我在屏幕上创建了两个UIButton
,当按下按钮时,屏幕上会显示动画。但是,从不调用按钮的目标函数,因为我认为按钮没有被按下"。如果我只是在屏幕上创建按钮,按钮确实有效,所以我认为这个问题与从屏幕边界外部动画到屏幕上的按钮有关。
编辑:按钮会在屏幕上正确显示动画并且可见,但按下它们不会执行任何操作。
代码:
var isMenuOpen : Bool = false
var button_height : CGFloat = UIScreen.mainScreen().bounds.height/8
var button_view : UIView!
var mylists : UIButton!
var settings : UIButton!
@IBAction func openMenu(sender: AnyObject) {
UIView.animateWithDuration(0.6, delay: 0.0, options: .CurveEaseOut, animations: {
self.view.transform = CGAffineTransformMakeTranslation(0.0, self.button_height * (self.isMenuOpen ? 0 : -1))
}, completion: {finished in
self.isMenuOpen = !self.isMenuOpen
})
}
override func viewDidLoad() {
super.viewDidLoad()
initButtons()
}
func initButtons() {
button_view = UIView(frame: CGRect(x:0.0, y:UIScreen.mainScreen().bounds.height, width:UIScreen.mainScreen().bounds.width, height:button_height))
button_view.userInteractionEnabled = true
mylists = UIButton(frame: CGRect(x:0.0, y:0.0, width:UIScreen.mainScreen().bounds.width/2.0, height:button_height))
mylists.setTitle("My Lists", forState: .Normal)
mylists.backgroundColor = UIColor(red: 255/255, green: 105/255, blue: 180/255, alpha: 1.0)
mylists.addTarget(self, action: #selector(showLists(_:)), forControlEvents: .TouchUpInside)
button_view.addSubview(mylists)
settings = UIButton(frame: CGRect(x:UIScreen.mainScreen().bounds.width/2.0, y:0.0, width:UIScreen.mainScreen().bounds.width/2.0, height:button_height))
settings.setTitle("Settings", forState: .Normal)
settings.backgroundColor = UIColor(red: 135/255, green: 205/255, blue: 236/255, alpha: 1.0)
settings.addTarget(self, action: #selector(showSettings(_:)), forControlEvents: .TouchUpInside)
button_view.addSubview(settings)
self.view.addSubview(button_view)
}
func showLists(sender: UIButton!) {
print("showLists")
}
func showSettings(sender: UIButton!) {
print("showSettings")
}
感谢任何帮助。谢谢!

我没有确切过渡的目标,但看起来按住button_view
按钮的视图永远不会转移到屏幕上。
您是要尝试让每个按钮进入屏幕,还是试图让两个按钮都进入容器内的屏幕(button_view_
)?如果你想两者兼顾,我建议你做
UIView.animateWithDuration(0.6, delay: 0.0, options: .CurveEaseOut, animations: {
self.button_view.transform = CGAffineTransformMakeTranslation(0.0, -1*(UIScreen.mainScreen().bounds.height))
}, completion: {finished in
self.isMenuOpen = !self.isMenuOpen
})
这是基于您尝试将整个框移动到整个屏幕的假设。
编辑:
啊!我看到发生了什么!所以你正在移动self.view,你永远不想移动UIViewController.view。移动视图的容器。因此,不要移动self.view,而是移动button_view。移动UIController.view会删除UIViewController的所有下层和功能
