Try this sample tutorial,

ViewController.h

#import 

@interface ViewController : UIViewController
{
  NSMutableArray *arryData1;
  NSMutableArray *arryData2;
  IBOutlet UITableView *tableList;
}

@end

ViewController.m

#import "ViewController.h"

@interface ViewController ()

 @end

@implementation ViewController

-(void)viewDidLoad
{
[super viewDidLoad];

arryData1 = [[NSMutableArray alloc] initWithObjects:@"MCA",@"MBA",@"BTech",@"MTech",nil];
arryData2 = [[NSMutableArray alloc] initWithObjects:@"Objective C",@"C++",@"C#",@".net",nil];
tableList.editing=YES;

}

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

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [arryData1 count];
}

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

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] ;
}
cell.textLabel.text = [arryData1 objectAtIndex:indexPath.row];
cell.detailTextLabel.text = [arryData2 objectAtIndex:indexPath.row];
return cell;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

if (editingStyle == UITableViewCellEditingStyleDelete) {
    int index = indexPath.row;
    [arryData1 removeObjectAtIndex:index];
    [arryData2 removeObjectAtIndex:index];

    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
                     withRowAnimation:UITableViewRowAnimationFade];


}
}

- (UITableViewCellEditingStyle)tableView:(UITableView *)aTableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableList.editing)
{
    return UITableViewCellEditingStyleDelete;
}

return UITableViewCellEditingStyleNone;
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
