You can do this by simply implementing the following @selector for your UIButton in UITableViewCell.

- (void)btnSetMode:(id)sender
{
    UIButton *btn = (UIButton *)sender;
    if (btn.tag == 0)
    {
        [btn setTitle:@"Present" forState:UIControlStateNormal];
        btn.tag = 1;
        // Define your required task...
    }
    else if (btn.tag == 1)
    {
        [btn setTitle:@"Absent" forState:UIControlStateNormal];
        btn.tag = 2;
        // Define your required task...
    }
    else if (btn.tag == 2)
    {
        [btn setTitle:@"Leave" forState:UIControlStateNormal];
        btn.tag = 3;
        // Define your required task...
    }
    else if (btn.tag == 3)
    {
        [btn setTitle:@"Attendance" forState:UIControlStateNormal];
        btn.tag = 0;
        // Define your required task...
    }
}

Your single button will do all the required task as you wanted.

If you have An UIButton in your tableViewCell then add Target to your UIButton and set button Tag with indexPath.row in cellForRowAtIndexPath like-

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    attendanceListTableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"cell"];

    cell.studentNameLbl.text=[NSString stringWithFormat:@"Student %ld",(long)indexPath.row];

    cell.editBtn.tag=indexPath.row;

    [cell.editBtn setTitle:[attandanceArry objectAtIndex:indexPath.row] forState:UIControlStateNormal];

    [cell.editBtn addTarget:self action:@selector(editAttendance:) forControlEvents:UIControlEventTouchUpInside];

    return cell;
}
-(void)editAttendance:(id)sender{

    UIButton *btn=(UIButton*)sender;

    if ([btn.titleLabel.text isEqualToString:@"P"]) {
        [btn setTitle:@"A" forState:UIControlStateNormal];
        [attandanceArry replaceObjectAtIndex:btn.tag withObject:@"A"];
    }else if ([btn.titleLabel.text isEqualToString:@"A"]) {
        [btn setTitle:@"L" forState:UIControlStateNormal];
        [attandanceArry replaceObjectAtIndex:btn.tag withObject:@"L"];
    }else if ([btn.titleLabel.text isEqualToString:@"L"]) {
        [btn setTitle:@"P" forState:UIControlStateNormal];
        [attandanceArry replaceObjectAtIndex:btn.tag withObject:@"P"];
    }

}

In this attandanceArry is mutableArray having all default value is "P" with capacity of your number of students and editBtn is your cell UIButton. Here I use custom tableViewCell class i.e. attendanceListTableViewCell class having UIButton. At the end you can use attandanceArry as result array when you complete editing attendance. I hope this will help you...:)

Is a UISegmentedControl what you are looking for?

A UISegmentedControl

See the Apple Documentation here. It can be configured in a storyboard with the correct number of segments and segment titles. When the user selects a segment it will be highlighted, and any other segments are deselected.

Change the button title and background color when it's clicked. Personally, I would use three different buttons so that all different options would be visible at the same time. UIPicker is one option too.
