I create a custom right view as follows:
// Build the Segmented Control
NSArray *segmentTextContent = [NSArray arrayWithObjects:[UIImage imageNamed:#"arrow-dice.png"], [UIImage imageNamed:#"arrow-up.png"], [UIImage imageNamed:#"arrow-down.png"], nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentTextContent];
// Customize the Segmented Control
segmentedControl.momentary = YES;
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
[segmentedControl addTarget:self action:#selector(segmentChanged:) forControlEvents:UIControlEventValueChanged];
Then I add it to my navigation bar as follows:
// Add the control to the navigation bar right item
UIBarButtonItem *segmentItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[segmentedControl release];
self.navigationItem.rightBarButtonItem = segmentItem;
self.navigationItem.rightBarButtonItem.title = #"";
[segmentItem release];
I can hide it as follows:
self.navigationItem.rightBarButtonItem.customView.hidden = NO;
QUESTION
...but how can I disable all (or better, a specific element) of the segmented control?
The following does not work.
self.navigationItem.rightBarButtonItem.enabled = NO;
Any ideas appreciated...
Thanks,
matt
UISegmentedControl.h
- (void)removeSegmentAtIndex:(NSUInteger)segment animated:(BOOL)animated;
- (void)removeAllSegments;
- (void)setEnabled:(BOOL)enabled forSegmentAtIndex:(NSUInteger)segment; //default is YES
e.g. [segmentedControl setEnabled:NO forSegmentAtIndex:1];
Hope That helps
[navItem.rightBarButtonItem setEnabled:NO];
as simple as that :)

I want to make a NavBar similar to the one in sample 3 of the NavBar sample code, except I want to use the self.editbuttonItem as one of the two buttons in the SegmentedControl. (The other will be a custom add button.) Basically - the end result will be a leftBarButtonItem that's just one button, bringing up a modal view, and a rightBarButtonItem that's a segmented control with both edit and add buttons.
Thing is, it looks like setting up the SegmentedControl needs an array of Strings or Images, but not BarButtonItems. Is there a workaround?
This is the relevant bit from Apple's sample:
// "Segmented" control to the right
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:
[UIImage imageNamed:#"up.png"],
[UIImage imageNamed:#"down.png"],
nil]];
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.frame = CGRectMake(0, 0, 90, kCustomButtonHeight);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.momentary = YES;
defaultTintColor = [segmentedControl.tintColor retain]; // keep track of this for later
UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[segmentedControl release];
self.navigationItem.rightBarButtonItem = segmentBarItem;
[segmentBarItem release];
Instead of the images, I want to put BarButtonItems...
If self.editbuttonitem is a UIBarButtonItem with title "Edit", I think you can do with the following code
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:
#"Edit", #"AnotherButtonName"
nil]];
edit based on Charles Bandes's comment
Add an action to the segmentedControl, like the Apple's sample:
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
//...
then in segmentAction:, do
- (void)segmentAction:(UISegmentedControl*)sender
{
//if the "edit" item in segmentedControl is selected
if (sender.selectedSegmentIndex == 0)
{
//I assume self is a UITableView instance
//start editing
[self setEditing:YES animated:YES];
}
}
I wrote those code on my PC. However it should work.
You may take a look at [UITableView setEditing:animated:]
I can not understand why navigation bar is not going to add any button other than cancel button in Following code
this kind of thing done in Viber application so it is possible
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.navigationBar.tintColor=[UIColor colorWithRed:91.0/256.0 green:72.0/256.0 blue:110.0/256.0 alpha:1.0];
//picker.navigationController.navigationBar.topItem.rightBarButtonItem = nil;
[picker.navigationBar setHidden:NO];
picker.peoplePickerDelegate = self;
// Display only a person's phone, email, and birthdate
NSArray *displayedItems = [NSArray arrayWithObjects:[NSNumber numberWithInt:kABPersonPhoneProperty],
[NSNumber numberWithInt:kABPersonEmailProperty],
[NSNumber numberWithInt:kABPersonBirthdayProperty], nil];
//picker.navigationBarHidden=TRUE;
picker.displayedProperties = displayedItems;
//UIBarButtonItem *addbutton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(AddContact)];
// picker.navigationController.navigationBar.topItem.rightBarButtonItem = addbutton;
[self presentModalViewController:picker animated:NO];
[picker release];
//[addbutton release];
can anybody help please
refer this article it demonstrates how to add custom button on ABPeoplePickerNavigationController
i can show you how to add custom button to navigation bar. Use this code if this is helpful,
UIImage *buttonImage = [UIImage imageNamed:#"Done.png"];
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[aButton setImage:buttonImage forState:UIControlStateNormal];
aButton.frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height);
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButtonaddTarget:selfaction:#selector(navigatehome)forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.rightBarButtonItem = aBarButtonItem;
[aBarButtonItem release];
Come oon!
I am almost looking a day at this!
I want to set my tint color of my UISegmentedControl but it doesnt react...
NSArray *segControlItems = [NSArray arrayWithObjects:
#"L",
#"H",
#"A",
nil];
UISegmentedControl *segControl = [[UISegmentedControl alloc] initWithItems:segControlItems];
segControl.frame = CGRectMake(0, 0, 90, 30);
segControl.segmentedControlStyle = UISegmentedControlStyleBar;
segControl.momentary = YES;
segControl.tintColor = [UIColor greenColor];
[segControl addTarget:self action:#selector(segAction:) forControlEvents:UIControlEventValueChanged];
UIBarButtonItem *segBarItem = [[UIBarButtonItem alloc] initWithCustomView:segControl];
self.switchView.navigationItem.rightBarButtonItem = segBarItem;
[segControl release];
[segBarItem release];
Has apple made some property like "makeUISegmentedControlsDontSetAnyTintColor" ore soo?
Please help...
A single button works: http://img257.imageshack.us/i/schermafbeelding2010102.png/
But with the segmented it's messed up: http://img714.imageshack.us/i/schermafbeelding2010102.png/
I've done it without problems using InterfaceBuilder. I had three segments, some with labels, some with labels + pictures, all working fine.
It must be your conversion into a BarButtonItem that doesn't work. You could try adding the segmented control as a subview of the nav bar instead of coaxing it into a button.
This is a really old question but I ran into this problem today (Xcode 7b5/iOS 9). In my case the segmentedControl was a UIBarButtonItem in the navBar. I was able to set the tintColor by waiting for the next run loop, like so:
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] init]
(...additional setup...)
UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
self.navigationItem.rightBarButtonItem = segmentBarItem;
dispatch_async(dispatch_get_main_queue(), ^{
segmentedControl.tintColor=[UIColor purpleColor];
});
I want two rightBarButtonItem's on my UINavigationBar. How can I accomplish this?
You can use a UISegmentedControl with two buttons and configure it with the momentary property set to YES.
This is what is used in the Mail application to go to next/previous message.
Update
In order to assign the UISegmentedControl]1 as a right button, you have to wrap it inside a UIBarButtonItem (sample code taken from the NavBar sample application):
- (void)viewDidLoad
{
// "Segmented" control to the right
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:
[UIImage imageNamed:#"up.png"],
[UIImage imageNamed:#"down.png"],
nil]];
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.frame = CGRectMake(0, 0, 90, kCustomButtonHeight);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.momentary = YES;
UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[segmentedControl release];
self.navigationItem.rightBarButtonItem = segmentBarItem;
[segmentBarItem release];
}
Is it possible to add buttons to the navigation bar using the IPhone SDK?
I already have 2 buttons in the navigation bar as leftBarButton and rightBarButton. I need 2 more buttons. How to implement that?
Its not obligatory that i need them to be included in the navigation bar itself. But since the application contains only a table, i don't think it can be given elsewhere.
You can use the UISegmentedControl. Check the UICatalog code sample to check its usage in the navigation bar.
Here is some sample code:
- (void)viewDidLoad {
[super viewDidLoad];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:
[UIImage imageNamed:#"up.png"],
[UIImage imageNamed:#"down.png"],
nil]];
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.frame = CGRectMake(0, 0, 90, 35);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.momentary = YES;
UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[segmentedControl release];
self.navigationItem.rightBarButtonItem = segmentBarItem;
[segmentBarItem release];
}
- (void)segmentAction:(id)sender{
if([sender selectedSegmentIndex] == 0){
//do something with segment 1
NSLog(#"Segment 1 preesed");
}else{
//do something with segment 2
NSLog(#"Segment 2 preesed");
}
}
