解决Xcode打印不完整的问题

#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

或

.h直接添加

#define NSLog(FORMAT, ...) fprintf(stderr, "%s:%zd    %s", [[[NSString stringWithUTF8String: __FILE__] lastPathComponent] UTF8String], __LINE__, [[NSString stringWithFormat: FORMAT, ## __VA_ARGS__] UTF8String]);
