ios - WKInterfaceButton 在 WatchKit 中的隐藏状态

Question

有没有办法查看WatchKit中WKInterfaceButton的当前隐藏状态？

Answer 1

看来你不能那样做。但是您可以使用状态存储自己的变量并使用它。

您可以在下面查看按钮父类的定义。

public class WKInterfaceObject : NSObject {

    public func setHidden(hidden: Bool)
    public func setAlpha(alpha: CGFloat)

    @available(watchOS 2.0, *)
    public func setHorizontalAlignment(horizontalAlignment: WKInterfaceObjectHorizontalAlignment)
    @available(watchOS 2.0, *)
    public func setVerticalAlignment(verticalAlignment: WKInterfaceObjectVerticalAlignment)

    public func setWidth(width: CGFloat)
    public func setHeight(height: CGFloat)
    @available(watchOS 2.0, *)
    public func setRelativeWidth(width: CGFloat, withAdjustment adjustment: CGFloat)
    @available(watchOS 2.0, *)
    public func setRelativeHeight(height: CGFloat, withAdjustment adjustment: CGFloat)

    @available(watchOS 2.0, *)
    public func sizeToFitWidth()
    @available(watchOS 2.0, *)
    public func sizeToFitHeight()

    public var interfaceProperty: String { get } // same as controller's property name
}
