问题描述
我有两个带有图像的按钮，我想将一个按钮重叠在另一个按钮上. iOS Watch甚至可以做到吗?而且，如何像常规iOS编程一样在手表编程中处理sendViewtoBackground或BringSubViewtoFront等WKInterfaceObject的背景或前景深度?
I have two button with images and i want to overlap one over another. Is it even possible to do it iOS Watch?Moreover, how to handle background or foreground depth of a WKInterfaceObject in watch programming, like sendViewtoBackground or bringSubViewtoFront, as in normal iOS programming ?
推荐答案
在手表中，您没有Z层次结构.
In the watch you don't have a Z hierarchy.
您最多可以使用一个有背景的组，然后对该背景进行控制.
The max you can do is using a group, that has a background and then have controls over that background.
另一种替代方法(hack?)是将所有层次结构呈现到UIImage中，并在手表中进行设置.
Another alternative (hack?) is to render all your hierarchy into an UIImage and set it in the watch.
