Question

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，它崩溃（抛出异常或其他东西）时，即使我撤消导致初始崩溃的代码，模拟器也会在下次运行时崩溃。

例如，在init方法中，我调用

 self = [super init];
 return self;

我可以运行一百次，每次都能正常运行。但如果我打电话

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

然后崩溃，应该如此。但是，如果我撤消随机消息调用，那么它再一次是

 self = [super init];
 return self;

我再次在模拟器上运行它，它崩溃了！即使我解除了导致崩溃的代码。当我点击运行时，它会显示XCode内部错误，当我点击显示详细信息时它会给我这个：

然后我点击继续，模拟器启动，应用程序崩溃，我得到：

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.

我尝试重新安装XCode。没有帮助！

我通过删除我的偏好文件解决了这个问题。清洁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，其名称中包含Xcode。我删除了所有三个，重新启动的XCode，一切正常。我正在使用XCode 4。

您是否尝试过清除iOS模拟器内容？转到iOS模拟器＆gt;清除所有内容。

然后在xCode中清理你的项目（在构建菜单中可用）（然后可能尝试另一个iOS SDK）。然后运行它。它应该有效，如果不重复清除/清理并重新启动你的mac。

任何模拟器崩溃后都需要重新启动XCode
