ios - 无法设置 (keyPath) 用户定义的此类上的检查属性对于键 keyPath 不符合键值编码

Question

我的 swift 应用程序在运行时失败。我该如何解决这个问题？

我已经检查过，avgTime_text 定义明确。

我不知道如何读取 xcode 中的堆栈跟踪，有人可以提供一些指导吗？

这是代码失败的地方:AppDeligate 下的 window?.makeKeyAndVisible()

func launchStoryboard(storyboard: Storyboard) {
    window = UIWindow(frame: UIScreen.mainScreen().bounds)
    UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: .Slide)
    let storyboard = UIStoryboard(name: storyboard.rawValue, bundle: nil)
    let controller = storyboard.instantiateInitialViewController()!
    if (controller is InlineMainViewController ){
        mainViewController = controller as! InlineMainViewController
    }
    window?.rootViewController = controller
    window?.makeKeyAndVisible()
}

虽然这是一篇旧文章，但请在 Xcode 中查看用户定义的运行时属性。您可能在那里声明了一个默认属性，删除它应该可以解决您的问题。
