ios第三方支付

支付宝

  • 导入SDK
    cocoapods导入pod 'AliPay', 或者手动拖都可以,不详细说。
  • 设置相关配置

  • 调用支付
    在需要调用的界面包含头文件 #import
[[AlipaySDK defaultService] payOrder:@"后台返回给你的值" fromScheme:@"开始设置的url schemes" callback:^(NSDictionary *resultDic) {
                        NSString *resultStatus = resultDic[@"resultStatus"];
                        if ([resultStatus integerValue] == 9000){
                            //网页支付成功
                        }else{
                            //网页支付失败
                        }
                    }];
  • 客户端支付结果回调
    AppDelegate.m中包含头文件 #import
- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    
    if ([url.host isEqualToString:@"safepay"]) {
        //跳转支付宝钱包进行支付,处理支付结果
        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
            if ([resultDic[@"resultStatus"] integerValue] == 9000){
                //成功
              }else {
                //失败
              }
        }];
        return YES;
    }else{
       //这里判断是否发起的请求为微信支付,如果是的话,用WXApi的方法调起微信客户端的支付页面(://pay 之前的那串字符串就是你的APPID,)
        return [WXApi handleOpenURL:url delegate:self];
    }
}

// NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options
{
    if ([url.host isEqualToString:@"safepay"]) {
        //跳转支付宝钱包进行支付,处理支付结果
        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
              if ([resultDic[@"resultStatus"] integerValue] == 9000){
                  //成功
                }else {
                  //失败
                }
        }];
        return YES;
    }else{
        //这里判断是否发起的请求为微信支付,如果是的话,用WXApi的方法调起微信客户端的支付页面(://pay 之前的那串字符串就是你的APPID,)
        return  [WXApi handleOpenURL:url delegate:self];
    }
}

微信

  • 导入SDK
    cocoapods 手动托都可以 不详细说
  • 设置相关配置

    Appdelegate.m 中先注册 包含头文件#import "WXApi.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    self.window.backgroundColor = [UIColor whiteColor];
    //注册
    [WXApi registerApp:@"获取到的appkey" withDescription:@"随意写"];
    return YES;
}
  • 调用支付
    在需要调用支付的界面包含头文件 #import "WXApi.h"
#pragma mark --- 微信
- (void)payWithWeChat:(NSDictionary *)para{
    //字典是是后台返回给你的数据  对应的键值对可能不一样,根据实际情况来写
    NSString *appid = [NSString stringWithFormat:@"%@", para[@"ios"][@"appid"]];
    NSString *partnerId = [NSString stringWithFormat:@"%@", para[@"ios"][@"partnerid"]];
    NSString *prepayid = [NSString stringWithFormat:@"%@", para[@"ios"][@"prepayid"]];
    NSString *package = [NSString stringWithFormat:@"%@", para[@"ios"][@"package"]];
    NSString *nonceStr = [NSString stringWithFormat:@"%@", para[@"ios"][@"noncestr"]];
    NSString *sign = [NSString stringWithFormat:@"%@", para[@"ios"][@"sign"]];
    UInt32 timeStamp = 0;
    if (para[@"ios"][@"timestamp"]) {
        timeStamp = [para[@"ios"][@"timestamp"] unsignedIntValue];
    }
    //需要创建这个支付对象
    PayReq *req   = [[PayReq alloc] 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 = appid;
    // 商家id,在注册的时候给的
    req.partnerId = 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  = 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 = package;
    // 随机编码,为了防止重复的,在后台生成
    req.nonceStr  = nonceStr;
    // 这个是时间戳,也是在后台生成的,为了验证支付的
    req.timeStamp =timeStamp;
    // 这个签名也是后台做的
    req.sign = sign;
    //发送请求到微信,等待微信返回onResp
    [WXApi sendReq:req];
}
#pragma mark - sign加密(一般都是后台加密)
-(NSString *)createMD5SingForPayWithAppID:(NSString *)appid_key partnerid:(NSString *)partnerid_key prepayid:(NSString *)prepayid_key package:(NSString *)package_key noncestr:(NSString *)noncestr_key timestamp:(UInt32)timestamp_key{

    NSMutableString *contentString  =[NSMutableString string];
    NSArray *keys = [signParams allKeys];
    //按字母顺序排序
    NSArray *sortedArray = [keys sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {
        return [obj1 compare:obj2 options:NSNumericSearch];
    }];
    //拼接字符串
    for (NSString *categoryId in sortedArray) {
        if (   ![[signParams objectForKey:categoryId] isEqualToString:@""]
            && ![[signParams objectForKey:categoryId] isEqualToString:@"sign"]
            && ![[signParams objectForKey:categoryId] isEqualToString:@"key"]
            )
        {

    NSString *result = [self md5String:contentString];//md5加密
    return result;
}
- (NSString *)md5String:(NSString *)string

    if(string == nil || [string length] == 0) return nil;
    unsigned char digest[CC_MD5_DIGEST_LENGTH], i;

  • 微信支付结果回调
    请参考开始支付宝结果回调,两个方法中有写到微信,接下来就只写微信支付结果的处理,也是在appdelegate中实现
#pragma mark - 微信支付
//9.0前的方法,为了适配低版本 保留
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
    return [WXApi handleOpenURL:url delegate:self];
}


//微信SDK自带的方法,处理从微信客户端完成操作后返回程序之后的回调方法,显示支付结果的
-(void) onResp:(BaseResp*)resp
{
    //启动微信支付的response
    NSString *payResoult = [NSString stringWithFormat:@"errcode:%d", resp.errCode];
    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 0:
                payResoult = @"支付结果:成功!";
                break;
            case -1:
                payResoult = @"支付结果:失败!";
                break;
            case -2:
                payResoult = @"用户已经退出支付!";
                break;
            default:
                payResoult = [NSString stringWithFormat:@"支付结果:失败!retcode = %d, retstr = %@", resp.errCode,resp.errStr];
                break;
        }
    }
}

可以在获取支付结果成功或失败的时候发送通知,以便在支付的界面处理成功或失败的操作

//支付宝发送支付结果通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"AliPay" object:resultDic[@"resultStatus"]];
//在调用支付界面接受通知(viewDidLoad中实现)
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(alipay:) name:@"AliPay" object:nil];
//支付宝客户端支付成功通知
- (void)alipay:(NSNotification *)not{
    if ([not.object isEqualToString:@"9000"]) {
        //支付成功
    }else if ([not.object isEqualToString:@"6001"]){
        //用户取消支付
    }else{
        //支付失败
    }
    [[NSNotificationCenter defaultCenter] removeObserver:not];
}
//微信发送支付结果通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"WechatPay" object:[NSString stringWithFormat:@"%d", resp.errCode]];
//在调用支付界面接受通知(viewDidLoad中实现)
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(wechatPayResult:) name:@"WechatPay" object:nil];
#pragma mark - 微信回调
- (void)wechatPayResult:(NSNotification *)not{
    if ([not.object integerValue] == 0) {
        //支付成功
    }else if ([not.object integerValue] == -1){
        //支付失败
    }else if ([not.object integerValue] == -2){
        //用户退出支付
    }
    [[NSNotificationCenter defaultCenter] removeObserver:not];
}
