- (UITableViewCell)tableView:(UITableView)tableView
cellForRowAtIndexPath:(NSIndexPath*)indexPath {
static NSString *CellTableIdentifier = @"CellTableIdentifier ";
static NSUInteger nTag = 100;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
CellTableIdentifier];
if (cell == nil) {
CGRect cellFrame = CGRectMake(0, 0, 300, 65);
cell = [[[UITableViewCell alloc] initWithFrame:cellFrame
reuseIdentifier:CellTableIdentifier] autorelease];
CGRect labelRect = CGRectMake(10, 26, 190, 15);
UILabel *label = [[UILabel alloc] initWithFrame:labelRect];
label.textAlignment = UITextAlignmentLeft;
label.font = [UIFont boldSystemFontOfSize:12];
// set all label tags to 10 so the label can be found in the subviews
label.tag = 10;
[cell.contentView addSubview:label];
[label release];
CGRect buttonRect = CGRectMake(210, 25, 65, 25);
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = buttonRect;
// set the button title here if it will always be the same
[button setTitle:@"Action" forState:UIControlStateNormal];
button.tag = nTag++;
[button addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventTouchUpInside];
// make sure the button is the lowest subview so it's easy to find
[cell.contentView insertSubview:button atIndex:0];
// button will be autoreleased so don't release it here
// the label text and button title come from an array of NSDictionary in this example
NSUInteger row = [indexPath row];
NSDictionary *rowData = [self.data objectAtIndex:row];
UILabel *thisLabel = (UILabel*)[cell.contentView viewWithTag:10];
thisLabel.text = [rowData objectForKey:@"Text"];
// set the button title here if it depends on the row
UIButton *thisButton = [[cell.contentView subviews] objectAtIndex:0];
[thisButton setTitle:[rowData objectForKey:@"Button"] forState:UIControlStateNormal];
return cell;
- (IBAction)myAction:(id)sender {
UIButton *theSender = sender;
UITableViewCell *cell;
NSUInteger row = 0;
for (cell in [theTableView visibleCells]) {
UIButton *thisButton = [[cell.contentView subviews] objectAtIndex:0];
if (thisButton.tag == theSender.tag) {
row = [[theTableView indexPathForCell:cell] row];
break;
NSLog(@"myAction: row=%d", row);
