Answer 1

add target at the time of segmentedControl creation like below
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
in that selector
-(IBAction) segmentAction:(id)sender{
UISegmentedControl *segmentedControl = (UISegmentedControl *)sender;
NSLog(#"Segment clicked: %d", segmentedControl.selectedSegmentIndex);
switch (segmentedControl.selectedSegmentIndex) {
case 0:
self.segmentLabel.text =#"Segment 1 selected.";
break;
case 1:
self.segmentLabel.text =#"Segment 2 selected.";
break;
default:
break;
}

You have to make 3 buttons and add them to an UIToolbar.
- (void)viewDidLoad
{
[super viewDidLoad];
// create a toolbar to have the buttons at the right side of the navigationBar
UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 150, 44.01)];
toolbar.tintColor = [UIColor clearColor];
[toolbar setTranslucent:YES];
// create the array to hold the buttons, which then gets added to the toolbar
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];
// Create button1
UIBarButtonItem *button1 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemSearch target:self action:#selector(button1Pressed)];
[buttons addObject:button1];
[button1 release];
// Create button2
UIBarButtonItem *button2 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCompose target:self action:#selector(button2Pressed)];
[buttons addObject:button2];
[button2 release];
// Create button3
UIBarButtonItem *button3 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemBookmarks target:self action:#selector(button3Pressed)];
[buttons addObject:button3];
[button3 release];
// stick the buttons in the toolbar
[toolbar setItems:buttons animated:NO];
//self.toolbarItems = buttons;
[buttons release];
// and put the toolbar in the nav bar
[[self navigationItem] setRightBarButtonItem:[[[UIBarButtonItem alloc] initWithCustomView:toolbar] autorelease]];
[toolbar release];
}
...
- (void)button1Pressed
{
//do stuff
}
- (void)button2Pressed
{
//do stuff
}
- (void)button3Pressed
{
//do stuff
}
