应用错误收集

使用Git。如果您不知道它是什么，请查看它。同时，这是tutorial或two。

要在Xcode中使用它，在创建项目时，请务必创建一个git repo：

然后一定要经常提交。 Xcode有一个内置的Git GUI，因此更容易：

然后，如果你做任何你不应该做的事情，你可以放弃所有的更改（参见上面的截图，或者如果这对你没有帮助，你可以：

打开“终端”应用
git log到项目目录
运行q
在破坏一切之前找到提交
复制提交哈希
键入git reset --hard <THE-HASH-YOU-COPIED>以退出日志

那应该为你做。

创建项目时，检查＆＃39;在我的Mac上创建git存储库。

然后在您完成一个次要部分时提交更改，并为提交提供评论，以便您在查看历史记录时所做的更改（快速概述）。

使用git，您可以快速还原更改并返回到某些修订版，就像在TimeMachine中一样。

有关详细信息，请访问git's webpage。

当我在 Xcode IDE 中“保存”时会发生什么？

当您点击“保存”时，您所做的更改将保存到磁盘。 XCode 不会自动执行此操作。如果它崩溃，您可能会丢失上次保存到磁盘后编写的所有代码。但在某些情况下，XCode 即使没有点击“保存”按钮也会将更改保存到磁盘。

<块引用>

Xcode 自动保存对源、项目和工作区的更改工作时的文件。此功能不需要配置，因为 Xcode 会持续跟踪您的更改并将它们保存在内存中。 Xcode 然后随时将这些更改写入磁盘：

构建并运行您的应用

将文件提交到源代码存储库

关闭项目

退出 Xcode
