大佬教程收集整理的这篇文章主要介绍了xcode – Swift-设置可见菜单控制器，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
let MenuController: UIMenuController = UIMenuController.sharedMenuController() MenuController.menuVisible = true MenuController.arrowDirection = UIMenuControllerArrowDirection.Down MenuController.setTargetRect(CGRectMake(100,80,50,50),inView: self.view) let MenuItem_1: UIMenuItem = UIMenuItem(title: "Menu",action: "delete:") let MenuItems: NSArray = [delete] MenuController.menuItems = MenuItems
>在获得sharedMenuController之前调用becomeFirstResponder()
>最后@L_179_4@menu.setMenuVisible(true,animated：truE)
>覆盖canBecomeFirstResponder函数
>覆盖canPerformAction函数
>为选择器编写功能
这是一个例子
func someFunc() { becomeFirstResponder() var menu = UIMenuController.sharedMenuController() var deleteItem = UIMenuItem(title: "delete me",action: SELEctor("deleteLine")) menu.menuItems = [deleteItem] menu.setTargetRect(CGRectMake(100,inView: self) menu.setMenuVisible(true,animated: truE) } func deleteLine() { //Do something here } override func canBecomeFirstResponder() -> Bool { return true } override func canPerformAction(action: SELEctor,withSender sender: AnyObject?) -> Bool { // You need to only return true for the actions @R_673_8337@ant,otherwise you get the whole range of // iOS actions. You can see this by just removing the if statement here. if action == SELEctor("deleteLine") { return true } return false }
