How should I reload tableview content after switching containers. - caching

Question

I have a container view that can be switched between a tableview and a mapview when a user presses a UIButton. det determines which container view it is currently in.
- (IBAction)changer:(id)sender{
if(det == TRUE){
TableViewController *viewController2 = [[TableViewController alloc]init];
viewController2.view.frame = self.container.bounds;
[viewController2 willMoveToParentViewController:self];
[self.container addSubview:viewController2.view];
[self addChildViewController:viewController2];
[viewController2 didMoveToParentViewController:self];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.container cache:YES];
[UIView commitAnimations];
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 55, 35)];
[button setImage:[UIImage imageNamed:#"mapSwitch.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(changer:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *back = [[UIBarButtonItem alloc] initWithCustomView:button];
[self.navigationItem setRightBarButtonItem:back];
det = FALSE;
}
else{
ViewController *viewController1 = [self.storyboard instantiateViewControllerWithIdentifier:#"vc1"];
viewController1.view.frame = self.container.bounds;
[viewController1 willMoveToParentViewController:self];
[self.container addSubview:viewController1.view];
[self addChildViewController:viewController1];
[viewController1 didMoveToParentViewController:self];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.container cache:YES];
[UIView commitAnimations];
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 55, 35)];
[button setImage:[UIImage imageNamed:#"listSwitch.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(changer:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *back = [[UIBarButtonItem alloc] initWithCustomView:button];
[self.navigationItem setRightBarButtonItem:back];
det = TRUE;
}
}
The switching is just fine; it loads the tableview first which is populated correctly. Then, if you switch to the mapview, it is also fine. However, when I switch back to the table view and call a
[self.tableView reloadData];
method, the tableview is empty. Basically I have 2 arrays of info that need to be displayed on the tableview which return the correct information/content after switching back to the tableview, but do not appear in the tableview after reloaddata.
Is reloadData is not the best way to reload a tableview that was created before? I suspect that when the changer method reloads the tableview container, something is happening so there is nothing in the table view.
Or is there a way to "cache" the tableview so when you switch back to it, everything stays rather than reloading everything again?
