- 一句话集成微信支付,支付宝支付以及内购
可以在github上下载的工具类
- 如何使用
1.将工具类拖入工程
2.AppDelegate代码如下:
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [[XNPayManager sharedPayManager] handleOpenURL:url];
}
// NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
return [[XNPayManager sharedPayManager] handleOpenURL:url];
}
3.在使用的地方调起微信或者支付宝
- 支付宝
TIPS：拼装参数应在商户服务端完成，商户服务端直接将组装和签名后的请求串orderString传给客户端，客户端直接传给SDK发起请求。文档和Demo是为了示例效果在客户端实现。所以我们项目中应该按照次操作
// params应该是由后台返回的
[[XNPayManager sharedPayManager] ALIPayWithPayParams: params success:^(PayCode code) {
// 成功业务逻辑
DLog(@"成功");
} failure:^(PayCode code) {
// 失败业务逻辑
DLog(@"失败");
}]
- 微信支付
// dict应该是由后台返回的
[[XNPayManager sharedPayManager] WXPayWithPayDict: dict success:^(PayCode code) {
// 成功业务逻辑
DLog(@"成功");
} failure:^(PayCode code) {
// 失败业务逻辑
DLog(@"成功");
}];
- 内购
//productId 产品唯一标示
[[XNPayManager sharedPayManager] requestProductData: productId success:^(PayCode code) {
// 成功业务逻辑
} failure:^(PayCode code) {
// 失败业务逻辑
}];
- 详细代码
在封装的代码中没有使用通知,因为通知是全局的,然后在项目中出现了一下问题,比如:待支付订单->订单详情 这两个页面都有支付的操作.如果使用通知:这两个控制器支付成功\失败的业务逻辑就会冲突
1.声明支付单例
+ (instancetype)sharedPayManager {
static dispatch_once_t onceToken;
static XNPayManager *instance;
dispatch_once(&onceToken, ^{
instance = [[XNPayManager alloc] init];
});
return instance;
}
2.自定义支付状态码,其实也可以不用定义
/**
支付状态码
*/
typedef NS_ENUM(NSInteger, PayCode) {
WXSUCESS = 1001, /**成功*/
WXERROR = 1002, /**失败*/
WXSCANCEL = 1003, /**取消*/
ALIPAYSUCESS = 1101, /**支付宝支付成功*/
ALIPAYERROR = 1102, /**支付宝支付错误*/
ALIPAYCANCEL = 1103, /**支付宝支付取消*/
APPSTOREPAYSUCESS = 1201, /**内购支付成功*/
APPSTOREPAYERROR = 1201, /**内购支付成功*/
APPSTOREPAYCANCEL = 1201, /**内购支付成功*/
};
3.微信支付
/**
微信支付
@param dict 微信订单字典(全部由后台拼接好给iOS端)
@param successBlock 成功的回调
@param failBolck 失败的回调
*/
- (void)WXPayWithPayDict:(NSDictionary *)dict
success:(void(^)(PayCode code)) successBlock
failure:(void(^)(PayCode code)) failBolck {
self.successBlock = successBlock;
self.failBolck = failBolck;
NSString *strMsg = nil;
//1. 判断是否安装微信
if (![WXApi isWXAppInstalled]) {
NSLog(@"您尚未安装\"微信App\",请先安装后再返回支付");
strMsg = @"您尚未安装\"微信App\",请先安装后再返回支付";
[self tipMessageAlert:nil message:strMsg];
return;
}
//2.判断微信的版本是否支持最新Api
if (![WXApi isWXAppInstalled]) {
NSLog(@"您微信当前版本不支持此功能,请先升级微信应用");
strMsg = @"您微信当前版本不支持此功能,请先升级微信应用";
[self tipMessageAlert:nil message:strMsg];
return;
}
if (!kDictIsEmpty(dict)) {
//调起微信支付
PayReq *req = [[PayReq alloc]init];
req.openID = dict[@"appid"];
req.partnerId = dict[@"partnerid"];
req.prepayId = dict[@"prepayid"];
req.nonceStr = dict[@"noncestr"];
req.timeStamp = [dict[@"timestamp"] intValue];
req.package = @"Sign=WXPay";
req.sign = dict[@"sign"];
[WXApi sendReq:req];
}
}
#pragma mark - WXApiDelegate
//支付结果回调
/// - see [支付结果回调](https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=8_5)
- (void)onResp:(BaseResp *)resp {
NSString *strMsg = [NSString stringWithFormat:@"errcode:%d",resp.errCode];
//回调中errCode值列表：
// 0 成功 展示成功页面
//-1 错误 可能的原因：签名错误、未注册APPID、项目设置APPID不正确、注册的APPID与设置的不匹配、其他异常等
//-2 用户取消 无需处理。发生场景：用户不支付了，点击取消，返回APP
if ([resp isKindOfClass:[PayResp class]]) {
// 支付返回结果,实际支付结果需要去微信服务器端查询
switch (resp.errCode) {
case WXSuccess:{
strMsg = @"支付结果：成功！";
self.successBlock(WXSUCESS);
DLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
break;
}
case WXErrCodeUserCancel:{
strMsg = @"支付结果：取消";
self.failBolck(WXSCANCEL);
DLog(@"支付取消－PayCancel，retcode = %d", resp.errCode);
}
default:{
strMsg = @"支付结果：失败";
self.failBolck(WXERROR);
DLog(@"错误，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
break;
}
}
[self tipMessageAlert:@"支付结果" message:strMsg];
}
}
4.支付宝

*/

NSString *appScheme = @"appScheme";
[[AlipaySDK defaultService] payOrder:params fromScheme:appScheme callback:^(NSDictionary *resultDic) {
DLog(@"我这里是payVC%@",resultDic);
DLog(@"%@",resultDic[@"memo"]);
[self aliPayResult:resultDic];
}];
}
#pragma mark - 支付宝支付结果处理
- (void)aliPayResult:(NSDictionary *)resultDic {
// 返回结果需要通过 resultStatus 以及 result 字段的值来综合判断并确定支付结果。 在 resultStatus=9000,并且 success="true"以及 sign="xxx"校验通过的情况下,证明支付成功。其它情况归为失败。较低安全级别的场合,也可以只通过检查 resultStatus 以及 success="true"来判定支付结果
NSInteger resultStatus = [resultDic[@"resultStatus"] integerValue];
if (resultDic && [resultDic objectForKey:@"resultStatus"]) {
switch (resultStatus) {
case 9000:
[self tipMessageAlert:@"支付结果" message:@"订单支付成功"];
self.successBlock(ALIPAYSUCESS);
break;
case 8000:
[self tipMessageAlert:@"支付结果" message:@"正在处理中"];
self.failBolck(ALIPAYERROR);
break;
case 4000:
[self tipMessageAlert:@"支付结果" message:@"订单支付失败,请稍后再试"];
self.failBolck(ALIPAYERROR);
break;
case 6001:
[self tipMessageAlert:@"支付结果" message:@"已取消支付"];
self.failBolck(ALIPAYCANCEL);
break;

6.单例回调
