CCAvenueアクション後に元に戻す

Question

以下はCCAvnenueを統合したコードですが、失敗したトランザクション、キャンセルされたトランザクション、成功したトランザクションなどのアクションの後に、

//Getting RSA Key 
NSString *rsaKeyDataStr = [NSString stringWithFormat:@"access_code=%@&order_id=%@",access_code,order_id]; 
NSData *requestData = [NSData dataWithBytes: [rsaKeyDataStr UTF8String] length: [rsaKeyDataStr length]]; 
NSMutableURLRequest *rsaRequest = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString:rsa_key_url]]; 
[rsaRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"]; 
[rsaRequest setHTTPMethod: @"POST"]; 
[rsaRequest setHTTPBody: requestData]; 
NSData *rsaKeyData = [NSURLConnection sendSynchronousRequest: rsaRequest returningResponse: nil error: nil]; 
NSString *rsaKey = [[NSString alloc] initWithData:rsaKeyData encoding:NSASCIIStringEncoding]; 
rsaKey = [rsaKey stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]]; 
rsaKey = [NSString stringWithFormat:@"-----BEGIN PUBLIC KEY-----\n%@\n-----END PUBLIC KEY-----\n",rsaKey]; 

//Encrypting Card Details 

NSString *myRequestString = [NSString stringWithFormat:@"amount=%@&currency=%@",PayText.text,currency]; 
CCTool *ccTool = [[CCTool alloc] init]; 
NSString *encVal = [ccTool encryptRSA:myRequestString key:rsaKey]; 
encVal = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL, 
                       (CFStringRef)encVal, 
                       NULL, 
                       (CFStringRef)@"!*'();:@&=+$,/?%#[]", 
                       kCFStringEncodingUTF8)); 
[ProgressHUD show:@"Please wait..."]; 
//Preparing for a webview call 

NSString *urlAsString = [NSString stringWithFormat:@"https://secure.ccavenue.com/transaction/initTrans"]; 
NSString *encryptedStr = [NSString stringWithFormat:@"merchant_id=%@&order_id=%@&redirect_url=%@&cancel_url=%@&enc_val=%@&access_code=%@&billing_name=%@&billing_address=%@&billing_country=India&billing_tel=%@&billing_email=%@&billing_zip=110092&billing_state=Delhi&billing_city=New Delhi",merchant_id,order_id,redirect_url,cancel_url,encVal,access_code,billing_name,billing_address,billing_tel,billing_email]; 

NSData *myRequestData = [NSData dataWithBytes: [encryptedStr UTF8String] length: [encryptedStr length]]; 
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: urlAsString]]; 
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"]; 
[request setValue:urlAsString forHTTPHeaderField:@"Referer"]; 
[request setHTTPMethod: @"POST"]; 
[request setHTTPBody: myRequestData]; 
[_Web loadRequest:request]; 

}

NSString *string = webView.request.URL.absoluteString; 

if ([string rangeOfString:@"/ccavResponseHandler.php"].location != NSNotFound) { 
    NSString *html = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.outerHTML"]; 

    NSString *transStatus = @"Not Known"; 

    if (([html rangeOfString:@"Aborted"].location != NSNotFound) || 
     ([html rangeOfString:@"Cancel"].location != NSNotFound)) { 


     transStatus = @"Transaction Cancelled"; 

    } 
    else if (([html rangeOfString:@"Success"].location != NSNotFound)) { 

     transStatus = @"Transaction Successful"; 


    } 
    else if (([html rangeOfString:@"Fail"].location != NSNotFound)) { 


     transStatus = @"Transaction Failed"; 

    } 
}
