//1 手动解析,就是每个属性按顺序赋值,笨重切费时
/*2 KVC ...简单介绍一下KVC,就是key value Codeing的意思,翻译一下就是键值编码,苹果官方为我们能用到的包括NSObject NSArray等常见的类都做了一个叫NSKeyValueCoding的分类,而KVC的操作方法由NSKeyValueCoding协议提供,也就是说我们用到的Objc都是支持KVC的.
再说一下KVC的作用,主要目的就是给对象赋值和取值,当然不单单是给你能看得到的属性,iOS在编译阶段会将一个类的属性及其对应的值都放进内存,可以通过runtime获得到,具体方法下面已经提供,所以KVC能解决官方没有提供接口的某些属性的值,例如UISwitch的颜色等.
