Question

I have a table view, and I use UILongPressGestureRecognizer on table view cell to show a context menu over the cell to allow user perform some extra functionality. Everything is work well in iOS 5.1, but when I test in iOS 5 and 4.3, the event is not fired.

Does anyone know how to solve this problem please help me, thanks in advance.

Below is my code:

in tableViewCell.h: add UIGestureRecognizerDelegate

in tableViewCell.m

UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] 
                                                     initWithTarget:self action:@selector(handleLongPress:)];
longPressRecognizer.minimumPressDuration = 1.5;
longPressRecognizer.numberOfTouchesRequired = 1;
longPressRecognizer.numberOfTapsRequired = 0;
longPressRecognizer.delegate = self;

[self addGestureRecognizer:longPressRecognizer];
[longPressRecognizer release];

// Method to handle event

- (void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{    
    if (gestureRecognizer.state == UIGestureRecognizerStateBegan) 
    {
        // Do something.
    }
}

After spending 1.5 days on this issue, I discover that somehow the tableView receives long press event but tableViewCell does not on iOS 5/4.3 . So I fixed this issue by adding UILongPressGuestureRecognizer to tableView then in the long press event handler then call tableViewCell to show the context menu, and it works.
