Event Delegate

MeetTalk iOS SDK listens to various events on the client app. The event delegate MeetTalkDelegate replaces the usage of TapTalkDelegate from PowerTalk iOS SDK and also contains all the callbacks that TapTalkDelegate has.

All other delegates from PowerTalk SDK can still be implemented normally.

MeetTalkDelegate

MeetTalkDelegate notifies general events from PowerTalk SDK and call/conference related events from MeetTalk SDK.

Not all of the delegate callbacks are required to be handled, but we strongly suggest to override tapTalkRefreshTokenExpired to handle authentication when the user's session has expired.

Note: Make sure to add #import <MeetTalk/MeetTalk.h> before registering the delegate

Objective-C

#import <MeetTalk/MeetTalk.h>

@interface AppDelegate() <MeetTalkDelegate, ...>

...

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [[MeetTalk sharedInstance] initWithAppKeyID: ...
  }];
  [[MeetTalk sharedInstance] setDelegate:self];
}
