How to get a UITableViewCell from one of its subviews

Question

I have a UITableView with a UITextField in each of the UITableViewCells. I have a method in my ViewController which handles the \"Did

Answer 1

Basically in this case, I would prefer you to put the IBAction method into cell instead of view controller. And then when an action is triggered, a cell send a delegate to a view controller instance.

Here is an example:

@protocol MyCellDelegate;


@interface MyCell : UITableViewCell

@property (nonatomic, weak) id delegate;

@end

@protocol MyCellDelegate 

- (void)tableViewCell:(MyCell *)cell textFieldDidFinishEditingWithText:(NSString *)text;

@end

In a implementation of a cell:

- (IBAction)itemFinishedEditing:(UITextField *)sender
{
    // You may check respondToSelector first
    [self.delegate tableViewCell:self textFieldDidFinishEditingWithText:sender.text];
}

So now a cell will pass itself and the text via the delegate method.

Suppose a view controller has set the delegate of a cell to self. Now a view controller will implement a delegate method.

In the implementation of your view controller:

- (void)tableViewCell:(MyCell *)cell textFieldDidFinishEditingWithText:(NSString *)text
{
    NSIndexPath *indexPath = [_tableView indexPathForCell:cell];
    _list.items[indexPath.row] = text;
}

This approach will also work no matter how Apple will change a view hierarchy of a table view cell.
