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?

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!

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()
    }

}

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()
    }

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
