I did when I click when textField ,Open UIPickerView and then select PickerView Data it's display on UITextField.
But now i Have 3 text_Filed(city,typeofcars,branches) but I don't know about three TextFileds on Single UIPickerView. So Please give me any idea .
single text-Filed one UIPickerview code is:-
Businessname=[[UITextField alloc]init];
Businessname.frame=CGRectMake(0, 0, 221, 33);
Businessname.placeholder=#"Business Name";
[Businessname setFont:[UIFont fontWithName:#"Times New Roman" size:13]];
Businessname.backgroundColor=[UIColor whiteColor];
[Businessname setBorderStyle:UITextBorderStyleBezel];
Businessname.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
Businessname.layer.borderColor=[[UIColor yellowColor]CGColor];
Businessname.layer.borderWidth= 2.0f;
Businessname.textColor=[UIColor blackColor];
[scrol addSubview:Businessname];
yourpicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 400, 100, 150)];
[yourpicker setDataSource: self];
[yourpicker setDelegate: self];
yourpicker.showsSelectionIndicator = YES;
Businessname.inputView = yourpicker;
[yourpicker setShowsSelectionIndicator:YES];
mypickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 300, 100, 56)];
mypickerToolbar.barStyle = UIBarStyleBlackOpaque;
[mypickerToolbar sizeToFit];
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(pickerDoneClicked)];
[barItems addObject:doneBtn];
[mypickerToolbar setItems:barItems animated:YES];
Businessname.inputAccessoryView = mypickerToolbar;
-(void)pickerDoneClicked
{
NSLog(#"Done Clicked");
[Businessname resignFirstResponder];
mypickerToolbar.hidden=YES;
yourpicker.hidden=YES;
}
- (NSInteger)numberOfComponentsInPickerView:
(UIPickerView *)pickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component
{
return [pickarray count];
}
Above code is output is when I click text-filed and then open UIPIckerView and then choose the data. But now I have three TextFields and 3 NSArrays on Please how to pass data data to UIPickerView based on UITextField.
So please give me any idea about my problem
Thanks in Advanced
You can do this by setting tag value for each textfield. Also set delegate of UITextField for each textfield.
In delegate method of UITextField
- (void)textFieldDidBeginEditing:(UITextField *)textField
recongnize textfield by it's tag value.
Based on tag value do something like
// Assumed taht 100, 101, 102 is the tag values for textfield's
NSInteger tag = textField.tag;
switch(tag)
{
case 100:
pickarray = #[#"1",#"2",#"3",#"4"];
break;
case 101:
pickarray = #[#"10",#"20",#"30",#"40"];
break;
case 102:
pickarray = #[#"11",#"21",#"31",#"41"];
break;
default:
break;
}
by this you can assign different values to "pickarray" according to selected textfield and reload your UIPickerView.
I am trying to dismiss a UIPickerView using a toolbar similar to the inputAccessoryView on keyboards.
I am using the same UIToolbar for both my text field and my picker, the textfield will dismiss properly, but the picker doesn't even recognize my touch on the button.
This is the code I am using to create the toolbar:
UIToolbar *tipToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
tipToolbar.barStyle = UIBarStyleDefault;
UIBarButtonItem *donebtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(resignResponder:)];
tipToolbar.items = [NSArray arrayWithObjects:
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
donebtn, nil
];
[tipToolbar sizeToFit];
_outlet_txt_ipaddr.inputAccessoryView = tipToolbar;
[_outlet_picker addSubview:tipToolbar];
And this is the action that will dismiss the keyboard or the picker:
- (IBAction)resignResponder:(id)sender{
[_outlet_txt_ipaddr resignFirstResponder];
[_outlet_picker resignFirstResponder];
}
The toolbar appears on the picker view, but my tap on the done button isn't even showing the animation let alone call the resignResonder action.
for picker view [_outlet_picker resignFirstResponder]; will not work.
you need to implement the delegate for picker view.
try this code
UIToolbar *tipToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
tipToolbar.barStyle = UIBarStyleDefault;
UIBarButtonItem *donebtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(resignResponder:)];
tipToolbar.items = [NSArray arrayWithObjects:
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
donebtn, nil
];
[tipToolbar sizeToFit];
_outlet_txt_ipaddr.inputAccessoryView = tipToolbar;
_outlet_picker.delegate=self;
_outlet_picker.dataSource=self;
_outlet_picker.showsSelectionIndicator=YES;
[self.view addSubview:outlet_picker];
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
{
return [pickerValueAry count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component;
{
NSMutableArray *ary = [[NSMutableArray alloc] initWithArray:pickerValueAry];
id str=[ary objectAtIndex:row];
return str;
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
NSLog(#"selectedRowInPicker >> %d",row);
}
you can dismiss the picker view on row select.
I have written the following code in the viewDidLoad method:
categoryPickerView=[[UIPickerView alloc]init];
categoryPickerView.alpha = 0;
[self.view addSubview:categoryPickerView];
categoryPickerView.delegate=self;
categoryPickerView.tag=1;
and called this method to hide picker view
- (IBAction)hidePickerView:(id)sender {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.6];
CGAffineTransform transfrom = CGAffineTransformMakeTranslation(0, 200);
categoryPickerView.transform = transfrom;
categoryPickerView.alpha = categoryPickerView.alpha * (-1) + 1;
[UIView commitAnimations];
}
My problem is that I want to display a "Done" button on a picker view and the picker view should hide on button click.
You can use this code,
UIToolbar *toolBar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,0,320,44)];
[toolBar setBarStyle:UIBarStyleBlackOpaque];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered target:self action:#selector(changeDateFromLabel:)];
toolBar.items = #[barButtonDone];
barButtonDone.tintColor=[UIColor blackColor];
[pickerView addSubview:toolBar];
//(or)pickerView.inputAccessoryView = toolBar;
and set button action method for changeDateFromLabel:
-(void)changeDateFromLabel:(id)sender
{
[[your UI Element] resignFirstResponder];
}
You can create view and add toolbar with "Done" button and UIPickerView as subviews
- (void)createInputView {
CGFloat screenWidth = [UIScreen mainScreen].bounds.size.width;
UIToolbar *toolBar= [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, screenWidth, 44)];
[toolBar setBarStyle:UIBarStyleDefault];
UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(doneClicked)];
toolBar.items = #[flex, barButtonDone];
barButtonDone.tintColor = [UIColor blackColor];
UIPickerView *picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, toolBar.frame.size.height, screenWidth, 200)];
picker.delegate = self;
picker.dataSource = self;
picker.showsSelectionIndicator = YES;
UIView *inputView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, screenWidth, toolBar.frame.size.height + picker.frame.size.height)];
inputView.backgroundColor = [UIColor clearColor];
[inputView addSubview:picker];
[inputView addSubview:toolBar];
textField.inputView = inputView;
}
- (void)doneClicked {
[textField resignFirstResponder];
}
You need to use the UIToolbar as the accessory view:
Try with this:
#pragma mark - PickerView for Location Selection
- (UIPickerView *)locationsPicker {
if ( locationsPicker == nil ) {
locationsPicker = [[UIPickerView alloc] init];
locationsPicker.delegate = self;
locationsPicker.dataSource = self;
locationsPicker.showsSelectionIndicator = YES;
}
return locationsPicker;
}
- (UIToolbar *)accessoryView {
if ( accessoryView == nil ) {
accessoryView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemDone
target:self
action:#selector(onLocationSelection)];
[accessoryView setItems:[NSArray arrayWithObject:doneButton]];
}
return accessoryView;
}
- (void)onLocationSelection {
NSInteger row = [self.locationsPicker selectedRowInComponent:0];
if ( [Location isFirstResponder] ) {
NSLog(#"%#", [listOfLocations objectAtIndex:row]);
[Location resignFirstResponder];
}
}
Copy-pasteable solution!
This works in iOS 10 (and probably other versions too) I wrote this code on 9/4/2017.
I needed to combine other answers to get what I wanted, which was a Cancel button, Done button, and a picker view that would show/hide on the tap of a button. Ignore the fact that my screenshot only has one item in the picker.. I only have one item in my array. I've tested multiple items, it works fine.
Disclaimer! I have tested and used this code. I generalized the names in my example, so I apologize in advance if I missed one and they property names don't line up.
In order to have a pickerView that appears on the tap of a button, you need to create a dummyTextField (of type UITextField anywhere in your view controller. This is because UIPickerView's are designed to work with UITextFields. To mimic showing and hiding of the picker, your button taps need to call the dummyTextField's becomeFirstResponder and resignFirstResponder methods. (examples are below)
Step one
Create a custom data source class. MyObj is the class you want to have items show up in the picker for.
In .h:
#import <UIKit/UIKit.h>
#class myObj;
#interface PickerDataSource : NSObject <UIPickerViewDataSource, UIPickerViewDelegate>
#property (nonatomic, strong) MyObj *selectedObject;
#end
In .m:
#import "PickerDataSource.h"
#import "MyObj.h"
#implementation PickerDataSource
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
self.selectedObject = mySourceArray[row];
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return mySourceArray.count;
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 1;
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
return ((MyObj *)mySourceArray[row]).myTitle;
}
- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component {
int sectionWidth = 300;
return sectionWidth;
}
#end
Step two In your view controller, import custom data source, delegate, and set properties: (You must include the text field delegate!)
#import "PickerDataSource.h"
#interface MyViewController () <UIPickerViewDelegate, UITextFieldDelegate>
#property (strong, nonatomic) PickerDataSource *pickerDataSource;
#property (strong, nonatomic) UIPickerView *picker;
#property (strong, nonatomic) UITextField *dummyTextField;
#end
Step three
In your viewDidLoad, call [self setupPicker]; (you'll create this method next)
Step four
Create setupPicker
- (void)setupPicker {
// init custom picker data source
self.pickerDataSource = [PickerDataSource new];
// init custom picker
self.picker = [UIPickerView new];
// set the picker's dataSource and delegate to be your custom data source
self.picker.dataSource = self.pickerDataSource;
self.picker.delegate = self.pickerDataSource;
self.picker.showsSelectionIndicator = YES;
// next step is to write this configure method getting called here
[self configurePickerSubviews];
// lastly, add the dummyTextField to your view.
[self.view addSubview:self.dummyTextField];
}
Step five
Create configurePickerSubviews
- (void)configurePickerSubviews {
// A UIPickerView must be added as an inputView to a UITextField in order to be displayed on button tap
// So you need to create a dummyTextField to do so.
self.dummyTextField = [UITextField new];
// Create a toolbar to add a done button
UIToolbar *toolBar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,0,[UIScreen mainScreen].bounds.size.width,44)];
[toolBar setBarStyle:UIBarStyleDefault];
UIBarButtonItem *done = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStylePlain target:self action:#selector(locationPressed)];
// Create a flex space so that done button will be right aligned
UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *cancel = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStylePlain target:self action:#selector(dismissPicker)];
toolBar.items = #[cancel, flex, done];
done.tintColor = [UIColor blackColor];
[self.picker addSubview:toolBar];
// Create an input view to add picker + done button as subviews
UIView *inputView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, self.picker.frame.size.height + 44)];
[self.picker setFrame:CGRectMake(0, 0, inputView.frame.size.width, inputView.frame.size.height)];
inputView.backgroundColor = [UIColor clearColor];
[inputView addSubview:self.picker];
[inputView addSubview:toolBar];
// Set custom inputView as container for picker view
self.dummyTextField.inputView = inputView;
// Hiding the textfield will hide the picker
[self.dummyTextField setHidden:YES];
}
Step six
Configure the PickerDataSource so that it is fetching the data you want to display from your source array.
Step 7
Click Run!
The UIToolbar with the 'Done' button should be added to the inputAccessoryView of the view that becomes first responder. As the UIView class inherits from UIResponder, any view can potentially contain an inputView and inputAccessoryView. So instead of manually performing the animations programmatically, you could use the default animation behaviour that comes with the UIResponder's keyboard show/hide animation.
Subclass a UIView and override the inputView and inputAccessoryView properties and make them readwrite. In this example, I will subclass a UITableViewCell.
// FirstResponderTableViewCell.h
#interface FirstResponderTableViewCell : UITableViewCell
#property (readwrite, strong, nonatomic) UIView *inputView;
#property (readwrite, strong, nonatomic) UIView *inputAccessoryView;
#end
Override canBecomeFirstResponder in your subclass' implementation.
// FirstResponderTableViewCell.m
- (BOOL)canBecomeFirstResponder {
return YES;
}
In your view controller, create and assign the picker view and input accessory toolbar
// MyViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
UIPickerView *pickerView = [[UIPickerView alloc] init];
UIToolbar *accessoryToolbar = [UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
// Configure toolbar .....
// note: myFirstResponderTableViewCell is an IBOutlet to a static cell in storyboard of type FirstResponderTableViewCell
self.myFirstResponderTableViewCell.inputView = pickerView;
self.myFirstResponderTableViewCell.inputAccessoryView = accessoryToolbar;
}
Don't forget to assign first responder to the view when required (e.g. inside - tableView:didSelectRowAtIndexPath:)
[self.myFirstResponderTableViewCell becomeFirstResponder];
Hope this helps.

I have a problem with UIPickerView. Following a tutorial on YT I created a UIPickerView in a popover after tapping on a textfield.
Everything looks fine, but the UIPickerView acts kind of strange. If I just tap on a row i want to select, it rolls up/down normally to this specific row and makes a selection. But if I try to scroll with my finger it doesn't roll as smooth as it should with a momentum and it doesn't snap on any of the rows. It also doesn't make a selection, but it makes a sound like it does. Worst of all, the picker doesn't seem to care about the number of rows and I can roll up and down as far as I want, although there are no selectable rows anymore.
Here is my code.
decayStatesArray contains four simple String-objects. The UITextfield und the activeDecayString are used in the "donePressed"-methode.
The main function:
-(void)showPicker:(UITextField *)textField {
activeTextfield = textField;
//for the default sizes of a UIPickerView
decayStatePicker = [[UIPickerView alloc] init];
UIViewController *popOverContent = [[UIViewController alloc] init];
UIView *popOverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [decayStatePicker frame].size.width, [decayStatePicker frame].size.height+44)];
decayStatePicker = [[UIPickerView alloc] initWithFrame:CGRectMake([popOverView frame].origin.x, [popOverView frame].origin.y + 44, 0, 0)];
pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake([popOverView frame].origin.x, [popOverView frame].origin.y, [popOverView frame].size.width, 44)];
[decayStatePicker setDataSource:self];
[decayStatePicker setDelegate:self];
[decayStatePicker setShowsSelectionIndicator:YES];
[decayStatePicker selectRow:0 inComponent:0 animated:YES];
//Create Toolbar
[pickerToolbar setBarStyle:UIBarStyleBlackTranslucent];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(donePressed)];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(cancelPressed)];
[pickerToolbar setItems:[NSArray arrayWithObjects:flexibleSpace, doneButton, cancelButton, nil]];
[popOverView addSubview:decayStatePicker];
[popOverView addSubview:pickerToolbar];
[popOverContent setView:popOverView];
pickerPopoverController = [[UIPopoverController alloc] initWithContentViewController:popOverContent];
pickerPopoverController.popoverContentSize = CGSizeMake([popOverView frame].size.width, [popOverView frame].size.height);
[pickerPopoverController presentPopoverFromRect:[textField frame] inView:[self view] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
The delegate methodes:
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent: (NSInteger)component {
return [decayStatesArray count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
return [decayStatesArray objectAtIndex:row];
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
if ([pickerView isEqual:decayStatePicker]) {
NSLog(#"The Picker is: %#", pickerView);
NSLog(#"The item is: %#", [decayStatesArray objectAtIndex:row]);
}
activeDecayString = [decayStatesArray objectAtIndex:row];
}
I have one .xib in which I have a view that has a UISegmentedControl and I am adding them programmatically.
In appdelegate I have written the code for adding toolbar and there's event.
On toolbar click the UISegmentedControl is loaded from the given mutablearray.
What I want to do is: when I click on toolbar button the value of UISegmentedControl cannot be changed.
I have written a method for adding UISegment and its value. Every time on toolbar button click, I call the method.
Method for creating UISegmentedControl:
delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
NSMutableArray *itemArray = [[NSMutableArray alloc] init];
itemArrayforID = [[NSMutableArray alloc] init];
itemArrayforImage = [[NSMutableArray alloc] init];
bool isfirst = true;
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
[segmentedControl removeFromSuperview];
int temp =0;
NSLog(#"row count : %d",delegate.TopMenus.count);
for(int i=0;i<delegate.TopMenus.count;i++)
{
delegate.curTopsMenu = [delegate.TopMenus objectAtIndex:i];
NSLog(#"toolbar click : %#",delegate.toolbarbtnclick);
NSLog(#"parent_id : %#",[delegate.curTopsMenu valueForKey:#"parent_id"]);
if([delegate.toolbarbtnclick isEqualToString:[delegate.curTopsMenu valueForKey:#"parent_id"]])
{
int aaa = [[delegate.curTopsMenu valueForKey:#"top_menu_id"] intValue];
if(isfirst)
{
MenuLoadID = [NSString stringWithFormat:#"%d",aaa];
isfirst =false;
}
NSString *TEXT = [delegate.curTopsMenu valueForKey:#"top_menu_text"];
NSString *TEXTID = [delegate.curTopsMenu valueForKey:#"top_menu_id"];
NSString *SelectIMG = [delegate.curTopsMenu valueForKey:#"image_path"];
NSLog(#" TEXT : %# and TEXTID : %#",TEXT,TEXTID);
[itemArray insertObject:TEXT atIndex:temp];
[itemArrayforID insertObject:TEXTID atIndex:temp];
[itemArrayforImage insertObject:SelectIMG atIndex:temp];
temp++;
}
}
segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
[segmentedControl removeFromSuperview];
segmentedControl.frame = CGRectMake(0, 100, 320, 40);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.selectedSegmentIndex = 0;
[segmentedControl addTarget:self action:#selector(changeSegment:) forControlEvents:UIControlEventValueChanged];
UIImage *segmentSelected = [[UIImage imageNamed:#"games-on.png"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
UIImage *segmentUnselected = [[UIImage imageNamed:#"games-ho.png"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UISegmentedControl appearance] setBackgroundImage:segmentUnselected
forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setBackgroundImage:segmentSelected
forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
[self.navigationController.view addSubview:segmentedControl];
[segmentedControl release];
segmentSelected = nil;
[itemArray release];
[self MenuRowCount];
Code for toolbar button click:
ViewController *VC = [[ViewController alloc] init];
[VC LoadTopMenuFromBottmClick];
Your question could be more clear, but here's my best guess at an answer. This assumes the UISegmentedControl is a property called yourSegmentedControl and has been allocated (preferably by a proper getter).
Update enabled/disabled:
[self.yourSegmentedControl setEnabled:aBOOL forSegmentAtIndex:anInt];
Update title:
[self.yourSegmentedControl setTitle:aString forSegmentAtIndex:anInt];
That said, your code could be simpler. If you put the UISegmentedControl in the UIViewController rather than the appDelegate you can take advantage of using the toolbarItems property to attach the control to the navigation controller. This next code isn't exactly your question, but may be instructive:
#interface StocksTableViewController()
#property (nonatomic, strong) IBOutlet UISegmentedControl *stockFilterSegmentedControl;
#end
#implementation StocksTableViewController
#synthesize stockFilterSegmentedControl = _stockFilterSegmentedControl;
- (UISegmentedControl*)stockFilterSegmentedControl {
if (!_stockFilterSegmentedControl) {
_stockFilterSegmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"All",#"Holdings", #"To Do", nil]];
[_stockFilterSegmentedControl addTarget:self action:#selector(stockFilterControlPressed:) forControlEvents:UIControlEventValueChanged];
_stockFilterSegmentedControl.selectedSegmentIndex = 0;
_stockFilterSegmentedControl.autoresizingMask = UIViewAutoresizingFlexibleHeight;
_stockFilterSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
}
return _stockFilterSegmentedControl;
}
- (NSArray*)navFooterToolbarArray {
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:self.stockFilterSegmentedControl];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *refresh = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refresh:)];
return [NSArray arrayWithObjects:flexibleSpace, barButtonItem, flexibleSpace, refresh, nil];
}
- (void)viewDidLoad {
[super viewDidLoad];
self.toolbarItems = [self navFooterToolbarArray];
}
Enjoy,
