For Android, you only need to set userAgent attribute, for example:

For iOS, you need to add the code below inside the method didFinishLaunchingWithOptions (before the line return YES;) in AppDelegate.m implementation:

NSString *userAgent = @"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36";
NSDictionary *dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:userAgent, @"UserAgent", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];
