How to Implement Swipe Gesture in Down Direction for UITableView?

I tried the following code:

UISwipeGestureRecognizer *showBar = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(gestureShowBar:)];
showBar.direction = UISwipeGestureRecognizerDirectionDown;
showBar.numberOfTouchesRequired = 2;
[self.tableview addGestureRecognizer:showBar];

with no luck! The tableview tends to scroll when I swipe is performed using two fingers. So, I tried disabling multi-touch on tableview and let the superview handle the gesture:

UISwipeGestureRecognizer *showBar = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(gestureShowBar:)];
showBar.direction = UISwipeGestureRecognizerDirectionDown;
showBar.numberOfTouchesRequired = 2;
[self.view addGestureRecognizer:showBar];

Again, it doesn't work! I really wonder why a tableview wil开发者_Go百科l respond to two finger swipe although multi-touch is not enabled!
