无法解决错误：线程1：在swift XCODE中发出SIGABRT信号 [英] Can't resolve error: Thread 1: signal SIGABRT in swift XCODE

问题描述

我有一个常见的错误 - 线程1：信号SIGABRT。虽然我无法解决这个问题。我已经研究了更多关于这个错误的信息，我找到了类似的东西：只有当你在一个不存在的插座上调用时才会发生这个错误。我回头看了我的代码，寻找一些按钮，标签，图像或任何我不想要的东西，我只是找不到任何bug的踪迹！如果有人能发现一个错误或任何东西，这将是伟大的。谢谢！

I have the common error - "Thread 1: signal SIGABRT". Although I can't resolve this. I have researched more about this error, I found stuff like: This error only happens when you are calling on an outlet that doesn't exist. I've looked back into my code looking for some button, label, image or anything that I do not want, I just can't find any trace of the bug! If anyone can spot a bug or anything, that would be great. Thanks!

这是我的代码

import UIKit

class ViewController: UIViewController {

//Useful Variables
var cashCount:Int = 0
var cashIncome:Int = 1

//The cash displaying Outlets
@IBOutlet weak var errorDisplay: UILabel!
@IBOutlet weak var cashDisplayLabel: UILabel!
@IBOutlet weak var cashIncomeDisplayer: UILabel!

//The other outlets

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.
}

//When the cash is clicked call this func

@IBAction func CashClicked(_ sender: Any) {
    cashCount += cashIncome
    cashDisplayLabel.text = "Cash: $\(cashCount)"
}

//The store functions
@IBAction func BuyFoodFUNC(_ sender: Any) {
    if cashCount >= 10 {
        errorDisplay.text = "Success!"
        cashCount -= 10
    } else {
        errorDisplay.text = "Sorry, Not Enough Funds!"
    }
}

@IBAction func BuySubFUNC(_ sender: Any) {
    if cashCount >= 20 {
        errorDisplay.text = "Success!"
        cashCount -= 20
    } else {
        errorDisplay.text = "Sorry, Not Enough Funds!"
    }
}

@IBAction func BuyCarFUNC(_ sender: Any) {
    if cashCount >= 800 {
        errorDisplay.text = "Success!"
        cashCount -= 800
    } else {
        errorDisplay.text = "Sorry, Not Enough Funds!"
    }
}

@IBAction func BuyRVFUNC(_ sender: Any) {
    if cashCount >= 1000 {
        errorDisplay.text = "Success!"
        cashCount -= 1000
    } else {
        errorDisplay.text = "Sorry, Not Enough Funds!"
    }
}

@IBAction func BuyLapTopFUNC(_ sender: Any) {
    if cashCount >= 900 {
        errorDisplay.text = "Success!"
        cashCount -= 900
    } else {
        errorDisplay.text = "Sorry, Not Enough Funds!"
    }
}

@IBAction func BuyPhoneFUNC(_ sender: Any) {
    if cashCount >= 700 {
        errorDisplay.text = "Success!"
        cashCount -= 700
    } else {
        errorDisplay.text = "Sorry, Not Enough Funds!"
    }
}
@IBAction func UpgradeCashINCOME(_ sender: Any) {
    if cashCount >= 10 {
        errorDisplay.text = "Success!"
        cashCount -= 10
        cashIncome += 1
        cashIncomeDisplayer.text = "Income: $\(cashIncome)"
    } else {
        errorDisplay.text = "Sorry, Not Enough Funds!"
    }
}
}

这是截图

此外，如果您更改了名称一个插座，你将有如下图所示的东西。按x删除该连接并将圆圈拖到右侧并重新连接。

Also, if you changed the name of an outlet, you will have something like the image below. Press the x to delete that connection and drag the circle to the right of it and reconnect it.
