}
- (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];
}
mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
mimageButton.frame=CGRectMake(10, 10, 30, 50);
mimageButton.tag = 1;
onButtonView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 50)];
onButtonView.tag = 2;
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
[mimageButton setBackgroundImage:[onButtonView.image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateNormal];
[cell.contentView addSubview:mimageButton];
[mimageButton addTarget:self action:#selector(changeMapType:) forControlEvents: UIControlEventTouchUpInside];
[onButtonView release];
// Configure the cell...
return cell;
}

Define you tableview delegate like this.
- (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];
mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
mimageButton.frame=CGRectMake(10, 10, 30, 50);
mimageButton.tag = 1;
onButtonView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 50)];
onButtonView.tag = 2;
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
[mimageButton setBackgroundImage:[onButtonView.image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateNormal];
[cell.contentView addSubview:mimageButton];
[mimageButton addTarget:self action:#selector(changeMapType:) forControlEvents: UIControlEventTouchUpInside];
[onButtonView release];
}
// Configure the cell...
return cell;
}

Here is the code:-
Add this in cellForRowAtIndexPath method. And also set flag variable in your target method for togglebutton.
if(flagButton)
{
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
}
else
{
onButtonView.image = [UIImage imageNamed:#"alarm_OFF.png"];
}

I tried this different approach, and it worked.
While configuring the button,
- (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];
mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
mimageButton.frame=CGRectMake(10, 10, 30, 50);
mimageButton.tag = 1;
[tempButton setImage:[UIImage imageNamed:#"alarm_ON.png"] forState:UIControlStateNormal];
[tempButton setImage:[UIImage imageNamed:#"alarm_OF.png"] forState:UIControlStateSelected];
[cell.contentView addSubview:mimageButton];
[mimageButton addTarget:self action:#selector(changeMapType:) forControlEvents: UIControlEventTouchUpInside];
}
// Configure the cell...
return cell;
}
And in changeMapType: method,
-(void)changeMapType:(id)sender{
changeimagetype =!changeimagetype;
sender.selected = changeimagetype;
}
