我正在UITapGesture
处理UITableView
并在所选UIMenuController
上显示UITableViewCell
。当我选择并出现菜单时,如果我将手指移到单元格上,看起来它的菜单似乎不断出现,我不喜欢它看起来如何。
有一些方法可以避免这种情况吗?
谢谢!
点按手势代码(Swift 2.3):
let longPressGesture:UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress))
longPressGesture.minimumPressDuration = 0.5
longPressGesture.delegate = self
self.messagesTableView.addGestureRecognizer(longPressGesture)
答案 0 :(得分:0)
好吧我终于解决了这个问题:
Swift 2
声明此全局变量
var menuControllerOpened:Bool = false
在tagGestureHandler上创建一个块:
func handleLongPress(longPressGesture:UILongPressGestureRecognizer) {
if !self.menuControllerOpened {
let p = longPressGesture.locationInView(self.messagesTableView)
self.selectedIndexPathMenu = self.messagesTableView.indexPathForRowAtPoint(p)
if self.selectedIndexPathMenu != nil {
//Do something you want
let menu = UIMenuController.sharedMenuController()
let reportItem = UIMenuItem(title: "Reportar usuario", action: #selector(reportMessageItem))
menu.menuItems = [reportItem]
menu.setTargetRect(cell.frame, inView: self.messagesTableView)
menu.setMenuVisible(true, animated: true)
}
}
}
但是配置一些通知事件,它们将在显示或隐藏MenuController时处理:
func configureMenuControllerEvents() {
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(handleMenuControllerShow), name: UIMenuControllerWillShowMenuNotification, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(handleMenuControllerHide), name: UIMenuControllerWillHideMenuNotification, object: nil)
}
func handleMenuControllerShow() {
self.menuControllerOpened = true
}
func handleMenuControllerHide() {
self.menuControllerOpened = false
}
