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
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()
}
}

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()
}

点击支持文件组(左边顶部-项目名称)。单击“信息”。点击列表之间的+，就像下面的bundle name。并添加“基于视图控制器的状态栏外观”并将其设置为NO。 然后打开AppDelegate.swift，像这样修改:
func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)
return true
}
这是它。
另一种非常简单的方法是创建UINavigationController类的扩展。
因为重写preferredStatusBarStyle:方法不会工作，除非我们在UINavigationController类内部做它。
extension UINavigationController {
open override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
}
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
}
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 }
