Answer 1

viewDidLoad
yourTableView.allowsmultiselection=YES;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell=[tableView cellForRowAtIndexPath:indexPath];
[cell.btn setBackgroundImage:[UIImage imageNamed:#"selected-24.png"] forState:UIControlStateNormal];
NSArray *arr=[tableView indexPathsForSelectedRows];
lbl.textLabel.text=[NSString stringWithFormat:#"%d",[arr count] ];
}
in deselect
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell=[tableView cellForRowAtIndexPath:indexPath];
[cell.btn setBackgroundImage:[UIImage imageNamed:#"unselected-24.png"] forState:UIControlStateNormal];
NSArray *arr=[tableView indexPathsForSelectedRows];
lbl.textLabel.text=[NSString stringWithFormat:#"%d",[arr count] ];
}

Answer 2

Take a NSMutableArray for selelcted buttons.when you select particuler button at that time add that indexpath.row value to the array.And when you delselect the button at that time check wheateher that indexpath.row value present in that array or not ,if yes then find the index of that object and remove that object from the array.
if([array containsObject:#"value"]){
int n=[array indexOfObject:#"value"];
[array removeObjectAtIndex:n];
}
Now check the count of array as [array count];
