IOS 集成微信支付功能的实现方法
IOS集成微信支付功能的实现方法
第一步:集成微信的SDK
https://pay.weixin.qq.com/wiki/doc/api/index.html
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);
}];
}
