va_arg(argList,id)：返回参数列表中指针arg_ptr所指的参数，返回类型为type，并使指针arg_ptr指向参数列表中下一个参数。你新建了一个argList，拿出指针给NSString *arg赋值会报bad_ACCESS错误，换成id arg试试 因为
char string[256]; va_start(ap,fmt);//将第一个可变参数的地址付给ap,即ap指向可变参数列表的开始 //ch = va_arg( ap, char *);//取出ap里面的值,即第一个可变参数,char *根据实际传入的参数类型改变,调用va_arg后ap自增; //ch1 = va_arg( ap, char);//取出ap里面的值,即第二个可变参数,...
