but none did help me to integrate alipay .Can anyone plz tell how to figure out this Integration in my iOS project.

Answer 1

there are two ways to do this

1. Integrate the Alipay SDK and use Alipay app to do the job. SDK download from: https://openhome.alipay.com/doc/docIndex.htm#goto=https://openhome.alipay.com/doc/viewKbDoc.htm?key=236698_261849&type=info

2. Develop a WAP web to pay on web, this is not our job…

also for demo you can look here Alipay SDK

Use Alipay to a complete payment function, we have the following steps: 1) The first contract and pay treasure, obtain business ID (partner) and account ID(seller) (this is mainly in charge of the company) 2) Download a public and private key file (with the corresponding encryption and signature) 3) Download SDK (login pay treasure: /) It provides how to a very detailed document, contract, how to obtain a public and private key, how to call the payment interface. 4) To generate orders information 5) Call to pay treasure to the client, the client by Alipay Alipay secure server dealing 6) Payment after payment to the merchant returned to the client and server.There is a Demo. integrated Alipay function of SDK; the specific mode of operation of integrated payment function, you can refer to the Demo 7) include alipay sdk from above demo link.

80         }
81 
82     }
83 
84     [tableView deselectRowAtIndexPath:indexPath animated:YES];
85 }

The main integration is the key to the following steps:

//.Package model order
AlixPayOrder *order = [[AlixPayOrder alloc] init];
// To generate orders description
NSString *orderSpec = [order description];

//The sign of the 2
id<DataSigner> signer = CreateRSADataSigner(@"The private key key");
// Incoming order description of signature
NSString *signedString = [signer signString:orderSpec];


//3 generation order string
NSString *orderString = [NSString stringWithFormat:@"%@&sign=\"%@\"&sign_type=\"%@\"",
                         orderSpec, signedString, @"RSA"];

//The 4 call to the payment interface
AlixPay * alixpay = [AlixPay shared];
// appScheme: The first merchant own protocol
int ret = [alixpay pay:orderString applicationScheme:appScheme];
