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
在Swift 4或4.2中
你可以加上vc
preferredStatusBarStyle
并设置返回值为
.lightContent或.default
ex:
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
其他回答
请在“didFinishLaunchingWithOptions launchOptions:”Appdelegate类中使用此代码
UIApplication.shared.statusBarStyle = .lightContent let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView if statusBar.responds(to: #selector(setter: UIView.backgroundColor)){ statusBar.backgroundColor = UIColor.black }
iOS 13
var statusBarView: UIView = UIView()
if #available(iOS 13.0, *) {
let tag:UInt64 = 38482458385
if let statusBar = UIApplication.shared.keyWindow?.viewWithTag(Int(tag)) {
statusBar.backgroundColor = UIColor.red
statusBarView = statusBar
} else {
let statusBar = UIView(frame: UIApplication.shared.statusBarFrame)
statusBar.tag = Int(tag)
UIApplication.shared.keyWindow?.addSubview(statusBar)
statusBarView = statusBar
}
} else {
statusBarView = (UIApplication.shared.value(forKey: "statusBar") as? UIView)!
if statusBarView.responds(to: #selector(setter: UIView.backgroundColor)){
statusBarView.backgroundColor = UIColor.red
}
}
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
}
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()
}
}
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
Swift 3.0升级
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.statusBarStyle = .lightContent
return true
}
