Customized Drop-Down list in iPhone

Hi,
I have created a drop-down list in iPhone.
Steps to create:
1) Open Xcode, create new project
2) Add new SimpleTableViewController.h , SimpleTableViewController.m and tick on xib file also in project after creating the AppDelegate files.
3) In xib file drag an UIButton and an UITableView.
4) Place the UITableView below the button as if it will appear after clicking on the button

SimpleTableViewController.xib

SimpleTableViewController.h 

#import <UIKit/UIKit.h>

#import <QuartzCore/QuartzCore.h>

@interface SimpleTableViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>{

IBOutlet UITableView *tblSimpleTable;

IBOutlet UIButton *btn;

IBOutlet UIImageView *i;

BOOL flag;

NSArray *arryData;

}

@property(nonatomic,retain)IBOutlet UITableView *tblSimpleTable;

@property(nonatomic,retain)IBOutlet UIButton *btn;

@property(nonatomic,retain)IBOutlet UIImageView *i;

-(IBAction)btnClicked;

@end

5) Make the connections in the .xib file accordingly



SimpleTableViewController.m 

#import "SimpleTableViewController.h"

@implementation SimpleTableViewController

@synthesize btn;

@synthesize tblSimpleTable;

@synthesize i;

-(IBAction)btnClicked{

if (flag==1) {

flag=0;

tblSimpleTable.hidden=NO;

i.hidden=YES;

}

else{

flag=1;

tblSimpleTable.hidden=YES;

i.hidden=NO;

}

}

// The designated initializer. Override to perform setup that is required before the view is loaded.

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {

    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {

        // Custom initialization

    }

    return self;

}

/*

// Implement loadView to create a view hierarchy programmatically, without using a nib.

- (void)loadView {

}

*/

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.

- (void)viewDidLoad {

arryData = [[NSArray alloc] initWithObjects:@"iPhone",@"iPod",@"MacBook",@"MacBook Pro",nil];

//tblSimpleTable.frame =CGRectMake(10, 10, 300, 100);

flag=1;

tblSimpleTable.hidden=YES;

btn.layer.cornerRadius=8;

tblSimpleTable.layer.cornerRadius=8;

//i=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"arrow-down.png"]];

    [super viewDidLoad];

}

/*

// Override to allow orientations other than the default portrait orientation.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    // Return YES for supported orientations

    return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

*/

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview

    // Release anything that's not essential, such as cached data

}

- (void)dealloc {

    [super dealloc];

}

#pragma mark Table view methods

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

    return 1;

}

// Customize the number of rows in the table view.

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

    return [arryData 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] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];

    }

    

    // Set up the cell...

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

    return cell;

}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

}

@end

Now Build n Run n enjoy :)
