CFSDN坚持开源创造价值，我们致力于搭建一个资源共享平台，让每一个IT人在这里找到属于你的精彩世界.

这篇CFSDN的博客文章iOS支付宝、微信、银联支付集成封装调用（下）由作者收集整理，如果你对这篇文章有兴趣，记得点赞哟.

一.越来越多的app增加第三方的功能，可能app有不同的页面但调用相同的支付方式，例如界面如下:

iOS支付宝、微信、银联支付集成封装调用（下）

这两个页面都会使用第三方支付支付：（微信，支付宝，银联）如果在每一个页面都直接调用第三方支付的接口全部代码，显然并不是很合适，更何况，可能一个app并不止两个入口。所以封装还是很有必要的.

1.新建model：-------后台返回支付方式的列表json 。

#import <foundation/foundation.h>
 
@interface ioapayitemmodel : nsobject
 
//name:代表是支付宝，微信，银联或者余额等
@property (nonatomic, copy) nsstring *name;
//icon:代表是支付方式的图片
@property (nonatomic, copy) nsstring *icon;
//code:代表支付方式的唯一标识
@property (nonatomic, copy) nsstring *code;
//paytype:代表支付类型（自己确定的）
@property (nonatomic, assign) nsinteger paytype;
@end

#import "ioapayitemmodel.h"
@implementation ioapayitemmodel

2.封装第三方支付接口以及回调接口-----直接上源代码----会有解释（相信大家的能力，肯定能看懂） 。
