xcode 更改状态栏的颜色

Changing the Color of the Status Bar

提问by Tyler Rutt

I am trying to change the color of the status bar to like a blue, or some other color.

我正在尝试将状态栏的颜色更改为蓝色或其他颜色。

Is this possible, or does Apple not allow it?

这是可能的，还是苹果不允许？

NOTE: This solution fails under iOS 13 and later.

注意：此解决方案在 iOS 13 及更高版本下失败。

First in Plist set View controller-based status bar appearanceto NO

Plist 中的第一个设置View controller-based status bar appearance为NO

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
    if statusBar.responds(to:#selector(setter: UIView.backgroundColor)) {
        statusBar.backgroundColor = UIColor.blue
    }
    UIApplication.shared.statusBarStyle = .lightContent

    return true
}

The output screenshot is below

No, it's not possible with ready-made public APIs.

不，使用现成的公共 API 是不可能的。

But with the release of iOS 7, you're allowed to change the appearance of the status bar. Hence I am posting my workaround.

但是随着 的发布iOS 7，您可以更改状态栏的外观。因此，我发布了我的解决方法。

From an individual view controller by overriding the preferredStatusBarStyle:

通过覆盖从单个视图控制器preferredStatusBarStyle：

-(UIStatusBarStyle)preferredStatusBarStyle 
{ 
    return UIStatusBarStyleLightContent; 
}

Alternatively, you can set the status bar style by using the UIApplication statusBarStylemethod. To do this, insert a new key named “View controller-based status bar appearance” and set the value to NO.

或者，您可以使用UIApplication statusBarStyle方法设置状态栏样式。为此，请插入一个名为“基于视图控制器的状态栏外观”的新键，并将值设置为 NO。

By disabling the “View controller-based status bar appearance”, you can set the status bar style by using the following code.

通过禁用“基于视图控制器的状态栏外观”，您可以使用以下代码设置状态栏样式。

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

At the end, change the UINavigationBarproperty tint color like below

最后，更改UINavigationBar属性色调颜色，如下所示

[[UINavigationBar appearance] setBarTintColor:[UIColor blueColor]];

You can set background color for status bar during application launch or during viewDidLoad of your view controller.

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
    }

}

Here is result:

这是结果：

Here is Apple Guidelines/Instructionabout status bar change. Only Dark & light (while & black) are allowed in status bar.

这是有关状态栏更改的Apple 指南/说明。状态栏中只允许深色和浅色（同时和黑色）。

Here is - How to change status bar style:

这是 - 如何更改状态栏样式：

If you want to set status bar style, application level then set UIViewControllerBasedStatusBarAppearanceto NOin your `.plist' file.

如果你想设置状态栏样式，应用的水平，那么设置UIViewControllerBasedStatusBarAppearance到NO你的`的.plist”文件。

if you wan to set status bar style, at view controller level then follow these steps:

如果您想设置状态栏样式，请在视图控制器级别执行以下步骤：

1. Set the UIViewControllerBasedStatusBarAppearanceto YESin the .plistfile, if you need to set status bar style at UIViewController level only.

2. In the viewDidLoad add function - setNeedsStatusBarAppearanceUpdate

3. override preferredStatusBarStyle in your view controller.

1. 设置UIViewControllerBasedStatusBarAppearance到YES中.plist文件，如果需要设置状态栏样式仅UIViewController的水平。

2. 在 viewDidLoad 添加函数 - setNeedsStatusBarAppearanceUpdate

3. 覆盖视图控制器中的 preferredStatusBarStyle。

-

——

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

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

Set value of .plist according to status bar style setup level.

根据状态栏样式设置级别设置 .plist 的值。

Here is my workaround: create a UIView, add it to your root view of view controller as artificial status bar background
1.Create a UIView

这是我的解决方法：创建一个UIView，将其添加到视图控制器的根视图中作为人工状态栏背景 1.
创建一个UIView

// status bar's height is 20.0pt
CGRect frame = CGRectMake(0.0, 0.0, [UIScreen mainScreen].bounds.size.width, 20.0);
UIView *fakeStatusBarBG = [[UIView alloc] initWithFrame:frame];
fakeStatusBarBG.backgroundColor = [UIColor yourColor];

2.Add it to your view controller's root view

2.将其添加到您的视图控制器的根视图

// self is your view controller, make sure fakeStatusBarBG is the top subview in your view hierarchy
[self.view insertSubview:fakeStatusBarBG aboveSubview:yourTopSubview];

There your go.

你去吧。

3.(Additional)Change the content color on status bar, only white or black.

3.（附加）改变状态栏的内容颜色，只有白色或黑色。

- (UIStatusBarStyle)preferredStatusBarStyle
{
    if (youWantWhiteColor)
    {
        return UIStatusBarStyleLightContent;
    }
    return UIStatusBarStyleDefault;
}

This workaround does not use private API, so you're safe. :-)

此解决方法不使用私有 API，因此您很安全。:-)

I made this extension to change color of status bar

我做了这个扩展来改变状态栏的颜色

public extension UIViewController {
    func setStatusBar(color: UIColor) {
        let tag = 12321
        if let taggedView = self.view.viewWithTag(tag){
            taggedView.removeFromSuperview()
        }
        let overView = UIView()
        overView.frame = UIApplication.shared.statusBarFrame
        overView.backgroundColor = color
        overView.tag = tag
        self.view.addSubview(overView)
    }
}

Here is usage anywhere in viewcontroller:

这是视图控制器中任何地方的用法：

setStatusBar(color: .red)

setStatusBar(color: .red)
