I want to create three buttons in right side of Navigation bar.I am using storyboard for creating the UIView Controller.
In DetailViewController am Embedded a Navigation bar using storyboard and then creating three UIBarButtonItem programetically and then adding these in an array then assigning it to navigationitem.This is working fine.
UIBarButtonItem *Button1 = [[UIBarButtonItem alloc]initWithTitle:#"Button1" style:UIBarButtonItemStylePlain
target:self action:#selector(Button1Clicked:)] ;
UIBarButtonItem *Button2 = [[UIBarButtonItem alloc] initWithTitle:#"Button2" style:UIBarButtonItemStylePlain
target:self action:#selector(Button2Clicked:)] ;
UIBarButtonItem *Button3 = [[UIBarButtonItem alloc] initWithTitle:#"Button3" style:UIBarButtonItemStylePlain
target:self action:#selector(Button3Clicked::)] ;
self.navigationItem.rightBarButtonItems =
[NSArray arrayWithObjects:Button1,Button2,Button3, nil];
I have another viewcontroller this is a modalviewcontreoller. I am creating the view controller using storyboard and adding a navigationbar not a navigationcontroller.Then using the same method for adding buttons to navigtion bar, but not shown any buttons.
Plese anyone know how to solve this issue.?
If your viewController is in UINavigationController you can simply use
self.navigationItem ...
which works fine as I see. But if your viewController (your modal in this case) is not in UINavController, you have to access UINavigationItem in this way:
someNavigationBar.topItem ...
So, if you set an IBOutlet to your navigationBar, your code should look like this one:
UIBarButtonItem *Button1 = ...
UIBarButtonItem *Button2 = ...
UIBarButtonItem *Button3 = ...
yourNavigationBar.topItem.rightBarButtonItems = [NSArray arrayWithObjects:Button1, Button2, Button3, nil];
Please add UINavigationBar instead of UINavigationItem

I am in great trouble....How can i set next and previous button/arrow at my segmented bar...if anyone need brief about my problem then please see this link...How can i add a next and previous button at the segmented Controller?
i have attached an image to understand the problem...so anybody help me please....
NOTE THAT: In my current project it has more than 5 buttons to add at the segmented bar so when i will press next/previous arrow then segmented bar should be move from his place.If my question is not clear to you then please see my another link....
Thanks in Advance
EDIT:
UIBarButtonItem *previousBarButtonItem = [[UIBarButtonItem alloc] //init];
initWithTitle:#"<"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(previousBarButtonAction:)];
self.navigationItem.leftBarButtonItem = previousBarButtonItem;
[previousBarButtonItem release];
UIBarButtonItem *nextBarButtonItem = [[UIBarButtonItem alloc] //init];
initWithTitle:#">"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(nextBarButtonAction:)];
self.navigationItem.rightBarButtonItem = nextBarButtonItem;
[nextBarButtonItem release];
//This Portion For UIToolbar
topToolBar = [UIToolbar new];
topToolBar.barStyle = UIBarStyleDefault;
[topToolBar sizeToFit];
topToolBar.frame = CGRectMake(50, 410, 280, 50);
//Add buttons
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
target:self
action:#selector(pressButton1:)];
UIBarButtonItem *systemItem2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction
target:self
action:#selector(pressButton2:)];
UIBarButtonItem *systemItem3 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCamera
target:self action:#selector(pressButton3:)];
//Use this to put space in between your toolbox buttons
UIBarButtonItem *flexItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
//Add buttons to the array
NSArray *items = [NSArray arrayWithObjects: systemItem1, flexItem, systemItem2, flexItem, systemItem3, nil];
//release buttons
[systemItem1 release];
[systemItem2 release];
[systemItem3 release];
[flexItem release];
//add array of buttons to toolbar
[topToolBar setItems:items animated:NO];
self.navigationItem.titleView = topToolBar;
this is my current coding position now i have 4 buttons in the uitoolbar but only 3 button can see so i want to move this toolbar when i will press next or previous button to see the others button whose are out of frame of uitoolbar??
EDIT:
I able to scroll the navigation bar item using uiview animation but now my problem is when i press the next/prev button then it is moving from the current place according to the changing of the coordinate of the uitoolbar and moving over the pre/next baritem frame whose are not in the uitoolbar items. but it should be wothin a uiview and should change the coordinate within the uiview not out of the view...now tell me what can i do for this problem.
Firstly in figure the NavigationBar you are seeing is actually UIToolBar. Unfortunately it is not possible to add anymore controls on the UINavigationBar. But you can achieve exactly same UI with UIToolBar where you can add any controls.
So to achieve this use UIToolBar and not UINavigationBar. Also use UIBarButtonItem with custom title to achieve Next and Previous functionality.
EDIT
Here are few links for example of UIToolBar
http://www.codeproject.com/Articles/43658/How-to-Make-a-Toolbar-with-UIToolbar
http://osmorphis.blogspot.com/2009/05/multiple-buttons-on-navigation-bar.html
http://atastypixel.com/blog/making-uitoolbar-and-uinavigationbars-background-totally-transparent/
But this all explains using codes. Instead using Interface Builder, it becomes too easy to use UIToolBar (if coding is not so important).
I think this is being slightly overcomplicated- can you not just set the text of the two UIBarButtonItems to "<" and ">"?
as my title, how do i add in a rightbarbuttontiem in a specific view of tabbarcontroller ?
i'm using storyboard to create the tabarcontroller.
i tried this but the item are not displayed
UIBarButtonItem *settingButton = [[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:#"gear.png"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(pushToSetting)];
//BarButtonItem *settingButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(insertNewObject)];
self.navigationItem.rightBarButtonItem = settingButton;
Are you using a NavigationController? If you are, then your code should work. If you are using just a UINavigationBar, then you have to set the items property for the UINavigationBar. As you are not getting a rightbuttonitem, I assume you are using a UINavigationBar. This code should work:
UIBarButtonItem *settingButton = [[UIBarButtonItem alloc] initWithTitle:#"Settings" style:UIBarButtonItemStylePlain target:self action:nil];
UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle:#"Test"];
navItem.rightBarButtonItem = settingButton;
NSArray *navItems = [NSArray arrayWithObject:navItem];
[self.navBar setItems:navItems];
You should have the rightbarbuttonitem now. Here, navBar is a UINavigationBar outlet. You can also pop and push navigation items onto a UINavigationBar using these methods:
(void)pushNavigationItem:(UINavigationItem *)item animated:(BOOL)animated;
(UINavigationItem *)popNavigationItemAnimated:(BOOL)animated;
I'm looking at some other iPad apps that have the capability to add extra icons into the leftBarButtonItem and rightBarButtonItem for UINavigationController. Here is a picture of one taken from nngroup.com:
In order to do something like this, are they subclassing UINavigationController or adding a category for it? Or are they doing something different? I kind of just wanted the general approach of how to do something like this, but don't need all the code since I'm sure it's a lot of work. Thanks.
You can create a toolbar object and add the buttons to that toolbar and then set the custom view of the right bar button item or left bar button item as this toolbar.
A sample implementation is like this.
UIToolbar * toolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0,0,160, 44.5)];
UIBarButtonItem *spacer = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
[buttons addObject:spacer];
[spacer release];
UIBarButtonItem * deleteButton = [[UIBarButtonItem alloc]
initWithTitle:#"Delete"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(deletePressed)];
// Button style is the default style
[buttons addObject:deleteButton];
[deleteButton release];
UIBarButtonItem * barItem = [[UIBarButtonItem alloc] initWithTitle:#"Logout" style:UIBarButtonItemStyleBordered
target:[Y3AppDelegate mainApplicationInstance] action:#selector(logout)];
[buttons addObject:barItem];
[barItem release];
// put the buttons in the toolbar and release them
[toolbar setItems:buttons animated:YES];
[buttons release];
// place the toolbar into the navigation bar as Right Button item
self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc]
initWithCustomView:toolbar] autorelease];
[toolbar release];
One thing to note here is that you may have to change the tint color of the toolbar to match with that of the navigation bar. Hope this answer helps you.
You can hide Navigation bar and instead of that show an image of navigation bar and then place buttons on it :))
I've seen a few different posts on this, but I can't seem to get it working. I basically have a UITableView and want sort buttons at the top of a popover controller. I followed this post: UIPopoverController toolbar at top in order to get started. In my controller that is the rootViewController of the navigationController, I can create a UISegmentControl and place it at the top. However, it does not look like the picture in that it's not centered. Maybe because the way I get it into the popover is in the viewDidLoad of the popover like this:
UISegmentedControl *topSegmentControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"One", #"Two", #"Three", #"Four", nil]];
topSegmentControl.backgroundColor = [UIColor clearColor];
topSegmentControl.segmentedControlStyle = UISegmentedControlStyleBar;
UIBarButtonItem *toolBarCustom = [[UIBarButtonItem alloc] initWithCustomView:topSegmentControl];
// UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
self.navigationItem.leftBarButtonItem = toolBarCustom;
Also, if I want to present data at the bottom of the popovercontroller in a toolbar, I'm not sure where to do that. Following the same example: UIPopoverController toolbar at top, I thought in my navigationController, I would do something like this:
UISegmentedControl *topSegmentControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"BottomOne", #"BottomTwo", #"BottomThree", nil]];
// topSegmentControl.backgroundColor = [UIColor clearColor];
topSegmentControl.segmentedControlStyle = UISegmentedControlStyleBar;
UIBarButtonItem *toolBarCustom = [[UIBarButtonItem alloc] initWithCustomView:topSegmentControl];
UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
NSArray *array = [NSArray arrayWithObjects:spaceItem, toolBarCustom, spaceItem, nil];
[navController setToolbarItems:toolBarCustom];
[navController setToolbarHidden:NO];
When I try this, I see a toolBar with nothing in it, that is a lighter tint than the rest of the popover.
To summarize, I'm not sure as to where you would initialize toolbar or barbuttonitems for a popover that has a navigationcontroller like in the example. I'm also not sure how to center the data. Thanks.
You’ll probably be best suited by just setting your UISegmentedControl as the titleView of your root view controller’s navigationItem.
I have a UIToolBar that is created in XCode. In it, there is a UISegmentControl. Based on when one action is pressed, a new view is added as a subView that has a UIToolBar, but without the UISegmentControl. On this view, I add a UIBarButtonItem to go back that looks like this:
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStyleBordered target:self action:#selector(GoBack)];
NSArray *barItems = [NSArray arrayWithObject:backButton];
[self.MainToolbar setItems:barItems];
[backButton release];
How do I remove this UIBarButtonItem once my selector(GoBack) is called? I assume I put the code in that method to remove the UIBarButtonItem. I tried this, but it did not work.
[self.MainToolbar setItems:[NSArray arrayWithObject:nil]];
I wasn't sure how to remove it, and how or if this affects the UISegmentControl that is in the UIToolBar created in the .xib.
I have seen code about using the navigationItem, but I'm not sure how the UIToolBar relates to the navigationItem as well. Thanks!
