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];

I want to add two buttons two navigation bar on right hand side one for settings and one for login but problem is that only one button i have searched comes on right that is edit is there any other way in which we can make two button and give them desired title.
UIBarButtonItem *addAttachButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(addAttachmentClicked:)];
UIBarButtonItem *sendButton = [[UIBarButtonItem alloc] initWithTitle:LS(#"Send") style:UIBarButtonItemStyleBordered target:self action:#selector(sendClicked:)];
self.navigationItem.rightBarButtonItems = #[addAttachButton,sendButton];
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)];
//add all buttons to right side
self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:backButton, fixedSpaceBarButtonItem,signIn_BarButton, nil];
}
now here are the metthods for both button clicks
-(IBAction)backTo:(id)sender{
[self.navigationController popViewControllerAnimated:YES];
}
-(void) signInUser{
//handle your sigin logic here
}
Please! let me if you need more help!
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
-(void)viewWillAppear:(BOOL)animated {
//setup toolbar
[self.navigationController setToolbarHidden:NO];
self.navigationController.toolbar.barStyle = UIBarStyleBlackTranslucent;
self.navigationController.toolbar.alpha = .8;
self.navigationController.toolbar.tintColor = [UIColor colorWithRed:6.0/255.0 green:95.0/255.0 blue:163.0/255.0 alpha:1];
//setup items
UIBarButtonItem *item1 = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self.navigationController.toolbar action:nil];
UIImage *imageUp = [UIImage imageNamed:#"up.png"];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithImage:imageUp style:UIBarButtonItemStylePlain target:self action:#selector(toggleUp:)];
item2.width = 5;
UIImage *imageDown = [UIImage imageNamed:#"down.png"];
UIBarButtonItem *item3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil];
UIBarButtonItem *item4 = [[UIBarButtonItem alloc] initWithImage:imageDown style:UIBarButtonItemStylePlain target:self action:#selector(toggleDown:)];
UIBarButtonItem *item5 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil];
UIBarButtonItem *item6 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(toggleDown:)];
UIBarButtonItem *item7 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
NSArray *itemsArray = [[NSArray alloc] initWithObjects:item1, item2, item3, item4, item5, item6, item7, nil ];
[self setToolbarItems:itemsArray];
...more
}
I am not sure what is happening here and I have read a lot about what to do for the toolbar but I cannot seem to get any of the UIBarButtonItems to display.
Any ideas?
Sorry for the messed up code above.
I have found the answer to my question.
I was accessing a child of the UINavigationController and not the root UIView.
I assigned the code above to the viewWillAppear to the root UIViewController of my UINavigationController and it worked. So to show it only on my sub UIViewController I had to set
[self.navigationController setToolbarHidden:NO];
To all the UIViewControllers that I do not want the toolBar to be visible on.
Hope this helps someone out. Thanks
How would I be able to set the position of a UIBarButtonItem? Like, I would like to set it to be on either the very right of a UIToolbar or the very left depending on a state.
Thank you.
You do not set directly the position of a UIBarButtonItem in an UIToolbar. Instead you defined the items' order and put flexible space on the left or on the right.
What you can do is:
Create the UIBarButtonItem you want to place (button 1).
Create an UIBarButtonItem of type UIBarButtonSystemItemFlexibleSpace (button 2).
If you want to put the button on the left, create an array with (button 1) and (button 2) and pass it to the UIToolbar by using the setItems:animated: method.
If you want to put the button on the right, create an array with (button 2) and (button 1) and pass it to the UIToolbar by using the setItems:animated: method.
I hope it helps you...
UIToolbar* keyboardDoneButtonView = [[UIToolbar alloc] init];
[keyboardDoneButtonView sizeToFit];
UIBarButtonItem* PrevButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:105 target:nil action:nil]; //<
UIBarButtonItem* NextButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:106 target:nil action:nil]; //>
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(doneClicked:)];
UIBarButtonItem* flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *fake = [[UIBarButtonItem alloc] initWithTitle:#"" style:UIBarButtonItemStylePlain target:nil action:nil] ;
