如何在iOS 7上更改状态栏背景颜色和文本颜色？

我当前的应用程序运行在iOS 5和iOS 6上

导航栏的颜色为橙色，状态栏的背景颜色为黑色，文本颜色为白色。但是，当我在iOS 7上运行相同的应用程序时，我观察到状态栏看起来是透明的，与导航栏的背景颜色相同，并且状态栏文本颜色为黑色

因此，我无法区分状态栏和导航栏

---

如何使状态栏与iOS 5和iOS 6中的状态栏相同，即黑色背景色和白色文本色？如何通过编程实现这一点？

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

此外，您可能需要阅读以了解有关主题的更多信息。

1）在plist中将UIViewControllerBasedStatusBarAppearance设置为YES

2） 在viewDidLoad中执行

[self-setNeedsStatusBarAppearanceUpdate]

3） 添加以下方法：

 -(UIStatusBarStyle)preferredStatusBarStyle{ 
    return UIStatusBarStyleLightContent; 
 } 

更新：

还要检查条形图颜色：为条形图提供自定义背景图像

对于文本颜色：使用
中的信息在ViewDidLoad方法中写入：

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的状态栏颜色和其他UI错误位置。
对于背景，您可以轻松添加视图，如示例所示：

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“导航栏”是UINavigationBar。
转到应用程序
info.plist



1） 将
查看基于控制器的状态栏外观
设置为
否


2） 将
状态栏样式设置为
UIStatusBarStyleLightContent



然后转到应用程序代理并将以下代码粘贴到设置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];
}

希望能有所帮助。
只需补充Shahid的答案-您可以使用以下（iOS7+）说明方向变化或不同的设备：

在iOS 7中处理状态栏的背景色时，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];

 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];

案例2：不带导航栏的视图

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, -statusBarHeight, [UIScreen mainScreen].bounds.size.width, statusBarHeight)];
 statusBarView.backgroundColor = [UIColor yellowColor];
 [self.navigationController.navigationBar addSubview:statusBarView];

 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];

斯威夫特：

对于iOS 9上的swift 2.0

将以下内容放置在应用程序代理中的didFinishLaunchingWithOptions下：

    let view: UIView = UIView.init(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.size.width, 20))

    view.backgroundColor = UIColor.blackColor()  //The colour you want to set

    view.alpha = 0.1   //This and the line above is set like this just if you want 
                          the status bar a darker shade of 
                          the colour you already have behind it.

    self.window!.rootViewController!.view.addSubview(view)

这个解决方案对我有效。我错过了快速解决方案。因此，这可能会有所帮助：

1） 在我的列表中，我必须添加以下内容：

<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>

警告：它不再适用于iOS 13和Xcode 11。

我不得不试着寻找其他的方法。它不涉及窗口上的
addSubview
。因为当键盘出现时，我正在向上移动窗口

UINavigationController
，则可以使用如下扩展：

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)

       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
方法来设置导航栏背景颜色和状态栏

请记住，然后必须使用
setNavigationBar（隐藏：Bool，动画：Bool）
方法，否则用作背景的视图仍将可见。
您可以在应用程序启动或视图控制器加载期间为状态栏设置背景色

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：




这是关于状态栏的更改。状态栏中只允许黑暗和光明（而黑色和黑色）

以下是-如何更改状态栏样式：

如果要设置状态栏样式，请在应用程序级别将“.plist”文件中的
UIViewControllerBasedStatusBarAppearance
设置为
NO

如果要在视图控制器级别设置状态栏样式，请执行以下步骤：

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添加函数中-
SetNeedssStatusBarAppearanceUpdate

覆盖视图控制器中的preferredStatusBarStyle

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
    }

}

-

试试这个。
在appdelegate类中使用此代码
didFinishLaunchingWithOptions
函数：

[[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，在方法中添加了
AppDelegate.cs
文件：

public override bool FinishedLaunching（UIApplication应用程序、NSDictionary选项）

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();
}

你会得到这样的结果：

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)
        }
    }

       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 {
