KVC总结

标准set

Person * person=[[Personalloc]init];

person.name=@"张三";

Dog * dog=[[Dogalloc]init];

dog.name=@"旺财";

person.dog=dog;

KVC

Person * person=[[Personalloc]init];

[personsetValue:@"张三"forKeyPath:@"name"];

Dog * dog=[[Dogalloc]init];

[personsetValue:dogforKey:@"dog"];

[personsetValue:@"旺财"forKeyPath:@"dog.name"];

forKey 和forKeyPath区别

1.forKeyPath包含所搜forKey的功能

2.forKeyPath 可以使用内部的点语法，层层访问内部属性

3.注意:key值一定要在属性中找到
