Gesture error in uitableview cells

i have a problem with my GestureRecognizer in UITableViewCell,i have swipe-left and right Gesture, tap-hold for 2 second and pinch Gesture in tableview cell, Swipe-right for next chapter, swipe left for previous chapter,pinch for redirecting to another view-controller,and hold 2 second for a popup to show(a subview).all are implemented in a single tableview called table. My problem is every thing works fine,but after a some long period of using Gesture in the tableview it stucks the swipeGesture may be pinch also not working. but when i go to another page and came back it start normal working. and it stucks after some time also. How to solve this my code is?

    readCell *cell = (readCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    [acntView removeFromSuperview];
    UIView *popView = (UIView *)[self.view viewWithTag:106]; 
    //ViewWithTag Number should be same as used while allocating
    [popView removeFromSuperview];

}

and also when we swipe left or right the action is very slow also. Please help me.

You add a recognizer every time the routine tableView:cellForRowAtIndexPath: is called, and remove one after a gesture is processed. So after all recognizers (number of them equals number of cells) are removed, the gesture won't be recognized.

Perhaps you should not remove the recognizer in handling routine?


Your gesture recognizers apply to the whole table, yet you add them every time a cell is created!

Instead of adding the gesture recognizers to the whole table every time it creates a cell, try adding them somewhere else. Or if you mean to have the gestures in just cells, try using:

[cell addGestureRecognizer:recognizer];
