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.

want my table to show up only half way from the bottom of the screen, the upper half meant for the calendar view. To do this, I added a table view through code using CGRectMake specifying the (x,y) co-ordinates I wanted it to start at.
Now, I want each row of this table to navigate to a new view. How do I make the navigation controller push my new view? I added a navigation controller to my main view
TaskDetailsViewController *detailViewController = [[TaskDetailsViewController alloc] initWithNibName:#"TaskDetailsViewController" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES];
If you need to apply navigation from a view controller, that view controller should be a part of the navigation viewcontroller stack.
So what you have to do is instead of adding the rootViewController directly, You create a navigation controller, and set the rootViewcontroller to it(as rootViewController property). Once you set it, You can add navigation controller in place of rootViewController added previously.
Then on click you can use.
[self.navigationController push..... animated:..];
You can check it. If try to access the navigationController by self.navigationController currently it would be returning nil.
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 a simple tabBarController application where the user can navigate around 3 views.
In one of the views I have a UIButton that when touched moves the user to a fourth view. the problem is that the new view doesn't have the tab bar navigation visible.
what do I need to do to the fourth view to have it also use the tabBarController feature set.
thanks for any help
here's the code that transitions to the fourth view when a UIButton is touched:
-(IBAction) nextQuestion {
Question2 *q2 = [[Question2 alloc] initWithNibName:#"Question2" bundle:nil];
q2.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:q2 animated:YES];
[q2 release];
}
A modal view controller always takes up the entire screen. Its purpose is to provide a modal interface that does not let the user interact with other parts of the UI until they dismiss the modal view.
To display another view inside a tab, you could make the root controller of that tab a navigation controller. A button tap would then push the Question 2 controller on the nav controller's stack.
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];
My i have to develop simple window based iphone application.
In my first screen I design the UITabBarController with four TabBarButton.On first Tab screen contains three buttons.
When i click on of the button, the screen should navigate on simple tableView screen.But tableView screen the TabBarController should have be visible. Means simply first replacing with table view and move back to again previous one(The UITabBarController should be visible on all srceen).
Wrap your root view controllers in UINavigationControllers. Then, add the UINavigationControllers to the UITabBarController (so there should be 4 UINavigationControllers, one for each tab). When the button is clicked in the original view controller, do something like:
-(void) buttonClicked {
SimpleTableViewController *tvc = //etc
[self.navigationController pushViewController:tvc animated:YES];
[tvc release];
}
