在iOS SDK中创建密码摘要

我正在我的iPhone应用程序中集成DigestPassword Web服务.为此,我需要生成nonce和passwordDigest.我努力了,但在Google搜索中找不到任何有用的例子.

我按照以下方式完成了：更新的代码：

NSString *user = @"XXXXXXXXXXXXXXXXXXXXXX";
NSNumber *nonce = @(arc4random());
NSLog(@"nonce %@",[self encodeStringTo64:[nonce stringValue]]);
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
NSString *created = [dateFormatter stringFromDate:[NSDate date]];
NSLog(@"created %@",created);
NSString *digest_concat = [NSString stringWithFormat:@"%@%@%@",nonce,created,@"Pwd@123"];

NSData *digestBytes = [self shaa1:digest_concat];
NSString *digestBase64 = [self base64forData:digestBytes];
NSLog(@"digestBase64 %@",digestBase64);

NSString *strSOAP = [NSString stringWithFormat:@"<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:v1=\"http://sita.aero/iborders/external/ReferralManagementServiceWSDLType/V1\"><soap:Header><wsse:Security xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\" xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\"><wsse:UsernameToken wsu:Id=\"UsernameToken-27E173B8CF239BE6F01440582357416191\"><wsse:Username>%@</wsse:Username><wsse:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest\">%@</wsse:Password><wsse:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">%@</wsse:Nonce><wsu:Created>%@</wsu:Created></wsse:UsernameToken></wsse:Security></soap:Header><soap:Body><v1:SearchReferralsRequest><v1:ReferralSearchCriteria><ReferralId>2038100</ReferralId></v1:ReferralSearchCriteria><v1:Paging><FetchNumber>1</FetchNumber><ResultsPerFetch>1</ResultsPerFetch></v1:Paging></v1:SearchReferralsRequest></soap:Body></soap:Envelope>",user,digestBase64,[self encodeStringTo64:[nonce stringValue]],created];

- (NSString*)encodeStringTo64:(NSString*)fromString{
    NSData *plainData = [fromString dataUsingEncoding:NSUTF8StringEncoding];
    NSString *base64String;
    if ([plainData respondsToSelector:@selector(base64EncodedStringWithOptions:)]) {
        base64String = [plainData base64EncodedStringWithOptions:kNilOptions];  // iOS 7+
    } else {
        base64String = [plainData base64Encoding];                              // pre iOS7
    }
    return base64String;
}

- (NSData *)shaa1:(NSString *)input {
NSData *data = [input dataUsingEncoding:NSUTF8StringEncoding];
uint8_t digest[CC_SHA1_DIGEST_LENGTH];
CC_SHA1(data.bytes,(CC_LONG) data.length,digest);
return [NSData dataWithBytes:digest length:CC_SHA1_DIGEST_LENGTH];

}

有人可以检查我的代码创建nonce和密码摘要,让我知道我正在做什么错误,因为我无法使用此访问Web服务？我总是收到Message Expired错误.
错误：

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
   <soap:Body>
      <soap:Fault>
         <soap:Code>
            <soap:Value>soap:Sender</soap:Value>

         </soap:Reason>

编辑：我想要的SOAP请求：
