4 cell = tvCell;
5 self.tvCell = nil;
6 }
There's some code from an Apple example of using your own "custom cell XIB" to create cells in a UITableView.
It appears to work... but I think I would do better to actually UNDERSTAND what is being done there.
Why isn't line #3 assigning the value TO something?
cell = [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil];
(In fact, cell and tvCell aren't being used at all.)
Why is line #4 assigning using tvCell when nothing has been put it in at all, yet?
Why is line #5 nulling out the tvCell that I need?
Why is "@property (nonatomic, assign) IBOutlet UITableViewCell *tvCell;" using assign, not retain?
About the only thing I can't get working correctly is when I put a disclosure-button on my custom cell XIB. Is there a way for me to detect when the user has clicked on it? (Hopefully, without using 100s of TAGs.)
