRect(x: 10, y: 50, width: 100, height: 100))
button.backgroundColor = UIColor.gray
button.setTitle("123", for: [])
button.addTarget(self, action: #selector(pressButton(button:)), for: .touchUpInside)
////// sec button
let button2 = UIButton(frame: CGRect(x: 120, y: 50, width: 100, height: 100))
button2.backgroundColor = UIColor.gray
button2.setTitle("1234", for: [])
button2.addTarget(self, action: #selector(pressButton2(button2:, button:)), for: .touchUpInside)
self.view.addSubview(button)
self.view.addSubview(button2)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func pressButton(button: UIButton) {
NSLog("pressed!")
if button.backgroundColor == UIColor.gray {
button.backgroundColor = UIColor.red
}else{
button.backgroundColor = UIColor.gray
}
}
func pressButton2(button2: UIButton, button:UIButton) {
NSLog("pressed!")
if button2.backgroundColor == UIColor.gray {
button2.backgroundColor = UIColor.red
}else{
button2.backgroundColor = UIColor.gray
}
}
}
