iOS获取状态栏的高度(support iOS13)

1. OC:

UIDevice+VGAddition.h

@interface UIDevice (VGAddition)

/// 顶部安全区高度
+ (CGFloat)vg_safeDistanceTop;

/// 底部安全区高度
+ (CGFloat)vg_safeDistanceBottom;

/// 顶部状态栏高度（包括安全区）
+ (CGFloat)vg_statusBarHeight;

/// 导航栏高度
+ (CGFloat)vg_navigationBarHeight;

/// 状态栏+导航栏的高度
+ (CGFloat)vg_navigationFullHeight;

/// 底部导航栏高度
+ (CGFloat)vg_tabBarHeight;

/// 底部导航栏高度（包括安全区）
+ (CGFloat)vg_tabBarFullHeight;

@end

UIDevice+VGAddition.m

#import "UIDevice+VGAddition.h"

@implementation UIDevice (VGAddition)

/// 顶部安全区高度
+ (CGFloat)vg_safeDistanceTop {
    if (@available(iOS 13.0, *)) {
        NSSet *set = [UIApplication sharedApplication].connectedScenes;
        UIWindowScene *windowScene = [set anyObject];
        UIWindow *window = windowScene.windows.firstObject;
        return window.safeAreaInsets.top;
    } else if (@available(iOS 11.0, *)) {
        UIWindow *window = [UIApplication sharedApplication].windows.firstObject;
        return window.safeAreaInsets.top;
    }
    return 0;
}

/// 底部安全区高度
+ (CGFloat)vg_safeDistanceBottom {
    if (@available(iOS 13.0, *)) {
        NSSet *set = [UIApplication sharedApplication].connectedScenes;
        UIWindowScene *windowScene = [set anyObject];
        UIWindow *window = windowScene.windows.firstObject;
        return window.safeAreaInsets.bottom;
    } else if (@available(iOS 11.0, *)) {
        UIWindow *window = [UIApplication sharedApplication].windows.firstObject;
        return window.safeAreaInsets.bottom;
    }
    return 0;
}


/// 顶部状态栏高度（包括安全区）
+ (CGFloat)vg_statusBarHeight {
    if (@available(iOS 13.0, *)) {
        NSSet *set = [UIApplication sharedApplication].connectedScenes;
        UIWindowScene *windowScene = [set anyObject];
        UIStatusBarManager *statusBarManager = windowScene.statusBarManager;
        return statusBarManager.statusBarFrame.size.height;
    } else {
        return [UIApplication sharedApplication].statusBarFrame.size.height;
    }
}

/// 导航栏高度
+ (CGFloat)vg_navigationBarHeight {
    return 44.0f;
}

/// 状态栏+导航栏的高度
+ (CGFloat)vg_navigationFullHeight {
    return [UIDevice vg_statusBarHeight] + [UIDevice vg_navigationBarHeight];
}

/// 底部导航栏高度
+ (CGFloat)vg_tabBarHeight {
    return 49.0f;
}

/// 底部导航栏高度（包括安全区）
+ (CGFloat)vg_tabBarFullHeight {
    return [UIDevice vg_statusBarHeight] + [UIDevice vg_safeDistanceBottom];
}

@end

2. Swift:

UIDevice+VGAddition.swift

extension UIDevice {
    
    /// 顶部安全区高度
    static func vg_safeDistanceTop() -> CGFloat {
        if #available(iOS 13.0, *) {
            let scene = UIApplication.shared.connectedScenes.first
            guard let windowScene = scene as? UIWindowScene else { return 0 }
            guard let window = windowScene.windows.first else { return 0 }
            return window.safeAreaInsets.top
        } else if #available(iOS 11.0, *) {
            guard let window = UIApplication.shared.windows.first else { return 0 }
            return window.safeAreaInsets.top
        }
        return 0;
    }
    
    /// 底部安全区高度
    static func vg_safeDistanceBottom() -> CGFloat {
        if #available(iOS 13.0, *) {
            let scene = UIApplication.shared.connectedScenes.first
            guard let windowScene = scene as? UIWindowScene else { return 0 }
            guard let window = windowScene.windows.first else { return 0 }
            return window.safeAreaInsets.bottom
        } else if #available(iOS 11.0, *) {
            guard let window = UIApplication.shared.windows.first else { return 0 }
            return window.safeAreaInsets.bottom
        }
        return 0;
    }
    
    /// 顶部状态栏高度（包括安全区）
    static func vg_statusBarHeight() -> CGFloat {
        var statusBarHeight: CGFloat = 0
        if #available(iOS 13.0, *) {
            let scene = UIApplication.shared.connectedScenes.first
            guard let windowScene = scene as? UIWindowScene else { return 0 }
            guard let statusBarManager = windowScene.statusBarManager else { return 0 }
            statusBarHeight = statusBarManager.statusBarFrame.height
        } else {
            statusBarHeight = UIApplication.shared.statusBarFrame.height
        }
        return statusBarHeight
    }
    
    /// 导航栏高度
    static func vg_navigationBarHeight() -> CGFloat {
        return 44.0
    }
    
    /// 状态栏+导航栏的高度
    static func vg_navigationFullHeight() -> CGFloat {
        return UIDevice.vg_statusBarHeight() + UIDevice.vg_navigationBarHeight()
    }
    
    /// 底部导航栏高度
    static func vg_tabBarHeight() -> CGFloat {
        return 49.0
    }
    
    /// 底部导航栏高度（包括安全区）
    static func vg_tabBarFullHeight() -> CGFloat {
        return UIDevice.vg_tabBarHeight() + UIDevice.vg_safeDistanceBottom()
    }
}

3. 机型判断:

iOS14 / iOS 15 适配新iPhone 12 / iPhone 13四种机型
