Navigation issue in Iphone SDK - iphone

Question

I have a view(HomeView) in which i open a popOver. The popoVer content View is (ListView) which contains a Table View.
Now, when i select the row, The HomeView will dismissed & open a new View(MapView).
Till now, It works fine. But my all views contain tabbar in xib. I don't have tab bar in ListView.
So, i just open MapView with present Modal View. But from that my navigation is not working.
My code is as following.
HomeView.m
//open popview with ListView
-(IBAction)btnTableMenu_TouchUpInside:(id)sender{
ListView *popUp=[[ListView alloc] initWithNibName:#"ListView" bundle:nil];
popView = [[UIPopoverController alloc]initWithContentViewController:popUp];
popView.delegate =self;
[popView setPopoverContentSize:CGSizeMake(300, 700)];
[popView presentPopoverFromRect:CGRectMake(150,25,20,50) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
ListView.m
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"DismissModal"object:self];
MapViewController *mapVC=[[MapViewController alloc]initWithNibName:#"MapViewController_ipad" bundle:nil];
[self presentModalViewController:mapVC animated:YES];
//[self.navigationController pushViewController:mapVC animated:YES];
}
How can i solve this??

Answer 1

you just do like this way:-
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"DismissModal"object:self];
MapViewController *mapVC=[[MapViewController alloc]initWithNibName:#"MapViewController_ipad" bundle:nil];
UINavigationController *navbar = [[UINavigationController alloc] initWithRootViewController:mapVC];
navbar.navigationBar.tintColor =[UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:0.1];
[navbar setModalPresentationStyle:UIModalPresentationFormSheet];
[navbar setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
[self presentModalViewController:navbar animated:YES];
}
in MapViewController.m file ViewDidLoad
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem *CancleButton = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(cancel)];
self.navigationItem.leftBarButtonItem = CancleButton;
}
-(void)cancel
{
[self dismissModalViewControllerAnimated:YES];
}

Answer 2

Do you know the difference btw ..
[self presentModalViewController:controller animated:YES];
& [self.navigationController pushViewController:controller animated:YES];
\When you do presentModalViewController:controller you lost the last Navigation stack.You need to create different navigationController for presenting the View. Read this properly you will get Idea .

Try following these-
ListView.m
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"DismissModal"object:self userInfo:[NSDictionary dictionaryWithObject:#"map" forKey:#"selectedView"]];
}
HomeView.m
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(dismissModal:) name:#"DismissModal" object:nil];
- (void) dismissModal:(NSNotification *)notification
{
[self dismissModalViewController:mapVC animated:NO];
if([[notification.userInfo valueForKey:#"selectedView"] isEqualToString:#"map"])
{
MapViewController *mapVC=[[MapViewController alloc]initWithNibName:#"MapViewController_ipad" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:mapVC];
[self presentModalViewController:navController animated:YES];
}
}
