Question

I want to do an sample application where in a view i have two buttons one is COUNTRY and another is STATE.
when i click on a country button the country list should appear in a tableview class like a popup and when i click on state button state list should appear in a tableview like popup,So how can i do this please suggest with sample code.

NOTE:I should use only one TableViewcontroller class for both country and state Data list.

Here is the Code:

RootViewController.h

@interface RootViewController : UIViewController {

UIButton *btnCountry;
UIButton *btnState;

NSMutableArray *tempArray;
NSMutableArray *countryArray;
NSMutableArray *stateArray;

IBOutlet UITableView *tempTable;
}

 @property (nonatomic,retain) UIButton *btnCountry;
 @property (nonatomic,retain) UIButton *btnState;
 @property (nonatomic,retain) NSMutableArray *countryArray;
 @property (nonatomic,retain) NSMutableArray *stateArray;
@property (nonatomic,retain) NSMutableArray *tempArray;
@property (nonatomic,retain) UITableView *tempTable;


- (IBAction) showState:(id)sender;
- (IBAction) showCountry:(id)sender;

@end

RootViewController.m

@implementation RootViewController

@synthesize btnState,btnCountry, stateArray,countryArray,tempArray;
@synthesize tempTable;

#pragma mark -
#pragma mark View lifecycle


- (void)viewDidLoad {

[super viewDidLoad];

tempTable.hidden = YES;

countryArray = [[NSMutableArray alloc]initWithObjects:@"India",@"Pakistan",@"USA",nil];
stateArray = [[NSMutableArray alloc]initWithObjects:@"Gujarat",@"Maharashtra", @"Karnataka",nil];
tempArray = [[NSMutableArray alloc]init];

}



- (IBAction) showCountry:(id)sender
{
btnCountry = (UIButton *)sender;
tempArray = countryArray;
[tempTable reloadData];
if([btnCountry isSelected])
{
    tempTable.hidden = YES;
    btnCountry.selected = NO;
}
else
{
    tempTable.hidden = NO;
    btnCountry.selected = YES;
}
}


- (IBAction) showState:(id)sender
{
btnState = (UIButton *)sender;
tempArray = stateArray;
[tempTable reloadData];

if([btnState isSelected])
{
    tempTable.hidden = YES;
    btnState.selected = NO;
}
else
{
    tempTable.hidden = NO;
    btnState.selected = YES;
}
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

return 1;
}


// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section      {

return [tempArray count];
 }


// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *CellIdentifier = @"Cell";

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

cell.textLabel.text = [tempArray objectAtIndex:indexPath.row];

return cell;
}
