I use code similar to following code make a custom toolbar. But it disabling functionality not working,
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithTitle:nil style:UIBarButtonItemStyleBordered target:self action:#selector(navigationCart:)];
barButtonItem.image = [self imageCartIconNormal];
barButtonItem.enabled = NO;
[self setToolbarItems:[[NSMutableArray arrayWithObjects:barButtonItem,barButtonItem1, barButtonItem2, nil] animated:YES];
Thank you in advance.
Tested and working :
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:nil
style:UIBarButtonItemStyleBordered target:self action:nil];
button.enabled = NO;
button.image = [UIImage imageNamed:#"icon"];
[self.toolbar setItems:#[button] animated:YES];
Make sure your imageCartIconNormal returns a UIImage.
Make sure your setToolbarItems calls the method above on an UIToolbar.
NB: There is no use in a mutable array here.

I'm trying to add button to navigation bar i want to add the button without any action any help please?
UIBarButtonItem *yourButton = [[UIBarButtonItem alloc]
initWithTitle:#"Your Button"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(methodName:)];
self.navigationItem.rightBarButtonItem = yourButton;
[yourButton release];
And then method
-(IBAction)methodName {
// your code here
}
You should add UIBarButtonItem to Nav bar instead of UIButton. T do that you can call this:
UIBarButtonItem *button = [[UIBarButtonItem alloc]
initWithTitle:#"Title"
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
self.navigationItem.rightBarButtonItem = button;
UIBarButtonItem *customBtn=[[UIBarButtonItem alloc] initWithTitle:#"Custom" style:UIBarButtonItemStylePlain target:self action:#selector(customBtnPressed)];
[self.navigationItem setRightBarButtonItem:customBtn];
///// called event
-(IBAction)customBtnPressed:(id)sender
{
//Your code here
}
if UIButton is you really want, try this.
UIButton *btnSample = [[UIButton alloc] initWithFrame:btnFrame];
btnSample.backgroundColor = [UIColor blueColor];
UIBarButtonItem *barBtn_cart = [[UIBarButtonItem alloc] initWithCustomView:btnSample];
self.navigationItem.rightBarButtonItem = btnSample;
In UITableView I configure self.navigationItem.leftBarButtonItem with a button. Now I want to reload this button to update text on this button, but it's on Navigation bar. I can update UITableView by
[self.tableView reloadData]
but How to update Navigation bar?
Update: I'm NOT init the title of button, but reload it. So any init code (such as self.navigationItem.leftBarButtonItem.title = #"balabala") doesn't work, because it does NOT take effect immediately.
Just change the text on the leftBarButtonItem?
self.navigationItem.leftBarButtonItem.title = #"Back"; // or whatever text you want
Try this
UIBarButtonItem *btnBack = [[UIBarButtonItem alloc]
initWithTitle:#"Title"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(OnClick:)];
self.navigationItem.leftBarButtonItem = btnBack;
Hope this helps you..
EDIT :-
UIBarButtonItem *btnBack = [[UIBarButtonItem alloc] initWithTitle: #"Title" style: UIBarButtonItemStyleBordered target:self action:#selector(OnClick:)];
[[self navigationItem] setBackBarButtonItem: btnBack];
Did you try setting the text, using
self.navigationItem.leftBarButtonItem.title
You need to use the following statement:
self.navigationItem setLeftBarButtonItem:cancelButton animated:YES];
In other words you need the setLeftBarButtonItem:animated message instead of the standard one. This will reload the button text with animation. Same applies for the back button if that is what you are interested in changing at some point.
#interface Myviewcontroller : UIViewController
{
UIBarButtonItem *barBtnBack;
UIButton *btnQuestion;
}
//ViewdidLoad
btnQuestion = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 20, 25)];
[btnQuestion setBackgroundImage:[UIImage imageNamed:#"question-mark2x"] forState:UIControlStateNormal];
[btnQuestion addTarget:self action:#selector(goBacktomain)
forControlEvents:UIControlEventTouchUpInside];
barBtnBack =[[UIBarButtonItem alloc] initWithCustomView:btnQuestion];
[self.navigationItem setLeftBarButtonItem:barBtnBack];
note- change btnQuestion title when you want to change navigationnar button title
If you want to change the NavigationBar title, try 1 of these:
[self.navigationController.navigationItem setTitle:#"Title"];
[self.navigationItem setTitle:#"Title"];
[self setTitle:#"Title"];
If you wanna change button titles, put this in the same class:
- (void)setLeftBarButtonTitle:(NSString *)title action:(SEL)selector
{
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithTitle:title style:UIBarButtonItemStyleBordered target:self action:selector];
[self.navigationItem setLeftBarButtonItem:leftButton];
}
- (void)setRightBarButtonTitle:(NSString *)title action:(SEL)selector
{
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:title style:UIBarButtonItemStyleBordered target:self action:selector];
[self.navigationItem setRightBarButtonItem:rightButton];
}
Examples to set button title and actions:
// Change button titles and actions any time
[self setLeftBarButtonTitle:#"Back" action:#selector(goBack)];
[self setRightBarButtonTitle:#"Something" action:#selector(doSomething:)];
// Change button titles with no actions
[self setLeftBarButtonTitle:#"Nothing" action:nil];
[self setRightBarButtonTitle:#"Nothing" action:nil];
// Remove buttons from navigation bar
[self.navigationItem setLeftBarButtonItem:nil];
[self.navigationItem setRightBarButtonItem:nil];
Try this:
UIBarButtonItem *backButton = [[UIBarButtonItem alloc]
initWithTitle:#"your_title"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(backBtnPressed:)];
self.navigationItem.leftBarButtonItem = backButton;
I solved it in Swift, but if the keyboard is shown, it hides.
navigationController?.loadView()
I have 2 bar buttons on the tool bar , one is not working and the other is working. Some times when we touch the tip of the first bar button it will work, I think this has to be a problem with flexible space between them.
I couldn't find any possible solution, any help will be appreciated!
I'm pasting the code below
editbutton is the first button and mybutton is the second button
-(void) rightButtonToolbar:(UIBarButtonItem*)menuButton{
UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,TOOLBAR_WIDTH ,44)];
NSMutableArray *barButtons = [[NSMutableArray alloc]init];
UIBarButtonItem *flexiSpace = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barButtons addObject:flexiSpace];
if (showEditButton)
{
NSLog(#"showeditbutton");
UIBarButtonItem *editButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:#selector(editOffer)];
[barButtons addObject:editButton];
[editButton release];
}
UIBarButtonItem *myButton2 = [[UIBarButtonItem alloc] initWithTitle:#"Kopiren" style:UIBarButtonSystemItemAction target:self action:#selector(copyOffer)];
[barButtons addObject:myButton2];
if (menuButton != nil) {
menuButtonShown=YES;
[barButtons addObject:menuButton];
}
else {
menuButtonShown=NO;
}
[toolbar setItems:barButtons animated:YES];
UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc]initWithCustomView:toolbar];
[self.navigationItem setRightBarButtonItem:rightBarButton animated:YES];
[barButtons release];
[flexiSpace release];
[rightBarButton release];
[toolbar release];
[myButton2 release];
}
in my app i have a uinavigationbar with 3 buttons, but the code i used for ios5 does not seem to be good for ios6 anymore.
You can see a wrong-colored rect underneath my custum-view with two buttons on the right side.
heres the code i used, i found it somewhere on stackoverflow:
UIToolbar *tools = [[[UIToolbar alloc]
initWithFrame:CGRectMake(0.0f, 0.0f, 110.0f, 44.01f)] autorelease]; // 44.01 shifts it up 1px for some reason
tools.clearsContextBeforeDrawing = NO;
tools.clipsToBounds = NO;
tools.translucent = self.headerbar.translucent;
tools.barStyle = self.headerbar.barStyle;
tools.backgroundColor = self.headerbar.backgroundColor;
tools.tintColor = self.headerbar.tintColor;
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3];
// Create a standard refresh button.
UIBarButtonItem *bi = [[UIBarButtonItem alloc] initWithTitle:#"heute" style:UIBarButtonItemStylePlain target:self action:#selector(showThisWeek)];
bi.style = UIBarButtonItemStyleBordered;
bi.width = 0;
[buttons addObject:bi];
//[bi release];
// Create a spacer.
bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:#selector(showThisWeek)];
[buttons addObject:bi];
//[bi release];
// Add profile button.
bi = [[UIBarButtonItem alloc] initWithTitle:#"vor" style:UIBarButtonItemStylePlain target:self action:#selector(showNext)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
//[bi release];
// Add buttons to toolbar and toolbar to nav bar.
[tools setItems:buttons animated:NO];
[buttons release];
UIBarButtonItem *twoButtons = [[UIBarButtonItem alloc] initWithCustomView:tools];
//[tools release];
header.rightBarButtonItem = twoButtons;
[header.leftBarButtonItem setAction:#selector(showPrevious)];
can someone hint me to a more elegant solution that works fine on both ios5 and ios6?
cheers

Did you try leftBarButtonItems and rightBarButtonItems? You can add array of buttons in left and right side nav bar using this.
If you use this, there will be no need for UIToolbar and their subviews.
Have you tried bar.style = -1?
Accept my early apologies as totally new to this so my terminology may not be accurate, hope you can understand what it is that i'm asking.
I am having issues getting a UIBarButtonSystemItem to take me back to a different view when pushed. I have defined a UIToolBar with a UIBarButtonSystemItem on it which compiles and works perfectly. However, when the button is pushed the app crashes.
This is the code i have used to define the UIToolBar and UIButton:
//create toolbar using new
toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleBlackTranslucent;
[toolbar sizeToFit];
toolbar.frame = CGRectMake(0, 410, 320, 50);
//Add buttons
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAction
target:self
action:#selector(pressButton1:)];
I have then added flexitem to this and added the button to the array using the following code:
//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, nil];
This is where I fall down and I have attempted to get the button to take me to a previous view when pushed by using the following code:
-(void)pressButton1:(id)sender {
BMR_TDEE_CalculatorViewController *controller1 = [[BMR_TDEE_CalculatorViewController alloc] initWithNibName:#"BMR_TDEE_ViewController" bundle:nil];
controller1.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller1 animated:YES];
[controller1 release];
}
Like I said, this just crashes my simulator. It compiles without issue but Im guessing the code is fundamentally wrong as i am new to this. Any help explained dumbed down would be fantastic ;-)
Thanks All
This:
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:#selector(pressButton1:)
should be:
UIButton *button=[[UIButton alloc] init];
button.frame=CGRectMake(0, 0, 65, 32);
[button addTarget:self action:#selector(pressButton1:) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
For the (void)pressbutton code it should now be:
-(IBAction)pressButton1:(id)sender {
BMR_TDEE_CalculatorViewController *controller = [[BMR_TDEE_CalculatorViewController alloc] initWithNibName:#"BMR_TDEE_CalculatorViewController" bundle:nil];
[self.navigationController presentModalViewController:controller animated:TRUE];
}
