I try to add a "add button" in the navigationBar, but the button who is created is a rectangle button with no text inside, not a "+" button, why?
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithTitle:#"" style:UIBarButtonSystemItemAdd target:self action:#selector(ajouterItem)];
self.navigationItem.rightBarButtonItem = addButton;
[addButton release];
You're mixing up the initializer with the one for title/style. You want this form:
- (id)initWithBarButtonSystemItem:(UIBarButtonSystemItem)systemItem target:(id)target action:(SEL)action
Call it like this:
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(ajouterItem)];

Here is the code I am using in My UIViewController's implementation file (.m file)
-(void)viewDidLoad{
[super viewDidLoad];
//back button
UIBarButtonItem *backButton = [[UIBarButtonItem alloc]initWithTitle:#" Back " style:UIBarButtonItemStyleBordered target:self action:#selector(backTo:)];
//Optional: if you want to add space between the back & login buttons
UIBarButtonItem *fixedSpaceBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
fixedSpaceBarButtonItem.width = 12;
//login button
UIBarButtonItem *signIn_BarButton = [[UIBarButtonItem alloc]initWithTitle:#" SIGN IN " style:UIBarButtonItemStyleBordered target:self action:#selector(signInUser)];

I am new at iOS Development.I Have UINavigationController as rootviewcontroller for UIWindow.In the subclass i added UITabbarController programatically.I given default Tabbarcontroller selection as first controller. Here i am trying to add 3 buttons to the navigationbar .
Can any send me the corrent code.
Thanks In advance
To add more than one button on the left or the right side you have to call one of the following methods:
- (void)setRightBarButtonItems:(NSArray *)items animated:(BOOL)animated
- (void)setLeftBarButtonItems:(NSArray *)items animated:(BOOL)animated
The array items contains instances of the UIBarButtonItem class. You can instantiate them like this
UIBarButtonItem *FirstButton = [[UIBarButtonItem alloc]
initWithTitle:#"Title"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(buttonTapped:)];
Then you have to implement the selector buttonTapped: which is called when the button has been tapped.
-(void)buttonTapped:(UIBarButtonItem *)button
{
// do the things that should happen when the button is pressed
}
If you don't want to get them on the left or right side it is also possible to create a UIView by yourself containing the buttons and set the view to be the titleView of the UINavigationItem. This effect is similar to the buttons in the Facebook App
[self.navigationItem setTitleView:yourView];
Here is simple code for add UIButton on UINavigationBar
In Following code you can add Button With FlexibleSpace
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
[barItems addObject:flexSpace];
[flexSpace release];
UIBarButtonItem *btnFirst = [[UIBarButtonItem alloc] initWithTitle:#"First" style:UIBarButtonItemStyleBordered target:self action:#selector(FirstTapped:)];
[barItems addObject: btnFirst];
UIBarButtonItem *btnSecond = [[UIBarButtonItem alloc] initWithTitle:#"Second" style:UIBarButtonItemStyleBordered target:self action:#selector(SecondTapped:)];
[barItems addObject:btnSecond];
UIBarButtonItem *btnThird = [[UIBarButtonItem alloc] initWithTitle:#"Third" style:UIBarButtonItemStyleBordered target:self action:#selector(ThirdTapped:)];
[barItems addObject: btnThird];
self.navigationItem.rightBarButtonItems = barItems;
Button Related Methods
-(void) FirstTapped:(UIBarButtonItem *)sender{
//perform your action
}
-(void) SecondTapped:(UIBarButtonItem *)sender{
//perform your action
}
-(void) ThirdTapped:(UIBarButtonItem *)sender{
//perform your action
}
NOTE : self.navigationItem.rightBarButtonItems Works only in iOS 5 or Latter.
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
// here is custom button setup //
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:customButton];
[self.navigationItem setLeftBarButtonItem:item animated:YES];
I have created navigation controller via storyboard interface and I have added 4 buttons programmatically on Navigationbar but I don't know how should I justify it would you please help me!
here is the picture:
here is my code for buttons I know That I used rightBarButtonItems but I don't know what should I write instead!
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem *menuButton= [[UIBarButtonItem alloc] initWithTitle:#"Menu" style:UIBarButtonItemStyleDone
target:self action:#selector(menu:)];
UIBarButtonItem *yearButton= [[UIBarButtonItem alloc] initWithTitle:#"Year" style:UIBarButtonItemStyleDone
target:self action:#selector(year:)];
UIBarButtonItem *weekButton= [[UIBarButtonItem alloc] initWithTitle:#"Week" style:UIBarButtonItemStyleDone
target:self action:#selector(week:)];
UIBarButtonItem *reportButton= [[UIBarButtonItem alloc] initWithTitle:#"Report" style:UIBarButtonItemStyleDone
target:self action:#selector(report:)];
NSArray *buttons = [NSArray arrayWithObjects:menuButton,yearButton,weekButton,reportButton,nil];
self.navigationItem.rightBarButtonItems = buttons;
}
Add flexible spacers between each of the buttons:
UIBarButtonItem *flexibleSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
how can i add buttons just beside a left barButton or just beside rightbarButton,
i mean i need to have more than 2 buttons on the title bar is that possible?
thanx in advance
You can use a view with two buttons in your leftBarButton -
UIBarButtonItem *leftBarButton = [[UIBarButtonItem alloc] initWithCustomView:leftBtnsView];
As drawn from this blog post:
Think of a toolbar as your container,
instead of the UIView object. And
since a UIToolBar is UIView based, it
can be added to the right side of a
nav bar using the above trick. The
following code shows how you can add
two standard buttons to the right
side:
// create a toolbar to have two buttons in the right
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 133, 44.01)];
// create the array to hold the buttons, which then gets added to the toolbar
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];
// create a standard "add" button
UIBarButtonItem* bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:NULL];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// create a spacer
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[buttons addObject:bi];
[bi release];
// create a standard "refresh" button
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refresh:)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// stick the buttons in the toolbar
[tools setItems:buttons animated:NO];
[buttons release];
// and put the toolbar in the nav bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
Also check the SO post
Adding buttons to navigation bar
I would suggest to use UISegmentedControl to hold all your buttons and use
[[UIButton alloc] initWithCustomView:] to show the segment control.
Here is a sample of how you could go about doing this. I am using a MasterDetailView template that comes with the top navigation bar for this example:
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] init];
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] init];
leftButton.title = #"Left button";
rightButton.title = #"right button";
self.navigationItem.leftBarButtonItem = leftButton;
self.navigationItem.rightBarButtonItem = rightButton;
}
You can do something like this, there's something called UINavigationItem.rightBarButtonItems
UIBarButtonItem *settingsButton = [[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:#"xxx.png"] style:UIBarButtonItemStyleDone target:self action:#selector(something)];
UIBarButtonItem *menuButton = [[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:#"xxx.png"]
style:UIBarButtonItemStyleDone target:self
action:#selector(something)];
self.navigationItem.rightBarButtonItems = #[settingsButton, menuButton];
i think you need something like this
UIBarButtonItem *firstButton = [[UIBarButtonItem alloc] initWithTitle:#"First" style:UIBarButtonItemStyleBordered target:self action:nil];
UIBarButtonItem *secondButton = [[UIBarButtonItem alloc] initWithTitle:#"Second" style:UIBarButtonItemStyleBordered target:self action:nil];
self.navigationController.navigationItem.leftBarButtonItems=#[firstButton, secondButton];
it will add two bar button items on left of navigation bar. you can make it on right side the same way
self.navigationController.navigationItem.rightBarButtonItems=#[firstButton, secondButton];
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
