Show Data In Table View Using Arrays

-Make a project iTableView

- In RootViewController.h We will declare a mutable array

//

//  RootViewController.h

//  iTableView

//

//  Created by Jubayer Ahmed on 5/22/11.

//

#import <UIKit/UIKit.h>

@interface RootViewController : UITableViewController {

NSMutableArray *datas;

}

@property(nonatomic, retain) NSMutableArray *datas;

@end

- In RootViewController.m we synthesize the variable and  initialize the array

//

//  RootViewController.m

//  iTableView

#import "RootViewController.h"

@implementation RootViewController

@synthesize datas;

#pragma mark -

#pragma mark View lifecycle

- (void)viewDidLoad {

    [super viewDidLoad];

          NSMutableArray *tempArray = [[NSMutableArray alloc] initWithObjects:@"Dhaka",@"Chittagonj",@"ManikGonj",nil];

     self.datas = tempArray;

          [tempArray release];

        

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.

    // self.navigationItem.rightBarButtonItem = self.editButtonItem;

}

- In Root.h file numberOfSectionsInTableView and numberOfRowsInSection tells the table view how many sections we have and how many rows in each section.

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

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

    return 1;

}

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

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

    return [self.datas count];

}

- indexPath: The indexPath contains the section and row number for the needed cell

-cellForRowAtIndexPath: This method is called when the table view needs a cell.

// 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];

    }

   

         // Configure the cell.

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

         cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

         return cell;

}

- Finally release the the values

- (void)dealloc {

    [super dealloc];

         [datas release];

}
