Channel Button

1. Moving Channel Button

You have the option to adjust the position of the Channel button via the ChannelButtonOption.
After making changes to this option, apply it to the property value of BootConfig. For example:

let config = BootConfig()
config.channelButtonOption = ChannelButtonOption(
  position: .left, 
  xMargin: 100, 
  yMargin: 200
)

ChannelIO.boot(with: config) { 

	...

}

BootConfig *config = [BootConfig alloc] init];
ChannelButtonOption* option = [ChannelButtonOption alloc] initWithPosition: ChannelButtonPositionLeft xMargin:20 yMargin: 20];
[config setChannelButtonOption: option];

2. Custom Channel Button

If you wish to customize the appearance of the Channel button, apart from the few pre-set options, you will need to create your own button.

Make sure to hide the default Channel button by calling ChannelIO.hideChannelButton.
Once you've created your button and positioned it as desired, link the ChannelIO.showMessenger to the button's touch event.

3. Display the number of unread messages

We recommend using onBadgeChanged to display the number of unread messages. If you choose to customize the Channel button, the count of unread messages will not be visible.

To implement the onBadgeChanged, ensure that theChannelPluginDelegate is adopted. For instance:

class MyAwesomeApp: UIViewController {
  func viewDidLoad() {
    super.viewDidLoad()
    ChannelIO.delegate = self
  }
}

extension MyAwesomeApp : ChannelPluginDelegate {
  func onBadgeChanged(unread: Int, alert: Int) {
    //do something with count
  }
}

//in MyAwesomeApp.h
@interface MyAwesomeApp : UIViewController<ChannelPluginDelegate> 
//your properties..
@end

//in MyAwesomeApp.m
@implementation MyAwesomeApp
- (void)viewDidLoad {
    [super viewDidLoad];
    ChannelIO.delegate = self;
}

- (void)onBadgeChangedWithCount:(NSInteger)count {
    //do something with count
}

Customizing in-app popup

By default, the SDK delivers the following in-app pop-up notifications to your app, which is applicable when the user uses the app online.

1. In-App Pop-up Information

To receive in-app push notifications, you need to adopt theChannelPluginDelegate and implement the onPopupDataReceived method. Here's an example:

class MyAwesomeApp: UIViewController {
  func viewDidLoad() {
    super.viewDidLoad()
    ChannelIO.delegate = self
  }
}

extension MyAwesomeApp: ChannelPluginDelegate {
  func onPopupDataReceived(event: PopupData) {
		//configure your view with push event data 
    //and display 
	}
}

//in MyAwesomeApp.h
@interface MyAwesomeApp : UIViewController<ChannelPluginDelegate> 
//your properties..
@end

//in MyAwesomeApp.m
@implementation MyAwesomeApp
- (void)viewDidLoad {
    [super viewDidLoad];
    ChannelIO.delegate = self;
}

- (void)onPopupDataReceivedWithEvent:(PopupData *)event {
    //configure your view with push event data 
    //and display 
}

2. Customizing the Appearance of In-App Popup Notifications

To customize the appearance of the In-App Push notifications, you must create and utilize your own in-app push notification screen.

Make sure the default in-app push view remains hidden by setting the hidePopup option of BootConfig to true.
Perform a new Boot using the above BootConfig.
Utilize the onPoupupDataReceived method implemented in step 1 to fill in your customized in-app push notification view.

Event tracking

1. Custom Event Tracking

Utilize the track method to track a specific action of the user.

Below is an description of how to log an event when a user utilizing the SDK approaches a specific ViewController, MyAwesomeAppViewController.

class MyAwesomeAppViewController: UIViewController {
  override func viewDidLoad() {
    super.viewDidLoad()
    ChannelIO.track(
      eventName:"awesome_visited",
      eventProperty: [
        "visitedAt": "1521232131",
        "hasClickedButtonA": true,
        "otherMeta": "etc",
      ])
  }
}

//in MyAwesomeApp.h
@interface MyAwesomeApp : UIViewController
//your properties..
@end

//in MyAwesomeApp.m
@implementation MyAwesomeApp
- (void)viewDidLoad {
    [super viewDidLoad];
    [ChannelIO trackWithEventName:@"awesome_visited" eventProperty:{
      @"visitedAt": @"",
      @"hasClickedButtonA": @(YES),
      @"otherMeta": @"etc"
    }];
}
