Xcode 重复符号_cpxyzcocos2D-x v3.1

这些代码在iOS模拟器上编译并运行良好。 当我在targetr->Build Settings->Other Linker标志中添加-ObjC或-all_load，然后编译并运行时，xcode会给出以下错误：

我添加了ad SDK和一些SDK require-ObjC和-all_加载标志。正在删除-所有加载修复了该问题。因此，任何类似的问题都可以忽略ad SDK教程中的所有加载标志

为什么要添加这些标志？您的问题被标记为cocos2d-x。我添加了ad SDK，一些SDK需要-ObjC和-all_加载标志。正在删除-所有加载修复了该问题。
