IAP后，应用程序崩溃-仅在更新podfile之后 [英] App is crashing after an IAP - only after podfiles were updated

问题描述

我在应用程序中有一个IAP设置，还有一些Cocoapods：

I have an IAP setup in an app, along with a few 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 and all of the above frameworks are working perfect! No problems at all.

一旦我进行了Pod更新，事情就开始往南走。

pod更新后，以下是更新的版本：

After a pod update, here are the updated versions:

PODS：

  - 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成功购买商品时100％崩溃。绝对代码没有改变。只是对上面列出的最新框架的一个pod更新。

After this pod update - my IAP crashes on a successful purchase 100% of the time. Absolutely nothing changed in code. Just a pod update to the newest frameworks listed above.

IAP完成后，我将收到以下崩溃消息（并且弹出您已准备就绪！的提示）上）：

I am getting the following crash once the IAP completes (and the "You're all set!" success alert pops up):

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

这是Firebase崩溃报告记录的内容：

Here is what Firebase crash reporting is logging:

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

一些注意事项：

Some items to note:

• 代码没有任何变化。


• 可可豆在终端中进行了更新。步骤：1. CD到dir，2. $ pod update


• 在更新Cocoapods之前，我测试了IAP-一切正常。应用程序没有崩溃。


• 在Cocoapod更新后，我在测试IAP之前完成了项目清理。


• 在多台设备上崩溃-（iOS 11.2。 6和11.2.1）。

• Nothing at all changed in code.
• Cocoapods were updated in terminal. Steps: 1. CD to dir, 2. $ pod update
• I tested the IAP before updating Cocoapods - everything worked flawless; the app did not crash.
• I did a project clean before testing the IAP after Cocoapod update.
• Crashing on multiple devices - (iOS 11.2.6 and 11.2.1).

由于我仅更新了广告连播，导致此崩溃的原因是什么？

赏金更新：

我为这个问题添加了赏金，因为我现在在其他项目上经历过。我有一个旧项目，想更新Pods（Firebase / Firebase崩溃/ Google Ads）。这是我采取的确切步骤：

I have added a Bounty to this question because I am now experiencing it on other projects. I had an old project that i wanted to update the Pods (Firebase / Firebase Crash / Google Ads). Here are the exact steps I took:

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，我运行了一个我更新了Podfile的项目...购买IAP，完成后立即崩溃。同样，在pod文件更新之前不会发生这种情况！在运行pod update之前，IAP可以正常工作。

Within Xcode, I run the project whose Podfile I updated... I go through purchasing an IAP and it crashes as soon as it's complete. Again, this does not happen before the pod file was updated! The IAP works fine until I run pod update.

对于新近损坏的项目，我删除了Podfile，Podfile.lock和Pods目录。我从一个较旧的项目中拖动了相同的文件和目录。完美运行而不会崩溃。

With the newly offended broken project, I removed Podfile, Podfile.lock, and Pods directory. I dragged the same files and directory in from an older project. Works perfect without any crashing.

此问题仅在pod更新后仍然存在。我迷路了。

This problem is persisting ONLY after pod update. I'm lost..

推荐答案

我发现当 registerDefaults：用于注册用户首选项时会发生此崩溃与IAP产品标识符相同的密钥。

I found out that this crash occurs when registerDefaults: is used to register a user preference key that is the same as the IAP product identifier.

当与IAP产品ID密钥相同的NSUserDefaults密钥具有默认的prefs值注册时，总是发生此异常：

This exception always occurs when the NSUserDefaults key that is the same as the IAP product ID key is has a default prefs value registered like so:

#define kTipPurchasedIAPProductIdKey @"tipAdditional99Cents"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // Override point for customization after application launch.


  if (YES) {
      //Firebase initialization
      [FIRApp configure];
      [[FIRConfiguration sharedInstance] setLoggerLevel:FIRLoggerLevelMin];
  }

    //Register user defaults
    [[NSUserDefaults standardUserDefaults] registerDefaults:@{
                                                              kTipPurchasedIAPProductIdKey: @NO
                                                              }];
}

在这种情况下，IAP产品ID密钥（可用于验证是否iAP存在，等等）为tipAdditional99Cents。当交易返回购买/还原状态时，将发生崩溃。

In this case the IAP product ID key (that you would use to validate whether the iAP exists, etc) is tipAdditional99Cents. The crash occurs when the transaction returns as purchased/restored.

当前的解决方法是在用户默认值中注册其他密钥，而不是实际的IAP产品ID。

The current workaround is to register a different key in the user defaults instead of the actual IAP product ID.

我在其Github存储库中向Google Firebase报告了此处，他们将在下一版本（6.13.0，已修复14NOV2019）中修复该错误。

I reported it to Google Firebase on their Github repository here and they will fix the bug in the next release (6.13.0, fixed 14NOV2019).
