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()
        currentInstallation.addUniqueObject("Athletics", forKey: "channels")
        currentInstallation.saveInBackground()
    }else{let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.removeObject("Athletics", forKey: "channels")
        currentInstallation.saveInBackground()
    }


    if Academics.on{
        let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.addUniqueObject("Academics", forKey: "channels")
        currentInstallation.saveInBackground()
    }else{let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.removeObject("Academics", forKey: "channels")
        currentInstallation.saveInBackground()
    }

    if LinkCrew.on{
        let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.addUniqueObject("LinkCrew", forKey: "channels")
        currentInstallation.saveInBackground()
    }else{let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.removeObject("LinkCrew", forKey: "channels")
        currentInstallation.saveInBackground()
    }

    if Events.on{
        let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.addUniqueObject("Events", forKey: "channels")
        currentInstallation.saveInBackground()
    }else{let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.removeObject("Events", forKey: "channels")
        currentInstallation.saveInBackground()
    }

    if Parents.on{
        let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.addUniqueObject("Parents", forKey: "channels")
        currentInstallation.saveInBackground()
    }else{let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.removeObject("Parents", forKey: "channels")
        currentInstallation.saveInBackground()
    }

    if Day1Day2.on{
        let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.addUniqueObject("Day1Day2", forKey: "channels")
        currentInstallation.saveInBackground()
    }else{let currentInstallation = PFInstallation.currentInstallation()
        currentInstallation.removeObject("Day1Day2", 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...

【解决方案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
