Swift 3 - 线程 1 : Signal SIGABRT Unrecognised selector sent to Instance

Question

有谁能帮我解决这个问题吗？我已经尝试解决这个问题几个小时了，但到目前为止还没有任何效果。每次我单击按钮时，它都会立即导致错误“线程 1:信号 SIGABRT”。

这是代码(注意:它仍在进行中):

import UIKit
class ViewController: UIViewController {
@IBOutlet var Sec1: UILabel!
@IBOutlet var Sec2: UILabel!
@IBOutlet var Sec3: UILabel!
@IBOutlet var Sec4: UILabel!
@IBOutlet var Sec5: UILabel!
@IBOutlet var Sec6: UILabel!
@IBOutlet var Sec7: UILabel!
@IBOutlet var Sec8: UILabel!
@IBOutlet var Sec9: UILabel!


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
var x = 2
   // if (x%2 == 0) {
    @IBAction func ButtonPressed(Button1: UIButton) {
   Sec1.text = "X"
    }    
}

这是错误:

您能检查一下 @IBAction 函数 ButtonPressed() 与 Storyboard之间的连接吗？您可以从 Storyboard 上的“连接检查器”进行检查。
