iphone: Making pointer to UITableViewCell crashing app?

Question

I have a UITableView with about 20 cells. I wanted to make a pointer to three of those cells, so I set up a property for those, then pointed them to those cells:

if ([item.title isEqualToString:@"Test1"]) {
  test1 = cell;
} else if ([item.title isEqualToString:@"test2"]) {
  test2 = cell;
}

If I scroll up and down in my table view over and over it will crash my app. But, removing this pointer code fixes the crashing issue.

Why would making a pointer to a cell make my app crash?

Edit:

if ([item.title isEqualToString:@"Test1"]) {
        self.test1 = cell;
} else if ([item.title isEqualToString:@"test2"]) {
        self.test2 = cell;
}

I just updated my code to use self. and it seems to fix the crashing issue. Could this be true?

You have to use self. if you want to call the property, if no, you are just calling your instance variable.

And with property, I think that it already supports you with (retain) then you really owns the test1 and test2 and later on, you can call method on them
