我目前的应用程序在iOS 5和6上运行 .

导航栏为橙色，状态栏为黑色背景颜色，白色为文本颜色 . 但是，当我在iOS 7上运行相同的应用程序时，我发现状态栏看起来是透明的，具有与导航栏相同的橙色背景颜色，状态栏文本颜色为黑色 .

由于这个原因，我无法区分状态栏和导航栏 .

如何使状态栏看起来与iOS 5和6中的状态相同，即黑色背景颜色和白色文本颜色？我该如何以编程方式执行此操作？

func setStatusBarBackgroundColor(color: UIColor) {

    guard  let statusBar = UIApplication.sharedApplication().valueForKey("statusBarWindow")?.valueForKey("statusBar") as? UIView else {

    statusBar.backgroundColor = color
}

斯威夫特3

func setStatusBarBackgroundColor(color: UIColor) {

    guard let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView else { return }

    statusBar.backgroundColor = color
}

拨打此表单 application:didFinishLaunchingWithOptions 为我工作 .

注：我们在应用程序商店中有一个具有此逻辑的应用程序 . 所以我想应用商店政策是可以的 .

转到你的应用 info.plist

1）将 View controller-based status bar appearance 设为 NO
2）将 Status bar style 设为 UIStatusBarStyleLightContent

然后转到您的应用程序委托并将以下代码粘贴到您设置Windows的RootViewController的位置 .

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
    UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.width, 20)];
    view.backgroundColor=[UIColor blackColor];
    [self.window.rootViewController.view addSubview:view];
}

希望能帮助到你 .

1）在plist中将UIViewControllerBasedStatusBarAppearance设置为YES

2）在viewDidLoad中做 [self setNeedsStatusBarAppearanceUpdate];

3）添加以下方法：
```
-(UIStatusBarStyle)preferredStatusBarStyle{ 
    return UIStatusBarStyleLightContent; 
 }
```

在iOS 7中处理状态栏的背景颜色时，有两种情况

案例1：使用导航栏查看

在这种情况下，请在viewDidLoad方法中使用以下代码

UIApplication *app = [UIApplication sharedApplication];
 CGFloat statusBarHeight = app.statusBarFrame.size.height;

 UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, -statusBarHeight, [UIScreen mainScreen].bounds.size.width, statusBarHeight)];
 statusBarView.backgroundColor = [UIColor yellowColor];
 [self.navigationController.navigationBar addSubview:statusBarView];

案例2：没有导航栏的视图

在这种情况下，请在viewDidLoad方法中使用以下代码

UIApplication *app = [UIApplication sharedApplication];
 CGFloat statusBarHeight = app.statusBarFrame.size.height;

 UIView *statusBarView =  [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, statusBarHeight)];
 statusBarView.backgroundColor  =  [UIColor yellowColor];
 [self.view addSubview:statusBarView];

在iOS 7中，状态栏没有背景，因此如果您在其后面放置一个黑色的20px高视图，您将获得与iOS 6相同的结果 .

另外，您可能需要阅读iOS 7 UI Transition Guide以获取有关该主题的更多信息 .

您可以在应用程序启动期间或视图控制器的viewDidLoad期间为状态栏设置背景颜色 .

extension UIApplication {

    var statusBarView: UIView? {
        return value(forKey: "statusBar") as? UIView
    }

}

// Set upon application launch, if you've application based status bar
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
        return true
    }
}


or 
// Set it from your view controller if you've view controller based statusbar
class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
    }

}

结果如下：

enter image description here

这是关于状态栏更改的Apple Guidelines/Instruction . 状态栏中只允许黑暗和浅色（黑色和黑色） .

这是 - 如何更改状态栏样式：

如果要设置状态栏样式，应用程序级别，然后在.plist'文件中将UIViewControllerBasedStatusBarAppearance设置为NO` .

如果您要设置状态栏样式，请在视图控制器级别，然后按照下列步骤操作：

如果只需要在UIViewController级别设置状态栏样式，请在 .plist 文件中将 UIViewControllerBasedStatusBarAppearance 设置为 YES .
在viewDidLoad中添加功能 - setNeedsStatusBarAppearanceUpdate
覆盖视图控制器中的preferredStatusBarStyle .

override func viewDidLoad() {
    super.viewDidLoad()
    self.setNeedsStatusBarAppearanceUpdate()
}

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

在ViewDidLoad方法中写下这个：

if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {
    self.edgesForExtendedLayout=UIRectEdgeNone;
    self.extendedLayoutIncludesOpaqueBars=NO;
    self.automaticallyAdjustsScrollViewInsets=NO;
}

它在一定程度上修复了我和其他UI错位的状态栏颜色 .

只是为了添加Shahid的答案 - 您可以使用此方法考虑方向更改或不同的设备（iOS7）：

{
  ...

  //Create the background
  UIView* statusBg = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.window.frame.size.width, 20)];
  statusBg.backgroundColor = [UIColor colorWithWhite:1 alpha:.7];

  //Add the view behind the status bar
  [self.window.rootViewController.view addSubview:statusBg];

  //set the constraints to auto-resize
  statusBg.translatesAutoresizingMaskIntoConstraints = NO;
  [statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeTop multiplier:1.0 constant:0.0]];
  [statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeLeft multiplier:1.0 constant:0.0]];
  [statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeRight multiplier:1.0 constant:0.0]];
  [statusBg.superview addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[statusBg(==20)]" options:0 metrics:nil views:NSDictionaryOfVariableBindings(statusBg)]];

对于背景，您可以轻松添加视图，例如：

UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 20)];
    view.backgroundColor=[UIColor colorWithRed:0/255.0 green:0/255.0 blue:0/255.0 alpha:0.1];
    [navbar addSubview:view];

其中“navbar”是UINavigationBar .

iTroid23解决方案适合我 . 我错过了Swift解决方案 . 所以这可能有用：

1）在我的plist中，我不得不添加：
```
<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>
```
2）我不需要调用“setNeedsStatusBarAppearanceUpdate” .

3）在swift中我必须将它添加到我的UIViewController中：
```
override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return UIStatusBarStyle.LightContent
}

如果你使用的是 UINavigationController ，你可以使用这样的扩展名：

extension UINavigationController {
    private struct AssociatedKeys {
        static var navigationBarBackgroundViewName = "NavigationBarBackground"
    }

    var navigationBarBackgroundView: UIView? {
        get {
            return objc_getAssociatedObject(self,
                                        &AssociatedKeys.navigationBarBackgroundViewName) as? UIView
        }
        set(newValue) {
             objc_setAssociatedObject(self,
                                 &AssociatedKeys.navigationBarBackgroundViewName,
                                 newValue,
                                 .OBJC_ASSOCIATION_RETAIN)
        }
    }

    func setNavigationBar(hidden isHidden: Bool, animated: Bool = false) {
       if animated {
           UIView.animate(withDuration: 0.3) {
               self.navigationBarBackgroundView?.isHidden = isHidden
           }
       } else {
           navigationBarBackgroundView?.isHidden = isHidden
       }
    }

    func setNavigationBarBackground(color: UIColor, includingStatusBar: Bool = true, animated: Bool = false) {
        navigationBarBackgroundView?.backgroundColor = UIColor.clear
        navigationBar.backgroundColor = UIColor.clear
        navigationBar.barTintColor = UIColor.clear

        let setupOperation = {
            if includingStatusBar {
                self.navigationBarBackgroundView?.isHidden = false
                if self.navigationBarBackgroundView == nil {
                    self.setupBackgroundView()
                }
                self.navigationBarBackgroundView?.backgroundColor = color
            } else {
                self.navigationBarBackgroundView?.isHidden = true
                self.navigationBar.backgroundColor = color
            }
        }

        if animated {
            UIView.animate(withDuration: 0.3) {
                setupOperation()
            }
        } else {
            setupOperation()
        }
    }

    private func setupBackgroundView() {
        var frame = navigationBar.frame
        frame.origin.y = 0
        frame.size.height = 64

        navigationBarBackgroundView = UIView(frame: frame)
        navigationBarBackgroundView?.translatesAutoresizingMaskIntoConstraints = true
        navigationBarBackgroundView?.autoresizingMask = [.flexibleWidth, .flexibleBottomMargin]

        navigationBarBackgroundView?.isUserInteractionEnabled = false

        view.insertSubview(navigationBarBackgroundView!, aboveSubview: navigationBar)
    }
}

它基本上使导航栏背景透明，并使用另一个UIView作为背景 . 您可以调用导航控制器的 setNavigationBarBackground 方法，将导航栏背景颜色与状态栏一起设置 .

请记住，如果要隐藏导航栏，则必须在扩展中使用 setNavigationBar(hidden: Bool, animated: Bool) 方法，否则用作背景的视图仍然可见 .

请试试这个 . 使用这段代码在你的appdelegate类“didFinishLaunchingWithOptions”函数中

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; [application setStatusBarHidden:NO]; UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"]; if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) { statusBar.backgroundColor = [UIColor blackColor]; }

我成功地自定义了StatusBar颜色非常简单，在方法中添加 AppDelegate.cs 文件：

public override bool FinishedLaunching(UIApplication app, NSDictionary options)

下一个代码：
```
UIView statusBar = UIApplication.SharedApplication.ValueForKey(new NSString("statusBar")) as UIView;

if (statusBar!=null && statusBar.RespondsToSelector(new Selector("setBackgroundColor:")))
{
   statusBar.BackgroundColor = Color.FromHex(RedColorHex).ToUIColor();
}
```
所以你得到这样的东西：
