ios - 更新 Xcode 后的 EXC_BAD_ACCESS (SIGABRT)

Question

在我将 Xcode 从 9.4 更新到 9.4.1 和 Xcode 的 命令行工具(macOS High Sierra 版本 10.13)(6 月 18 日更新)后，我一直收到以下错误提交我的应用程序以供审核。

我已经尝试了我在网上找到的任何东西:

1. 删除obj和bin目录
2. 从头开始重新创建 LaunchScreen.storyboard。
3. 将所有库更新到最新
4. 重新安装VS
5. 重新安装 Xcode

我在我的应用程序中使用以下库:

1. 谷歌注册
2. xamarin 身份验证
3. ffimageloading
4. newtonsoft.json

我的 Visual Studio 是最新版本，这是我的发布设置:

这种崩溃在我的模拟器和我的 iPhone 7 上从未发生过。 是否知道我做错了什么？

Answer 1

当前VS 2017 mac存在一个奇怪的bug；当我打开 Storyboard时，它将作为 iPhone 8 plus 板打开。当我将其更改为 iPhone 4s 时，有时它会删除特定 UITableView 的名称。这会导致空指针异常。

我不知道为什么 VS 这样做，但这是我问题的根源。

顺便说一句，只有当我的构建配置是调试/发布 - iPhone 时才会发生这种情况。
