隐藏状态栏swift 4 [英] hide status bar swift 4

问题描述

我试图在我的一个UIViewControllers中隐藏状态栏(Swift 4).

I am trying to hide status bar in one of my UIViewControllers (Swift 4).

• 首先，我在Info.plist中将基于视图控制器的状态栏外观设置为 YES .

我在控制器中覆盖了prefersStatusBarHidden属性:

I overrode the prefersStatusBarHidden property in my controller:

override var prefersStatusBarHidden: Bool {
     return true
}

---

• 在viewDidLoad()中，我添加了setNeedsStatusBarAppearanceUpdate()函数以强制读取prefersStatusBarHidden属性.

---

• And in viewDidLoad(), I added setNeedsStatusBarAppearanceUpdate() function to force the prefersStatusBarHidden property to be read.

毕竟，我仍然在该UIViewController上看到状态栏.

After all that, I still see the status bar on that UIViewController.

有人可以帮我吗?

推荐答案

您可能已经找到了自己的解决方案，但是我以这种方式进行了工作:

You probably found your own solution to this already, but I got it working this way:

override func viewWillAppear(_ animated: Bool) {
    // Sets the status bar to hidden when the view has finished appearing
    let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
    statusBar.isHidden = true
}

override func viewWillDisappear(_ animated: Bool) {
    // Sets the status bar to visible when the view is about to disappear
    let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
    statusBar.isHidden = false
}
