override func preferredStatusBarStyle() -> UIStatusBarStyle {
return UIStatusBarStyle.LightContent;
}
使用上述代码在任何ViewController中为特定的ViewController设置状态栏颜色为白色，在iOS8中对我来说是行不通的。有什么建议吗?使用UIApplication。shared应用方法，在信息中需要更改后颜色更改。Plist为整个应用程序。
// Change the colour of status bar from black to white
UIApplication.sharedApplication().statusBarStyle = .LightContent
我怎么能改变一些必要的和特定的视图控制器的状态栏颜色?

对于swift 3
.plist
View controller-based status bar appearance = NO
AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Custom statubar
UIApplication.shared.isStatusBarHidden = false
UIApplication.shared.statusBarStyle = .lightContent
let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
statusBar.backgroundColor = UIColor.gray
return true
}

在你的信息。plist你需要将基于视图控制器的状态栏外观定义为任何值。
如果你定义它为YES，那么你应该在每个视图控制器中重写preferredStatusBarStyle函数。
如果你定义它为NO，那么你可以在AppDelegate中使用
UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)
适用于swift4中基于特定视图控制器的导航
let app = UIApplication.shared
let statusBarHeight: CGFloat = app.statusBarFrame.size.height
let statusbarView = UIView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: statusBarHeight))
statusbarView.backgroundColor = UIColor.red
view.addSubview(statusbarView)
自定义状态栏颜色(iOS11+， Swift4+)
如果您正在寻找如何将状态栏更改为自定义颜色的解决方案，这是可行的解决方案。
let statusBarView = UIView()
view.addSubview(statusBarView)
statusBarView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
statusBarView.topAnchor.constraint(equalTo: view.topAnchor),
statusBarView.leftAnchor.constraint(equalTo: view.leftAnchor),
statusBarView.rightAnchor.constraint(equalTo: view.rightAnchor),
statusBarView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor)
])
statusBarView.backgroundColor = .blue
