使用示例：
CCLOG("Characters: %c %c", 'a', );
CCLOG("Decimals: %d %ld", , 650000L);
CCLOG("Preceding with blanks: %10d", );
CCLOG("Preceding with zeros: %010d", );
CCLOG("Some different radixes: %d %x %o %#x %#o", , , , , );
CCLOG("Floats: %4.2f %.0e %E", 3.1416, 3.1416, 3.1416);
CCLOG("%s","A string");
输出：
