For an OSX app I have the UI in a storyboard, with the initial controller being a NSWindowController with a NSWindow attach to it. It works just fine when the window is opened automatically, but I can't get it to work manually, which is needed as the window should only open based on a human interaction.
NSStoryboard *storyboard = [NSStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]];
NSWindowController *vc = [storyboard instantiateInitialController];
NSWindowController *windowController = [[NSWindowController alloc] initWithWindow:vc.window];
[windowController showWindow:nil];
[windowController.window makeKeyAndOrderFront:self];
[windowController.window makeMainWindow];
[NSApp activateIgnoringOtherApps:YES];
In a different project it does seem to work when the view controller is a separate XIB file, but in this case, it doesn't. I do see an empty, rectangular window appear briefly, so something is happening. Any ideas on how to get this to work?
Here your windowController object is local to the selecor, it is getting deallocated when the selector which contains the code is returned.
Make windowController, a property of the object which contains this code.

i want to change display to an UIViewController which has view controller at storyboard from an UIViewController class which hasn't got view controller at storyboard. There is no segue at storyboard for this...
Just like this:
In your AppDelegate.m do a quick setup:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
ViewController *sourceViewController = [[ViewController alloc] init];
UINavigationController * nav = [[UINavigationController alloc] initWithRootViewController:sourceViewController];
[self.window setRootViewController:nav];
return YES;
}
In above example replace ViewController class with your own class of sourceViewCntroller
- (IBAction) didPressMyButton {
NewViewController* newVC = [[[NewViewController alloc] init] autorelease];
[self.navigationController pushViewController:newVC animated:YES];
}
Connect this action to a button on storyboard or embed view change in any method. You will need to setup UINavigation controller first.
I'm not completely sure I understand what you're trying to do, but I think you are asking how to load a view controller from a storyboard, without using a segue, from a method in a view controller that wasn't loaded from the storyboard.
First, in your storyboard, select the view controller you want to load, and open the Identity Inspector. Set the Storyboard ID of the view controller. It looks like you want to load a MapViewController, so let's say you set the storyboard ID to map.
In your code, you can load the view controller like this:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
MapViewController *mapViewController = [storyboard instantiateViewControllerWithIdentifier:#"map"];
Once you have a reference to the view controller, you can set its properties or send it messages. You can then display it in whatever way you want - maybe by pushing it onto a navigation controller, or by presenting it, or by setting it as the root view controller of your window.
I have made a very simple Navigation based app (UIViewController). The view has a single button on the Main RootViewController.
Next, I made 2 classes: TabOneViewController, TabTwoViewController. All good. I then created a new Class TabBarViewController. I opened up the NIB file and dropped on a ``UITabBarController onto it. The two tabs it creates in it by default were assigned (respectively) to my TabOne and TabTwo view controllers.

Then in my TabBarViewController, I made an IBOutlet for a UITabBarController, synthesized it etc etc. I linked it up in Interface builder via the "files owner".
In the RootViewController, I linked the button to my "pushView" method, and in this pushView method, I have the following code:
- (IBAction) pushView {
TabBarViewController *controller = [[TabBarViewController alloc] init];
[self.navigationController pushViewController:controller animated:YES];
[controller release];
}
The end result is it DOES push a view, but I cannot see the tab bar at the bottom, let alone any of the pages I've added to the controller.
What am I doing wrong? Why can't I link it in IB?
I am not 100% sure if that's allowed.. because you already have one tabBarController as rootViewController, and you dropped one more tabBarController as first tab controller, tabs ll overlap, considering amount of real estate you have on your iPhone, it make sense to not allow a tabViewController inside another
First, you need to allocate your view controller with your nib:
TabBarViewController *controller = [[TabBarViewController alloc] initWithNibName:#"YourNibName" bundle:nil];
Secondly, in IB, click the UITabBarController and go to the identity inspector and make sure you select your custom class. That said, unless you are overriding or adding some functionality you probably don't need the custom class at all, simply use a UITabBarController directly:
UITabBarController *controller = [[UITabBarController alloc] initWithNibName:#"YourNibName" bundle:nil];
Imagine that we have multiview apllication which is controlled by Navigation Controller. We go from the first view to second by using pushViewController method and that's not a problem but then we need to move to the third view. And the third one is a view which looks like a TabBar. How do we do that? The third view is supposed to be controlled by TabBarController, isn't it?
So how to pass the control? I declared an outlet UITabBarController * tbc and connected it to TabBarController in xib file and then i tried this in viewDidLoad:
tbc = [[UITabBarController alloc]init];
and it shows nothing.
Your help is highly appreciated
It's a bit wierd. Its more standard to have a tabBarController that switches views and some of those views may be navigation controllers. But ...
Create the UITabBarController and push it.
NSMutableArray *viewControllers = [[NSMutableArray alloc] init];
// create someView
[viewControllers addObject:someView];
// create someView2
[viewControllers addObject:someView2];
UITabBarController *tabController = [[UITabBarController alloc] init];
[tabController setViewControllers:viewControllers];
[[self navigationController] pushViewController:tabController animated:YES];
Then, from the tabBarContoller view, based on some action, you can choose to pop it:
[self.navigationController popViewControllerAnimated: NO];
You can wire it up in the storyboard editor in the latest version of Xcode.
However, since this is very much non-standard use of the controls, you would need a very good reason as to why you would want a UI like this.
And even then, Apple's review process might turn your app down if the interface is clunky.
I am in the appdelegate of my application. How can I add a modal view controller in the "didfinishlaunching" method?
I tried the following but did not work
SomeViewController *vc = [[SomeViewController alloc]init];
[self.tabController.navigationController presentModalViewController:vc animated:NO];
EDIT:
I changed my implementation to the following
self.tabController.selectedViewController
= [self.tabController.viewControllers objectAtIndex:0];
SomeViewController *vc = [[SomeViewController alloc]init];
[self.tabController.selectedViewController presentModalViewController:vc animated:NO];
I checked that the 'selected view controller' is not null... however I am still not able to get the output I needed. Is there anything I am missing?
Assuming tabController and navigationController are not nil, the applicationDidFinishLaunching may be too soon to display the modal view controller.
Make sure you put that code after you make the window key and visible. [self.window makeKeyAndVisible];
If that does not work try listening for the UIWindowDidBecomeKeyNotification for that window
You can try delaying presentation of that modal a few seconds using performSelector:withObject:afterDelay:
In my app, I have three views. Originally, the appDelegate opened the xib file for the mainViewController, and the preset settings on my application template included a flipsideViewController, which would be shown when an information button was hit.
Later I decided to include another view controller and xib file, called CountySelectionViewController. The xib file has a button that opens the xib file for the mainViewController via the following:
MainViewController *controller = [[MainViewController alloc] initWithNibName:#"MainView" bundle:nil];
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller animated:YES];
[controller release];
Should I use the same thing to go back to the CountySelectionViewController as well as its xib? or is there a better way?
I believe what you're looking for is dismissModalViewControllerAnimated: -- http://developer.apple.com/iphone/library/documentation/uikit/reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/instm/UIViewController/dismissModalViewControllerAnimated:
