提前致谢。
编辑：我想使用Xcode 3（我通常使用4）的唯一原因是我想在iOS 3.x上测试我的iOS应用程序。
答案 0 :(得分：1)
Mac OS X Lion不正式支持Xcode 3。
升级到Xcode 4（你仍然可以使用10.7以上的Mac OS X版本），或者坚持使用Snow Leopard。
否则，如果您真的想使用Lion和Xcode 3，我认为您应该安装10.6虚拟机，这样您就可以运行Xcode 3。

我听说有人说他们不能在狮子身上运行xcode，所以如果你想使用xcode3，我认为可以选择雪豹。最好的。
答案 2 :(得分：1)
升级到Xcode 3.2.6似乎可以解决问题。
