This doesn't seem to be working. What am i doing wrong?
-(void)awakeFromNib{
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(showNewEventViewController)];
self.navigationItem.rightBarButtonItem = rightBarButtonItem;
NSLog(#"awaked");
[rightBarButtonItem release];
}
my guess is, that you add the UIBarButtonItem to the wrong object!
you need to add it, to the rootViewController (instead to the UINavigationController, as you probably did)
YourRootViewController *theRootController = [[YourRootViewController alloc] init];
UINavigationController* navContainer = [[UINavigationController alloc] initWithRootViewController:theRootController];
UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(dismiss)];
theRootController.navigationItem.rightBarButtonItem = btnCancel
[navContainer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:navContainer animated:YES];
I would normally put this code in the viewDidLoad method rather than the awakeFromNib method; I'm not sure if that's where your problem lies. What does "not working" mean?
Try this instead:
- (void) initUI {
UIBarButtonItem *btnCancel = [[[UIBarButtonItem alloc] initWithTitle:#"Cancel"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(dismiss)]autorelease];
self.navigationItem.rightBarButtonItem = btnCancel;
//[btnCancel release]; no need to explicitly release the item
}

I can't make my UIBarButtonItem to display. I simplified it as much as I could, but even this does not display the bar :
- (void)viewDidLoad {
UIBarButtonItem *supprBouton =[[UIBarButtonItem alloc]
initWithTitle:#"Supprimer"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(supprimerDate:)];
self.navigationItem.rightBarButtonItem = supprBouton;
UIBarButtonItem *enregBouton = [[UIBarButtonItem alloc]
initWithTitle:#"Enregistrer"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(enregFichier:)];
self.navigationItem.leftBarButtonItem = enregBouton;
[enregBouton release];
[supprBouton release];
}
One right button, one left, this should be displayed at least, no ? What can be wrong ?
Without more context, my best guess is that you have not yet set up a UINavigationController.
Try to add a uinavigationcontroller to your view:
UIViewController *vc = [[UIViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navCntrl1 = [[UINavigationController alloc] initWithRootViewController:vc];
I want to show next previous buttons above the keyboard. I call function "makeToolBars" from viewDidLoad to create it. The application does display the buttons correctly but when I click on them I get error it does not go to "goToNextField" function.
Can anyone point how to correct it ?
-(void)goToNextField:(id)sender
{
[txtPassword resignFirstResponder];
[txtUserName becomeFirstResponder];
}
-(void) makeToolBars
{
UIToolbar *toolbar1 = [[[UIToolbar alloc] init] autorelease];
[toolbar1 setBarStyle:UIBarStyleBlackTranslucent];
[toolbar1 sizeToFit];
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc]
initWithTitle:#"Next"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(goToNextField)];
UIBarButtonItem *flexButton1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
NSArray *itemsArray1 = [NSArray arrayWithObjects: nextButton,flexButton1, nil];
[flexButton1 release];
[nextButton release];
[toolbar1 setItems:itemsArray1];
[txtUserName setInputAccessoryView:toolbar1];
}
The below statement is wrong.
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc]
initWithTitle:#"Next"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(goToNextField)];
use the below modified correct code .
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc]
initWithTitle:#"Next"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(goToNextField:)];
Because you might forget to append colon in goToNextField (Correct goToNextField:).
And in your function implementation for goToNextField you were considering the colon and put :(id) sender in your function.
You've written action:#selector(goToNextField)];. It should be action:#selector(goToNextField:)];
I see that a similar question was asked here: How to add a right button to a UINavigationController? (among others) but its not quite what I'm looking to do and they arent solving my problem.
Essentially, I've created a UIViewController called WebViewViewController with a UIWebView on it which will be shown using presentModalViewController. Essentially its a mini web browser to display a web page while keeping the user in the app rather than launching Safari.
The viewController does the following to get it to show... and the "done" button is meant to provide a place to close the browser.
-(IBAction)visitFacebook {
WebViewViewController *rootController = [[WebViewViewController alloc] init];
rootController.webURL = #"http://www.facebook.com/";
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:rootController];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc ] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(done:)];
[navigationController.navigationItem setRightBarButtonItem:doneButton animated:YES];
[navigationController.navigationItem setTitle:#"Facebook"];
if (rootController) {
[self presentModalViewController:navigationController animated:YES];
}
[doneButton release];
[rootController release];
}
Unfortunately the "done" button isnt showing.. any ideas where im going wrong?
Try with below
-(IBAction)visitFacebook{
WebViewViewController *rootController = [[WebViewViewController alloc] init];
rootController.webURL = #"http://www.facebook.com/";
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:rootController];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc ] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(done:)];
rootController.navigationItem.rightBarButtonItem = anotherButton;
[navigationController.navigationItem setTitle:#"Facebook"];
if (rootController) {
[self presentModalViewController:navigationController animated:YES];
}
[doneButton release];
[rootController release];
}
Perhaps you're looking for something more like this:
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleDone target:self
action:#selector(dismissModalViewControllerAnimated:)];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStylePlain target:self action:#selector(done:)];
Just this one line code displayed done button for me.
I have a UIViewController which is created programmatically. I include the following code in loadView. The toolbar is shown, but not the button I added. Any help would be appreciated please.
[self.navigationController setToolbarHidden:NO animated:NO];
UIBarButtonItem *actionB = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:#selector(actionBTapped:)];
[self.navigationController.toolbar setItems:[NSArray arrayWithObject:actionB] animated:NO];
[actionB release];
You want to set the items on the UIViewController itself, not its navigation controller:
self.toolbarItems = [NSArray arrayWithObject:actionB];
Try this:
NSMutableArray *items = [[[NSMutableArray alloc] init] autorelease];
UIBarButtonItem *labelButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:nil action:nil] autorelease];
[items addObject:labelButton];
[items addObject:[[[UIBarButtonItem alloc] initWithTitle:#"YoutTitle" style:UIBarButtonItemStyleDone target:self action:#selector(actionBTapped:)] autorelease]];
[self.navigationController.toolbar setItems:items animated:NO];
I want set my custom method "Home" with RightNavagation button how should I?
My code
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithTitle:#"DontWorryAboutThis" style:UIBarButtonItemStylePlain target:self action:#selector(home:)];
[barButton setImage:[UIImage imageNamed:#"home_btn.png"]];
[self.navigationItem setRightBarButtonItem:barButton];
Know I want to link this method with it.
-(IBAction)home{
MainViewController *main=[[MainViewController alloc]
initWithNibName:#"MainViewController" bundle:nil];
[self.navigationController pushViewController:main animated:YES];
}
how should I Do this please help me out.
Try to change
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithTitle:#"DontWorryAboutThis" style:UIBarButtonItemStylePlain target:self action:#selector(home:)];
in
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithTitle:#"DontWorryAboutThis" style:UIBarButtonItemStylePlain target:self action:#selector(home)];
compare your selector #selector(home:) with your action -(IBAction)home
See the missing colon in your action?
Change your action to
- (IBAction)home:(id)sender
