UITapGestureRecognizer conflict with didSelectRowAtIndexPath

well before i ask this i try the other solutions and it didn't work

this is my code

override func viewDidLoad() {
    super.viewDidLoad()

    let tapGesture = UITapGestureRecognizer(target: self, action: "didTouchBoard:")
    view.addGestureRecognizer(tapGesture)
    tapGesture.cancelsTouchesInView = true
}

when i click anywhere it will hide the keyboard if exist , but if i click on tableviewcell or collectionviewcell , it won't click

i try this tapGesture.cancelsTouchesInView , but not work
