我正在开发一个 iPhone 应用程序。我对Xcode不熟悉,所以请多多包涵。我有 iOS 4.1 设备 SDK。当我在“Active ...”下拉框中选择“Simulator”时,我的应用程序编译没有错误并在 iPhone 模拟器中运行。
但是,当我在下拉框中选择“设备”时,我收到以下有关重复符号的链接器错误:

这个错误很奇怪,因为它抱怨 _RedirectionLimit 被发现两次——在同一个文件中!libClientDal.a(libASIHTTPRequest.a-armv6-master.o)
是有问题的图书馆。有人可以帮助我了解发生了什么吗?这个库最初是如何正确编译的?或者链接器可能试图两次包含同一个库?
这个类似问题中提供的解决方法对我不起作用。
如果您需要更多信息,我很乐意提供——正如我所说,我是 Xcode 开发的新手。
