Event Delegate

The iOS SDK provides event delegates to listen to various events on the client app. Through these event delegates, TapTalk.io notifies the client app of events that happen on your app. You will need to register the delegate objects to receive event callbacks from TapTalk.io.
Event Delegate Name
Description
Listens to general event changes in the application
Listens to UI-related events in Room List View when UI implementation type is used
Listens to UI-related events in Chat Room View when UI implementation type is used
Listens to UI-related events in Chat Profile View when UI implementation type is used
Listens to UI-related events in My Account View when UI implementation type is used
Listens to custom keyboard-related events when UI implementation type is used
Listens to events when a new/updated message is received by the application
Listens to changes to chat room's state in the room list
Listens to chat room status events such as typing events and online status
Listens to room list view controller lifecycle methods such as viewDidLoad, viewWillAppear, and many more.

TapTalkDelegate

General events such as notifications will be notified through TapTalkDelegate. A TapTalkDelegate instance is required when initializing TapTalk.
Note: Make sure to add #import <TapTalk/TapTalk.h> before registering the delegate
Objective-C
ViewController.m
//ViewController.m
#import <TapTalk/TapTalk.h>
//Add TapTalkDelegate declaration
@interface ViewController () <TapTalkDelegate>
@end
@implementation ViewController
- (void)function {
//Set TapTalk delegate to current
[[TapTalk sharedInstance] setDelegate:self];
}
#pragma mark - Delegate
#pragma mark TapTalk
- (void)tapTalkRefreshTokenExpired {
//Authentication is needed
}
- (void)tapTalkDidTappedNotificationWithMessage:(TAPMessageModel *_Nonnull)message fromActiveController:(nullable UIViewController *)currentActiveController {
//Handle tapped notification message
}
- (void)tapTalkUnreadChatRoomBadgeCountUpdated:(NSInteger)numberOfUnreadRooms {
// Returns number of unread messages from the application
}
- (void)tapTalkDidRequestRemoteNotification {
//Register for remote notification
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
@end
Method Name
Invoked When
tapTalkRefreshTokenExpired
User's refresh token has expired. Authentication with a new auth ticket is required.
tapTalkUnreadChatRoomBadgeCountUpdated:
The number of unread messages in the application is updated. Returns the number of unread messages from the application. Call method updateApplicationBadgeCount to update unread badge counter. You can see the function explanation in General section page.
tapTalkDidTappedNotificationWithMessage:
fromActiveController:
User tapped the notification.
tapTalkDidRequestRemoteNotification
TapTalk.io needs to request for push notification, usually client needs to add[UIApplication sharedApplication] registerForRemoteNotifications]inside the method.

Objective-C
- (NSArray<TAPCustomKeyboardItemModel *> *)setCustomKeyboardItemsForRoom:(TAPRoomModel * _Nonnull)room sender:(TAPUserModel * _Nonnull)sender recipient:(TAPUserModel * _Nullable)recipient {
NSMutableArray *customKeyboardItemArray = [NSMutableArray array];
TAPCustomKeyboardItemModel *customKeyboardItem = [TAPCustomKeyboardItemModel new];
customKeyboardItem.itemName = @"Item 1";
customKeyboardItem.iconURL = @"Item Icon URL 1";
[customKeyboardItemArray addObject:customKeyboardItem];
TAPCustomKeyboardItemModel *customKeyboardItem2 = [TAPCustomKeyboardItemModel new];
customKeyboardItem2.itemName = @"Item 2";
customKeyboardItem2.iconURL = @"Item Icon URL 2";
[customKeyboardItemArray addObject:customKeyboardItem2];
return customKeyboardItemArray;
}
