【问题描述】：

我正在尝试保存 UISwitch 结果并使用它们来填充 Parse.com 推送通知的“通道”。我遵循了 Parse Guide，但每次尝试单击保存开关值的保存按钮时，我都会得到一个 SIGABRT。非常感谢任何帮助

@IBAction func Save(sender: AnyObject) 

    if Athletics.on
        let currentInstallation = PFInstallation.currentInstallation()

    elselet currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.removeObject("Athletics", forKey: "channels")
        currentInstallation.saveInBackground()

【问题讨论】：

要识别哪个语句产生了错误，设置一个异常断点：在Xcode的断点导航器中，单击左下角的加号并选择“添加异常断点...”，然后按回车键。运行您的应用程序，它会在有问题的指令处停止。

为什么不更新所有频道然后在最后保存一次...

【参考方案1】：

问题不在于您的代码，而在于您的 main.storyboard。当故事板元素连接到不再存在的其他元素或插座时，SIGABRT 错误会显示。

修复此错误：

转到您的 main.storyboard 点击其中一个元素（例如 UILabel 等） 单击连接检查器（看起来像圆圈中的箭头） 查看它是否连接到不存在的东西并删除它/它们 对所有元素执行步骤 2 到 4
