UITableViewController and detecting touches

Question

I have a UITableViewController and want to detect touches.

Basically, I want the user to be able to hold down a touch for 3 seconds, when they let go I want to pop up a small view with a few options for the table.

I've tried this...

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
 self.lastTouch = [event timestamp];
 NSLog(@"TLC.touchesBegan:touchBeginEndInterval %f", self.lastTouch);
}  

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
 NSTimeInterval touchBeginEndInterval = [event timestamp] - self.lastTouch
 NSLog(@"TLC.touchesEnded:touchBeginEndInterval %f %f", self.lastTouch, touchBeginEndInterval);
}

And it isn't picking up my touches at all...

Any ideas about the best way to implement this?

Answer 1

TableViews have sort of a "touch" delegate method. Implement this method for your tableView delegate:

// What happens when a row is touched
- (void)tableView:(UITableView *)table didSelectRowAtIndexPath:(NSIndexPath *)indexPath {}

You shouldn't make them press for 3 seconds... just use the standard.

Answer 2

Assuming that code comes from your UITableViewController subclass ... UIViewControllers don't receive methods like touchesBegan:withEvent. Only UIResponders like UIView an its subclasses like UITableView do. So you are trying to get the touches in the wrong place.

What are you trying to accomplish? Do you want to respond to touches in the UITableView or in a UITableViewCell? In case of the latter, you can deal with the touches in your custom cell implementation.
