ios - 如何在 UITabBarController 中的所有选项卡上制作 UIView
<p><p>在 uitabbarController 的所有选项卡之上制作 uiview。
<a href="/image/BtDVG.png" rel="noreferrer noopener nofollow"><img src="/image/BtDVG.png" alt="enter image description here"/></a>我计划制作一个名为“uiView.swift”的baseviewcontroller。在“uiView.swift”中，我添加了我的uiview。之后，我想从该 uiView.swift 继承每个选项卡 ViewController(比如“resturent.swift”)。因此，在 UITabBarController 的每个选项卡中，您将看到“uiView.swift” Viewresued.uiView.swift 连接到 Storyboard 中的 ViewController，该按钮具有在按钮单击时显示 View 的按钮。这是我的“uiView.swift”</p >
<pre><code>class uiView: UIViewController {
var menuView: UIView?
override func viewDidLoad() {
super.viewDidLoad()
menuView = UIView(frame: CGRect(x: 0, y: -200, width: 420, height: 200))
menuView?.backgroundColor = UIColor.green
view.addSubview(menuView!)
}
@objc func MyBag(){
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
@IBAction func collectionmenuone(_ sender: Any) {
menuView=UIView(frame: CGRect(x: 0, y: 0, width: 420, height: 200))
menuView?.backgroundColor=UIColor.lightGray
self.view.addSubview(menuView!)
var btnbag = UIButton(type: .roundedRect)
btnbag.addTarget(self, action: #selector(self.MyBag), for: .touchUpInside)
btnbag.frame = CGRect(x: 104, y:130 , width: 150, height: 60)
btnbag.setTitle("Done", for: .normal)
btnbag.backgroundColor=UIColor.green
menuView?.addSubview(btnbag)
}
}

<p>uiView.swift 是 UIViewController 类型，resturent.swif 是 UICollectionViewController 类型。您可以将应用程序的入口点从 uiView.swift 更改为登录 ViewController (Viewcontroller.swift)以运行应用程序。我如何通过继承重用uiView.swift 中的 View ？您可以从此链接下载项目。 <a href="https://drive.google.com/file/d/1XSwOZcfvglB_7Zt_E8W8W3Dym3i1_lrB/view?usp=sharing" rel="noreferrer noopener nofollow">https://drive.google.com/file/d/1XSwOZcfvglB_7Zt_E8W8W3Dym3i1_lrB/view?usp=sharing</a> </p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您不应在任何 View 上添加菜单 View 。取而代之的是，您可以直接从 AppDelegate 将其添加到您的窗口中。
在窗口上添加 View 会将其置于当前可见的所有 View 之上。</p></p>
