Identifying CEE Notifications

if ([[Smartech sharedInstance] isNotificationFromSmartech:(nonnull NSDictionary *)]) {
  
}
if Smartech.sharedInstance().isNotification(fromSmartech: [AnyHashable : Any]) {
  
}

Get GUID or Device token

If you need any additional information like device token or device GUID you can implement the following methods

[[Smartech sharedInstance] getDevicePushToken];
[[Smartech sharedInstance] getDeviceGuid];
Smartech.sharedInstance().getDevicePushToken()
Smartech.sharedInstance().getDeviceGuid()
SmartechSDK.getDevicePushToken((error, devicePushToken) => {
      //Grab the devicePushToken   
});

Debugging

To check the logs of CEE SDK, you need to implement a method named setDebugLevel in AppDelegate class in method didFinishLaunchingWithOptions.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  //...
  [[Smartech sharedInstance] setDebugLevel:SMTLogLevelVerbose];
  //...
  return YES;
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
  //...
  Smartech.sharedInstance().initSDK(withDelegate: self)
  Smartech.sharedInstance().registerForPushNotificationWithDefaultAuthorizationOptions()
  Smartech.sharedInstance().setDebugLevel(.verbose)
  //...
  return true
}

🚧

Note:

It is recommended to change the log level to SMT_LOG_LEVEL_NONE before uploading the app to the App Store.
