#git subtree 的用法

假如有一个iOS的项目,我用到了很多外部的库,如AFNetworking,我怎么把它集成进来呢?

##通过submodule的方法

把这个项目追加到自己是项目中:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

template<typename T>
class Singleton
{
public:
  static T &instance()
  {
    if (!instance)
      instance_ = new T;
    return *instance_;
  }
