我在XCode 4中实现PayPal库时遇到了麻烦。
当我尝试构建项目时出现此错误：

在网上搜索我发现从XC3传递到XC4时这是一个典型的错误。也许图书馆没有更新。但是你看到的那个文件似乎是不可编辑的。

Searching on the web I found that this is a tipical error when passing from XC3 to XC4. Maybe the Library isn't updated. But that file .a that you see there seems to be uneditable.

推荐答案

解决了。必须加载3个框架：libXML，Security和libz。

Solved. Have to load 3 frameworks: libXML, Security and libz.
