how to create a web view stop button programmatically - iphone

i want to add a button to toolbar of webview without using IB ,so i must do it using programmatically how to do it?

I haven't tested this, but it should be close. It adds a button named "Stop" to the right side of a toolbar. You'd call this method from the viewDidLoad method of your view controller.
- (void)setUpToolbar
{
UIBarButtonItem* flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
UIBarButtonItem* stopButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Stop"
style:UIBarButtonItemStylePlain
target:self
action:#selector(stopButtonAction:)];
NSArray* items = [[NSArray alloc] initWithObjects:flexibleSpace, stopButtonItem, nil];
[stopButtonItem release];
[flexibleSpace release];
[toolbar setItems:items animated:NO];
[items release];
}
- (void)stopButtonAction:(id)sender
{
// ... do something ...
}

How to add UIButtons to navigationbar ,the class also consists UITabbarController

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];

uitoolbar in navigation bar.

this is a simple problem, but i'm new to xcode dev. I followed a guide online to have multiple buttons on a navigation bar. the edit button on the navgivation bar has a IBAction method called "editButton". which has a (id)sender as parameter. do I get the sender and change the text from edit to done, done to edit?
"UIBarButtonitem *bbi = (UIBarButonItem *) sender;" doesn't seem to be working. how do i get the button in the toolbar in navigationbar?
Thank you.
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 "EDIT" button
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:#selector(editButton:)];
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];
-(IBAction)editButton:(id) sender{
UIBarButtonitem *bbi = (UIBarButonItem *) sender;
if (bbi title isequalsString:#"Done){
[bbi setTitle:#"Edit"];
}
}else{
[bbi setTitle:#"Done"];
}
}
The trouble is that you have used a UIBarButtonSystemItemEdit, not a standard uibarbutton.
Try creating it with:
bi = [UIBarButtonItem alloc] initWithTitle:#"Edit" style: UIBarButtonItemStyleBordered target:self action:#selector(editButton:)];
Then use the rest of the code as is.
UIBarButtonSystemItemEdit is a special bar button item that takes care of the "Edit / Done" states for you. No need to manually change the button's text.

how to add a button beside left bar controller or right bar controller

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];

Buttons don't appear on the toolbar

A simple question. How do I add toolbar items in combination with a TTLauncherViewController. I must do something very basic wrong, as the toolbar appears, but the button does not show:
self.navigationController.toolbarHidden = NO;
self.navigationController.toolbar.tintColor = [UIColor blackColor];
UIBarButtonItem *updateBttn = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
target:self
action:#selector(updateData:)];
UIBarButtonItem *btnSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil ];
self.navigationController.toolbarItems = [NSArray arrayWithObjects:updateBttn, btnSpacer, nil];
[btnSpacer release];
[updateBttn release];
Could this be the issue?
http://www.iphonedevsdk.com/forum/iphone-sdk-development/22180-navigationcontroller-toolbar-wont-show-any-buttons.html
In short, it says that the toolbar is not a child of the navigation controller but the parent view.
