看惯了什么tempSelf weakSelf，来点高大的

#define weakify(...) \    rac_keywordify \    metamacro_foreach_cxt(rac_weakify_,, __weak, __VA_ARGS__)#define unsafeify(...) \    rac_keywordify \    metamacro_foreach_cxt(rac_weakify_,, __unsafe_unretained, __VA_ARGS__)#define strongify(...) \    rac_keywordify \    _Pragma("clang diagnostic push") \    _Pragma("clang diagnostic ignored \"-Wshadow\"") \    metamacro_foreach(rac_strongify_,, __VA_ARGS__) \    _Pragma("clang diagnostic pop")#if DEBUG#define rac_keywordify autoreleasepool {}#else#define rac_keywordify try {} @catch (...) {}#endif

使用方法，进block前wesk一下，进block后strong一下

等等，有多个对象要处理这样用

 

把名字换下，更具个性，self任意用，赶紧试试吧
