第一步:內建微信的SDK
https://pay.weixin.qq.com/wiki/doc/api/index.html
點選進入
下載下傳對應SDK或示例,最後可以看看示例程式
第二步:在Xcode中填寫微信開放平台申請的Appid
Xcode>info>URL Types 中建立加入Appid
第三步:在Appdelegate.m 中注冊微信支付 和回調
#import "WXApi.h"
添加 代理
WXApiDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
//self.window.backgroundColor = [UIColor clearColor];
// 微信支付注冊
[WXApiregisterApp:PAY_WEIXIN_ID];
returnYES;
}
// ios 9.0以上系統版本回調
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
// 微信
if ([url.schemeisEqualToString:PAY_WEIXIN_ID]) {
[WXApihandleOpenURL:url delegate:(id<WXApiDelegate>)self];
}
// 支付寶
if ([url.schemeisEqualToString:@"SearchPigeonWorld"]) {
//跳轉支付寶錢包進行支付,處理支付結果
[[AlipaySDKdefaultService] processOrderWithPaymentResult:urlstandbyCallback:^(NSDictionary *resultDic) {
if ([self.appMyDelegaterespondsToSelector:@selector(payCenterWeixinOnResultWith:)]) {
[self.appMyDelegatepayCenterWeixinOnResultWith:[resultDic[@"resultStatus"]intValue] ==9000 ? YES :NO];
}
}];
}
returnYES;
}
//支付成功時調用,回到第三方應用中 ios 9.0以下系統版本回調
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
// 微信
if ([url.schemeisEqualToString:PAY_WEIXIN_ID])
{
[WXApihandleOpenURL:url delegate:(id<WXApiDelegate>)self];
}
// 支付寶
if ([url.hostisEqualToString:PAY_ALIPAY_appID]) {
//跳轉支付寶錢包進行支付,處理支付結果
[[AlipaySDKdefaultService] processOrderWithPaymentResult:urlstandbyCallback:^(NSDictionary *resultDic) {
if ([self.appMyDelegaterespondsToSelector:@selector(payCenterWeixinOnResultWith:)]) {
[self.appMyDelegatepayCenterWeixinOnResultWith:[resultDic[@"resultStatus"]intValue] ==9000 ? YES :NO];
}
}];
}
returnYES;
}
- (void)onResp:(BaseResp*)resp
{
if([respisKindOfClass:[PayRespclass]]){
BOOL isPaySuccess =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:在使用微信的地方調用支付方法
#pragma mark 2.2.14(10)使用微信進行付款,擷取微信加密資訊
- (void)getWebResponsePayWeixinInfo {
NSDictionary *parameters =@{@"key" :appDelegate.userKeyString,
@"foundRecordId" : [self.payInfoDictobjectForKey:@"foundRecordId"]};
[MBProgressHUDshowMessage:@""];
[WebDataResponseInterfaceSessionManagerPostWebDataWithApi:WEBInterFace_Good_CreateWeiXinPayOrderandParameters:parameters andSuccess:^(id successObject) {
MYLOG(@"%@", successObject);
[MBProgressHUDhideHUD];
if ([successObject[@"status"]isEqualToString:@"success"]) {
successObject = [successObject objectForKey:@"value"];
// 微信支付
//需要建立這個支付對象
PayReq *req = [[PayReqalloc] init];
//由使用者微信号和AppID組成的唯一辨別,用于校驗微信使用者
req.openID = successObject[@"appid"];
// 商家id,在注冊的時候給的
req.partnerId = [successObjectobjectForKey:@"partnerid"];
// 預支付訂單這個是背景跟微信伺服器互動後,微信伺服器傳給你們伺服器的,你們伺服器再傳給你
req.prepayId = [successObjectobjectForKey:@"prepayid"];
// 根據财付通文檔填寫的資料和簽名
//這個比較特殊,是固定的,隻能是即req.package = Sign=WXPay
req.package = [successObjectobjectForKey:@"package"];
// 随機編碼,為了防止重複的,在背景生成
req.nonceStr = [successObjectobjectForKey:@"noncestr"];
// 這個是時間戳,也是在背景生成的,為了驗證支付的
req.timeStamp = [[successObjectobjectForKey:@"timestamp"]doubleValue];
// 這個簽名也是背景做的
req.sign = [successObjectobjectForKey:@"sign"];
//發送請求到微信,等待微信傳回onResp
[WXApisendReq:req];
} else {
[MBProgressHUDshow:[successObject objectForKey:@"value"]icon:nilview:self.view];
}
} andFailure:^(NSError *error) {
[MBProgressHUDhideHUD];
MYLOG(@"error: %@", error);
}];
}
