苹果的app store上有许多的软件，有的重量级的大作是直接挂个价钱就上架，有的是先提供免费的试玩版，满意再买正式版，其中有些则是不收费，但会放一些广告在里面。这些软件的开发者有的是真的佛心，有的是纯练功，不过置入广告来赚取一些生活费并没什么对错的问题，毕竟大家也都是要过日子。放个广告上来只要不影响整个app的使用也没应该没什么大碍，毕竟这些开发者也还是需要一些”动力”才能继续帮大家开发更好用的软件。
 
你也许会好奇放这个广告是能赚什么钱，在不久前有个故事，就]]>https://blog.youkuaiyun.com/levellee/article/details/6183014https://blog.youkuaiyun.com/levellee/article/details/6183014levelleeSun, 13 Feb 2011 22:53:00 +0800数据和操作
传统的编程语言通常划分成两个部分—数据和对数据的操作。数据是静态的，不变的，除非通过操作来改变它。对数据操作的函数并不保留上一次操作时数据的状态，它们的作用仅体现在操作数据上。
 
很明显，这种划分是基于计算机的工作方式，所以您很难忽视它。和无处不在的原料和能量以及名词和动词的划分一样，它构成了程序的本质。从某种意义上说，所有的程序员—即使是面向对象的程序员—都是工作在数据结构之上，他们的程序也会使用和定义函数来操作数据。

 NSString 是NSObject的子类
NSString是不可变的，意思是他声明的对象我们不可以改变，如果要改变，可以使用它的子类：NSMutableString
 
你可以使用类方法：stringWithCapacity来创建一个新的NSMutableString,声明如下：


*  (id) stringWithCapacity: (unsigned) capacity:
