blocks|key|520081|text|我最近也遇到了类似的问题。我尝试了上面的方法，可以从命令行启动Xcode，但只要我试图从finder打开，它就会试图打开“坏”的文档并挂起。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|520082|我最终通过删除以下内容解决了这个问题：|520083|~/Library/Autosave+Information/

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.

I eventually resolved it by removing the contents of :

<pre><code>~/Library/Autosave Information/
~/Library/Saved Application State/com.apple.dt.Xcode.savedState
</code></pre>

This seems to have fixed it for me.

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 <a href="http://www.codeography.com/2011/10/05/prevent-xcode-from-opening-extra-projects.html" rel="noreferrer">this post</a>.

Basically, I opened another Xcode project (it can be any file, though) from the terminal using the following command:

<pre><code>open -a /Applications/Xcode.app app.xcodeproj/ --args -ApplePersistenceIgnoreState YES
</code></pre>

This successfully launched Xcode with the standard 'Welcome to Xcode' dialog box you usually get. Hope that helps!

Instead of looking for the file that contains Xcode's settings, take a look at the settings themselves using the <code>defaults</code> command:

<pre><code>% defaults read com.apple.xcode | more
</code></pre>

I notice two keys that might be relevant: <code>NSRecentXCFileDocuments</code> and <code>NSRecentXCProjectDocuments</code>. Both appear to be arrays, so you could reset one like this:

<pre><code>% defaults write com.apple.xcode NSRecentXCFileDocuments -array ""
</code></pre>

Alternately, you could use the <code>defaults read</code> command to dump the settings into a text file, edit that, and then use <code>defaults write</code> to update the settings:

<pre><code>% defaults read com.apple.xcode &gt; xcsettings.plist
// edit xcsettins.plist with your favorite editor
% defaults write com.apple.xcode &lt; xcsettings.plist
</code></pre>

blocks|key|520180|text|对我来说，这不是一个导致启动时崩溃的项目，而是一个特定的文件(确切地说是sks+)，所以Kay的答案不起作用。当我打开我的特定项目时，它仍然会崩溃。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|520181|我只是暂时删除了这个文件。然后我打开项目，清理并重新添加文件，一切都很好。|520182|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

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.

I simply temporarily deleted the file. Then I opened the project, cleaned, and re-added the file, and all was well.

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?

Update: As a note - this is the latest version of Xcode 4.2 on Lion.

所以，我打开了一个旧项目中的xib文件，它导致了崩溃。你没说到点儿上。问题是，现在当我重启Xcode时，它试图打开所有以前打开的项目(和文件)，崩溃再次发生。Xcode将以前打开的文件列表存储在哪里，以及如何在没有任何打开的项目的情况下让它“干净”地启动？更新:注意--这是Lion上Xcode 4.2的最新版本。
