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
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
}
其他回答
我已经设置了特定的颜色(在RGB格式)使用下面的代码在应用程序委托文件:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
. . .
UIApplication.sharedApplication().statusBarHidden = false
UIApplication.sharedApplication().statusBarStyle = .LightContent
let statusBar: UIView = UIApplication.sharedApplication().valueForKey("statusBar") as! UIView
if statusBar.respondsToSelector(Selector("setBackgroundColor:")) {
statusBar.backgroundColor = UIColor.init(red: 0.1, green: 0.27, blue: 0.60, alpha: 1.0)
}
. . .
}
您还需要添加以下关键信息。Plist文件:
查看基于控制器的状态栏外观，布尔值设置为NO
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
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。
适用于基于导航的应用
var addStatusBar = UIView()
addStatusBar.frame = CGRectMake(0, 0, UIScreen.mainScreen().bounds.width, 20);
addStatusBar.backgroundColor = global().UIColorFromRGB(0x65b4d9)
self.window?.rootViewController?.view .addSubview(addStatusBar)
斯威夫特2
通过在viewWillAppear中添加以下内容，我成功地改变了状态栏背景的外观:
let statusBar: UIView = UIApplication.sharedApplication().valueForKey("statusBar") as! UIView
if statusBar.respondsToSelector(Selector("setBackgroundColor:")) {
statusBar.backgroundColor = .redColor()
}
