问题描述
我试图寻找答案，但是我不能精确地定义术语，而不会一直陷入错误的线程中.
I've tried to search for the answer but I cannot precisely define the terms without falling under wrong threads all the time.
发生了什么事:偶然地，我选择了 file.m 中的所有代码并将其全部删除.它成为完整的空白文档.当我按Ctrl + Z撤消操作时， xcode崩溃了.
What happened:Accidentally I've selected all the code inside a file.m and deleted it all.It became a full blank document. When I pressed Ctrl+Z to UNDO it, the xcode crashed.
问题:当我重新打开xcode(崩溃后)时，文件仍然全部空白(崩溃前几秒钟自动保存为空白文件)-全部丢失我的代码. 我无法使用UNDO 对此进行救助，因为它已自动保存并崩溃.
The problem:When I reopened the xcode (after the crash) , the file was still all blank (It was autosaved seconds before the crash as a blank document) - losing all my code. I could not use UNDO to rescue me on this because it autosaved and crash.
我需要什么:有没有办法在自动保存/崩溃之前将文件恢复/还原到以前的状态?
What do I need:Is there a way to recover/revert my file to a previous state before this autosaving/crash?
其他信息:源代码控制:我无法使用它，因为最后一次提交"是6月27日.
Extra information:Source Control: I can't use it because the last "commit" was June 27.
Time Machine:没有外部HD可以使用它.它被禁用.
Time Machine: Don't have external HD to use it. It is disabled.
更新1:我按下了放弃最后更改"按钮，并且file.m恢复为6月27日保存的文件.因此，还有一个问题:直到现在都失去了所有的工作.
Updated 1: I've pressed the button "discard last change" and the file.m reverted to the file saved June 27.So, one more problem: Lose all the months of work up until now.
更新2:我找到了解决方法，并在下面发布.但是我需要等到明天才能接受它作为答案.
Update 2: I've found the solution, and posted below. But I need to wait until tomorrow to accept it as answer.
更新3:我对文本进行了重新编辑以阐明我的问题.
Update 3: I've reedited the text to clarify my problem.
推荐答案
哦！我修理它.我已经使用 TextEdit 打开了 file.m .然后，我浏览到:文件>恢复为>浏览所有版本
Oh! I fix it.I've opened the file.m with TextEdit.Then I browse to:File > Revert To> Browse All Versions
它把我带到了一个保存了所有文件版本的地方，在这里我可以使用时间轴搜索所需的确切时间.
It led me to a place with all saved versions of the file, where I could search with a timeline the exact moment I need.
我已经找到了空白/崩溃时刻之前的版本，并复制了文本，将其粘贴到xcode上的file.m中(也已保存，将其提交给源代码管理以确保安全)，现在一切正常.我可以再次恢复所有代码.
I've find the version previous to the blank/crash moment, and copied the text, paste it at file.m on xcode( also saved, commit it to source control for safety) and everything is ok now. I could recover all my code again.
这篇关于如何将.m文件还原/恢复到以前的版本? (错误地自动保存空白，xcode崩溃-没有源代码管理，没有Time Machine)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
