Objective-C

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [[TalkPlus sharedInstance] addChannelDelegate:self tag:@"tagHere"];

Swift

// Register delegate to handle channel event
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    TalkPlus.sharedInstance()?.add(self, tag: "tagHere")

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    TalkPlus.sharedInstance()?.removeChannelDelegate("tagHere")
}
