swift - 如何使工具栏附加到底部 iOS Swift

Question

我有一个标签栏和导航栏的问题。有一个工具栏我需要显示在标签栏的顶部，但附在最底部。

现在我得到这个:

我的代码是:

  private func showToolBar() {
    tabBarController?.tabBar.isHidden = true
    navigationController?.setToolbarHidden(false, animated: true)

    let archiveButton = UIBarButtonItem(image: #imageLiteral(resourceName: "deactivateIcons"), style: .plain, target: self, action: #selector(archive))
    let flexibleSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: self, action: nil)
    let refreshButton = UIBarButtonItem(image: #imageLiteral(resourceName: "changeStatusIcons"), style: .plain, target: self, action: #selector(refresh))
    archiveButton.tintColor = Colors.Purple
    refreshButton.tintColor = Colors.Purple

    setToolbarItems([archiveButton, flexibleSpace, refreshButton], animated: true)

    navigationController?.toolbar.setShadowImage(UIImage(), forToolbarPosition: .bottom)

}

所以工具栏恰好出现在标签栏的顶部。如何解决这个问题？提前致谢!

试试这个:

将该代码放在 showToolBar() 函数的最后一行

让 screenSize: CGRect = UIScreen.main.bounds
navigationController?.toolbar.frame = CGRect(x: 0, y: screenSize.height - tabBarHeight - 50, width: screenSize.width, height: 50)
