Question

I want to use In-App purchase. Please, help me with NSUserDefaults.

I have:

free = [[NSArray alloc] initWithObjects:@"Beer", @"Ice-Cream", nil];


paid = [[NSArray alloc] initWithObjects:@"Beer", @"Ice-Cream", @"Pizza", @"Hot-dog", @"Candy", nil];

Now, if user successful purchased my product, i have this code:

  [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"isProUpgradePurchased" ];
  [[NSUserDefaults standardUserDefaults] synchronize];

As default, my UITableView, loads FREE NSArray, how can I creat a NSUserDefaults and call my UITableView to load PAID NSArrary. Thank You in advance

Answer 1

in tableView delegate method do this:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
  if([[NSUserDefaults standardUserDefaults] ObjectforKey:@"isProUpgradePurchased"])
  {
     return [paid count];
  }
  else
  {
     return [free count];
  }
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
   ..............
   if([[NSUserDefaults standardUserDefaults] ObjectforKey:@"isProUpgradePurchased"])
  {
     cell.titleLabel.text = [paid ObjectAtIndex:indexPath.row];
  }
  else
  {
     cell.titleLabel.text = [free ObjectAtIndex:indexPath.row];
  }
}
