How to: add SDK to Xcode and connect to the cloud

Read Connecting Quickblox Framework with Your Project

Getting started

iOS SDK is really simple to use. In just a few minutes you can power up your mobile app with huge amount of awesome communication features & data services.

The common way to interact with QuickBlox can be presented with the following sequence of actions:

  1. Initialize framework with application credentials
  2. Login with existing user or register new one
  3. Perform actions with QuickBlox communication services and any data entities (users, locations, files, custom objects, pushes etc.)

Initialize framework

[QBSettings setApplicationID:92];
[QBSettings setAuthKey:@"wJHdOcQSxXQGWx5"];
[QBSettings setAuthSecret:@"BTFsj7Rtt27DAmT"];
[QBSettings setAccountKey:@"7yvNe17TnjNUqDoPwfqp"];

It's also possible to initialise the SDK with an existent QuickBlox token. It can be interesting in cases when you build a big system and you have the server side which generates QuickBlox tokens for example:

[QBSettings setApplicationID:92];
[QBSettings setAuthKey:@""]; // don't need to set
[QBSettings setAuthSecret:@""]; // don't need to set
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss z"];
NSDate *expirationDate = [formatter dateFromString:@"2014-10-20 11:13:06 UTC"];
QBASession *session = [QBASession new];
session.token = @"f23d03bd2341a1f923b7d4c1fbee97af1cd296f2";
// updateSessionBlock executes synchronously on background thread and you are allowed to execute synchronous URL request
// and to block a background thread from executing until you receive updated credentials
// by the end of updateSessionBlock you should call startSessionWithDetails: with updated credentials
[[QBSession currentSession] startSessionWithDetails:session updateSessionBlock:{
// Execute synchronous URL request to retrieve new token from custom server
// Until the end of this block all the operations will be paused
QBASession *updatedSession = [QBASession new];
session.token = @"new token";
[[QBSession currentSession] startSessionWithDetails:updatedSession];

A few words about Authentication and Authorization


Stating from QuickBlox iOS SDK 2.4 you don't need to manage session manually. SDK will automatically do all this job.

After login a REST session will be available for 2 hours.

When the session expires, any QBRequest method will firstly renew it and then execute itself.

To be able to use QuickBlox API you have to create a user and be signed in.

To create a user use the following snippet:

QBUUser *user = [QBUUser user];
user.login = @"garry";
user.password = @"garry5santos";
[QBRequest signUp:user successBlock:^(QBResponse *response, QBUUser *user) {
    // Success, do something
} errorBlock:^(QBResponse *response) {
    // error handling
    NSLog(@"error: %@", response.error);

Then you can login with the user:

[QBRequest logInWithUserLogin:@"garry" password:@"garry5santos" successBlock:^(QBResponse *response, QBUUser *user) {
    // Success, do something
} errorBlock:^(QBResponse *response) {
    // error handling
    NSLog(@"error: %@", response.error);

In order to use real time features you have to be logged in to Chat:

QBUUser *currentUser = [QBUUser user];
currentUser.ID = 2569; // your current user's ID
currentUser.password = @"garrySant88"; // your current user's password   
[[QBChat instance] connectWithUser:user completion:^(NSError * _Nullable error) {
    NSLog(@"Error: %@", error);

Endpoints customization

You may need to configure custom endpoints to point your application to a custom backend.

This should be called in AppDelegate.m in the method


//Set settings for zone
[QBSettings setApiEndpoint:@"" chatEndpoint:@"" forServiceZone:QBConnectionZoneTypeProduction];
// Activate zone
[QBSettings setServiceZone:QBConnectionZoneTypeProduction];

iOS SDK Transition guide from version 1.9 to 2.0

Transition guide from version 1.9 to 2.x

Main changes

  • ARC compatible
  • Block callbacks
  • JSON based requests to QuickBlox API
  • General restructuring and reachitecture
  • Cocoapods integration

All requests to QuickBlox now start from QBRequest class.

CocoaPods integration

Remember: Be sure that you have $(inherited) in Other Linker Flags in build settings. Otherwise you will receive linking errors with undefined classes.

To install QuickBlox framework using CocoaPods - you should just add following line in your Podfile:

pod 'QuickBlox'

And run pod install in your Terminal.

That's all :)

More info you can find on, Get Started section.

Connecting to QuickBlox 1.9 SDK

[QBSettings setApplicationID:92];
[QBSettings setAuthorizationKey:@"wJHdOcQSxXQGWx5"];
[QBSettings setAuthorizationSecret:@"BTFsj7Rtt27DAmT"];
[QBSettings setAccountKey:@"7yvNe17TnjNUqDoPwfqp"];

2.0 SDK

[QBApplication sharedApplication].applicationId = 92;
[QBConnection registerServiceKey:@"wJHdOcQSxXQGWx5"];
[QBConnection registerServiceSecret:@"BTFsj7Rtt27DAmT"];
[QBSettings setAccountKey:@"7yvNe17TnjNUqDoPwfqp"];

QBSettings is replaced with:

  • QBApplication class is used for storing your app applicationId.
  • QBConnection class stores service key and secret.

Creating session example 1.9 SDK

[QBAuth createSessionWithExtendedRequest:extendedAuthRequest delegate:self];
#pragma mark -
#pragma mark QBActionStatusDelegate
// QuickBlox API queries delegate
- (void)completedWithResult:(QBResult*)result{
    // QuickBlox session creation result
    if( [result isKindOfClass:[QBAAuthSessionCreationResult class]] ){
        if( result.success ){
            // session created

2.0 SDK

[QBRequest createSessionWithSuccessBlock:^(QBResponse *response, QBASession *session) {
    // session created
} errorBlock:^(QBResponse *response) {
    // handle errors
    NSLog("%@", response.error);

Instead of QBActionStatusDelegate you need to implement block callbacks. In success block you could use QBASession object. If error block is fired you could look at error property of response object.

Upload/Download progress block example 1.9 SDK

UIImage *image = [UIImage imageNamed:@"greatImage.png"];
NSData* imageData = UIImagePNGRepresentation(image);
[QBContent TUploadFile:imageData fileName:@"Great Image" contentType:@"image/png" isPublic:NO delegate:self];
#pragma mark -
#pragma mark QBActionStatusDelegate
- (void)setProgress:(float)progress{
    NSLog(@"progress: %f", progress);

2.0 SDK

// show progress changes
QBRequestStatusUpdateBlock block = ^(QBRequest *request, QBRequestStatus *status) {
    NSLog(@"%f", status.percentOfCompletion);
// Upload file to QuickBlox server
UIImage *image = [UIImage imageNamed:@"greatImage.png"];
NSData* imageData = UIImagePNGRepresentation(image);
QBRequest *request = [QBRequest TUploadFile:imageData fileName:@"Great Image" contentType:@"image/png" isPublic:NO successBlock:nil statusBlock:block errorBlock:nil];

Push notification changes 1.9 SDK

// AppDelegate.m
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
    NSLog(@"didReceiveRemoteNotification userInfo=%@", userInfo);
// YourClass.m
QBASessionCreationRequest *extendedAuthRequest = [QBASessionCreationRequest request];
extendedAuthRequest.userLogin = @"injoitUser1";
extendedAuthRequest.userPassword = @"injoitUser1";
// QuickBlox session creation
[QBAuth createSessionWithExtendedRequest:extendedAuthRequest delegate:self];
#pragma mark -
#pragma mark QBActionStatusDelegate
// QuickBlox API queries delegate
- (void)completedWithResult:(QBResult *)result{
    // Success result
    if( result.success ){
        // QuickBlox session creation result
        if( [result isKindOfClass:[QBAAuthSessionCreationResult class]] ){            
            // Register as subscriber for Push Notifications
            [QBMessages TRegisterSubscriptionWithDelegate:self];
        // QuickBlox register for Push Notifications result
        else if( [result isKindOfClass:[QBMRegisterSubscriptionTaskResult class]] ){
            // you can now receive push notifications
        // show Errors

2.0 SDK

// AppDelegate.m
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
    NSLog(@"didReceiveRemoteNotification userInfo=%@", userInfo);
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    // register for push notifications
    [QBRequest registerSubscriptionForDeviceToken:deviceToken successBlock:^(QBResponse *response, NSArray *subscriptions) {
    // successfully subscribed
    } errorBlock:nil];
// YourClass.m
// Create extended session request (for push notifications)
QBSessionParameters *parameters = [[QBSessionParameters alloc] init];
parameters.userLogin = @"injoitUser1";
parameters.userPassword = @"injoitUser1";
// QuickBlox session creation
[QBRequest createSessionWithExtendedParameters:parameters successBlock:^(QBResponse *response, QBASession *session) {
    UIRemoteNotificationType types = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound;
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:types];
} errorBlock:nil];

Errors 2.0 SDK

If errorBlock of the request is fired you have a response object within block:

[QBRequest userWithExternalID:555 successBlock:^(QBResponse *response, QBUUser *user) {
    NSLog(@"Successfull response!");
} errorBlock:^(QBResponse *response) {
    NSLog(@"Response error: %@", response.error.reasons);

From QBResponse class you could get information about failed request. error property is an instance of QBError class that stores information about error. reasons property of QBError class contains NSDictionary with human readable reasons of failure. If the reasons is nil than you could look at error property of QBError to identify where is the problem.
