title: How do I remove or stop a button in table view from working after registered amount of taps
body: <p>I have a button in a table view that adds rows. After a maximum of five rows I want to stop the user adding anymore.  Currently I show an alert after button recives 5 taps.</p>
  
  <p>How can I  stop the user from using the button past this point?  Setting to hidden wont work as its a custom subclass and <code>property hidden</code> is not found on the class</p>
  
  <pre><code>- (void)viewDidLoad
  {
  
  [super viewDidLoad];
  
  UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
  titleLabel.backgroundColor = [UIColor clearColor];
  titleLabel.textColor = [UIColor whiteColor];
  titleLabel.shadowColor = [UIColor darkGrayColor];
  titleLabel.text = self.distributionBoard.dbRef;
  titleLabel.font = [UIFont boldSystemFontOfSize:15.0f];
  [titleLabel sizeToFit];
  self.navigationItem.titleView = titleLabel;
  
  self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneButtonPressed:)];
  
  // Add new appliance button to the table view's footer view
  UIView *footerView = [[UIView alloc] initWithFrame:CGRectMake(10.0f, 0, 300.0f, 100.0f)];  
  footerView.backgroundColor = [UIColor clearColor];
