斯威夫特3

在信息。plist设置基于控制器的状态栏外观为NO

调用uiapplication。shared。isstatusbarhidden = true

这对我来说是个问题，因为iOS 9不支持上面提到的任何方法，比如UIApplication.sharedApplication()。statusBarHidden = true 或

UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.None)

and

override func prefersStatusBarHidden() -> Bool {
     return true
}

工作，但不提供可编程的解决方案，我可以改变的条件。 (statusBarHidden = true和statusBarHidden = false，就像我们之前做的那样)。

解决这种疯狂的方法:

通过添加prefersStatusBarHidden()像下面这样，你可以通过编程控制隐藏和显示状态栏，而不需要添加UIViewControllerBasedStatusBarAppearance设置到你的info.plist:

var showStatusBar = true

override func prefersStatusBarHidden() -> Bool {
     if showStatusBar {
         return false
     }
     return true
}

private func showStatusBar(enabled: Bool) {
    showStatusBar = enabled
    prefersStatusBarHidden()
}

然后在代码中像这样使用它:

//Hide Status Bar
showStatusBar(false)

OR

//Show Status Bar
showStatusBar(true)

我使用的是Xcode 8.1 (8B62)，部署目标设置为10.1，上面提到的覆盖选项我没有太多的运气。然而，检查部署信息中的“隐藏状态栏”选项对我来说是有用的。

我希望这能有所帮助。

一个对我有效的解决方案;如果你想在加载时隐藏特定视图控制器上的状态栏:

import UIKit

class ViewController: UIViewController {

private var hideStatusBar: Bool = false

override var prefersStatusBarHidden: Bool {
    return hideStatusBar
}

override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation {
    return UIStatusBarAnimation.slide
}

override func viewDidLoad() {
    super.viewDidLoad()

    view.backgroundcolor = .white
    hideStatusBar = true

    UIView.animate(withDuration: 0.3) {
        self.setNeedsStatusBarAppearanceUpdate()
    }
}

注意:如果你在你的信息中设置了“基于控制器的状态栏外观”为“NO”。请列出上面的代码不工作。你应该将键设置为“YES”或者从info.plist中删除它
