I would like to center a button in my navigationBar, which is currently defined as a rightBarButtonItem :
UIBarButtonItem *audioBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPlay target:self action:#selector(toggleAudioPlayback:)];
self.navigationItem.rightBarButtonItem = audioBtn;
[audioBtn release];
You can use the .titleView property of your navigation item - but you'll need to create your own assets for this (you won't be able to use a UIBarButtonItem). From Apple's docs:
...(titleViews) can contain buttons. Use
the buttonWithType: method in UIButton
class to add buttons to your custom
view in the style of the navigation
bar. Custom title views are centered
on the navigation bar and may be
resized to fit.

In my viewDidLoad method I have the following:
navigBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonSystemItemAction target:self action:#selector(btnClicked:)];
[self.view addSubview:navigBar];
The button does not show up at all! What am I missing?
// create the navigation bar and add it to the view
UINavigationBar *navigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
[self.view addSubview:navigationBar];
// create a button
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonSystemItemAction target:self action:#selector(btnClicked:)];
// create a UINavigationItem and add the button in the right hand side
UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle:nil];
navItem.rightBarButtonItem = button;
// add the UINavigationItem to the navigation bar
[navigationBar pushNavigationItem:navItem animated:NO];
set button on navigation bar .then u create a BarButtonItem on navigation.
barbutton=[UIBarButtonItem alloc] ]initWithTitle......
navigation.navigationController.rightBarButton= barbutton;
First read this :
When you use a navigation bar as a standalone object, you are responsible for providing its contents. Unlike other types of views, you do not add subviews to a navigation bar directly. Instead, you use a navigation item (an instance of the UINavigationItem class) to specify what buttons or custom views you want displayed. A navigation item has properties for specifying views on the left, right, and center of the navigation bar and for specifying a custom prompt string.
A navigation bar manages a stack of UINavigationItem objects. Although the stack is there mostly to support navigation controllers, you can use it as well to implement your own custom navigation interface. The topmost item in the stack represents the navigation item whose contents are currently displayed by the navigation bar. You push new navigation items onto the stack using the pushNavigationItem:animated: method and pop items off the stack using the popNavigationItemAnimated: method. Both of these changes can be animated for the benefit of the user.
So basically what you need to do is :
[navigBar pushNavigationItem:self.navigationItem animated:NO];
I have two table view controllers. Say TableViewController1 and TableViewController2.
I push TableViewController2 when someone clicks on the TableViewController1's cell.
I set the TableViewController1's clicked cell's value as the TableViewController2's back bar button's title value.
According to the length of the TableViewController1 cell's string, the back bar button's length also get changing.
Is it possible to fix the width of the back bar button? I really need this, because I want to capture the tap events of the TableViewController2 navigation bar's titleView.
Back bar button's width affects the titleView's width. So I can not find the bounds of the titleView. Or is there any other way to find the bounds value of a titleView of Navigation bar?
Is it possible to fix the width of the back bar button?
As far as I know you can not edit this button.
Subclassing it would be the way to go, or you might want to truncate the title from the previous viewController. Alternatively you might want to replace with with a normal UIBarButtonItem like so:
- (void) viewDidLoad
{
[super viewDidLoad];
self.title = #”shortTitle.”;
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:#"Back"
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
self.navigationItem.backBarButtonItem = backButton;
[backButton release];
}
Hi
i'm displaying UIBarButton on Navigation bar as back button,how can i've the default back button style for the UIButton.
Regards
Sam.
In the parent view controller when pushing the view in didselectrowInIndex method just use the following cod:
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStyleBordered target:self action:nil];
[self.navigationItem.backBarButtonItem release];
three20 includes a custom style for back-like buttons
You can use custom button with navigation button image.
Creating a left-arrow button (like UINavigationBar's "back" style) on a UIToolbar
What you are looking for can be done by making a custom UIButton
Hey, I am trying to add bar button items to my UINavigationBar (nav bar) but I have found out that bar button items are not properties of navigation bar and hence can't be accessed directly like:
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonSystemItemDone target:nil action:nil];
navBar.rightBarButtonItem =rightButton;
I am creating my navigation bar programmatically.
Apparently, there is something called UINavigation Item that has to be dealt with to add bar buttons. Can anyone tell me how to go about this? How to create this UINavigation item programmatically and add this to my navBar and then add the bar buttons to it.
UINavigationBars shouldn't be used on their own, outside of a UINavigationController.
When a navigation controller is used, each view controller on the navigation stack has a UINavigationItem. It is this UINavigationItem that you can add bar button items to.
self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonSystemItemDone
target:nil action:nil] autorelease];
I want to put an 'i' button on the nav bar (on all the screens in which the nav bar appears). Touching on that button should bring up a view (perhaps modal) in which I can have controls. How do I put the button on the nav bar, and what how will I execute the call back?
Info Button Code:
UIButton* infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[infoButton addTarget:self action:#selector(infoButtonAction) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *modalButton = [[UIBarButtonItem alloc] initWithCustomView:infoButton];
[self.navigationItem setLeftBarButtonItem:modalButton animated:YES];
[modalButton release];
The code above calls method -(void)infoButtonAction. Add this to all of your ViewControllers or just create one .nib and use that for all of your views.
You can also achieve it on storyboard.Drag a UIButton to you navigation bar instead of the usual UIBarButtonItem. You will see that your unbutton will be "nested" inside the bar button item which can be expanded.
Then you can change your button's type property to info light | dark from the attribute inspector.
