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?

Swift 3.0升级
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.statusBarStyle = .lightContent
return true
}
在Swift 5或xcode 11及以后的版本中设置(查看基于控制器的状态栏外观)key In info。plist为NO 然后转到项目目标，选择通用，设置状态栏样式为深色或浅色
实现preferredStatusBarStyle，如你所述，并调用self.setNeedsStatusBarAppearanceUpdate()在ViewDidLoad和 也在信息。设置UIViewControllerBasedStatusBarAppearance为YES(默认是YES)
目前还不清楚为什么它不起作用。我需要检查代码。另一个建议是 使用viewDidLoad UIApplication.sharedApplication()中的工作代码。statusBarStyle = . lightcontent，并将此更改为默认值，当您查看viewgetdisappear viewWillDisappear。
请在“didFinishLaunchingWithOptions launchOptions:”Appdelegate类中使用此代码
UIApplication.shared.statusBarStyle = .lightContent let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView if statusBar.responds(to: #selector(setter: UIView.backgroundColor)){ statusBar.backgroundColor = UIColor.black }
iOS 13
var statusBarView: UIView = UIView()
if #available(iOS 13.0, *) {
let tag:UInt64 = 38482458385
if let statusBar = UIApplication.shared.keyWindow?.viewWithTag(Int(tag)) {
statusBar.backgroundColor = UIColor.red
statusBarView = statusBar
} else {
let statusBar = UIView(frame: UIApplication.shared.statusBarFrame)
statusBar.tag = Int(tag)
UIApplication.shared.keyWindow?.addSubview(statusBar)
statusBarView = statusBar
}
} else {
statusBarView = (UIApplication.shared.value(forKey: "statusBar") as? UIView)!
if statusBarView.responds(to: #selector(setter: UIView.backgroundColor)){
statusBarView.backgroundColor = UIColor.red
}
}
override func viewWillAppear(animated: Bool) {
self.navigationController?.navigationBarHidden = true
UIApplication.sharedApplication().statusBarHidden = false
UIApplication.sharedApplication().statusBarStyle = .LightContent
let statusBar: UIView = UIApplication.sharedApplication().valueForKey("statusBar") as! UIView
if statusBar.respondsToSelector("setBackgroundColor:") {
statusBar.backgroundColor = UIColor.redColor()
}
}
