ios - 如何在 iOS 7 上更改状态栏背景颜色和文本颜色？

Question

我当前的应用程序在 iOS 5 和 6 上运行。

导航栏为橙色，状态栏为黑色背景颜色和白色文本颜色。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，与导航栏具有相同的橙色背景色，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。

如何使状态栏看起来与 iOS 5 和 6 中的一样，即黑色背景颜色和白色文本颜色？如何以编程方式执行此操作？

我不得不尝试寻找其他方法。不涉及addSubview窗口。因为当键盘出现时我正在向上移动窗口。

Objective-C

- (void)setStatusBarBackgroundColor:(UIColor *)color {

    UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];

    if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
        statusBar.backgroundColor = color;
    }
}

迅速

func setStatusBarBackgroundColor(color: UIColor) {

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

    statusBar.backgroundColor = color
}

func setStatusBarBackgroundColor(color: UIColor) {

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

    statusBar.backgroundColor = color
}

调用此表格application:didFinishLaunchingWithOptions对我有用。

注意我们在应用商店中有一个具有这种逻辑的应用。所以我想应用商店政策没问题。

转到您的应用程序info.plist

1) 设置View controller-based status bar appearance为NO
2) 设置Status bar style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];
}

在iOS 7中处理状态栏的背景颜色时，有2种情况

案例一：使用导航栏查看

在这种情况下，在您的 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，在您的 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];

1) 在 plist 中将 UIViewControllerBasedStatusBarAppearance 设置为 YES

2）在 viewDidLoad 做一个[self setNeedsStatusBarAppearanceUpdate];

3）添加以下方法：

您可以在应用程序启动期间或视图控制器的 viewDidLoad 期间设置状态栏的背景颜色。

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
    }

}

这是结果：

在 viewDidLoad 添加函数 -setNeedsStatusBarAppearanceUpdate
覆盖视图控制器中的 preferredStatusBarStyle。

在 iOS 7 中，状态栏没有背景，因此如果您在其后面放置一个 20 像素高的黑色视图，您将获得与 iOS 6 相同的结果。

此外，您可能需要阅读iOS 7 UI 转换指南以获取有关该主题的更多信息。

在你的 ViewDidLoad 方法中写下这个：

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

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”是一个 UINavigationBar。

如果您使用的是UINavigationController，则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setNavigationBarBackground导航控制器的方法来设置导航栏背景颜色和状态栏。

请记住，setNavigationBar(hidden: Bool, animated: Bool)当您想要隐藏导航栏时，您必须使用扩展中的方法，否则用作背景的视图仍然可见。
