How to add button on UITableViewCell

Question

I have a pre-populated UITableViewCell on which cell have a Label and UITextField. Suppose I have a cell with label "map" and I want to add button on that cell how can I do this?
I tried but this is not working.
Here is the code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"rateSheetCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }
    if (indexPath.row == 0)
    {
        ((UILabel*)[cell viewWithTag:100]).text = @"Title";
        ((UITextField*)[cell viewWithTag:101]).placeholder = @"Title";
        ((UITextField*)[cell viewWithTag:101]).text = arrayResourceColumns[indexPath.section][indexPath.row][@"resource_title"];
        ((UITextField*)[cell viewWithTag:101]).keyboardType = UIKeyboardTypeDefault;
    }
    else
    {
        if([arrayResourceColumns[indexPath.section][indexPath.row][@"label"] isEqualToString:@"OT ($)"]){

            NSInteger desiredLabel = (NSInteger)(arrayResourceColumns[indexPath.section][indexPath.row][@"label"]);

            //NSString *desiredLabel = arrayResourceColumns[indexPath.section][indexPath.row][@"label"];
            NSLog(@"Label is>>>>--------%ld", (long)desiredLabel);

            if (indexPath.row == desiredLabel ) {
                UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
                [b setFrame:CGRectMake(0, 0, 50, 50)];
            }


        }
        ((UILabel*)[cell viewWithTag:100]).text = arrayResourceColumns[indexPath.section][indexPath.row][@"label"];
        ((UITextField*)[cell viewWithTag:101]).placeholder = ((UILabel*)[cell viewWithTag:100]).text;
        ((UITextField*)[cell viewWithTag:101]).text = arrayResourceColumns[indexPath.section][indexPath.row][@"attribute_value"];

        if (indexPath.row == [arrayResourceColumns[indexPath.section] count] - 1)
        {
            ((UITextField*)[cell viewWithTag:101]).enabled = NO;
        }
    }
}

Solution

There is a few ways to add button on UITAbleViewCell:
1) If you are using Storyboards you can create cell prototype with button and than you can access this button with tag property
2) Subclass UITableViewCell and add button on init
3) Add button to cell in tableView:cellForRowAtIndexPath: method

Here is a tutorial how to customize UITableViewCell with Storyboards
