How to Get Xcode to Not Automatically Open Previously Opened Projects
提问by dtuckernet
So, I opened a xib file from an older project and it caused a crash. That's not the issue. The issue is that now when I restart Xcode, it tries to open all previously opened projects (and files) and the crash re-occurs. Where does Xcode store the list of previously open files, and how can I get it to start 'clean' without any open projects?
所以，我从一个旧项目打开了一个 xib 文件，它导致了崩溃。这不是问题。问题是，现在当我重新启动 Xcode 时，它会尝试打开所有以前打开的项目（和文件）并且再次发生崩溃。Xcode 在哪里存储以前打开的文件列表，我怎样才能让它在没有任何打开的项目的情况下开始“干净”？
Update: As a note - this is the latest version of Xcode 4.2 on Lion.
更新：请注意 - 这是 Lion 上最新版本的 Xcode 4.2。

Press option+Shiftwhen clicking on the Xcode icon in the dock. Xcode then starts without opening previously used projects. This is related to version Version 4.5.2 (4G2008a) but I am almost sure that I used it in older versions as well.
单击 Dock 中的 Xcode 图标时按option+ Shift。然后 Xcode 启动时不会打开以前使用过的项目。这与版本 4.5.2 (4G2008a) 有关，但我几乎可以肯定我也在旧版本中使用了它。

I've recently had a similar problem. I tried the methods above and could launch Xcode from the command line, but as soon as I tried to open from the finder, it would try to open the "bad" document and hang.
我最近遇到了类似的问题。我尝试了上述方法并且可以从命令行启动 Xcode，但是一旦我尝试从 finder 打开，它就会尝试打开“坏”文档并挂起。
I eventually resolved it by removing the contents of :
我最终通过删除以下内容来解决它：
~/Library/Autosave Information/
~/Library/Saved Application State/com.apple.dt.Xcode.savedState
This seems to have fixed it for me.
这似乎为我修复了它。

I just spent half the day stressing over a very similar issue. I had tried updating and reinstalling Xcode - but the problem still persisted. Thankfully, a few minutes ago, I managed to solve this by doing what your question states with the help of this post.
我只是花了半天时间来强调一个非常相似的问题。我曾尝试更新并重新安装 Xcode - 但问题仍然存在。值得庆幸的是，几分钟前，我在这篇文章的帮助下按照您提出的问题设法解决了这个问题。
Basically, I opened another Xcode project (it can be any file, though) from the terminal using the following command:
基本上，我使用以下命令从终端打开了另一个 Xcode 项目（但它可以是任何文件）：
open -a /Applications/Xcode.app app.xcodeproj/ --args -ApplePersistenceIgnoreState YES
This successfully launched Xcode with the standard 'Welcome to Xcode' dialog box you usually get. Hope that helps!
这成功地启动了 Xcode，并带有您通常会看到的标准“欢迎使用 Xcode”对话框。希望有帮助！

I was able to do it with the following command line in Mavericks:
我能够在小牛队中使用以下命令行来做到这一点：
open -a /Applications/Xcode.app --args -ApplePersistenceIgnoreState YES

Not specific to Xcode:
不特定于 Xcode：
Please make sure Close windows when quitting an applicationcheckbox is checked under System Preferences> General.
请确保Close windows when quitting an application选中System Preferences> 下的复选框General。

For me it wasn't a project that was causing the crash on startup, it was a particular file (an sks to be exact), so Kay's answer didn't work. When I went to open my particular project, it would still crash.
对我来说，这不是导致启动时崩溃的项目，而是一个特定的文件（准确地说是 sks），所以 Kay 的回答没有用。当我打开我的特定项目时，它仍然会崩溃。
I simply temporarily deleted the file. Then I opened the project, cleaned, and re-added the file, and all was well.
我只是暂时删除了该文件。然后我打开项目，清理并重新添加文件，一切都很好。

Instead of looking for the file that contains Xcode's settings, take a look at the settings themselves using the defaultscommand:
使用以下defaults命令查看设置本身，而不是查找包含 Xcode 设置的文件：
% defaults read com.apple.xcode | more
I notice two keys that might be relevant: NSRecentXCFileDocumentsand NSRecentXCProjectDocuments. Both appear to be arrays, so you could reset one like this:
我注意到两个可能相关的键：NSRecentXCFileDocuments和NSRecentXCProjectDocuments。两者似乎都是数组，因此您可以像这样重置一个：
% defaults write com.apple.xcode NSRecentXCFileDocuments -array ""
Alternately, you could use the defaults readcommand to dump the settings into a text file, edit that, and then use defaults writeto update the settings:
或者，您可以使用该defaults read命令将设置转储到文本文件中，对其进行编辑，然后用于defaults write更新设置：
% defaults read com.apple.xcode > xcsettings.plist
// edit xcsettins.plist with your favorite editor
% defaults write com.apple.xcode < xcsettings.plist

Given the project name "MyProject" in directory ~/Documents/Projects/MyProject do the following:
给定目录 ~/Documents/Projects/MyProject 中的项目名称“MyProject”，请执行以下操作：
cd ~/Documents/Projectsmv MyProject MyProject.xopen -a Xcode- close MyProject (Option+Command+W)
mv MyProject.x MyProjectopen -a Xcode
cd ~/Documents/Projectsmv MyProject MyProject.xopen -a Xcode- 关闭我的项目（Option+Command+W）
mv MyProject.x MyProjectopen -a Xcode
The this solved the crash for me... however my Storboard was corrupt. Fortunately the Time Machine backup of the folder was intact, I just restored it.
这为我解决了崩溃……但是我的 Storboard 已损坏。幸运的是，文件夹的 Time Machine 备份完好无损，我刚刚恢复了它。
