UITableView and UISegmentedControl

I am new in iPhone developing. I have one UITableView with three Section and each Section has three rows. And I have one UISegmentedControl with three index.the tableview is hidden initially .when I select any index of segmentIndex then its display the tableview with three section. But my question is that when I select index of segmented control then its display the tableView with only one section and other two section is hide in the tableView.How to do it please answer
Here is my code

#import "DetailViewController.h"


@interface DetailViewController ()

@end

@implementation DetailViewController

@synthesize tblView;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
    // Custom initialization
    }
    return self;
}


- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    //Customize tableview
    tblView = [[UITableView alloc] init];
    firstName = [NSArray arrayWithObjects:@"Parth",@"Bhadresh",@"Marshal", nil];
    middleName = [NSArray      arrayWithObjects:@"Dipakbhai",@"Dineshbhai",@"Mansukhbhai",nil];
    lastName = [NSArray arrayWithObjects:@"Patel",@"Laiya",@"Kaneria", nil];
    tblView.delegate = self;
    tblView.dataSource = self;
}

-(void)viewWillAppear:(BOOL)animated
{
    sgmtControl.frame = CGRectMake(17, 180, 285, 44);    
    tblView.frame = CGRectMake(0, 0, 320, 364);
    tblView.hidden = YES;
    [self.view addSubview:tblView];
}

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:myIdentifier];
    }

    switch (indexPath.section)
    {
        case 0:
            cell.textLabel.text =[firstName objectAtIndex:indexPath.row];
            break;

A little modification in Mountain Lion's code to make it more generic and to remove switches

@synthesize currentArray;
.
.
.
.

- (void)viewDidLoad
{
      .
      .
      .
      //ALLOCATE currentArray
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return currentArray.count;
}

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection: (NSInteger)section
{
    switch (sgmtControl.selectedSegmentIndex)
    {
        case 0:
            return @"FirstName";
            break;
        case 1:
            return @"MiddleName";
            break;
        case 2:
            return @"LastName";
            break;
    }
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *myIdentifier = @"MyIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:myIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:myIdentifier];
    }

   cell.textLabel.text =[currentArray objectAtIndex:indexPath.row];
   return cell;
}
-(IBAction)changeSegement:(id)sender
{
    if(sgmtControl.selectedSegmentIndex == 0)
    {
        currentArray = firstName;
    }
    else if (sgmtControl.selectedSegmentIndex == 1)
    {
        currentArray = middleName;
    }
    else if (sgmtControl.selectedSegmentIndex == 2)
    {
        currentArray = lastName;
    }
    tblView.hidden = NO;
    [tblView reloadData];
}

Do like this,

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    switch (sgmtControl.selectedSegmentIndex)
    {
        case 0:
            return [firstName count];
            break;
        case 1:
            return [middleName count];
            break;
        case 2:
            return [lastName count];
            break;
    }
    return 0;
}

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection: (NSInteger)section
{
    switch (sgmtControl.selectedSegmentIndex)
    {
        case 0:
            return @"FirstName";
            break;
        case 1:
            return @"MiddleName";
            break;
        case 2:
            return @"LastName";
            break;
    }
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *myIdentifier = @"MyIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:myIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:myIdentifier];
    }

    switch (sgmtControl.selectedSegmentIndex)
    {
        case 0:
            cell.textLabel.text =[firstName objectAtIndex:indexPath.row];
            break;
        case 1:
            cell.textLabel.text = [middleName objectAtIndex:indexPath.row];
            break;
        case 2:
            cell.textLabel.text = [lastName objectAtIndex:indexPath.row];
            break;
    }
    return cell;
}
-(IBAction)changeSegement:(id)sender
{
    if(sgmtControl.selectedSegmentIndex == 0)
    {
        tblView.hidden = NO;
    }
    else if (sgmtControl.selectedSegmentIndex == 1)
    {
        tblView.hidden = NO;
    }
    else if (sgmtControl.selectedSegmentIndex == 2)
    {
        tblView.hidden = NO;
    }
    [tblView reloadData];
}

I believe i understand what you are trying to do, you want to display different table view cells depending on which of the button segments is selected.

You need to have your cellForRowAtIndexPath check which segment is selected and return the correct set of cells.

When the user changes the segmented button, have changeSegment: store the selected segment in an instance variable. Then have it call [self reloadData];

#import "DetailViewController.h"


@interface DetailViewController ()

    NSArray *names;
    NSInteger segIndex;

Try this

}

        break;
    case 1:
        return 3;
        break;
    case 2:
        return 3;
        break;
}
return 0;
}

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection: (NSInteger)section
{
switch (sgmtControl.selectedSegmentIndex)
{
    case 0:
        return @"FirstName";
        break;
    case 1:
        return @"MiddleName";
        break;
    case 2:
        return @"LastName";
        break;
   }
 }

  -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *myIdentifier = @"MyIdentifier";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:myIdentifier];
if (cell == nil)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:myIdentifier];
}

switch (sgmtControl.selectedSegmentIndex)
{
    case 0:
        cell.textLabel.text =[firstName objectAtIndex:indexPath.row];
        break;
    case 1:
