In my app, I've got a mainViewController that I'm trying to use for holding and controlling a couple of main view for my app. I first loaded up a splash screen, but then am wanting to have it so that when a user taps on the splash screen, they are taken to the main menu.
I've got the splash screen part working fine, but I'm having trouble with the NavigationController part.
[splashView.view removeFromSuperview];
mainMenu = [[menuScreenViewController alloc] initWithNibName:#"menuScreenViewController" bundle:nil];
mainMenu.title = #"Menu";
mainNavController = [[UINavigationController alloc] init];
[mainNavController pushViewController:mainMenu animated:NO];
[MAINVC.view addSubview:mainNavController.view];
[mainMenu release];
[mainNavController release];
[splashView release];
(MAINVC is defined elsewhere to be my main view controller).
Anyway, when I do this, I get the navigation controller with the title 'Menu', but the view contained in the mainMenu view controller do not show up in the navigation controller.
If I simply add the mainMenu's view ass a subview of MAINVC.view, it shows up correctly.
Any suggestions on how to get it to show up in my navigation controller?
avery, you're going to need to initialize the navigation controller with the mainMenu as its root view controller, instead of just initializing and then pushing a new view on. It needs that root view controller to work.
mainMenu = [[menuScreenViewController alloc] initWithNibName:#"menuScreenViewController" bundle:nil];
mainMenu.title = #"Menu";
mainNavController = [[UINavigationController alloc] initWithRootViewController:mainMenu];
//ADD MODAL SPLASH SCREEN HERE
[MAINVC.view addSubview:mainNavController.view];
[mainMenu release];
[mainNavController release];
[splashView release];
As the comment above shows, I'll suggest that you initialize this way, and then then add your splash screen to the nav controller as a modalViewController. This will prevent any delay you might have from the mainMenu initialization, when you tap the touchscreen. Then, when the modal view receives a touch, you can call:
[self.parentViewController dismissModalViewControllerAnimated:YES];

I've got a fullscreen view inside of a UINavigationController. When I attempt to present a modal view on top of it, the UINavigationBar changes to opaque, pushing down the content, before the modal view animates. How do I keep this from happening?
ContextMenuViewController *cmvc =
[[ContextMenuViewController alloc] initWithNibName:nil bundle:nil];
[cmvc setDelegate:self];
UINavigationController *navControl =
[[UINavigationController alloc] initWithRootViewController:cmvc];
[cmvc release];
[navControl.navigationBar setBarStyle:UIBarStyleBlackTranslucent];
[self.navigationController presentModalViewController:navControl animated:YES];
[navControl release];
[[UIApplication sharedApplication]
setStatusBarStyle:UIStatusBarStyleBlackTranslucent
animated:NO];
The UINavigationController's root view does not have any transparency (status bar nor UINavigationBar), only the pushed controllers have the transparency.
I created a video of the issue: http://www.youtube.com/watch?v=KSFvzTR5Ejk

I tried your code in a very small test project and didn't see the issue you describe. I suggest you do the same thing. Start with the Navigation-based Application template. In the main nib, check the navigation controller's Wants Full Screen and Resize View From Nib, and make its nav bar transparent. In the root view controller's nib, put a button that you can respond to, set up the action, and paste in your code. Create the ContextMenuViewController class; there is no need to give it a nib.
Run the app and press the button. The modal view slides into place, with a transparent nav bar, without affecting the transparency of the nav bar that already exists and without moving the existing content.
So now, once you've proved to yourself that it works in this simple project, it's just a question of locating what you're doing different from that in the real project.
Try setting the bar styles during viewDidLoad for the root View Controller.
HERE YOU GO )
OptionsViewController *detailViewController = [[OptionsViewController
alloc] initWithNibName:#"OptionsViewController" bundle:nil];
UINavigationController *optionsController = [[UINavigationController
alloc] initWithRootViewController:detailViewController];
[detailViewController release];
optionsController.navigationBar.translucent = YES;
optionsController.navigationBar.opaque = YES;
optionsController.navigationBar.tintColor = [UIColor clearColor];
optionsController.navigationBar.backgroundColor = [UIColor
clearColor];
optionsController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:optionsController animated:YES];
[optionsController release];
I have created a new Tab Bar Application template in xcode. How should I properly setup a new view that animates in (Slide Up) when a button is pressed? I've seen this done using the NavigationController.
I've added a navigation bar and a button with an action that adds a sub view using this code:
(IBAction)newPost:(id)sender
{
// Load UIViewController from nib
PostViewController *screen = [[PostViewController alloc] initWithNibName:#"PostViewController" bundle:nil];
// Add to UINavigationController's stack, i.e. the view for this UITabBarController view
[self.view addSubview:screen.view];
// Release music, no longer needed since it is retained by the navController
[screen release];
}
I'm not sure if this is what you're asking, but if you just want a new view controller to present itself modally upward just do this.
1.) New File --> View Controller
2.)
newViewcontroller *viewController = [[newViewcontroller alloc] initWithNibName:#"newViewcontroller" bundle:nil];
[self presentModalViewController:viewController animated:YES];
[viewController release];
I am relatively new to the whole MVC way of looking at things.
I have an application that is based on the "Utility" Application template. Everything in the MainView and FlipsideView is working great but now I need to add a TableView and Navigation Controller to the flipside. Without the navigation bar being on the MainView.
So only once the user has tapped the info light button will the nav bar display on the flipside with a table view.
I have been able to impliment the Table View on the side and populate it with data from an array.
I am now struggling to link in a navigation controller so that the tableview can become interactive.
When I place the nav bar code into the app delegate it appears on the MainView and not the flipside view.
Where do I place the navigation bar code so that it will display on the flipsideview. I cannt seem to get the code in the right place.
Also I am not sure I have the right code, do I put the UINavigationController code in the FlipSideViewController.m ?
I am not grasping the concept of the naivgation controller fully I think . . .
Here is the code to bring up the FlipView
- (IBAction)showInfo
{
TableViewController *controller = [[TableViewController alloc] initWithNibName:#"TableViewController" bundle:nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller animated:YES];
[controller release];
}
Now I need to get the TableViewController to have a navigation controller and a table view
Thanks in advance.
After you create your table view controller, create a navigation controller that contains this table view controller as the root. Then, present this navigation controller modally, instead of your table view controller.
I prefer to do this programmatically, so here's the code I use:
- (IBAction)showInfo
{
TableViewController *controller = [[TableViewController alloc] initWithNibName:#"TableViewController" bundle:nil];
controller.delegate = self;
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
[controller release];
navController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:navController animated:YES];
[navController release];
}
In your table view controller, set up its navigation item to contain a button that, when tapped, causes your main view controller to dismiss the modal navigation controller (thus flipping back to itself).
I have a view controller alike contacts in iPhone. The code is something like this,
tabBarController = [[UITabBarController alloc] init];
friendsVC = [[RemittanceFriendsVC alloc] initWithNibName:#"RemittanceFriendsView" bundle:nil];
friendsVC.friendsArray = [[RemittanceModel getInstance] friends];
UINavigationController *friendsNVC = [[UINavigationController alloc] initWithRootViewController: friendsVC];
[controllers addObject:friendsNVC];
tabBarController.viewControllers = controllers;
The RemittanceFriendsVC is UITableViewController, clicking on a cell takes to details view. I have 'modal' variable set in the ViewController (VC)to know if its loaded as modal or not. Since its part of a tab bar item, (non modal view) it works fine. But when I am loading it as modal VC, when I click on a table cell, I want to dismissmodalview, but it did not dismiss the modal view.
In the friendVC this is not working,
-(void) didPressCancelButton {
[self.navigationController dismissModalViewControllerAnimated:YES];
}
What I wanted to do is, use the same VC as a tab bar item and sometime as a modal VC. Isn't it possible?
okay, it was the problem with the
[self.navigationController dismissModalViewControllerAnimated:YES];
it should be,
[self dismissModalViewControllerAnimated:YES];
Then it works fine.
So, I'm having some issues with my implementation of the Three20 TTLauncherView. I am using their code, not a fork (although I have heard of rodmaz's version), and I can't get it to work properly. This is what my app looks like.

I removed the icon image, that's not the issue. The issue is, at the top there is no Navigation bar at all, and I believe also causes the white strip at the bottom, which appears to have the same dimensions as a Nav Bar. I've spent quite a while looking through their code and can't figure this out at all. It looks like their Navigation bar (as seen in their Catalog example app) stems from the TTTableViewController, or something further up. However, my app starts like the Facebook app does, not into a table, but into the TTLauncherView. So... how do I get the Navigation bar into my TTLauncher view, if it goes "App Delegate -> TTLauncherView Subclass"
Thanks for your help!
Edit:
Added the code I used. I put this in my app delegate, wrapping my first view with the UINavigation Controller, and it worked just as I wanted!
MainViewController *aController = [[MainViewController alloc] initWithNibName:nil bundle:nil]; //my Main view
self.mainViewController = aController;
[aController release]; //release for Memory Management
self.mainViewController.view.frame = [UIScreen mainScreen].applicationFrame;
UINavigationController *navigationController = [[UINavigationController alloc] init];
[navigationController pushViewController:self.mainViewController animated:NO]; //Gets the main view on the screen
[window addSubview:navigationController.view];
You simply wrap the view with a navigation bar before you push the new view. As an example, here is a snippet of my code where I present a modal view controller with a navigation bar.
- (IBAction) showNewNavView: (id) sender
{
// Present it as a modal view and wrap the controller in a navigation controller to provide a navigation bar for the Edit and Save buttons
ModalViewController *addController = [[ModalViewController alloc] initWithNibName:#"ModalViewController" bundle:nil];
addController.delegate = self;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addController];
navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
[self presentModalViewController:navigationController animated:YES];
[navigationController release];
[addController release];
}
If you want to add any buttons or set the title of it, you need to do that in the viewDidLoad method of the view that you are pushing (i.e. your TTLauncher view)
