[置顶] iOS支付（包括支付宝、微信、银联）封装

 

前言

最近在学习构架，感觉到构架的魅力，自己用构架思想封装了一个支付集合，欢迎使用！

开发环境

1、xcode 8以上

2、iOS 7.0以上

支付SDK的集成

1、支付宝

参照博客 支付宝支付集成 ，里面很详细这里就不多说了。

2、微信支付

参照博客 微信支付集成  

3、银联支付

银联支付要比支付宝及微信要简单

 参照  银联支付集成

工程目录结构



依赖库目录



工厂模式

1、代理统一抽象接口

#import <UIKit/UIKit.h>

#import "TXP_Charge.h"

#import "TXP_PayComplation.h"

//代理模式->目标接口：支付接口

@protocol TXP_IPay <NSObject>

-(void)payWithCharge:(TXP_Charge*)charge controller:(UIViewController*)controller scheme:(NSString*)scheme withComplation:(TXP_PayComplation)complation;

//业务方法二：需要处理支付结果回调(9.0以前回调)

- (BOOL)handleOpenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication withComplation:(TXP_PayComplation)complation;

//业务方法三：需要处理支付结果回调(9.0以后回调)

- (BOOL)handleOpenURL:(NSURL *)url withComplation:(TXP_PayComplation)complation;

@end
2、支付宝具体实现类（需要遵守自己TXP_IPay的抽象协议）

@interface TXP_ALiPay ()

@property (nonatomic)TXP_PayComplation complation;

@end

@implementation TXP_ALiPay

- (instancetype)init{

    self = [superinit];

    if (self) {

    }

    return
self;

}

- (void)payWithCharge:(TXP_Charge*)charge controller:(UIViewController *)controller scheme:(NSString *)scheme withComplation:(TXP_PayComplation)complation{

    

    if (complation) {

        _complation = complation;

    }

    [[AlipaySDK defaultService]payOrder:charge.orderNofromScheme:scheme
callback:^(NSDictionary *resultDic) {

        NSString * state = [NSStringstringWithFormat:@"%@",resultDic[@"resultStatus"]];

        if ([state
isEqualToString:@"9000"]) {

           _complation(STR_PAY_SUCCESS,nil);

        }

        else if ([stateisEqualToString:@"6001"])

        {

             _complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorActivation]);

            

        }else

        {

            _complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorActivation]);

        }

    }];

}

//业务方法二：需要处理支付结果回调(9.0以前回调)

- (BOOL)handleOpenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication withComplation:(TXP_PayComplation)complation{

    if (complation) {

        _complation = complation;

    }

    if ([url.hostisEqualToString:@"safepay"]) {

        //跳转支付宝钱包进行支付，处理支付结果

        [[AlipaySDKdefaultService]
processOrderWithPaymentResult:urlstandbyCallback:^(NSDictionary *resultDic) {

            //            NSLog(@"result = %@",resultDic);

            NSString * state = [NSStringstringWithFormat:@"%@",resultDic[@"resultStatus"]];

            if ([state
isEqualToString:@"9000"]) {

                [[NSNotificationCenterdefaultCenter]
postNotificationName:@"judgePayStatu"object:self];

            }  else
if ([state isEqualToString:@"6001"]){

                [[NSNotificationCenterdefaultCenter]
postNotificationName:@"cancelPayment"object:self];

            }

        }];

    }

    return
YES;

}

//业务方法三：需要处理支付结果回调(9.0以后回调)

- (BOOL)handleOpenURL:(NSURL *)url withComplation:(TXP_PayComplation)complation{

    

    return [selfhandleOpenURL:url
sourceApplication:nilwithComplation:complation];

}

3、微信具体实现类（需要遵守自己TXP_IPay的抽象协议）

@interface
TXP_WxPay ()<WXApiDelegate>

@property (nonatomic)TXP_PayComplation complation;

@end

@implementation TXP_WxPay

- (instancetype)init{

    self = [superinit];

    if (self) {

        BOOL isSuccess = [WXApiregisterApp:@"这里填写注册key"];

        if (isSuccess) {

            NSLog(@"注册成功！");

        }

    }

    return
self;

}

//业务方法一：需要调用微信支付接口(唤醒微信支付)

-(void)payWithCharge:(TXP_Charge*)charge controller:(UIViewController*)controller scheme:(NSString*)scheme withComplation:(TXP_PayComplation)complation{

    _complation = complation;

    NSString* timeStamp = [NSStringstringWithFormat:@"%@",[charge.credentialobjectForKey:@"timestamp"]];

    PayReq *request = [[PayReqalloc]
init];

    request.partnerId = [charge.credentialobjectForKey:@"partnerid"];

    request.prepayId= [charge.credentialobjectForKey:@"prepayid"];

    request.package =
@"Sign=WXPay";

    request.nonceStr= [charge.credentialobjectForKey:@"noncestr"];

    request.timeStamp= [timeStamp
intValue];

    request.sign= [charge.credentialobjectForKey:@"sign"];

    [WXApi sendReq:request];

}

//业务方法二：需要处理支付结果回调(9.0以前回调)

- (BOOL)handleOpenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication withComplation:(TXP_PayComplation)complation{

    if (complation) {

        _complation = complation;

    }

    return [WXApihandleOpenURL:url
delegate:self];

}

//业务方法三：需要处理支付结果回调(9.0以后回调)

- (BOOL)handleOpenURL:(NSURL *)url withComplation:(TXP_PayComplation)complation{

    return [selfhandleOpenURL:url
sourceApplication:nilwithComplation:complation];

}

-(void)onResp:(BaseResp*)resp{

    if ([resp isKindOfClass:[PayRespclass]]){

        PayResp*response=(PayResp*)resp;

        switch(response.errCode){

            case WXSuccess:

                _complation(STR_PAY_SUCCESS,nil);

                break;

            caseWXErrCodeCommon:

                _complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorUnknownError]);

                break;

            caseWXErrCodeUserCancel:

                _complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorCancelled]);

                break;

            default:

                _complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorCancelled]);

                break;

        }

    }

}

4、银联具体实现类（需要遵守自己TXP_IPay的抽象协议）

@interface
TXP_UnionPay ()

@property (nonatomic)TXP_PayComplation complation;

@end

@implementation TXP_UnionPay

//业务方法一：需要调用银联支付接口(唤醒银联支付)

//银联支付请求处理

- (void)payWithCharge:(TXP_Charge*)charge controller:(UIViewController *)controller scheme:(NSString *)scheme withComplation:(TXP_PayComplation)complation{

    

    _complation = complation;

    dispatch_sync(dispatch_get_main_queue(), ^{

        //需要支付凭证

        NSString* tn = [charge.credentialobjectForKey:@"tn"];

        NSString* unionPaymode = [charge.credentialobjectForKey:@"mode"];

        BOOL isSuccess = [[UPPaymentControldefaultControl]
startPay:tnfromScheme:scheme
mode:unionPaymode
viewController:controller];

        if (!isSuccess) {

            _complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorActivation]);

        }

    });

}

//银联支付回调

//业务方法二：需要处理支付结果回调(9.0以前回调)

- (BOOL)handleOpenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication withComplation:(TXP_PayComplation)complation{

    if (complation) {

        _complation = complation;

    }

    [[UPPaymentControldefaultControl]
handlePaymentResult:urlcompleteBlock:^(NSString *code,NSDictionary
*data) {

        if([code isEqualToString:@"success"]) {

            //结果code为成功时，去商户后台查询一下确保交易是成功的再展示成功

            complation(STR_PAY_SUCCESS,nil);

        }else if([codeisEqualToString:@"fail"]) {

            //交易失败

            complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorUnknownError]);

        }else if([codeisEqualToString:@"cancel"]) {

            //交易取消

            complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorCancelled]);

        }

    }];

    return
YES;

}

//业务方法三：需要处理支付结果回调(9.0以后回调)

- (BOOL)handleOpenURL:(NSURL *)url withComplation:(TXP_PayComplation)complation{

    

    return [selfhandleOpenURL:url
sourceApplication:nilwithComplation:complation];

}

@end

单例模式调用方法类

+(instancetype)sharedEngine{

    static TXP_PayEngine* payEngine;

    static dispatch_once_t onceToken;

    dispatch_once(&onceToken, ^{

        payEngine = [[self
alloc] init];

    });

    return payEngine;

}

- (instancetype)init{

    self = [superinit];

    if (self) {

        [selfregisterChannel];

    }

    return
self;

}

//注册支付渠道

-(void)registerChannel{

    _channelDic =
@{PAY_UNIONPAY : [[TXP_UnionPayalloc]
init],

                    PAY_WXPAY : [[TXP_WxPayalloc]
init],

                    PAY_ALIPAY: [[TXP_ALiPayalloc]init]

                    };

}

//处理支付

-(void)payWithCharge:(TXP_Charge*)charge controller:(UIViewController*)controller scheme:(NSString*)scheme withComplation:(TXP_PayComplation)complation{

    

    //验证Controller是否为空

    if (controller ==
nil) {

        complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorViewControllerIsNil]);

        return;

    }

    

    _channel = charge.channel;

   

    id<TXP_IPay> pay = [_channelDicobjectForKey:charge.channel];

    if (pay == nil) {

        complation(nil,[TXP_PayErrorUtilscreate:TXP_PayErrorInvalidChannel]);

        return;

    }

    

    [pay payWithCharge:charge
controller:controller scheme:scheme
withComplation:complation];

}

//处理回调

- (BOOL)handleOpenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication withComplation:(TXP_PayComplation)complation{

    return [[_channelDicobjectForKey:_channel]handleOpenURL:url
sourceApplication:sourceApplication
withComplation:complation];;

}

- (BOOL)handleOpenURL:(NSURL *)url withComplation:(TXP_PayComplation)complation{

    return [[_channelDicobjectForKey:_channel]handleOpenURL:url
sourceApplication:nilwithComplation:complation];

}

调用测试

@implementation ViewController

- (void)viewDidLoad {

    [superviewDidLoad];

     ViewController *
__weak weakSelf = self;

    TXP_Charge *charge = [[TXP_Chargealloc]init];//此model配置从服务器获得的参数

    charge.channel =
PAY_ALIPAY; //支付类型

    [[TXP_PayEnginesharedEngine]
payWithCharge:chargecontroller:weakSelf
scheme:@"TXPPayDemo"withComplation:^(NSString *result,TXP_PayError
*error) {

        //回调

        if (error) {

            //出现了异常

            NSLog(@"%@",[errorgetMsg]);

        }else{

            //支付成功

            NSLog(@"支付成功!");

        }

    }];

}

AppDelegate类里只需一句代码

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {

   

    return [[TXP_PayEnginesharedEngine]
handleOpenURL:urlwithComplation:nil];

}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {

    return [[TXP_PayEnginesharedEngine]
handleOpenURL:urlwithComplation:nil];

}
