在iOS 9中不推荐使用setStatusBarHidden（_：withAnimation :) [英] setStatusBarHidden(_:withAnimation:) deprecated in iOS 9

问题描述

我在iOS 9中看到 setStatusBarHidden（_：withAnimation：）现已弃用，文档说使用 [UIViewController prefersStatusBarHidden] 相反，但如果我还想用幻灯片动画隐藏状态栏，iOS 9中的替代方案是什么？

I see that in iOS 9 setStatusBarHidden(_:withAnimation:) is now deprecated and the documentation says to use [UIViewController prefersStatusBarHidden] instead but what is the alternative in iOS 9 if I still want to hide the status bar with a slide animation?

推荐答案

参考 preferredStatusBarUpdateAnimation ，

代码

class ViewController: UIViewController {
    var isHidden:Bool = false{
        didSet{
            UIView.animate(withDuration: 0.5) { () -> Void in
                self.setNeedsStatusBarAppearanceUpdate()
            }  
         }
    }
    @IBAction func clicked(sender: AnyObject) {
        isHidden = !isHidden
    }
    override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation{
        return .slide
    }
    override var prefersStatusBarHidden: Bool{
        return isHidden
    }
 }
