这里使用Xcode 4.3.3修复磁盘权限解决。

另外:确保你没有包含信息。在您的构建阶段的plst文件->复制捆绑资源。如果是的话，把它从列表中删除!我可能会发生的小错误，但会把事情搞得很糟糕:S

这里使用Xcode 4.3.3修复磁盘权限解决。

在Xcode 4中重命名项目后，我经常遇到这个问题。

我可以通过编辑.plist文件中的Bundle Identifier来修复它。

在我重命名项目后，Bundle Identifier会变成这样:

com.yourcompany.${PRODUCT_NAME:rfc1034identifier}

改回如下:

com.yourcompany.${PRODUCT_NAME}

将停止Xcode挂起并允许应用程序运行。

就像Rob说的，还要检查“标识符”默认应该是“com.yourcompany”。我错误地更改了“yourcompany”，这导致了上面提到的相同问题。

I was having this very annoying issue since a long time too. I've 3 different XCode versions installed and I'm not sure whether it's the reason or not that none of the above solutions worked for me. But here is the solution I finally found: I don't kill the running Simulator, I just try to launch it again using a Spotlight search, enter "Simu" and you should find it in Applications, then hit Enter. As it's yet running it will magically start my app that was frozen/locked/waiting for attachment. It works perfectly for me now and I hope it will also work for some (all?) of you.

顺便说一句，我用Cmd+空格来调用Spotlight，这样就可以非常快速地解冻模拟器而不使用鼠标。
