Ios 双面视图不工作
我有一个子类Ios 双面视图不工作,ios,uiview,catransform3d,catransformlayer,Ios,Uiview,Catransform3d,Catransformlayer,我有一个子类UIView名为TitleView,这个子类所做的就是覆盖layerClass以返回catTransferMLayer 我的标题视图属性有一些子视图;标题背景视图和标题标签 运行代码时,标题视图的顶层可见(绿色背景),但运行翻转动画时,没有动画。代码只是跳转到结束状态。此外,没有可见的底层(红色背景),只有标题视图的反转版本(转换后的标题标签) 在IBOutlet setter中,我有以下代码: @IBOutlet private weak var titleView: TitleV

我的标题视图
属性有一些子视图;标题背景视图
和标题标签
运行代码时,标题视图的顶层可见(绿色背景),但运行翻转动画时,没有动画。代码只是跳转到结束状态。此外,没有可见的底层(红色背景),只有标题视图的反转版本(转换后的标题标签)
在IBOutlet setter中,我有以下代码:
@IBOutlet private weak var titleView: TitleView! {
didSet {
titleView.backgroundColor = UIColor.clearColor()
let topLayer = CALayer()
topLayer.backgroundColor = UIColor.greenColor().CGColor
topLayer.frame = titleView.bounds
topLayer.doubleSided = false
topLayer.zPosition = 3
titleView.layer.addSublayer(topLayer)
let bottomLayer = CALayer()
bottomLayer.backgroundColor = UIColor.redColor().CGColor
bottomLayer.frame = titleView.bounds
bottomLayer.doubleSided = false
bottomLayer.zPosition = 2
bottomLayer.transform = CATransform3DMakeRotation(CGFloat(M_PI), 1, 0, 0)
titleView.layer.addSublayer(bottomLayer)
}
}

更新:将标题EWBACKGROUNDVIEW
的背景色设置为清晰的颜色将显示红色的底层。但是仍然没有动画发生。此外,反转版本在不应该更新时显示反转的标题标签
