我正在写一个日历视图，我在它的超级视图中添加了其他三个视图，所以日历视图应该在顶层，在模拟器上看起来很好
但是后来发现不能点击按钮，然后查看view层级，发现其他三个view在日历上重叠了，太诡异了，模拟器上的3d预览和view不一样
这是UI部分的代码
函数更新UI（）{
if calendarView != nil {
self.view.addSubview(calendarView!)
self.calendarView!.frame.origin = calendarViewPosition!
self.calendarView!.layer.zPosition = 5
self.calendarView!.layer.cornerRadius = self.setting.itemCardCornerRadius
self.calendarView!.layer.masksToBounds = true
self.calendarView!.setViewShadow()
UIView.animate(withDuration: 0.8, delay: 0, options: .curveEaseOut, animations: {
self.calendarView!.frame.origin.y += 50
}) { _ in
var newCalendarPageCordiateYDifference: CGFloat = 10
var newCalendarPageSizeDifference: CGFloat = 20
var zPosition: CGFloat = 4
for _ in 1 ... 3 {
let newCalendarPage = UIView()
newCalendarPage.frame = CGRect(x: self.calendarView!.frame.origin.x + newCalendarPageSizeDifference / 2, y: self.calendarView!.frame.origin.y, width: self.calendarView!.frame.width - newCalendarPageSizeDifference, height: self.calendarView!.frame.height - newCalendarPageSizeDifference)
newCalendarPage.backgroundColor = .white
newCalendarPage.layer.zPosition = zPosition
newCalendarPage.layer.cornerRadius = self.setting.itemCardCornerRadius
newCalendarPage.setViewShadow()
self.view.addSubview(newCalendarPage)
UIView.animate(withDuration: 0.3, delay: 0, options: .curveEaseOut, animations: {
newCalendarPage.frame.origin.y -= newCalendarPageCordiateYDifference
})
zPosition -= 1
newCalendarPageCordiateYDifference += 10
newCalendarPageSizeDifference += 50
}
}
}
}
