Customization (CoreSDK)

Our SDK's come with a pre-built UI that you can use to integrate with your application. Following is a list of things that you can customize in the pre-built UI.


In case you are looking for deeper customization, please feel free to use our UI source code mentioned below for reference to build your own UI.


This will only work if you are using Applozic framework/pod not ApplozicSwift framework/pod

We provide various UI settings to customise chat view easily. You can add these settings in ALDefaultChatViewSettings method in the ALChatManager file.

On User Profile Tap

Use the below code to get the profile tap notification event to your app

/// add the observer to listen the tap event 
[[NSNotificationCenter defaultCenter]

/// Once user taps you will get the details here 
-(void)onProfileTap:(NSNotification *)notification {
    NSDictionary *tapUserInfoDictionary = notification.userInfo;
    NSString * userId = [tapUserInfoDictionary valueForKey:ThirdPartyDetailVCNotificationALContact];
    ALContactService * contactService = [[ALContactService alloc] init];
    ALContact * contact = [contactService loadContactByKey:@"userId" value:userId];
    NSLog(@"onProfileTap userId %@", contact.userId);
/// Add the observer 
NotificationCenter.default.addObserver(self, selector: #selector(onProfileTap(notification:)), name: NSNotification.Name(rawValue: ThirdPartyDetailVCNotificationALContact), object: nil)    
/// Once user taps you will get the details here 
@objc func onProfileTap(notification: NSNotification) {
        guard let tapUserInfoDictionary = notification.userInfo else {
        let userId = tapUserInfoDictionary[ThirdPartyDetailVCNotificationALContact] as? String
        let contactService = ALContactService()
        let contact = contactService.loadContact(byKey: "userId", value: userId)

        print("UserId  %@", contact?.userId)
        print("Display name %@", contact?.getDisplayName())


NOTE: Disable the existing profile tap using the below code

[ALApplozicSettings openChatOnTapUserProfile:NO];
ALApplozicSettings.openChat(onTapUserProfile: false)

Container View

You can also add our ChatList view as a subview. To do that enter the below code in your ViewController's viewDidLoad method:

UIView * containerView = [[UIView alloc] init];
containerView.translatesAutoresizingMaskIntoConstraints = false;
[self.view addSubview:containerView];

[containerView.leadingAnchor constraintEqualToAnchor: self.view.leadingAnchor].active = true;
[containerView.trailingAnchor constraintEqualToAnchor: self.view.trailingAnchor].active = true;
[containerView.topAnchor constraintEqualToAnchor:self.view.topAnchor].active = true;
[containerView.bottomAnchor constraintEqualToAnchor:self.view.bottomAnchor].active = true;

// Add child view controller view to container
NSBundle * bundle = [NSBundle bundleForClass:ALMessagesViewController.class];
UIStoryboard * storyboard = [UIStoryboard storyboardWithName: @"Applozic" bundle:bundle];
UIViewController * controller = [storyboard instantiateViewControllerWithIdentifier:@"ALViewController"];
[self addChildViewController: controller];
controller.view.translatesAutoresizingMaskIntoConstraints = false;
[containerView addSubview:controller.view];

[controller.view.leadingAnchor constraintEqualToAnchor: containerView.leadingAnchor].active = true;
[controller.view.trailingAnchor constraintEqualToAnchor: containerView.trailingAnchor].active = true;
[controller.view.topAnchor constraintEqualToAnchor:containerView.topAnchor].active = true;
[controller.view.bottomAnchor constraintEqualToAnchor:containerView.bottomAnchor].active = true;

[controller didMoveToParentViewController:self];
let containerView = UIView()
containerView.translatesAutoresizingMaskIntoConstraints = false
    containerView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 0),
    containerView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: 0),
    containerView.topAnchor.constraint(equalTo: view.topAnchor, constant: 0),
    containerView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 0),

// Add child view controller view to container
let story = UIStoryboard(name: "Applozic", bundle: Bundle(for: ALMessagesViewController.self))
let controller = story.instantiateViewController(withIdentifier: "ALViewController")
controller.view.translatesAutoresizingMaskIntoConstraints = false

    controller.view.leadingAnchor.constraint(equalTo: containerView.leadingAnchor),
    controller.view.trailingAnchor.constraint(equalTo: containerView.trailingAnchor),
    controller.view.topAnchor.constraint(equalTo: containerView.topAnchor),
    controller.view.bottomAnchor.constraint(equalTo: containerView.bottomAnchor)

controller.didMove(toParentViewController: self)

In ALChatManager.m file in method ALDefaultChatViewSettings set the viewController name using the below settings: Pass your view controller name where the ChatList is added to

[ALApplozicSettings setMsgContainerVC:[YOUR-VIEW-CONTROLLER-NAME description]];
ALApplozicSettings.setMsgContainerVC(YOUR-VIEW-CONTROLLER-NAME .description())

To start the contacts view Controller on click on the navigation bar button you can use this code to start it

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Applozic" bundle:[NSBundle bundleForClass:ALChatViewController.class]];
ALNewContactsViewController *contactVC = (ALNewContactsViewController *)[storyboard instantiateViewControllerWithIdentifier:@"ALNewContactsViewController"]; contactVC.forGroup = [NSNumber numberWithInt:0];
[self.navigationController pushViewController:contactVC animated:YES];
let storyboard = UIStoryboard(name: "Applozic", bundle: Bundle(for: ALChatViewController.self))
let contactVC = storyboard.instantiateViewController(withIdentifier: "ALNewContactsViewController") as? ALNewContactsViewController
        contactVC?.forGroup = NSNumber(value: 0)
   if let contactVC = contactVC {
       navigationController?.pushViewController(contactVC, animated: true)

UI Source Code

For complete control over UI, you can download our open source chat UI toolkit and change it as per your designs :

Import Applozic iOS Library into your Xcode project.

It contains the UI related source code, icons, views and other resources which you can customize based on your design needs.

Customise Pod

If you have added our SDK using CocoaPods then you should not directly modify our pod. If you modify our pod and later you want to update the pod then all the local changes will be removed.

The right way to do is to fork our repo then clone the repo and do the changes. Once you are done with the changes then push it. Now what you need to do is to use this forked repo in the pod. You need to pass the URL of this forked repo.

In your podfile you need to write it in this way:

pod 'Applozic', :git => '<url_of_your_forked_repo>'

then run pod install in the terminal

Later, when you want to update our SDK then just fetch the changes from our repo, and merge the changes to your forked repo. It will be updated.

If you just want to keep your changes locally, then clone the repo and do the changes. In your podfile, pass the path of your local repo.
