Estou usando o serviço SOAP Envelope para usá-lo,

Aqui está o meu código

@property(retain,nonatomic)NSString *xmlString;

@property(nonatomic,retain)NSMutableData *webResponseData;


-(void)method_GetUpcomingLotteries
{

    NSString *soapMessage = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
                             "<env:Envelope xmlns:env=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:ns1=\"urn:Lottery.Intf-ILottery\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:enc=\"http://www.w3.org/2003/05/soap-encoding\">\n"
                             "<env:Body>\n"
                             "<ns1:GetUpcomingLotteries env:encodingStyle=\"http://www.w3.org/2003/05/soap-encoding\">\n"
                             "<EntityID xsi:type=\"xsd:int\">2</EntityID>\n"
                             "<Password xsi:type=\"xsd:string\">Smart@Winners</Password>\n"
                             "<SortBy xsi:type=\"xsd:int\">0</SortBy>\n"
                             "<limit xsi:type=\"xsd:int\">0</limit>\n"
                             "</ns1:GetUpcomingLotteries>\n"
                             "</env:Body>\n"
                             "</env:Envelope>"];


    NSURL *sRequestURL = [NSURL URLWithString:@"http://isapi.mekashron.com/soapclient/soapclient.php?"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:sRequestURL];
    NSString *sMessageLength = [NSString stringWithFormat:@"%d", [soapMessage length]];

    [request addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue: @"urn:Lottery.Intf-ILottery/GetUpcomingLotteries" forHTTPHeaderField:@"SOAPAction"];
    [request addValue: sMessageLength forHTTPHeaderField:@"Content-Length"];

    [request setHTTPMethod:@"POST"];



    [request setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

    NSLog(@"soapMessage===\n %@",soapMessage);

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

    if( theConnection ) {
        NSLog(@"hiii");
        self.webResponseData = [NSMutableData data];
    }else {
        NSLog(@"Some error occurred in Connection");

    }
}



- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"Received Bytes from server: %lu", (unsigned long)[self.webResponseData length]);

    NSString * strXml = [[NSString alloc] initWithBytes: [self.webResponseData mutableBytes] length:[self.webResponseData length] encoding:NSUTF8StringEncoding];

    NSLog(@"---- %@" ,strXml);



}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {

    [self.webResponseData  setLength:0];
}

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [self.webResponseData  appendData:data];
}

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    NSLog(@"Some error in your Connection. Please try again.");


}

Minha pergunta :

1) Diga-me que preciso alterar meu método ou alterar o servidor final para transferir minha API do IPv4 para o IPv6?

2) Código para IpV6 usando o método SOAP sob ios9 que funciona substituindo NSURLConnection
