How to remove error 'unrecognized selector' while trying to login user to QBChat

Question

I'm new to Quickblox for iOS and trying to login user to QBChat but I'm receiving unrecognized selector.

Here is the code:

if ([result isKindOfClass:[QBAAuthSessionCreationResult class]]) {
  QBUUser *currentUser=[QBUUser user];
  currentUser.login=@"test0123";
   currentUser.password=@"test0123";

if (result.success) {
    // Session is created...
    //Login to QuickBlox Chat
    [[QBChat instance] setDelegate: self];
    [[QBChat instance] loginWithUser: currentUser];
  }
}

I am receiving following log:

-[QBChat loginWithUser:] -> Connecting to Chat, hostName: chat.quickblox.com
-[QBChat loginWithUser:] -> Chat server endpoint: chat.quickblox.com, User JID:xxxxxxxx
-[QBDDXMLElement attributeFloatValueForName:withDefaultValue:]: unrecognized selector sent to instance 0x17442b0e0.

Try this:

if ([result isKindOfClass:[QBAAuthSessionCreationResult class]]) {

    if (result.success) {
        QBAAuthSessionCreationResult *res = (QBAAuthSessionCreationResult *)result;
        QBUUser *currentUser = [QBUUser user];

        currentUser.ID = res.session.userID;
        currentUser.login = self.sessionLogin;
        currentUser.password = self.sessionPassword;

        if ([[QBChat instance] isLoggedIn] == NO) {
            [[QBChat instance] setDelegate:self];
            [[QBChat instance] loginWithUser:currentUser];
        }

    } else {
        // Handle error
    }
}

Thank you for improving my question. But I'm still receiving the same logged error. I have followed a previous answer: [link](http://stackoverflow.com/questions/14140132/creating-chat-room-in-quickblox) in hopes to solve this issue but the issue persists. – PhilT Mar 19 '15 at 05:44
Generally, you should follow the steps on quickblox website instead, which is more up to date: http://quickblox.com/developers/SimpleSample-chat_users-ios – Mustafa Mar 19 '15 at 06:57
Experiencing similar unrecognized selector error with this method: `[QBRequest createSessionWithExtendedParameters:parameters successBlock:^(QBResponse *response, QBASession *session) {}` – PhilT Mar 20 '15 at 01:34
You should run, test, and debug the SimpleSample-chat application provided by Quickblox. It might give you some insight into what you're missing. That's the only help/advice I can give you, considering the available information. – Mustafa Mar 20 '15 at 10:55

If you have an old SDK, please try new SDK with CocoaPods http://quickblox.com/developers/IOS-how-to-connect-Quickblox-framework#CocoaPods

And also please try sample projects https://github.com/QuickBlox/quickblox-ios-sdk

they have the same logic that you have and everything works without crashes

Thank you for the advice! I've gone the cocoapods and ios sample project route and stumbled on the main issue: in QBDDXMLNode.h which states: "Lexical or Preprocessor Issue 'libxml/tree.h' file not found." Any ideas? And yes...I have added the frameworks and the necessary flags to the Other Linker Flags. – PhilT Mar 23 '15 at 13:57
use Google :) http://stackoverflow.com/questions/26857531/import-libxml-tree-h-file-not-found-after-xcode-6-1-update http://stackoverflow.com/questions/14622684/import-libxml-tree-h-file-not-found-after-xcode-update – SevenDays Mar 23 '15 at 16:18
@PhilT also please ensure you set -ObjC in linker flags. – SevenDays Apr 15 '15 at 10:19
