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
我在这个问题上遇到了一些麻烦。我不太喜欢在视图中全局改变状态栏的颜色，然后在视图中改变它，然后像接受的答案一样消失。信不信由你，你可以通过在你想要的视图控制器上重写preferredStatusBarStyle来实现。经过很长一段时间，这是我所做的让它工作:
Change View controller-based status bar appearance in your info.plist to YES. Now any full screen view controller can change the status bar style by overriding preferredStatusBarStyle. I specify full screen because this will not work for (non-full screen) modal view controllers, not without setting modalPresentationCapturesStatusBarAppearance to Yes that is. Also if you have embedded view controllers, like in a navigation controller for example, it will ask the top most view controller for status bar style. Overriding childViewControllerForStatusBarStyle and passing the embedded view controller is supposed to work but it didn't for me. So I just returned the embedded view controllers preferred status bar as the preferred status bar style. Something like this: override var preferredStatusBarStyle: UIStatusBarStyle { if let topViewController = viewControllers.last { return topViewController.preferredStatusBarStyle } return .default }

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
}
Swift 4.2解决方案与NavigationController
第一步:
打开你的信息。并插入一个名为“View controller based status bar appearance”或UIViewControllerBasedStatusBarAppearance的新键到YES，让每个VC使用自己的状态属性。
第二步
在每个VC中，像这样重写preferredStatusBarStyle属性:
override var preferredStatusBarStyle : UIStatusBarStyle {
return .lightContent //.default for black style
}
最后一步
重写自定义NavigationController类中的preferredStatusBarStyle属性:
class NavigationController : UINavigationController {
override var preferredStatusBarStyle : UIStatusBarStyle {
if let topVC = viewControllers.last {
//return the status property of each VC, look at step 2
return topVC.preferredStatusBarStyle
}
return .default
}
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)
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
对我有用的是，在故事板中，转到导航控制器，选择导航栏，单击属性检查器，然后将默认样式改为黑色。就是这样!
