In my app, I require the main page to contain a toolbar at the top of the view. This view has a tableView. So my application cannot have a NavigationController.
Problem
When I want to navigate to the other view on click of the tableview cell then I am using the "pushViewController:animated:" method but it doesnt seem to work.
I checked the connections in IB. They are fine.
How can I navigate between pages without navigation controller??
I do not want to use the modal view for other views.
Please Suggest some Method.
You can use an instance of UINavigationController without having it displayed and using it for navigation.
Load your first view controller with your instance of UINavigationController in your appDelegate implementation.
Like:
FirstScreenController *fsc=[[FirstScreenController alloc]initWithNibName:#"FirstScreenController" bundle:nil];
UINavigationController *navigation=[[UINavigationController alloc]initWithRootViewController:fsc];
navigation.navigationBar.hidden=YES;
[window addSubview:navigation.view];
Here FirstScreenController can be your view controller having the toolbar and tableview.If you want to display another view on any click of the tableviewcell, call it this way.
[self.navigationController pushViewController:secondviewcontroller animated:NO];

I would like to combine UITableView and UINaviationController in an app but as a newbie most apps I've seen just send you straight to the results view (UITableView). But, I guess a "normal" search application does not assume you have the results on the first screen. There should be a search form on first screen with input fields and a button that triggers the search process and show some results and navigation.
So, I'm just trying to replicate this normal behaviour in my app. I've already made the search form (no navigation shown on it, of course) and a seperated View called "ListingViewController" with its related View and containing a UITableView and where I think I should add the Navigation...The next idea will be to make a DetailViewController and possibly and ListingMapController to show the listing in a GoogleMap.
So, where I'm stuck at is how to add this Navigation Controller ?
Some suggested me to add it in the SearchViewController delegate...
But I don't want a navigation on search form of course...
Some suggested me to open the Navigation controller modally...
But, I"m also planning at adding a Tab Bar to allow user to see other informations (like About,etc...) and with a modal Nav controller I don't know if they will still see the bottom Tabbar...
Any suggestions? What do you think is of best practices especially to avoid my app of being rejected by Apple?
Thx in advance for reading and helping!

You could init the navigationController with your View Controller as the root view Controller. Then hide the navigationBar (if you need to). You would then add the navigationController.view as the subview. This will basically look like the original view controller. Then you can pushViewController: animated: to push the results view Controller.
So, for example in your AppDelegate (or in the proper view controller):
Create a property and ivar for a UINavigationController and hook up its outlets in interface builder. Then set your search controller as the root view controller for the nav bar, and add it as a subview.
MySearchViewController* searchController = [[MySearchViewController alloc] init];
self.myNavigationController = [[UINavigationController alloc] initWithRootController:searchController];
[searchController release];
self.myNavigationController.navigationBarHidden = YES;
[self.window addSubview:self.myNavigationController.view];
[self.window makeKeyAndVisible];
Then of course in your searchController, you would simply say:
ResultsViewController* myResultsViewController = [[MyResultsViewController alloc] init];
//You may want to create another init method and pass in some arguments like an array:
// [[MyResultsViewController alloc] initWithResults:results];
then push the viewController
//This is in your search controller class
[self.navigationController pushViewController:myResultsViewController Animated:YES];
[myResultsViewController release];
from the results viewController, to get back you pop the view controller off of the navigationController view controller's stack.
//In results view controller perhaps in some IBAction for a back button:
-(IBAction)backButtonPressed:(id)sender
{
[self.navigationController popViewControllerAnimated:YES];
}
I have a simple uiviewcontroller with 4 buttons. Every buttonclick event loads a different image on the view. However for the 4th button i want to launch a navigation controller based uiview with a uitableview. The table view can then have 3 levels which define the settings for the application.
On selecting a row in the uitableview on the 3rd level i need to return to my main view with the selected row index.
How can i add a navigation based view which will be launched on a button press event and the first view of the uinavigationcontroller should compose of a back button which will close this navigation view and return to main view.
TIA,
Praveen S
Edit:
My first(home) view does not need a navigation bar. The view launched from the home view should however consist of a navigation bar with back button.
if(nxtv12==nil){
nxtv12=[[v12 alloc] initWithNibName:#"v12" bundle:nil];
}
[self.navigationController pushViewController: nxtv12 animated:YES];
and for coming back to home.
[self.navigationController popToRootViewControllerAnimated:YES];
Create a UINavigationViewController object in the current UIViewController (or use self.navigationcontroller) and push the new UIView into the navigation controller. To come back to the same view, use popToRootViewControllerAnimated in the new UIView class.
I have a tableView and want to add a new viewController so that when the user selects an item the new view shows an image and the bar at the top will allow the user to go back to the tableView.
This navigation bar at the top will be present in both views. Is it also possible to add a button e.g. share to it and link my own actions to the button?
Thanks.
Your tableView should live inside a UIViewController subclass that is itself inside of a UINavigationController. You can get this structure set up for you by selecting the "navigation-based" app in the project creation wizard. Or you can create this structure yourself in code. In your app delegate, create a UINavigationController, and set your app's first ViewController as the root view controller. Then pushing and popping view controllers is easy, just call:
MyDetailVC *vc = [[[MyDetailVC alloc] initWithNibName:#"MyDetailVC" bundle:nil] autorelease];
[self.navigationController pushViewController:vc animated:YES];
EDIT: so, to clarify, you don't "add navigation controllers to existing views," you "push and pop instances of your view controllers on to the navigation controller's stack."
I have created View based application, here i need to navigate between views when button pressed.
so in first view controller i have created action for button pressed.
-(IBAction)loadSecondView:(id)sender
{
SecondView *sView = [[SecondView alloc]initWithNibName:#"SecondView" bundle:nil];
[self.navigationController pushViewController:sView animated:YES];
[sView release];
}
this code is not working, anything i am missing,
i can do this by [self.view addSubview:sView]; but i need navigation effect.
Thanks in advance.
You can't just hook a UIView instance to a navigation controller, that's not how they work.
Take a look at the "Navigation-based Application" template in Xcode, to learn how navigation controllers work.
You can use view controllers while hiding the navigation bar:
[[self navigationController] setNavigationBarHidden:YES animated:NO];
You can then map UIButton instances to selectors that push or pop view controllers, while keeping the navigation bar hidden.
These button instances are subviews of the view controller's view property.
Hiding the navigation bar can help provide the illusion that you are not using a navigation controller, while giving you all the functionality of the navigation controller.
Alex is right, if you create just a "View Based Application" project, no UINavigationController was created so when you push something on it nothing happen, that's normal.
You have to create a UINavigationController and make you main view its rootViewController, then you can push on it a new viewController.
I have got a solution for this,
In View based application the appdelegate file creates object for, view controller and added that view to main window, to do our task, delete the controller in mainwindow.xib and add a UINavigation controller,and create a object to it, and connect outlet to it,and then add this navigation controller view as a sub view,
its work fine.
I have a view based app that works well. (In other words, I'm not going to start over with a Navigation-Based App template.)
It's an immersive app of sorts and I'm trying to add a Table View that loads in a new view when a button is pressed.
The loading the nib part works, but I can't seem to be able to add a navigation controller to the new view. I want to see a navigation bar on top with a done button and an edit button. Also, I want to the Table View entries to be empty.
I added a new file like so:
File-> New File -> UINavigationController subclass. I checked the UITableViewController Subclass and With XIB for user interface.
All I see when the view is pulled up is a blank Table View. I am able to customize things in the view controller.
What can I do to make the table show a navigation bar and be editable? I need some direction here please.
EDIT: I'm working with the latest Public SDK. (XCode 3.2.2)
The navigation bar usually comes with a navigation controller, not with the table view controller.
You can add the navigation bar manually, but that will require altering the table view, to change it to just a regular view with a table view inside of it, and changing your table view controller to be a regular view controller that manually handles the table view stuff.
The simpler alternative is to wrap your table view controller inside of a navigation controller before you display it. Something like:
MyTableViewController *myViewController = [[MyTableViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:myViewController];
[myViewController release];
//Now display navigationController instead of myViewController, using something like:
[self presentModalViewController:navigationController animated:YES];
