在两个嵌套子类中调用super.viewDidLoad（）时，我遇到了一个Swift的无限循环 [英] I'm getting an infinite loop with Swift when calling super.viewDidLoad() in two nested subclasses

问题描述

我正在使用一个用Swift编写的iOS应用程序。我有一个UITabBarController的子类，然后一个嵌套的子类：

I'm working on an iOS app written in Swift. I have a subclass of UITabBarController, and then a nested subclass:

class HWTabBarController: UITabBarController {
    override func viewDidLoad() {
        super.viewDidLoad()
        ...
    }
}

class MainTabBarController: HWTabBarController {
    override func viewDidLoad() {
        super.viewDidLoad()
        ...
    }
}

b $ b

这在iOS模拟器中正常工作，甚至当我在我的iPhone上调试应用程序时。
但是当我归档应用程序并将其发送到我的手机与TestFlight它崩溃。

This works fine in the iOS simulator, and even when I'm debugging the app on my iPhone. But it crashes when I archive the app and send it to my phone with TestFlight.

我的崩溃日志充满了无限循环：

My crash logs are filled with this infinite loop:

22  HDWR                           0x00145e10 @objc HDWR.MainTabBarController.viewDidLoad (HDWR.MainTabBarController)() -> () (MainTabBarController.swift:16)

30  HDWR                           0x0014ea00 HDWR.HWTabBarController.viewDidLoad (HDWR.HWTabBarController)() -> () (HWTabBarController.swift:24)
31  HDWR                           0x00145e10 @objc HDWR.MainTabBarController.viewDidLoad (HDWR.MainTabBarController)() -> () (MainTabBarController.swift:16)

voidParamHandler 指令，为什么会导致 MainTabBarController.viewDidLoad ？

What's the voidParamHandler instruction, and why does it lead back to MainTabBarController.viewDidLoad?

这里？或者这是Swift中的错误？

Am I doing something wrong here? Or is this a bug in Swift?

推荐答案

您使用 New Relic 在您的应用程序？ （我猜所有的 NRMA__voidParamHandler 引用你是）我有这个确切的问题。我禁用了New Relic SDK和从Testflight下载的构建停止崩溃。我还没有报告错误，但你/我/我们可能应该。

Are you using New Relic in your app? (I'm guessing from all those NRMA__voidParamHandler references that you are.) I had this exact problem. I disabled the New Relic SDK and builds downloaded from Testflight stopped crashing. I haven't reported a bug yet, but you/I/we probably should.
