HI
Thank you for sharing your library.
I tried to use this library, but I found that iOS12 and iOS13 has a different shape.
Do you know how to solve it?

Thanks 🕺🏻

你好，请问页面push后导航栏整体下移是为什么

假设:

let vcs = self.navigationController?.viewControllers ?? []
self.navigationController?.setViewControllers(vcs.reversed(), animated: true)

setupNavigationBarWhenViewDidLoad()中的backBarButtonItem处理是不是就会有问题?

当前FirstVC会触发2种情况：

A. 正常的push下一个VC

B. 通过present展示modal：

       let eVC = FormViewController()
        eVC.title = "Form"
        let modal = MainNavigationController(rootViewController: eVC)
        self.present(modal, animated: true, completion: nil)

具体调用思路：

Root -> MainNavigationController -> FirstVC

A. FirstVC -> (Push) -> NextVc (标题为：Next)

B. FirstVC -> (Present Modal)-> MainNavigationController -> FormVC (标题为：Form)

出现的标题情况：

A. 显示为Next （正常）

B. 显示为Next（异常，标题应该显示为Form）

非全面屏iPhone7P iOS14.7 (全面屏正常)
在A->B->C页面跳转
B页面通过statusHidden = true ,重写prefersStatusBarHidden 隐藏状态栏后push到C或者pop到A页面 导航栏高度错误丢失状态栏高度,手动侧滑一下导航栏高度恢复正常
EachNavigationBar 版本 1.15.0, 1.15.1, 1.15.2 均可复现

override var prefersStatusBarHidden: Bool{
return statusHidden
}

The wrong location:
extension NextViewController: UIScrollViewDelegate {
func scrollViewDidScroll(_ scrollView: UIScrollView) {
let alpha = 1 - (scrollView.contentOffset.y) / (scrollView.contentSize.height - view.bounds.height)
navigation.bar.alpha = alpha
}
}

Error tip: Assertion failed: Please make sure UINavigationController navigation.configuration.isEnabled is true.: file EachNavigationBar/UIViewController+Navigation.swift.

A temporary change:
if ((navigationController?.navigation.configuration.isEnabled) != nil) {
navigation.bar.alpha = alpha
}
This's OK.

iOS 13 demo无法进行侧滑返回上一页

class EachNavigationBar line 71. 无法配置导航按钮样式 buttonAppearance无法赋值.

private lazy var appearance: UINavigationBarAppearance = {
let appearance = UINavigationBarAppearance()
appearance.backgroundColor = self.barTintColor
appearance.titleTextAttributes = self.titleTextAttributes ?? [:]
appearance.largeTitleTextAttributes = self.largeTitleTextAttributes ?? [:]

    return appearance
}()

一运行就报错了 找不到EachNavigationBar/EachNavigationBar-Swift.h OC 语言

I encounter a weird issue when I am using backItem
The navigation.configuration.backItem = .init(style: .custom(backButton))
after you push 2x to another controller it will show this issue when the user taps on the backItem button (custom)
the navigation pop 2x. this happens when I used .init(style: .custom(backButton)) but when i used the title and image it works fine. also tried to use the completion barkitem willBack , goBack and didBack for the custom to control those weird behavior that I encounter. I believe the button action target calls the number of stacks when the navigation push.

I tried to add searchController with this code but even in debug view hierarchy it doesn't appear.

navigation.item.searchController = UISearchController(searchResultsController: nil)
navigation.item.searchController?.searchBar.isHidden = false
navigation.item.searchController?.hidesNavigationBarDuringPresentation = false

有点不懂，是有什么 bug 导致必须这样做吗

首先，感谢如此之快的支持。谢谢！

在当前版本1.6.1：

1. 无法触发navigationItem跳转Segue，push下一个controller
2. 无法触发IBAction的方法

The example project could not find UINavigationBarAppearance

前后两个navigationBar颜色一样时动画最好跟系统一样

Storyboard的配置

效果

使用EachNavigationBar配置之后

能否获取到滑动返回的事件？

貌似不支持self.edgesForExtendedLayout = []

// NextViewController.swift
    override func viewDidLoad() {
        super.viewDidLoad()

        view.backgroundColor = UIColor.white
        view.addSubview(scrollView)
        view.addSubview(tipLabel)
        
        navigation.item.title = "Next"
        navigation.bar.tintColor = nil
        
        let titleView = UITextField(frame: CGRect(x: 0, y: 0, width: view.bounds.width - 100, height: 30))
        titleView.backgroundColor = UIColor.lightGray
        titleView.layer.cornerRadius = 15
        titleView.layer.masksToBounds = true
        navigation.item.titleView = titleView
        self.edgesForExtendedLayout = []
        if #available(iOS 11.0, *) {
            navigation.bar.prefersLargeTitles = false
        }
        
        navigation.bar.backBarButtonItem?.shouldBack = { item in
            let alert = UIAlertController(title: "确定退出", message: nil, preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "取消", style: .cancel, handler: nil))
            alert.addAction(UIAlertAction(title: "确定", style: .default) { _ in
                item.goBack()
            })
            self.present(alert, animated: true, completion: nil)
            debugPrint("shouldBack")
            return false
        }
    }

navigation.bar.statusBarStyle = .lightContent
这样设置没效果
请问哪里还需要设置呢？

这是原生的样子：

这是我尝试想要的：

可否提供offset设置？并且，内置一个漂亮的图标+文字的返回？

类似这种的

下面的断言条件base.navigationController?.navigation.configuration.isEnabled == true 是否是必要的?
通常在controller 侧滑手势进行中的时候, controller的navigationController是为nil的.
在这个时候修改任何属性都会触发断言, 例如网络请求 修改navigation.item.title.
或者在controller的init方法中设置navigation.item的属性也很难受.

    var bar: EachNavigationBar {
        assert(
            !(base is UINavigationController),
            "UINavigationController can't use this property, please use configuration."
        )
        assert(
            base.navigationController?.navigation.configuration.isEnabled == true,
            "Please make sure UINavigationController navigation.configuration.isEnabled is true."
        )
        return base._navigationBar
    }
    
    var item: UINavigationItem {
        assert(
            !(base is UINavigationController),
            "UINavigationController can't use this property, please use configuration."
        )
        assert(
            base.navigationController?.navigation.configuration.isEnabled == true,
            "Please make sure UINavigationController navigation.configuration.isEnabled is true."
        )
        return base._navigationItem
    }

建议支持开启配置后，又可以关闭配置。
场景：使用到第三方的控制器，不方便修改源码的时候

方案1：AOP, 看下是是否方便实现原生的方案，而不用创建一个新的Bar
方案2：navigation.configuration.isEnabled = false 还原现场，还原原生的样式

Since bringing this (fantastic) library in, my UI test has failed when trying to press the back button in the navigation bar. Do you know if there is a trick to getting it tappable at all?
I used to have app.navigationBars.buttons.element(boundBy: 0).tap(), but that is now failing with

Failed to synthesize event: Failed to scroll to visible (by AX action) Button, label: 'Back', error: Error kAXErrorCannotComplete performing AXAction 2003 on element AX element pid: 15737, elementOrHash.elementID: 105553178871296.256. (Underlying Error: Error kAXErrorCannotComplete performing AXAction 2003 on element AX element pid: 15737, elementOrHash.elementID: 105553178871296.256)

Any help appreciated.
Thanks a lot

如题，什么都没改，手势就没用

先在首页隐藏状态栏，然后 push 一个不隐藏状态栏的控制器，导航栏会与状态栏重叠。官方的 example 也会出现此问题。
iOS 11 正常，iOS 13 及 14 会出现，iOS 12 未测试。

横竖屏下状态栏高度也不一样？

旧版本 1.15.0没问题；
升级后出现导航栏高度不对；
let vc = SomeVc()
let nav = BaseNavigationController(rootViewController: vc!)
nav.navigation.configuration.isEnabled = true
.present(nav, animated: true, completion: nil)

在SomeVc里再push下一个页面，导致导航栏高度不对；

self.view一直是全屏大小，设置约束时必须使用self.view.safeAreaInsets.top

希望能内部修改self.view.top = self._navigationBar.bottom

https://github.com/DarielChen/SwiftTips#26

不能使用 edgesForExtendedLayout = UIRectEdge()，否则系统自带的navBar会显示在顶部，出现两个navBar

nav.setNavigationBarHidden(true, animated: false)
修改无效，UINavigationController.viewWillLayoutSubviews方法内已固定

func scrollViewDidScroll(_ scrollView: UIScrollView) {
let statusBarMaxY = navigationController!.navigationBar.frame.minY

Fatal error: Unexpectedly found nil while unwrapping an Optional value

如题

如题所述：
下面是不同的截图

场景 应用内黑白主题切换 主题发生变化是 重新设置navigation.configuration.barTintColor 并未立刻更新, 或者是否有提供手动触发UI刷新的方法?

设备系统：iOS12.4.4（iOS13以上展示正常）
相关代码：
self.navigation.item.titleView = searchView
searchView.frame = CGRect(x: 0, y: kNavBarHeight, width: kScreenWidth * 0.84, height: kSearchVHeight)
在searchView重写了：
override var intrinsicContentSize: CGSize {
return UIView.layoutFittingExpandedSize
}
宽度无法正常展示

之前用nav.navigation.configuration.backBarButtonItem 全局配置nav的返回按钮为一个图片。
现在取消了这个特性，要在每一个vc中添加。。。能再加上么。。
