When I create and add a UIToolBar and UIBarButton items, how can I get the toolbar and items to appear properly in both orientations. This is what I have so far:
self.toolbar = [[[UIToolbar alloc]initWithFrame:CGRectMake(0, 372, 320, 44)]autorelease];
self.toolbar.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.deleteButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemTrash target:self action:#selector(deleteButtonClicked)] autorelease];
self.deleteButton.style = UIBarButtonItemStylePlain;
UIBarButtonItem *flexibleSpace = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil] autorelease];
self.shareButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:#selector(shareButtonClicked)] autorelease];
self.shareButton.style = UIBarButtonItemStylePlain;
self.navigationItem.leftBarButtonItem = backItem;
NSArray *toolbarItems = [NSArray arrayWithObjects:self.shareButton,flexibleSpace,self.deleteButton,nil];
[self.toolbar setItems:toolbarItems animated:NO];
As you can see from the images, the UIBarButtonItems look correct in portrait, but weirdly squished and off center (especially the trash icon), in landscape. Is there an obvious solution I'm missing, or do I have to do manual resizing to get this right?
It's a subtle difference, but here's what it should look like:
You have to look at the Autoresizing option in the Size inspector both for the UIToolBar and the buttons. UIToolBar might also have a checkmark set for Autoresize subviews uncheck that so it does not influence your buttons.
The answer, at least until iOS 5 is to use the UINavigationController's built in toolbar instead of creating your own. The built in toolbar will resize correctly and automatically.

I need to add a button to the center of the ToolBar. I have done the adding the button to the toolbar part successfully. My problems are as follows;
1.) I need to center this barbutton. It should be in the center of the Tool Bar
2.) I need to have a text after the refresh button image is displayed.
toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0 , 320 , 60)];
NSMutableArray* button = [[NSMutableArray alloc] initWithCapacity:1];
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refreshButtonAction:)];
[button addObject:barButton];
[toolBar setItems:button animated:NO];
[self.view addSubview:toolBar];
1. Add flexible spacers before and after your bar button in the toolbar items array:
toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0 , 320 , 60)];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refreshButtonAction:)];
NSArray *toolbarItems = [NSArray arrayWithObjects:flexibleSpace, barButton, flexibleSpace];
[toolBar setItems:toolbarItems animated:NO];
[self.view addSubview:toolBar];
Configuring toolbars is much easier to do in Interface Builder. If your view controller is inside a UINavigationController stack, you can still use IB to create an outlet collection of UIBarButtonItems and set self.toolbarItems in -viewDidLoad.
2. To get custom content in a toolbar you can create a bar button item with a custom view:
UIView *customView = <# anything, could be a UILabel #>;
UIBarButtonItem *customItem = [[UIBarButtonItem alloc] initWithCustomView:customView];
I know this can be done in IB, but I believe if you want to center a button, you will need to add a fixed or flexible space button on either side to keep your button in the middle. If you are going to do this with just code... try and sandwich your button between the 2 space buttons.
I want to create a UIToolbar that will add it´s buttons from an array. Or perhaps a segmented control.
The problem is that i don´t know before hand how many buttons or segments I need and also if its more than, say 4-5 buttons I want to be able to scroll or similar horizontally for display more buttons.
I want to be able to have multi selection so which approach would be the best to take for this?
A tableViews content will be based on the selection of the buttons on the toolbar.
Any tips for how I can make this work? or a recommendation for a tutorial out there regarding this would be much welcomed.
Thanks in advance!
UIBarButtonItem *btnAdd = [[[UIBarButtonItem alloc] initWithTitle:#"Add"

How can i rotate a uibarbuttonitem inside a uitoolbar? Because I rotated the uitoolbar (it's vertical now) and my bar button items are rotated too but i dont want that.
thanks
UIBarButtonItem does not extend UIView, so it cannot be transformed directly. You can add the UIBarButtonItem you wish to transform to a UIToolbar, transform the UIToolbar and then add the toolbar as a custom view to another UIBarButtonItem. This item can then be set as a navigation item or added to another UIToolbar.
UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPlay target:self action:#selector(handleForwardItemTouch:)];
UIToolbar *backToolbar = [[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 44, 44)] autorelease];
[backToolbar setTransform:CGAffineTransformMakeScale(-1, 1)];
UIBarButtonItem *backToolbarItem = [[[UIBarButtonItem alloc] initWithCustomView:backToolbar] autorelease];
self.navigationItem.rightBarButtonItem = backToolbarItem;
i've seen a "Previous/Next/Done" bar above the keyboard when entering text in a webview on an iPhone. i want to use this built in bar in an app that i'm making in conjunction with a UITextView. i have seen a very similar looking bar above the keyboard in several apps. my guess is this is either some hand made bar that just looks like the bar i want or the programmer figured out a way to show the actual bar. assuming its the actual bar and not a hand made bar how do you get it to display?
There's no built-in Prev/Next/Done bar, you have to create it yourself.

How to find out what UITextField caused a UIKeyboardWillShowNotification?
I wrote XCDFormInputAccessoryView which is an input accessory view with previous/next/done buttons.
Create this method and call it on ViewWillLoad:
- (void) keyboardToolbarSetup
{
if(self.keyboardToolbar==nil)
{
self.keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 44)];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStylePlain target:self action:#selector(anyAction)];
UIBarButtonItem *extraSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(anyOtherAction)];
NSArray *toolbarButtons = [[NSArray alloc]initWithObjects:cancelButton,extraSpace,doneButton, nil];
[self.keyboardToolbar setItems:toolbarButtons];
self.myTextView.inputAccessoryView=self.keyboardToolbar;
}
}
I'm adding a couple of buttons to an already-existing NavigationController. The two buttons are added to a UIView, which is pushed onto the NavigationItem. The buttons stop and reload a UIWebView.
Problem is that there's a slight offset issue that is making it all look pretty ugly. I wish I could set the UIToolbar to transparent or clear background but that doesn't seem to be an option. Can't seem to use negative offsets either. I've got color matching, but if you look closely there's 1px or 2px of highlighting up top that's causing a visual mismatch and then a slight offset at the bottom.
Some relevant code below (based on this, inbound Googlers). What are my options to resolve this?
// create a toolbar for the buttons
UIToolbar* toolbar = [[UIToolbar alloc]
initWithFrame:CGRectMake(0, 0, 100, 45)];
[toolbar setBarStyle: UIBarStyleDefault];
UIColor *colorForBar = [[UIColor alloc] initWithRed:.72 green:0 blue:0 alpha:0];
toolbar.tintColor = colorForBar;
[colorForBar release];
//[toolbar setTranslucent:YES];
// create an array for the buttons
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];
// create a standard reload button
UIBarButtonItem *reloadButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
target:self
action:#selector(reload)];
reloadButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:reloadButton];
[reloadButton release];
// create a spacer between the buttons
UIBarButtonItem *spacer = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil
action:nil];
[buttons addObject:spacer];
[spacer release];
// create a standard delete button with the trash icon
UIBarButtonItem *stopButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemStop
target:self
action:#selector(stopLoading)];
stopButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:stopButton];
[stopButton release];
// put the buttons in the toolbar and release them
[toolbar setItems:buttons animated:NO];
[buttons release];
// place the toolbar into the navigation bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
initWithCustomView:toolbar];
[toolbar release];
Update: Alignment was fixed by suggestion by #Jacob below. Now, how to solve the highlighting mismatch?
I've had this same exact issue before, and after some hacking around, I figured this out:
You need to set the height of the UIToolbar's frame to 44.01 for this to work.
EDIT: Re: highlighting mismatch -> You can try setting the backgroundColor to the colorForBar.
UIToolbar* toolbar = [[UIToolbar alloc]
initWithFrame:CGRectMake(0, 0, 100, 44.01)];
UIColor *colorForBar = [[UIColor alloc] initWithRed:.72 green:0 blue:0 alpha:0];
toolbar.tintColor = colorForBar;
toolbar.backgroundColor = colorForBar;
Instead of putting the buttons into a toolbar, you might just make them children views of a parent UIView. You can position a button directly through its frame or center property, without use of spacers, etc.
