推荐答案

你无法获取任何 WKInterface UI 元素的状态，比如按钮 (WKInterfaceButton) 标签 (WKInterfaceLabel) 等.我认为这是 Apple 设计的这样，因为它涉及在您的 iOS 设备上运行的扩展程序之间的底层通信手表应用程序.为了节省这种开销，没有 getter，并且扩展应该跟踪状态变化(它是可以改变状态的那个).

You can't get the state of any WKInterface UI element like buttons (WKInterfaceButton) label (WKInterfaceLabel) etc. I think this is designed by Apple like this because it involve under the hood communication between the extension running on your iOS device & the watch App. To save this overhead there are no getters and the extension should keep track of the state change (it is the one that can change the state).
