Setting Toolbar Items - iphone

I try to set toolbar items in the navigationcontrollers top view. Seems to work in the subviews... but why not in the top view...any ideas? I get the add button... but not my custom button.
- (void)configureToolbarItems {
UIBarButtonItem *addButtonItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
target:self action:#selector(addNewTaskButtonPressed)];
//Green button
greenButton=[app makeGreenButton:self];
UIBarButtonItem *greenBarButton = [[UIBarButtonItem alloc] initWithCustomView:greenButton];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
// Set our toolbar items
[self setToolbarItems:[NSArray arrayWithObjects:
addButtonItem,flexibleSpace, greenBarButton, nil] animated:YES]; }
This is the makeButton procedure... works fine in other views:
-(UIButton*)makeGreenButton:(UIViewController*)caller {
UIButton *greenButton;
//load the image for yellow button
UIImage *greenButtonImage = [UIImage imageNamed:#"greenButton.png"];
//create the button and assign the image
greenButton = [UIButton buttonWithType:UIButtonTypeCustom];
[greenButton setImage:greenButtonImage forState:UIControlStateNormal];
greenButton.showsTouchWhenHighlighted=TRUE;
//set the frame of the button to the size of the image (see note below)
greenButton.frame = CGRectMake(0, 0, greenButtonImage.size.width*2, greenButtonImage.size.height*2);
//Add target
[greenButton addTarget:caller action:#selector(greenButtonReleased:) forControlEvents:UIControlEventTouchUpInside];
return greenButton; }

Change title of backbutton

I need to change the default title value of the back button in a navigationcontroller to something else.
I am trying this with the following code:
UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle: #"Terug" style: UIBarButtonItemStyleBordered target:nil action:nil];
self.navigationItem.backBarButtonItem = newBackButton;
[newBackButton release];
i also tried:
UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle: #"Terug" style: UIBarButtonItemStylePlain target:nil action:nil];
self.navigationItem.backBarButtonItem = newBackButton;
[newBackButton release];
I am using this code at the end of the viewDidLoad.
I am able to create a normal button (square) with the following code:
UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle: #"Terug" style: UIBarButtonItemStyleBordered target:nil action:nil];
self.navigationItem.leftBarButtonItem = newBackButton;
[newBackButton release];
The problem with this solution is that I need to create a seperate method that pop's the view controller. Another issue would be the shape of the button, I need an arrow shaped button.
do you have any idea?
If you want to have a custom back button you need to create new one and assign a new selector to it.
The backBarButtonItem is not editable, so you need to set the leftBarButtonItem.
This is how you can create a custom back button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setTitle:NSLocalizedString(#"Back", nil) forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:#"back.png"] forState:UIControlStateNormal];
[button addTarget:navigationController action:#selector(backAction:)forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:button];
navigationController.navigationItem.leftBarButtonItem = backButton;
[backButton release];
And this is the selector to simulate the back button
- (IBAction)backAction:(id)sender
{
[self.navigationController popViewControllerAnimated:YES];
}
There is a simple solution
lets say you are moving from viewA to viewB
just before moving from viewA to viewB change the title of viewA
for example:
-(void)moveToViewB
{
// Add this line
self.title = #"Terug";
// and push the new view as normal
[self.navigationController pushViewController:viewB animated:NO];
}
Call this button from your 'viewDidLoad' method.
- (void)addCustomBackButton {
/* enter your image name and size here */
UIImage *backImage = [UIImage imageNamed:#"back_btn.png"];
CGRect buttonRect = CGRectMake(5.0f, 0.0f, 12.0f, 20.0f);
/* enter your image name and size here */
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton addTarget:self action:#selector(backAction) forControlEvents:UIControlEventTouchUpInside]; // implemeent 'backAction' method in each VC
[backButton setFrame:buttonRect];
UIImageView *imageView = [[UIImageView alloc] initWithImage:backImage];
[imageView setFrame:buttonRect];
[backButton addSubview:imageView];
UIBarButtonItem *homeButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = homeButtonItem;
}
[Or, make it a class method of a 'Utitlity' class and call it as a class method in each viewContorller it is required.]
Also, don't forget to implement the 'backAction', something like this:
- (void)backAction
{
[self.navigationController popViewControllerAnimated:YES];
}
Happy coding!

why images not coming for UIBarButton item of navigation Bar

Here is my code. This is adding image but images are being appeared in navigation bar.
UIToolbar* toolbartop = [[UIToolbar alloc]
initWithFrame:CGRectMake(0, 0, 100, 45)];
[toolbar setBarStyle: UIBarStyleBlackOpaque];
// create an array for the buttons
NSMutableArray* buttonstop = [[NSMutableArray alloc] initWithCapacity:5];
UIBarButtonItem *remainderButton = [[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:#"home.png"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(LoadOption:)];
[buttonstop addObject:remainderButton];
[remainderButton release];
UIBarButtonItem *faveButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"home.png"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(homeAction)];
[buttonstop addObject:faveButton];
[faveButton release];
// put the buttons in the toolbar and release them
[toolbartop setItems:buttonstop animated:NO];
[buttonstop release];
// place the toolbar into the navigation bar
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbartop];
But this code is showing image in navigation right bar.
UIBarButtonItem *settingButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"home.png"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(homeAction)];
self.navigationItem.rightBarButtonItem = settingButton;
Why left navigation bar button is not showing images?
[toolbartop release];
You can add the image to your left BarButtonItem as follows:
UIButton *button1 = [[UIButton alloc] init];
button1.frame=CGRectMake(0,0,105,30);
[button1 setBackgroundImage:[UIImage imageNamed: #"image1.png"] forState:UIControlStateNormal];
[button1 addTarget:appDelegate action:#selector(Open_Link1) forControlEvents:UIControlEventTouchUpInside];
UIButton *button2 = [[UIButton alloc] init];
button2.frame=CGRectMake(105,0,105,30);
[button2 setBackgroundImage:[UIImage imageNamed: #"image2.png"] forState:UIControlStateNormal];
[button2 addTarget:appDelegate action:#selector(Open_Link2) forControlEvents:UIControlEventTouchUpInside];
UIView *viewButtons = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 210, 30)];
[viewButtons addSubview:button1];
[viewButtons addSubview:button2];
[button1 release];
[button2 release];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:viewButtons];
[viewButtons release];
Here please make sure that the methods "Open_Link1" and "Open_Link2" must exists in the code as follows:
-(void)Open_Link1
{
// Write your logic
}
-(void)Open_Link2
{
// Write your logic
}
Let me know if you want more help.
The left bar button item is automatically used by the framework for showing a "Back" button. You can't put anything here, at least not when your navigation bar is managed by a UINavigationController. For this to work you have to handle the UINavigationBar yourself.
Edit:
in your leftBarButtonItem, try putting a UISegmentedControl instead of a UIToolbar for toolbartop.
You are adding a button to toolbar but you aren't adding your toolbar to any view. Try to set the button directly using
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:buttonStop];

Multiple UIBarButtonItems in UINavigationBar

How to Create multiple bar button in navigation bar?
From iOS 5 onwards, you can now do it using setLeftBarButtonItems:animated: or setRightBarButtonItems:animated:
You must use UIToolbar and set the toolbar with buttons:
// create a toolbar where we can place some buttons
UIToolbar *toolbar = [[UIToolbar alloc]
initWithFrame:CGRectMake(0, 0, 100, 45)];
[toolbar setBarStyle: UIBarStyleBlackOpaque];
// create an array for the buttons
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3];
// create a standard save button
UIBarButtonItem *saveButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemSave
target:self
action:#selector(saveAction:)];
saveButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:saveButton];
// create a spacer between the buttons
UIBarButtonItem *spacer = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil
action:nil];
[buttons addObject:spacer];
// create a standard delete button with the trash icon
UIBarButtonItem *deleteButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemTrash
target:self
action:#selector(deleteAction:)];
deleteButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:deleteButton];
// put the buttons in the toolbar and release them
[toolbar setItems:buttons animated:NO];
// place the toolbar into the navigation bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
initWithCustomView:toolbar];
you have to create a view with as much button you required and have to add them on navigation button like following :
UIView *parentView1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 60, 44)];
UIButton *infoButton1 = [[UIButton alloc] initWithFrame:CGRectMake(0, 6, 30, 32)];
[infoButton1 setBackgroundImage:[UIImage imageNamed: #"navbtn.png"] forState:UIControlStateNormal];
[infoButton1 setTitle:#"Back" forState:UIControlStateNormal];
infoButton1.titleLabel.font = [UIFont systemFontOfSize:13.0f];
infoButton1.titleLabel.textColor = [UIColor whiteColor];
[infoButton1 addTarget:self action:#selector(backBarButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[parentView1 addSubview:infoButton1];
[infoButton1 release];
UIButton *infoButton2 = [[UIButton alloc] initWithFrame:CGRectMake(30, 6, 30, 32)];
[infoButton2 setBackgroundImage:[UIImage imageNamed: #"navbtn.png"] forState:UIControlStateNormal];
[infoButton2 setTitle:#"Back" forState:UIControlStateNormal];
infoButton2.titleLabel.font = [UIFont systemFontOfSize:13.0f];
infoButton2.titleLabel.textColor = [UIColor whiteColor];
[infoButton2 addTarget:self action:#selector(backBarButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[parentView1 addSubview:infoButton2];
[infoButton2 release];
UIBarButtonItem *customBarButtomItem1 = [[UIBarButtonItem alloc] initWithCustomView:parentView1];
[parentView1 release];
self.navigationItem.leftBarButtonItem = customBarButtomItem1;
[customBarButtomItem1 release];`enter code here`
I know this question was already closed, but I find that the UIToolbar solution doesn't match visually.
If you instead use a second UINavigationBar set with a UINavigationItem that has a title of nil and the desired buttons you can add more buttons and have a bar that visually matches the original.
For iOS7 and higher, this is the right way to do it. No need for UIToolbar silliness.
- (void)viewDidLoad {
[super viewDidLoad];
[self configureView];
// create three funky nav bar buttons
UIBarButtonItem *one = [[UIBarButtonItem alloc]initWithTitle:#"One" style:UIBarButtonItemStylePlain target:self action:#selector(testMethod)];
UIBarButtonItem *two = [[UIBarButtonItem alloc]initWithTitle:#"Two" style:UIBarButtonItemStylePlain target:self action:#selector(testMethod)];
UIBarButtonItem *three = [[UIBarButtonItem alloc]initWithTitle:#"Three" style:UIBarButtonItemStylePlain target:self action:#selector(testMethod)];
// create a spacer
UIBarButtonItem *space = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil];
space.width = 30;
NSArray *buttons = #[one, space, two, space, three];
self.navigationItem.rightBarButtonItems = buttons;
}
I hate putting links as answers on SO as they can die anytime so i added relevant code taken from HERE
- (void)viewWillAppear
{
// get a view and :
[self.navigationController.navigationBar addSubView:yourView];
}

UIButton animation view

I am new developer in iPhone.
I want to create uibutton.
When I click the button, then the button will be flash like as below.
How to create the flash, when I click my button?
There is a property of UIButton named showsTouchWhenHighlighted. If you set the property to YES, it will show the glow when you touch the button. It's default value is NO.
[yourButton setShowsTouchWhenHighlighted:YES];
What you do is set the highlighted image. For example:
[someButton setImage:[UIImage imageNamed:#"MyHighlight.png"]
forState:UIControlStateHighlighted];
Then when a user taps it, your MyHighlight.png will show.
toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleDefault;
[toolbar sizeToFit];
toolbar.frame = CGRectMake(0, 410, 320, 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
[toolbar setItems:items animated:NO];
[self.view addSubview:toolbar];
use this to create toolBar.
and use this for search button
UIBarButtonSystemItemSearch
If you want to change the button image when you clicked on button now set different images for both default and highlighted stats. As:
[tempButton setImage:[UIImage imageNamed:#"NormalImage.png"]
forState:UIControlStateNormal];
[tempButton setImage:[UIImage imageNamed:#"HighlightImage.png"]
forState:UIControlStateHighlighted];
If you want the flash effect for the same image, when button is clicked on,
In your XIB, Goto Inspector window > control > check the Highlighted property.
You can try this by code as:
[tempButton setShowsTouchWhenHighlighted:YES];
//or
tempButton.highlighted = YES;

iphone UIBarButtonItem initWithImage - doesn't highlight when tapped

I can create a button like this, and the action works fine:
UIBarButtonItem *myBtn = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"image.png"] style:UIBarButtonItemStyleBordered target:self action:#selector(myMethod:)];
However, when tapping the button on screen, no Down state highlight is displayed. I've tried everything. Can you not get a highlight on a UIBarButtonItem with a custom image?
Try something like this (setShowsTouchWhenHighlighted: is what you're looking for):
UIImage* image = [UIImage imageNamed:#"image.png"];
CGRect frame = CGRectMake(0, 0, image.size.width, image.size.height);
UIButton* button = [[UIButton alloc] initWithFrame:frame];
[button setBackgroundImage:image forState:UIControlStateNormal];
[button addTarget:self action:#selector(myMethod:) forControlEvents:UIControlEventTouchUpInside];
[button setShowsTouchWhenHighlighted:YES];
UIBarButtonItem* barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
[self.navigationItem setRightBarButtonItem:barButtonItem];
[barButtonItem release];
[button release];
Maybe something a little bit easier for most beginners:
Code for Button Creation
UIBarButtonItem *editButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Edit" style:UIBarButtonItemStyleBordered target:self action:#selector(editCells:)];
self.navigationItem.rightBarButtonItem = editButtonItem;
[editButtonItem release];
Code for Action Handler
- (void)editCells:(id)sender {
UIBarButtonItem *buttonItem = (UIBarButtonItem *)sender;
if (self.tableView.editing == YES) {
self.tableView.editing = NO;
buttonItem.title = #"Edit";
buttonItem.style = UIBarButtonItemStyleBordered;
}
else {
self.tableView.editing = YES;
buttonItem.title = #"Done";
buttonItem.style = UIBarButtonItemStyleDone;
}
}
Explanation
Pretty straight forward. I create the button programatically and add it to the views navigation bar. Of course, this only works when using a NavigationController.
When the user clicks the button to start editing the related table view, the function checks the table editing state and changes the text of the button as well as the style.
