解决方案：自定义宏，通过fprintf函数打印log,完美解决!
#ifdef DEBUG #define NSLog(FORMAT, ...) fprintf(stderr, "%s:%zd\t%s\n", [[[NSString stringWithUTF8String: __FILE__] lastPathComponent] UTF8String], __LINE__, [[NSString stringWithFormat: FORMAT, ## __VA_ARGS__] UTF8String]); #else #define NSLog(FORMAT, ...) nil #endif
