Ios 任何模拟器崩溃后都需要重新启动XCode

就在最近，我开始在XCode上遇到很多麻烦。每当我在模拟器上运行我的应用程序时，它就会崩溃（抛出异常或其他东西），下一次我运行它时，模拟器就会崩溃，即使在我撤消导致最初崩溃的代码之后也是如此

例如，在init方法中，我调用

 self = [super init];
 return self;

我可以运行它一百次，每次运行都很好。但如果我打电话

 self = [super init];
 [super wrlgnqelrguqrngouqerngerg];
 return self;

然后它崩溃了，这是应该的。但是如果我撤销随机消息调用，那么它再次

 self = [super init];
 return self;

我再次在模拟器上运行它，它崩溃了！即使我解开了导致崩溃的代码。当我单击run时，它会显示XCode internal error，当我单击show details时，它会显示以下内容：

我已尝试重新安装XCode。没用

您是否尝试过清除iOS模拟器的内容？转到iOS模拟器>清除所有内容

然后在xCode中清理您的项目（可在build菜单中找到）（然后可能尝试另一个iOSSDK）。

然后运行它。它应该已经工作了，如果没有重复清理/清理并重新启动mac

我通过删除首选项文件解决了这个问题。清理项目和模拟器不起作用。我在username/library/preferences中找到了该文件。它被称为com.apple.Xcode.plist。还有一些其他文件的名字中有Xcode。我删除了所有三个，重新启动了XCode，一切正常。我使用的是XCode 4。

您使用的是Beta吗？提交一个bug。即使你不是，你也可以向苹果公司提交一个bug

Couldn't register NI.nipod-app-final with the bootstrap server. Error: unknown error code.
This generally means that another instance of this process was already running or is hung in the debugger.
