在之前一片文章我们介绍了OC中的内存管理:http://blog.csdn.net/jiangwei0910410003/article/details/41924683,今天我们来介绍两个关键字的使用:@property和@synthesize

一、@property关键字

这个关键字是OC中能够快速的定义一个属性的方式,而且他可以设置一些值,就可以达到一定的效果,比如引用计数的问题

下面来看一下他的使用方法:

//
// Person.h
// 25_Property
//
// Created by jiangwei on 14-10-12.
// Copyright (c) 2014年 jiangwei. All rights reserved.
// #import <Foundation/Foundation.h> @interface User : NSObject{
//NSString *_userName;
//NSString *_passWord;
//...
} //第一步生成_userName属性
//第二步为_userName属性自动生成set/get方法 //property在生成的set方法中,有没有做引用的操作?
//set方法的三种方式:
//第一种方式:
//普通赋值
//一般对象类型的引用操作
//NSString对象类型的引用操作 //第一个位置
//atomic:线程保护的,默认
//nonatomic:线程不保护的 //第二个位置
//assign:直接赋值,默认
//retain:保留对象
//copy:拷贝对象 //第三个位置
//readwrite:生成get/set方法,默认
//readonly:只生成get方法
@property NSString *userName;

@end

还记得我们之前定义属性的时候,在{...}中进行定义,而且定义完之后还有可能需要实现get/set方法,这里我们直接使用@property关键字进行定义:

@property NSString *userName;

这样定义完之后,我们就可以使用这个属性了:

这样定义的方式之后,这个属性就会自动有set/get方法了

第一步生成_userName属性

第二步为_userName属性自动生成set/get方法

这样定义是不是比以前方便多了

下面再来看一下他还有三个值可以设置:

@property(atomic,retain,readwrite) Dog *dog;

1、第一个位置的值:

atomic:线程保护的,默认

nonatomic:线程不保护的

2、第二个位置的值:

assign:直接赋值,默认

retain:保留对象,内部会自动调用retain方法,引用计数+1

copy:拷贝对象

3、第三个位置的值:

readwrite:生成get/set方法,默认

readonly:只生成get方法

这里来做一个例子:

main.m

//
// main.m
// 25_Property
//
// Created by jiangwei on 14-10-12.
// Copyright (c) 2014年 jiangwei. All rights reserved.
// #import <Foundation/Foundation.h> #import "User.h"
#import "Dog.h" //当一个类中有很多个属性的时候,那么我们需要手动的编写他们的set/get方法
//这样就比较费时,所以这时候就可以使用@property
int main(int argc, const char * argv[]) { User *user = [[User alloc] init];
Dog *dog = [[Dog alloc] init];
NSLog(@"count:%ld",[dog retainCount]); [user setDog:dog]; NSLog(@"count:%ld",[dog retainCount]); return 0;
}

运行结果:

二、@synthesize关键字

//
// Person.m
// 25_Property
//
// Created by jiangwei on 14-10-12.
// Copyright (c) 2014年 jiangwei. All rights reserved.
// #import <Foundation/Foundation.h>
#import "User.h" //有时候我们不想定义属性为_开头的
//这时候我们就可以使用@synthesize,来修改我们想要的属性名 //这时候属性_userName变成了$userName @implementation User
@synthesize userName = $userName; @end

因为我们使用@property定义属性之后,如果我们想修改这个属性的名称,就可以使用@synthesize关键字来对属性名称进行修改

@synthesize userName = $userName;

总结

这一篇主要介绍了两个关键字的使用,@property和@synthesize,特别是@property关键字,后面定义属性的时候几乎就是用它了,非常方便
