Segmented Control not calling method

Question

I'm having trouble implementing a Segmented Control. I believe I have everything hooked up, but the method is not being called when I click on either side of the Segmented Control.

Header File

    #import <UIKit/UIKit.h>
#import "ServiceConnector.h"
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMessageComposeViewController.h>
#import <AddressBook/AddressBook.h>
#import "Global.h"

@interface ContactInfo : NSObject

@property char group;
@property (nonatomic, retain) NSString* firstName;
@property (nonatomic, retain) NSString* lastName;
@property (nonatomic, retain) NSString* phoneNumber;
@property int isSelected;

@end

@interface Friends : UIViewController<UITableViewDataSource, UITableViewDelegate, ServiceConnectorDelegate, MFMessageComposeViewControllerDelegate>{
    UISegmentedControl *segmentedControl;
}

@property (nonatomic, retain) IBOutlet UITableView* tblFriends;
@property (nonatomic, retain) IBOutlet UIButton* btnAdd;
@property (nonatomic, retain) IBOutlet UIButton* btnInvite;
@property (nonatomic, retain) IBOutlet UIButton* btnDone;

@property (nonatomic, retain) NSMutableArray* contactList;
@property (nonatomic, retain) NSMutableArray* contactGroup;
@property (nonatomic, retain) NSMutableArray* friendList;
@property (nonatomic, retain) NSString* modeStr;

@property (nonatomic,retain) IBOutlet UISegmentedControl *segmentedControl;

- (IBAction) InviteClicked;
- (IBAction) AddClicked;
- (IBAction) DoneClicked;
- (IBAction)segmentSwitch;
- (void) sendSMS:(NSString*) phoneNumber;
- (void) sendInviteSMS:(NSMutableArray*) resipients;
- (void) getContacts;
- (void) groupFromContacts;
- (void) groupFromFriends;

// table delegates
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;

// service connector delegate
- (void)requestReturnedData:(NSData*)data;

//message delegate
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result;

@end

Simplified version of implementation (methods have been removed)

    #import "Friends.h"
#import "JSONKit.h"

@interface Friends ()

@end

@implementation ContactInfo

@end

@implementation Friends
@synthesize segmentedControl;




- (void)viewDidLoad
{
    _friendList = [[NSMutableArray alloc] init];
    _contactList = [[NSMutableArray alloc] init];
    [self AddClicked];
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (void) dealloc
{
    [segmentedControl release];
    [_friendList release];
    [_contactList release];
    [super dealloc];
}

- (IBAction)segmentSwitch {
    switch (self.segmentedControl.selectedSegmentIndex) {
        case 0:
            [self AddClicked];
            break;
        case 1:
            [self InviteClicked];
            break;

        default:
            break;
    }

}

@end

Here is connection inspector for the Segmented Control

You need to hook the control up to the "Value Changed" event, not the "Touch Up Inside" event.
