这是我尝试在Xcode上运行的代码，其想法是当我按下按钮时，它将显示背景和徽标，但是，当我按下按钮时，它直接将我带入错误
import UIKit
class ViewController: UIViewController {
@IBOutlet weak var coolLogo: UIImageView!
@IBOutlet weak var coolBg: UIImageView!
@IBOutlet weak var uncoolButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
@IBAction func makeMeNotSoUncoolButton(sender: AnyObject) {
coolLogo.hidden = false
coolBg.hidden = false
uncoolButton.hidden = true
print ("Its running")
}
}
这是我收到的错误

好像您未正确连接uncoolButton插座或makeMeNotSoUncoolButton操作。
