Question

I have an interesting trouble:

I have a NSArray which is populated with some animals name (strings). And I use this array to populate UITableView. When you press on any cell (animal), you move in a detail view and you read more about this animal. Then, I improved my app and now in UITableView the first cell is the cell which just says how many animals in the UITableView. Its like:

Animals found: 4 (first cell)

• Dog (second cell)
• Cat (third cell and etc.)
• Hamster
• Snake

The problem is, that when you press on the first cell (Animals found: 4) you move in the detail view of a random animal. It happens because in the array at index 0 there is an animal. Therefore, you move in the detail view of this animal. I don’t want to do anything when user presses the first cell. How can I reach it ?

Answer 1

I think the better solution is to represent in your model what you want to see in your views. So I would do it like this:

myModel = [NSMutableArray arrayWithObjects:@"3 animals", @"dog", @"cat", @"chicken", nil];
// here, wherever else my model is altered:
[myModel replaceObjectAtIndex:0 withObject:[NSString stringWithFormat:@"%d animals", myModel.count-1]];

Now no special logic is required anywhere else except as @Praveen-K suggests when configuring cell at indexPath.row = 0…

cell.userInteractionEnabled = NO;
