我有一个带有TableView和2（tap）手势识别器的UIViewController。 第一个识别器让键盘消失。第二个菜单。
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(HomeVC.dismissKeyboard))
view.addGestureRecognizer(tap)
-
@IBAction func menuBtn(sender: AnyObject) {
let menuView = (NSBundle.mainBundle().loadNibNamed("Menu", owner: self, options: nil).last) as! Menu
menuView.frame = CGRectMake(0, self.view.bounds.size.height, self.view.bounds.size.width, 100)
self.view.addSubview(menuView)
UIView.animateWithDuration(0.6, delay: 0, usingSpringWithDamping: 0.5, initialSpringVelocity: 0.8, options: .CurveEaseInOut, animations: { () -> Void in
var newMenuFrame = menuView.frame
newMenuFrame.origin.y = self.view.bounds.size.height - 63
menuView.frame = newMenuFrame
self.view.layoutIfNeeded()
}) { (success) -> Void in
let gestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(HomeVC.hideOnTap(_:)))
gestureRecognizer.numberOfTapsRequired = 1
self.view.addGestureRecognizer(gestureRecognizer)
}
}
使用手势regonizers，didSelectRowAtIndexPath将不会被调用。我该怎么做才能保持手势识别器和我的tableView。要么。如何仅为tableView停用手势识别器？非常感谢帮助。
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("You selected cell #\(indexPath.row)!")
// this is only working if both gesture recognizers are gone.
}

答案 0 :(得分：1)
设置cancelsTouchesInView可能有所帮助：
tap.cancelsTouchesInView = false
longtap.cancelsTouchesInView = false
通常，您可以让方法shouldRecognizeSimultaneouslyWithGestureRecognizer返回true并添加相应的委托来让识别器与其他识别器一起使用。
答案 1 :(得分：1)
你应该覆盖
optional func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer,
shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool
