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：
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 @end
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）
#import <Foundation/Foundation.h> //支付宝SDK #import <AlipaySDK/AlipaySDK.h> //微信接口 #import <WXApi.h> //银联接口 #import "UPPaymentControl.h" /** 枚举：列出第三方支付方式 */ typedef NS_ENUM(NSInteger, PayType) { kPayTypeWXPay, // 微信支付 kPayTypeALiPay, // 支付宝支付 kPayTypeUNPay // 银联支付 }; /** IOAPayRequestModel:第三方支付需要的参数 */ @interface IOAPayRequestModel: NSObject @property (nonatomic, assign) PayType payType; /** 支付宝和银联-后台返回是字符串类型----支付宝和银联使用此方式 */ @property (nonatomic, copy) NSString *payString; @property (nonatomic, copy) NSString *appScheme; // 根据设置的paytype设置 /** 微信-后台返回是字典类型--- 微信使用此方式 */ @property (nonatomic, strong) NSDictionary *userInfo; @end /** 第三方支付接口返回的数据--- */ @interface IOAPayResponseModel: NSObject @property (nonatomic, assign) PayType payType; //result和userInfo信息判断支付结果--（支付成功、支付失败、支付取消等） @property (nonatomic, assign) NSInteger result; @property (nonatomic, strong) NSDictionary *userInfo; @end @interface IOAPayApi : NSObject //支付返回的回调方法 @property (nonatomic, copy) void (^callback)(IOAPayResponseModel *response); //支付请求model ----IOAPayRequestModel---第三方支付需要的参数 @property (nonatomic, strong) IOAPayRequestModel *payRequestModel; //单例方法 + (instancetype)defaultPayManager; // 是否安装了客户端 - (BOOL)isPayAppInstalled:(PayType)payType; // 支付 - (void)pay:(IOAPayRequestModel *)payRequestModel callback:(void (^)(IOAPayResponseModel *response))callback; // 支付回调 - (void)payCallbackWithUrl:(NSURL *)url; @end

3.此时方法就开始封装好了，可以在需要的地方直接使用（弹框已作出）
- (void)alipay{ [self startProgress]; self.requestModel.pay_type = @"alipayMobile"; //自己后台的接口---拿到后台返回的数据作为第三方接口的参数 [self.viewModel requestCartSettlePay:self.requestModel callback:^(IOAResponse *response) { dispatch_async(dispatch_get_main_queue(), ^{ [self stopProgress]; if (response.success) { NSString *appScheme = @"IOAAlipaySDK"; self.payRequestModel.payString = response.responseObject; self.payRequestModel.payType = 1; self.payRequestModel.appScheme = appScheme; //第三方接口调用（封装） [[IOAPayApi defaultPayManager] pay:self.payRequestModel callback:^(IOAPayResponseModel *response) { dispatch_async(dispatch_get_main_queue(), ^{ NSDictionary *userInfo = response.userInfo; if (![userInfo[@"resultStatus"] isEqualToString:@"9000"]) { //进入待付款界面(支付失败或者支付取消等) [self pushWait]; }else{ //进入订单列表界面（支付成功） [self pushList]; } }); }]; }else{ [self.view makeToast:@"支付失败"]; } }); }]; }
4.重磅来临（一些人弹框没有作出，可以直接拷贝下面代码）
新建控制器控制弹框.h文件中

举例方法
利用请求的数据进行赋值传值。
IOAOrderBaseModel *dataSourceModel = self.dataSource[indexPath.section]; IOAOrderSelectAbleItemModel *itemModel = (IOAOrderSelectAbleItemModel *) dataSourceModel.items[row]; IOAPayViewController *vc = [IOAPayViewController show:^(NSInteger atIndex) { IOAPayItemModel *payItem = itemModel.items[atIndex]; itemModel.selectedIndex = atIndex; weakSelf.requestModel.pay_type = payItem.code; weakSelf.payItem = payItem; [weakSelf.tableView reloadSections:[NSIndexSet indexSetWithIndex:section] withRowAnimation:UITableViewRowAnimationNone]; }]; [vc setupItems:self.confirmOrderInfo.payment_list]; [vc setupTitle:@"请选择支付方式"];
最后的举例方法并不是所有的适用，对于上面1.2.3还是可以直接拿过去使用，这些都是原创，如果第一次接入还是希望各位读者读一下上篇文章，集成的整个过程，链接为http://www.cnblogs.com/guohai-stronger/p/8971508.html，这个代码的整个demo，我会尽快上传到github，谢谢！祝贺大家过一个愉快的劳动节！！！
