ios - 应用程序在 IAP 后崩溃 - 仅在 podfiles 更新后

Question

我在一个应用程序中设置了一个 IAP，还有一些 Cocoapods:

  - Firebase/AdMob (4.8.0):
    - Firebase/Core
    - Google-Mobile-Ads-SDK (= 7.27.0)
  - Firebase/Core (4.8.0):
    - FirebaseAnalytics (= 4.0.5)
    - FirebaseCore (= 4.0.13)
  - Firebase/Crash (4.8.0):
    - Firebase/Core
    - FirebaseCrash (= 2.0.2)
  - FirebaseAnalytics (4.0.5):
    - FirebaseCore (~> 4.0)
    - FirebaseInstanceID (~> 2.0)
    - GoogleToolboxForMac/NSData+zlib (~> 2.1)
    - nanopb (~> 0.3)
  - FirebaseCore (4.0.13):
    - GoogleToolboxForMac/NSData+zlib (~> 2.1)
  - FirebaseCrash (2.0.2):
    - FirebaseAnalytics (~> 4.0)
    - FirebaseInstanceID (~> 2.0)
    - GoogleToolboxForMac/Logger (~> 2.1)
    - GoogleToolboxForMac/NSData+zlib (~> 2.1)
    - Protobuf (~> 3.1)

IAP 和上述所有框架都运行完美!完全没有问题。

一旦我进行了 pod 更新，事情就开始变糟了。

pod 更新后，更新后的版本如下:

pod :

  - Firebase/AdMob (4.10.1):
    - Firebase/Core
    - Google-Mobile-Ads-SDK (= 7.29.0)
  - Firebase/Core (4.10.1):
    - FirebaseAnalytics (= 4.1.0)
    - FirebaseCore (= 4.0.17)
  - Firebase/Crash (4.10.1):
    - Firebase/Core
    - FirebaseCrash (= 2.0.2)
  - FirebaseAnalytics (4.1.0):
    - FirebaseCore (~> 4.0)
    - FirebaseInstanceID (~> 2.0)
    - GoogleToolboxForMac/NSData+zlib (~> 2.1)
    - nanopb (~> 0.3)
  - FirebaseCore (4.0.17):
    - GoogleToolboxForMac/NSData+zlib (~> 2.1)
  - FirebaseCrash (2.0.2):
    - FirebaseAnalytics (~> 4.0)
    - FirebaseInstanceID (~> 2.0)
    - GoogleToolboxForMac/Logger (~> 2.1)
    - GoogleToolboxForMac/NSData+zlib (~> 2.1)
    - Protobuf (~> 3.1)

此 pod 更新后 - 我的 IAP 在 100% 的时间内因成功购买而崩溃。代码绝对没有任何变化。只是对上面列出的最新框架的 pod 更新。

一旦 IAP 完成(并弹出“您已准备就绪!”成功警报)，我会遇到以下崩溃:

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb) 

    libsystem_kernel.dylib`__pthread_kill:

这是 Firebase 崩溃报告记录的内容:

-[__NSCFBoolean timeIntervalSince1970]: unrecognized selector sent to instance 0x1b6f8a878

一些注意事项:

• 代码没有任何变化。
• Cocoapods 已在终端中更新。步骤:1. CD 到目录，2. $ pod update
• 我在更新 Cocoapods 之前测试了 IAP - 一切正常；应用没有崩溃。
• 我在 Cocoapod 更新后测试 IAP 之前清理了一个项目。
• 在多个设备上崩溃 -(iOS 11.2.6 和 11.2.1)。

由于我只更新了 pod，导致此崩溃的原因是什么？

赏金更新:

我已经为这个问题添加了赏金，因为我现在正在其他项目中体验它。我有一个旧项目，我想更新 Pod(Firebase/Firebase Crash/Google Ads)。以下是我采取的具体步骤:

1. CD 到项目目录。
2. Pod 更新。 Cocoapods 根本没有给我任何错误。

在 Xcode 中，我运行了我更新了 Podfile 的项目...我购买了一个 IAP，它在完成后立即崩溃。同样，这不会在 pod 文件更新之前发生!在我运行 pod update 之前，IAP 工作正常。

对于新冒犯的损坏项目，我删除了 Podfile、Podfile.lock 和 Pods 目录。我从一个旧项目中拖入了相同的文件和目录。完美运行，没有任何崩溃。

此问题仅在 pod 更新后仍然存在。我迷路了..

Answer 1

要找到调用 TimeInterval 的位置，我会为 Bool 添加一个公共(public)扩展，这样您就可以向它添加一个断点并进行相应的修改。

像这样:

public extension Bool {
    public var timeIntervalSince1970:TimeInterval {
        get {
            // Add breakpoint here
            return 0
        }
    }
}

更新:

我没能认出你的崩溃提到了 NSCFBoolean 而不是 Bool。 据我了解，NSCFBoolean 是桥接 CFBoolean 的私有(private)类，因此您不能扩展它，但也许它可以通过扩展 CFBoolean 来工作。有关 NSCFBoolean 的更多信息:https://nshipster.com/bool/

请尝试添加此扩展和断点:

public extension CFBoolean {
    var timeIntervalSince1970: TimeInterval {
        get {
            // Add breakpoint here
            return 0
        }
    }
}
