QuickBlox "Unexpected Signature" error while making session with REST Api in iOS

This might be a repeated question but I can't find anything about what is wrong about it, I have been trying to generate a session via QuickBlox's rest API, it has consumed 5 days but I can't get it through. Please help me out

Setting the body

NSString *strNonceValue = [NSString stringWithFormat:@"%d", arc4random() % 1000000];
    NSString *timeStampValue = [NSString stringWithFormat:@"%ld", (long)[[NSDate date] timeIntervalSince1970]];

NSMutableDictionary *dictSessionInfo = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
                                            applicationID, @"application_id",
                                            _pAuthorizationKey, @"auth_key",
                                            timeStampValue, @"timestamp",
                                            strNonceValue, @"nonce", nil];

NSString *signature = [self generateSignatureWithText:dataVal andKey:_pAuthorizationKey];

[dictSessionInfo setObject:signature forKey:@"signature"];

NSData *data = [NSJSONSerialization dataWithJSONObject:dictSessionInfo options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

Getting Signature

- (NSString *)generateSignatureWithText:(NSData *)data andKey:(NSString *)secret {

    NSData *secretData = [secret dataUsingEncoding:NSUTF8StringEncoding];
    NSData *clearTextData = data;
    uint8_t digest[CC_SHA1_DIGEST_LENGTH] = {0};
    CCHmacContext hmacContext;
    CCHmacInit(&hmacContext, kCCHmacAlgSHA1, secretData.bytes, secretData.length);
    CCHmacUpdate(&hmacContext, clearTextData.bytes, clearTextData.length);
    CCHmacFinal(&hmacContext, digest);
    NSData *result = [NSData dataWithBytes:digest length:CC_SHA1_DIGEST_LENGTH];
    NSString *hash = [result description];
    hash = [hash stringByReplacingOccurrencesOfString:@" " withString:@""];
    hash = [hash stringByReplacingOccurrencesOfString:@"<" withString:@""];
    hash = [hash stringByReplacingOccurrencesOfString:@">" withString:@""];

    return hash;   
}

Generating URLRequest 

requestURL = [requestURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url=[NSURL URLWithString:requestURL];
NSString *postLength=@"";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setTimeoutInterval:60];
[request setURL:url];
NSLog(@"HTTP body Fields : %@", combinedDataStr);
if([requestType isEqualToString:@"POST"]) {
    NSData *postData = [combinedDataStr dataUsingEncoding:NSASCIIStringEncoding
                                     allowLossyConversion:YES];
    postLength = [NSString stringWithFormat:@"%ld", (unsigned long)[postData length]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:postData];
}
else
    [request setHTTPMethod:@"GET"];

[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"0.1.0"            forHTTPHeaderField:@"QuickBlox-REST-API-Version"];

The response I am receiving is :

response dict : {
    errors =     {
        base =         (
            "Unexpected signature"
        );
    };
}

Please look into this and let me know what I am doing wrong

As far as I understand, the problem is with this line

NSString *signature = [self generateSignatureWithText:dataVal andKey:_pAuthorizationKey];

you use auth key to create a signature, but you should pass here secret key

so, try to replace _pAuthorizationKey with secret key
