UIBarItem

@_spi(FW) extension UIBarItem

  • 获取UIBarItem(UIBarButtonItem、UITabBarItem)内部的view，通常对于navigationItem和tabBarItem而言，需要在设置为item后并且在bar可见时(例如 viewDidAppear:及之后)获取fwView才有值

    Declaration

    Swift

    public weak var fw_view: UIView? { get }

  • 当item内的view生成后就会调用一次这个block，仅对UIBarButtonItem、UITabBarItem有效

    Declaration

    Swift

    public var fw_viewLoadedBlock: ((UIBarItem, UIView) -> Void)? { get set }
