YOU CAN USE SWIPE TO DELETE FEATURE. THIS CAN BE DOEN IN FOLLOWING WAY.

you need to implement following 3 delegate method of tableView.

tableView:commitEditingStyle:forRowAtIndexPath:
tableView:canEditRowAtIndexPath:
tableView:editingStyleForRowAtIndexPath:

In method 

tableView:editingStyleForRowAtIndexPath:

RETURN TYPE SHOULD BE 

UITableViewCellEditingStyleDelete.

You just need to set the editing property of the UITableView, in your UITableViewController implement something like;

- (void) editingButtonPressed:(id)sender {
  if([self isEditing]) {
    [sender setText:@"Edit" forState:UIControlStateNormal];
    [self setEditing:NO animated:YES];
  } else {
    [sender setText:@"Done" forState:UIControlStateNormal];
    [self setEditing:YES animated:YES];
  }
}

And hook that up to your button or image and replace the setText with setImage if you have no text.

Here is my init method for a UITableViewController using a custom UIToolbar which adds two buttons to the navigation bar in place of the right navigation bar button.

- (id) init {

    [super initWithStyle:UITableViewStyleGrouped];

    UIBarButtonItem *email = [[[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"Email.png"] style:UIBarButtonItemStyleBordered target:self action:@selector(composeEmail:)] autorelease];
    UIBarButtonItem *bookmark = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addBookmark:)] autorelease];
    [bookmark setStyle:UIBarButtonItemStyleBordered];

    CustomToolbar *buttonToolbar = [[CustomToolbar alloc] initWithFrame:CGRectMake(0, 0, 93, 45)];
    [buttonToolbar setBarStyle:UIBarStyleBlackTranslucent];
    [buttonToolbar setItems:[NSArray arrayWithObjects:email, bookmark, nil] animated:NO];

    [[self navigationItem] setTitle:@"Table with Custom Toolbar"];
    [[self navigationItem] setRightBarButtonItem:[[[UIBarButtonItem alloc] initWithCustomView:buttonToolbar] autorelease]];

    [buttonToolbar release];

    return self;
}

When creating the buttons I use action:@selector(customMethodName) when creating the buttons to hook up my methods to the button actions in this case composeEmail and addBookmark which load the new views for those tasks.

You have to add UIButton instance to that imageview and implement a method that will execute when an event occurs on that UIButton.

Code for the method will look like,

if(tableView.editing)
[tableView setEditing:NO animated:YES]
else
[tableView setEditing:YES animated:YES]

Read UITableView Documentation for more info.

you can add a button on your imageview and on that button click set your tableviewediting to yes.

here's the code how to add a imageview and button:-

UIImageView *imageView2=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
    [imageView2 setImage:[UIImage imageNamed:@"bottom bar_gda.png"]];
    [self.view addSubview:imageView2];
    [self.view bringSubviewToFront:imageView2];
    UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [deleteButton setFrame:CGRectMake(280, 3, 26, 36)];
    deleteButton.contentMode = UIViewContentModeScaleAspectFill;     
    UIImage *newImage12 = [UIImage imageNamed:@"check.png"];
    [deleteButton setBackgroundImage:newImage12 forState:UIControlStateNormal];
    [deleteButton setBackgroundImage:newImage12 forState:UIControlStateHighlighted];
    [deleteButton addTarget:self action:@selector(editmethod:) forControlEvents:UIControlEventTouchUpInside];
    [imageView2 addSubview:deleteButton];
