This worked for me:
NSTimer *switchTo = [NSTimer scheduledTimerWithTimeInterval:0.1
target:selfselector:@selector(switchToTimer)userInfo:nil repeats:NO];
- (void) switchToTimer {
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPad" bundle:nil];
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:@"MyViewControllerID"]; // Storyboard ID
[self presentViewController:vc animated:FALSE completion:nil];
}
