IOS集成微信支付功能的实现方法
第一步:集成微信的SDK

点击进入
下载对应SDK或示例,最后可以看看示例程序
第二步:在Xcode中填写微信开放平台申请的Appid
Xcode>info>URLTypes 中新建加入Appid
第三步:在Appdelegate.m中注册微信支付和回调
#import"WXApi.h" 添加代理 WXApiDelegate -(BOOL)application:(UIApplication*)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions{ //Overridepointforcustomizationafterapplicationlaunch. //self.window.backgroundColor=[UIColorclearColor]; //微信支付注册 [WXApiregisterApp:PAY_WEIXIN_ID]; returnYES; } //ios9.0以上系统版本回调 -(BOOL)application:(UIApplication*)appopenURL:(NSURL*)urloptions:(NSDictionary*)options { //微信 if([url.schemeisEqualToString:PAY_WEIXIN_ID]){ [WXApihandleOpenURL:urldelegate:(id )self]; } //支付宝 if([url.schemeisEqualToString:@"SearchPigeonWorld"]){ //跳转支付宝钱包进行支付,处理支付结果 [[AlipaySDKdefaultService]processOrderWithPaymentResult:urlstandbyCallback:^(NSDictionary*resultDic){ if([self.appMyDelegaterespondsToSelector:@selector(payCenterWeixinOnResultWith:)]){ [self.appMyDelegatepayCenterWeixinOnResultWith:[resultDic[@"resultStatus"]intValue]==9000?YES:NO]; } }]; } returnYES; } //支付成功时调用,回到第三方应用中ios9.0以下系统版本回调 -(BOOL)application:(UIApplication*)applicationopenURL:(NSURL*)urlsourceApplication:(NSString*)sourceApplicationannotation:(id)annotation { //微信 if([url.schemeisEqualToString:PAY_WEIXIN_ID]) { [WXApihandleOpenURL:urldelegate:(id )self]; } //支付宝 if([url.hostisEqualToString:PAY_ALIPAY_appID]){ //跳转支付宝钱包进行支付,处理支付结果 [[AlipaySDKdefaultService]processOrderWithPaymentResult:urlstandbyCallback:^(NSDictionary*resultDic){ if([self.appMyDelegaterespondsToSelector:@selector(payCenterWeixinOnResultWith:)]){ [self.appMyDelegatepayCenterWeixinOnResultWith:[resultDic[@"resultStatus"]intValue]==9000?YES:NO]; } }]; } returnYES; } /** 微信自己的结果返回方法 @paramresp返回结果状态 */ -(void)onResp:(BaseResp*)resp { if([respisKindOfClass:[PayRespclass]]){ BOOLisPaySuccess=NO; switch(resp.errCode){ caseWXSuccess: isPaySuccess=YES; break; caseWXErrCodeUserCancel: isPaySuccess=NO; break; caseWXErrCodeSentFail: isPaySuccess=NO; break; caseWXErrCodeAuthDeny: isPaySuccess=NO; break; default: isPaySuccess=NO; break; } if([self.appMyDelegaterespondsToSelector:@selector(payCenterWeixinOnResultWith:)]){ [self.appMyDelegatepayCenterWeixinOnResultWith:isPaySuccess]; } } }
第四步:在使用微信的地方调用支付方法
#pragmamark2.2.14(10)使用微信进行付款,获取微信加密信息 -(void)getWebResponsePayWeixinInfo{ NSDictionary*parameters=@{@"key":appDelegate.userKeyString, @"foundRecordId":[self.payInfoDictobjectForKey:@"foundRecordId"]}; [MBProgressHUDshowMessage:@""]; [WebDataResponseInterfaceSessionManagerPostWebDataWithApi:WEBInterFace_Good_CreateWeiXinPayOrderandParameters:parametersandSuccess:^(idsuccessObject){ MYLOG(@"%@",successObject); [MBProgressHUDhideHUD]; if([successObject[@"status"]isEqualToString:@"success"]){ successObject=[successObjectobjectForKey:@"value"]; //微信支付 //需要创建这个支付对象 PayReq*req=[[PayReqalloc]init]; //由用户微信号和AppID组成的唯一标识,用于校验微信用户 req.openID=successObject[@"appid"]; //商家id,在注册的时候给的 req.partnerId=[successObjectobjectForKey:@"partnerid"]; //预支付订单这个是后台跟微信服务器交互后,微信服务器传给你们服务器的,你们服务器再传给你 req.prepayId=[successObjectobjectForKey:@"prepayid"]; //根据财付通文档填写的数据和签名 //这个比较特殊,是固定的,只能是即req.package=Sign=WXPay req.package=[successObjectobjectForKey:@"package"]; //随机编码,为了防止重复的,在后台生成 req.nonceStr=[successObjectobjectForKey:@"noncestr"]; //这个是时间戳,也是在后台生成的,为了验证支付的 req.timeStamp=[[successObjectobjectForKey:@"timestamp"]doubleValue]; //这个签名也是后台做的 req.sign=[successObjectobjectForKey:@"sign"]; //发送请求到微信,等待微信返回onResp [WXApisendReq:req]; }else{ [MBProgressHUDshow:[successObjectobjectForKey:@"value"]icon:nilview:self.view]; } }andFailure:^(NSError*error){ [MBProgressHUDhideHUD]; MYLOG(@"error:%@",error); }]; }
