我正试图在屏幕上获取触摸的坐标,以显示弹出菜单
如何在页面视图控制器中使用
我在这做错了什么？
override func touchesBegan(touches: Set<UITouch>,withEvent event: UIEvent?) {
if let touch = touches.first {
let position = touch.locationInView(view)
print(position)
}
}
解决方法
在PageViewController中,如果要弹出窗口
在viewDidLoad中：
let tap = UITapGestureRecognizer(target: self,action: "showMoreActions:")
tap.numberOfTapsrequired = 1
view.addGestureRecognizer(tap)
使页面视图控制器继承UIGestureRecognizerDelegate,然后添加：
func showMoreActions(touch: UITapGestureRecognizer) {
let touchPoint = touch.locationInView(self.view)
let DynamicView = UIView(frame: CGRectMake(touchPoint.x,touchPoint.y,100,100))
DynamicView.backgroundColor=UIColor.greenColor()
DynamicView.layer.cornerRadius=25
DynamicView.layer.borderWidth=2
self.view.addSubview(DynamicView)
}
