static variable 在某个类中声明一个static 静态变量, 其他类中想使用它或者修改它不用new 这个对象 ,直接使用它的类名方可直接拿到这个静态变量的对象,遍可以在其他类中任意修改这个变量的数值。 在Objective-C 的语法中声明后的static静态变量在其他类中是不能通过类名直接访问的,它的作用域只能是在声明的这个.m...

Adding "inline" to a "static" function with a "static" variable inside: inline static void doSomething() { static int value ; } has the same result than not adding this "inline" keyword, as far as the static variable inside is concerned. So the behaviour of VC++ is correct, and yo...
