UITableview Problem with button image

my problem is i have one tableview displaying four cells, in those cells i have one cutom button also. By clicking on that button the button imag开发者_JAVA技巧e has to be changed like checkmark image.

i tried but not getting properly. my req is if i click on cell at index zero that index button image has to be changed.

can anyone help me on this.

Thanks in advance.

write the selectedIndex in .h file

- (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];
    }

    if(selectedindex==indexPath.row){
        cell.accessoryType=UITableViewCellAccessoryCheckmark;
                //here you can change the backgroundimage.
button]setbackgroundImage:[UIImage imageNamed:@"1.Jpg"];
}



    return cell;
}

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

    selectedIndex=indexPath.row;
    [tableView reloadData];
}

you need to do two things

1. You need to pass a msg to button

   [comboButton setBackgroundImage:[UIImage imageNamed:@"firstImage.png"] forState:UIControlStateNormal]
   [comboButton setBackgroundImage:[UIImage imageNamed:@"second.png"] forState:UIControlStateHighlighted]
   

2. and in tableView delegate method tableView:didSelectRowAtIndexPath: set the button state to Highlighted
