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 定义良好。
我不知道如何在 xcode 中读取堆栈跟踪，有人可以帮忙提供一些指导吗？

这里是代码失败的地方: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()
}
最佳答案
尽管这是一篇旧文章，但请在 Xcode 中检查用户定义的运行时属性。您可能已经在那里声明了默认属性，删除它应该可以解决您的问题。
关于ios - 无法设置(keyPath)此类上的用户定义的检查属性不符合键 keyPath 的键值编码，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35241514/
