ios - SIGABRT - 目标解析推送通知

Question

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“ channel ”。我遵循了解析指南，但每次我尝试单击保存开关值的保存按钮时，我都会收到一个 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()
    }


}

问题不在于您的代码，而在于您的 main.storyboard。 SIGABRT 错误显示 Storyboard元素何时连接到不再存在的某个其他元素或导出。

要修复此错误:

1. 转到您的主要 Storyboard
2. 点击您的元素之一(例如 UILabel 等)
3. 单击连接检查器(看起来像圆圈中的箭头)
4. 查看它是否连接到不存在的东西并删除它/它们
5. 对所有元素执行第 2 步到第 4 步
