@interface Dog : NSObject

//{

//    NSString *_name;

//    NSInteger _age;

//}



- (id)init;



//方法一

//- (NSString *)name;

//- (NSInteger)age;

//

//- (void)setName:(NSString *)name;

//- (void)setAge:(NSInteger)age;



//方法二:

//@property 关键字展开setter getter方法的声明



//- (NSString *)name;

//- (void)setName:(NSString *)name;

//@property NSString *name;



//- (NSInteger)age;

//- (void)setAge:(NSInteger)age;

//@property NSInteger age;



//方法三

//展开setter getter方法的声明及synthesize语句

//展开@synthesize name = _name;

//@synthesize age = _age;



@property NSString *name;

@property NSInteger age;

//@synthesize 关键字展开 setter getter方法的实现
