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?
当前回答
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)
其他回答
对于没有嵌入navigationViewController的特定ViewController，只需将其添加到ViewController文件中。
override var preferredStatusBarStyle : UIStatusBarStyle {
return .lightContent
}
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。
在Swift 3.0 Xcode 8中，一切都要简单得多
使用下面的代码在应用程序委托文件，之后
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
插入:
UINavigationBar.appearance().barStyle = .black
UINavigationBar.appearance().barTintColor = UIColor(red: 230, green: 32, blue: 31, alpha: 1.0)
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
}
}
(截至2021年10月25日)
Swift 5, Swift 4.2, Swift 4
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
setNeedsStatusBarAppearanceUpdate()
}
override var preferredStatusBarStyle: UIStatusBarStyle {
.lightContent
}
