EachNavigationBar為每個(gè)視圖控制器自定義導(dǎo)航條

pod 'EachNavigationBar'

github "Pircate/EachNavigationBar"

import EachNavigationBar

let nav = UINavigationController(rootViewController: vc)
nav.navigation.configuration.isEnabled = true

nav.navigation.configuration.titleTextAttributes = [.foregroundColor: UIColor.blue]

nav.navigation.configuration.barTintColor = UIColor.red

nav.navigation.configuration.shadowImage = UIImage(named: "shadow")

nav.navigation.configuration.setBackgroundImage(UIImage(named: "nav"), for: .any, barMetrics: .default)

nav.navigation.configuration.backItem = UINavigationController.Configuration.BackItem(style: .title("返回"))

nav.navigation.configuration.prefersLargeTitles = true

nav.navigation.configuration.largeTitle.displayMode = .always

// 一般用法同系統(tǒng)組件
navigation.bar  -> EachNavigationBar -> UINavigationBar
navigation.item -> UINavigationItem

// 隱藏導(dǎo)航欄
navigation.bar.isHidden = true

// 設(shè)置導(dǎo)航欄透明度
navigation.bar.alpha = 0.5

// 設(shè)置標(biāo)題透明度
navigation.bar.setTitleAlpha(0.5)

// 設(shè)置 barButtonItem 透明度
navigation.bar.setTintAlpha(0.5)
// 如果 barButtonItem 是自定義視圖
navigation.item.leftBarButtonItem?.customView?.alpha = 0.5
// 如果 barButtonItem 自定義了 tintColor
navigation.item.leftBarButtonItem?.tintColor = navigation.item.leftBarButtonItem?.tintColor?.withAlphaComponent(0.5)

// 移除毛玻璃效果
navigation.bar.isTranslucent = false

// 隱藏底部陰影
navigation.bar.isShadowHidden = true

// 設(shè)置狀態(tài)欄樣式
navigation.bar.statusBarStyle = .lightContent

// 設(shè)置返回按鈕
navigation.bar.backBarButtonItem = .init(style: .title("Back"), tintColor: .red)

// 允許返回事件
navigation.bar.backBarButtonItem.shouldBack = { item in
    // do something
    return false
}

// 返回事件之前回調(diào)
navigation.bar.backBarButtonItem.willBack = {
    // do something
}

// 返回事件之后回調(diào)
navigation.bar.backBarButtonItem.didBack = {
    // do something
}

// 如果想自定義導(dǎo)航欄位置，請將下面屬性設(shè)為 false
navigation.bar.automaticallyAdjustsPosition = false

// 導(dǎo)航欄附加高度
navigation.bar.additionalHeight = 14

// 導(dǎo)航欄附加視圖
navigation.bar.additionalView = UIView()

// 導(dǎo)航欄陰影
navigation.bar.shadow = Shadow(
    color: UIColor.black.cgColor,
    opacity: 0.5,
    offset: CGSize(width: 0, height: 3))

// 開啟大標(biāo)題
navigation.bar.prefersLargeTitles = true

// 顯示模式
navigation.item.largeTitleDisplayMode = .always

// 設(shè)置大標(biāo)題透明度
navigation.bar.setLargeTitleAlpha(0.5)

和使用系統(tǒng)導(dǎo)航欄完全一致。
