ios10 nslog打印不全的bug

解决方法：使用prinf()替代nslog

#ifdef DEBUG
#define KSLog(format, ...) printf("class: <%p %s:(%d) > method: %s \n%s\n", self, [[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String], __LINE__, __PRETTY_FUNCTION__, [[NSString stringWithFormat:(format), ##__VA_ARGS__] UTF8String] )
#else
#define KSLog(format, ...)
#endif
