Access parent view from custom cell - iphone

Question

How can I access the UIView in which I have a UITableView, from the custom cells inside that table. I cant find a method to do that.
Thanks

You can add an instance variable that points to the UITableView and set it when creating/configuring the cell (e.g. in tableView:cellForRowAtIndexPath:). Make sure that your cell does not retain the tableView though.
Knowing your cell’s tableView, call [parentTableView superView] to access the UITableView’s parent view:
#interface PropertyListingCell : UITableViewCell {
__weak id parentTableView;
}
- (void) setParentTableView:(UITableView*)tv; // parentTableView = tv;
In UITableViewController implementation:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//dequeue/create and configure your custom cell here
[cell setParentTableView:tableView];
return cell;
}
UPDATE:
If you're using recent XCode (at least 4.3) you can simply add
#property (weak) UITableView *parentTableView; // use unsafe_unretained instead of weak if you're targeting iOS 4.x
to the #interface section of your UITableViewCell's subclass. Then, when you're creating a cell (in tableView:cellForRowAtIndexPath:) set this property accordingly:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// ...
//dequeue/create and configure your custom cell here
// ...
cell.parentTableView = tableView;
return cell;
}
And in your cell class call self.parentTableView to access the tableView this cell belongs to.
