iOS开发支付宝支付成功返回字符串的处理操作

{
  memo="";
  result="partner=\"311811\"&seller_id=\"[e-mail]\"&out_trade_no=\"s005372\"&subject=\"\u522b\u5885\u8ba2\u5355\"&body=\"\u5885\"&total_fee=\"0.1\"&notify_url=\"http://baidu.com\"&service=\"mobile.secy.pay\"&payment_type=\"1\"&_input_charset=\"utf-8\"&it_b_pay=\"30m\"&success=\"true\"&sign_type=\"rsa\"&sign=\"dmiqkrzvnptnjp9zbwgnal3bu43rmocnwoasryfnuezx8uwy81zxhlg=\"";
  resultstatus=9000;
}

如上所示，为支付宝的返回数据结果。可能有的同学就懵了，这个result是一个字符串怎么把它分解成字典用那。

我封装了一个方法可以用

/**
 * 支付宝返回字段解析
 *
 * @param allstring      字段
 * @param firstseparatestring 第一个分离字段的词
 * @param secondseparatestring 第二个分离字段的词
 *
 * @return 返回字典
 */
+(nsdictionary *)vecomponentsstringtodic:(nsstring*)allstring withseparatestring:(nsstring *)firstseparatestring andseparatestring:(nsstring *)secondseparatestring;
+(nsmutabledictionary *)vecomponentsstringtodic:(nsstring*)allstring withseparatestring:(nsstring *)firstseparatestring andseparatestring:(nsstring*)secondseparatestring{
  nsmutabledictionary *dic=[nsmutabledictionary dictionary];
  nsarray *firstarr=[allstring componentsseparatedbystring:firstseparatestring];
  for (int i=0; i<firstarr.count; i++) {
    nsstring *firststr=firstarr[i];
    nsarray *secondarr=[firststr componentsseparatedbystring:secondseparatestring];
    [dic setobject:secondarr[1] forkey:secondarr[0]];
  }
  return dic;
}

在appdelegate用的时候代码如下

-(bool)application:(uiapplication *)application openurl:(nsurl *)url sourceapplication:(nsstring *)sourceapplication annotation:(id)annotation
{
    [[alipaysdk defaultservice] processorderwithpaymentresult:url standbycallback:^(nsdictionary *resultdic) {
      nsinteger orderstate=[resultdic[@"resultstatus"]integervalue];
      if (orderstate==9000) {
        nsstring *allstring=resultdic[@"result"];
        nsstring * firstseparatestring=@"\"&";
        nsstring * secondseparatestring=@"=\"";
        nsmutabledictionary *dic=[commontoolsvecomponentsstringtodic:allstring withseparatestring:firstseparatestring andseparatestring:secondseparatestring];
        nslog(@"ali=%@",dic);
        if ([dic[@"success"]isequaltostring:@"true"]) {
           [[nsnotificationcenter defaultcenter] postnotificationname:@"alipaysucceed" object:nil userinfo:dic];
        }
      }else{
        nsstring *returnstr;
        switch (orderstate) {
          case 8000:
            returnstr=@"订单正在处理中";
            break;
          case 4000:
            returnstr=@"订单支付失败";
            break;
          case 6001:
            returnstr=@"订单取消";
            break;
          case 6002:
            returnstr=@"网络连接出错";
            break;
          default:
            break;
        }
        [hudtooles showtexthud:returnstr];
        [hudtooles removehud:4];
      }
    }];
}
