I have a toolbar with 4 UIBarButtonItem's, on click of one of the buttons, i would like to change the current view controller to another view controller.
Could please tell me how i could achieve this??
Thanks,
BR,

Do you use UINavigationBar along with UIBarButtonItem?
If so, then just casual
[self.navigationController pushViewController:theViewCntrlrYouWant animated:NO];
should fit to your wish.
(Edited according to Suppi's observation)
If there's no navigation bar, then smth like:
YourViewController * first = [[YourViewController alloc] init];
[self presentModalViewController:first animated:NO];
[first release];

I have a basic doubt.I need to push viewController to another viewController .
and I am trying with code
Display1 *ac =[[Display1 alloc]init];
[[self navigationController]pushViewController:ac animated:YES];
this gives the option of navigation to previous stack.
I don't option to move on Previous Stack .for that reason I tried presentModalViewController
Display1 *ac =[[Display1 alloc]init];
[self presentModalViewController:ac animated:YES];
But this works fine this one does not give me option to but presentModalViewController Hides my UITabBarController
.is there anyway to, display UITabBarController with presentModalViewController.
or using pushViewController to not display previous stack
Darshana Is right If you dont want back option that use
self.navigationItem.hidesBackButton = YES;
before
[[self navigationController]pushViewController:ac animated:YES];
But if you want UITabBar at new UIViewController than you have to add that controller like this:
NextViewController *nextViewController=[[NextViewController alloc]initWithNibName:#"NextViewController" bundle:nil];
UINavigationController *navBar=[[UINavigationController alloc]initWithRootViewController:nextViewController];
[self.navigationController presentModalViewController:navBar animated:YES];
I have take this from PresentModalViewController not showing navigation bar on next view
But first decide what you want to use PUSH OR MODAL.
this both has different purpose.
I'm confused something fierce over having multiple views. I simply want to have a button on my main view that activates a new view, which in turn would have an (x) button which goes back to main view. For the life of me, I can't figure out how to do this with two separate .xib files. How might this be done?
Thanks!
It might be easiest to just use the utility application as a template.
From there, you can see how you would load view controllers and nibs in order to bring up the new view followed by how you would exit it.
I actually solved it by doing it this way:
NewViewController *new = [[NewViewController alloc] initWithNibName:#"NewViewController" bundle:nil];
new.delegate = self;
new.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:new animated:YES];
[new release];
You are using a navigation controller, right?
On the IBAction associated with a button tap on the main view, put
NewViewController *newView = ... // [alloc - init your view here if you haven't already]
[self.navigationController pushViewController:newView animated:YES];
And on the button on newView,
[self.navigationController popViewControllerAnimated:YES]
In my application the modal navigationcontroller that I am presenting is going under the current navigationcontroller so I'm not able to view the new navigationbar as it's disappearing under the current one.
I'm presenting the modalview on self and not self.navigationcontroller because self.navigationcontroller doesn't present the modalviewcontroller.
Also how to push a view on this modal navigationcontroller?
I'm using following code in one of my viewControllers:
fullListTopCompanies *fullListTopCompaniesInstance = [[fullListTopCompanies alloc] initWithNibName:#"fullListTopCompanies" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc]
initWithRootViewController:fullListTopCompaniesInstance];
fullListTopCompaniesInstance.navigationController.navigationItem.title = #"F";
[self presentModalViewController:navigationController animated:YES];
[navigationController release];
[fullListTopCompaniesInstance release];
Can anybody please help?
Thanx in advance.
use animated with transition
according to me you have to change the animation style
i done it before but forgot the code i will post it when i get it
self.navigationController.navigationItem.title = #"F";
Add the above line of code in viewDidLoad method of "fullListTopCompanies" class.
Actually your navigation bar hides because of the modal view and modal view by default doesnt have Navigation bar.To add a navigation bar to modal view you can try the below code:
In Header File
IBOutlet fullListTopCompanies *fullListTopCompaniesInstance;
In Implementation File
UINavigationController *nav = [[UINavigationController alloc] initWithNibName:#"fullListTopCompanies" bundle:nil];
[self presentModalViewController:nav animated:YES];
[nav release];
Also on the "fullListTopCompanies" View Controller dont forget to put a left navigation bar button item for dismissing the modal view.
So add that left bar button (Ideally Cancel Button on navigation bar) and event handler for that left barr button should contain the code
[self dismissModalViewControllerAnimated:YES];
Hope this helps.
I've used [[self navigationController] setTitle:#"Test Title"] to no avail. This is the same way I do it in the rest of my app. What could cause this?
Try setting the title of the navigation item.
self.navigationItem.title = #"Test Title";
Or like this if you prefer
[[self navigationItem] setTitle:#"Test Title"];
You are using the title property incorrectly, the navigationController has a title property because it inherets from UIViewController, the title property is used by NavigationControllers to display a title, so if you wanted the title you gave your NavigationController to show you would need to present it in another NavigationCOntroller...But what you need to do, is set the viewControllers that you are displaying titles instead of the NavigationController, now whenever u display that VC youll see the title in the navigation bar...
In short...the viewcontrollers title property is used by its navigationController to display the title on the navigation bar when that viewcontroller is on the top of the navigation stack...
CustomViewController *viewController = [[CustomViewController alloc] init];
[viewController setTitle:#"CustomViewController!";
[custonNavigationController pushViewController:viewController animated:YES];
This is a simplification of what Daniel had said. This method properly follows stack protocol.
SecondViewController *s1=[[SecondViewController alloc]initWithNibName:#"SecondViewController" bundle:nil];
[s1 setTitle:#"Second Page"];
[self pushViewController:s1 animated:YES];
Worked for me.
I've got a button on a view. When I click on it, it should load another view, one with a novigation controller. So far I've got this, the button calls this method:
-(IBAction)loadOptionsView:(id)sender {
if (self.optionsRootController == nil) {
//optionsRootController is declared as: UINavigationController *optionsRootController;
optionsRootController = [[UINavigationController alloc] init];
//Options is a UIViewController
Options *myOptions = [[Options alloc] initWithNibName:#"OptionsMenu" bundle:nil];
[optionsRootController pushViewController:myOptions animated:NO];
[myOptions release];
}
[self.view addSubview:optionsRootController.view];
}
What happens when I click the button is that it loads the xib file OptionsMenu on top of the current screen, but there's a gap at the top of the size of the status bar, so I can see the view below. Any help? What's the right method to load a new view that contains a navigation controller?
Thank you all!
I solved this issue by placing after:
[optionsRootController pushViewController:myOptions animated:NO];
this line:
[optionsRootController.view setFrame: [self.view bounds]];
Nice and easy!
I think UINavigationController's designated initializer is
- (id) initWithRootController:(UIViewController *)rootController
So your code above would be better expressed as
//optionsRootController is declared as: UINavigationController *optionsRootController;
//Options is a UIViewController
Options *myOptions = [[Options alloc] initWithNibName:#"OptionsMenu" bundle:nil];
optionsRootController = [[UINavigationController alloc] initWithRootController: myOptions];
[myOptions release];
Is the VIew in your nib the right size for the whole screen? Try turning off the simulated status bar in IB.
