【问题描述】：
在我的 iOS 项目中，正在使用库 libbaidumapapi.a 和 libPayPalMPL.a。
项目可以正确构建，但它会在运行时发出异常信号。
在调试问题的时候，发现是因为库libPayPalMPL.a调用了库libbaidumapapi.a里面的XMLFreeDoc函数，但是应该是调用了xml2动态库里面的XMLFreeDoc函数。
我没有这两个库的源代码。当我检查libbaidumapapi.a 时，我发现它与minixml.o 和deflate.o 一起使用XMLFreeDoc 归档，并且放气可能与libPayPalMPL.a 冲突。
libPayPalMPL.a 库依赖于两个动态库：xml2 和 zlib。
我可以解决这个崩溃问题吗？我在libbaidumapapi.a 之前已经使用了force_load。
