Question

如何在Swift中以编程方式获取状态栏的高度？

在Objective-C中，它是这样的：

[UIApplication sharedApplication].statusBarFrame.size.height.

Answer 1

Swift 2.x ：

是否有任何问题

UIApplication.sharedApplication().statusBarFrame.size.height

Swift 3或Swift 4 ：

UIApplication.shared.statusBarFrame.height

确保导入UIKit

import UIKit

Answer 2

更新后的答案支持Swift 5的iOS 13及更高版本的iOS

 func getStatusBarHeight() -> CGFloat {
    var statusBarHeight: CGFloat = 0
    if #available(iOS 13.0, *) {
        let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
        statusBarHeight = window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
    } else {
        statusBarHeight = UIApplication.shared.statusBarFrame.height
    }
    return statusBarHeight
}

快乐编码！

Answer 3

斯威夫特只是一种不同的语言。 API元素是相同的。也许是这样的：

let app = UIApplication.sharedApplication()
let height = app.statusBarFrame.size.height

Answer 4

就像在Objective-C中一样：

var screenStatusBarHeight: CGFloat {
    return UIApplication.sharedApplication().statusBarFrame.height
}

这包含在以下标准变量中：

易卜拉欣修改后的答案：

extension UIApplication {
    static var statusBarHeight: CGFloat {
        var statusBarHeight: CGFloat = 0
        if #available(iOS 13.0, *) {
            let window = shared.windows.filter { $0.isKeyWindow }.first
            statusBarHeight = window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
        } else {
            statusBarHeight = shared.statusBarFrame.height
        }
        return statusBarHeight
    }
}

Answer 6

这是我使用的：

struct Screen {
    static var width: CGFloat {
        return UIScreen.main.bounds.width
    }
    static var height: CGFloat {
        return UIScreen.main.bounds.height
    }
    static var statusBarHeight: CGFloat {
        return UIApplication.shared.statusBarFrame.size.height
    }
}

那么您可以做：

Screen.statusBarHeight

在我的swiftUI项目中，此方法有效。

import UIKit
import SwiftUI

class SceneDelegate: UIResponder, UIWindowSceneDelegate {
    
    var window: UIWindow?

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        let contentView = ContentView()
        if let windowScene = scene as? UIWindowScene {
            let window = UIWindow(windowScene: windowScene)
            
            if let statusBarHeight = window.windowScene?.statusBarManager?.statusBarFrame.height {
            SceneDelegateDataGetter.shared.height = statusBarHeight
            }
            
            window.rootViewController = HostingController(rootView: contentView)
            self.window = window
            window.makeKeyAndVisible()
        }
    }

class SceneDelegateDataGetter {
    static let shared = SceneDelegateDataGetter()
    
    public fileprivate(set) var height: CGFloat = 0
}

使用时，

SceneDelegateDataGetter.shared.height

来自Peter Suwara 和Bobby 的回答

针对 Swift 5 进行了更新：

extension UIApplication {
    static var statusBarHeight: CGFloat {
        if #available(iOS 13.0, *) {
            let window = shared.windows.filter { $0.isKeyWindow }.first
            return window?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
        }
        return shared.statusBarFrame.height
    }
}

struct ScreenUtils {
    static var width: CGFloat {
        return UIScreen.main.bounds.width
    }
    
    static var height: CGFloat {
        return UIScreen.main.bounds.height
    }
    
    static var statusBarHeight: CGFloat {
        return UIApplication.statusBarHeight
    }
}

使用：

ScreenUtils.statusBarHeight
