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
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。

有两种情况:
1.显示导航栏
1)添加1uiviewcontrollerbasedstatusbarappearance /基于视图控制器的状态栏外观到你的信息。Plist, set value为true。
2)在你的自定义NavigationController类中覆盖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
}
3)覆盖preferredStatusBarStyle在你的特定视图控制器:
override var preferredStatusBarStyle : UIStatusBarStyle {
return .lightContent
}
2.隐藏导航栏
1)同上
2)不需要以上第二步，直接执行第三步。
override var preferredStatusBarStyle : UIStatusBarStyle {
return .lightContent
}
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
}

}
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
