SwiftFullScreenPop - 基于Swift3.0实现全屏侧滑返回
Features
- 解决自定义navigationBar侧滑返回不能用快速帮你实现侧滑返回功能。
- 解决当某个界面navigationBar隐藏时下个界面有导航导致侧滑返回体验很差。
- 解决UIScrollView不能使用侧滑返回。
CocoaPods
platform :ios, '7.0'
target 'Your Project' do
pod 'SwiftFullScreenPop'
end
Usage
- 在需要使用的地方导入头文件
import SwiftFullScreenPop - 可以在自己的UINavigationController基类里面加入下面代码
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
UINavigationController.swizzle()
UIViewController.viewControllerSwizzle()
}
- 在ViewController里面直接使用
// 不支持侧滑true
isInteractivePopDisable = true
// 隐藏当前页面导航
self.isPrefersNavigationBarHidden = true
Swizzle
- 基于extension UInavigationController 和 extension UIViewController实现swizzle controller push function；viewWillAppear and ViewWillDisappear
DispatchQueue.once(token: Static.token) {
let originalSelector = #selector(UINavigationController.pushViewController(_:animated:))
let swizzlerSelector = #selector(UINavigationController.myPushViewController(_:animated:))
let originalMethod = class_getInstanceMethod(UINavigationController.self, originalSelector)
let swizzlerMethod = class_getInstanceMethod(UINavigationController.self, swizzlerSelector)
//在进行 Swizzling 的时候,需要用 class_addMethod 先进行判断一下原有类中是否有要替换方法的实现
let isAddMethod = class_addMethod(UINavigationController.self, originalSelector, method_getImplementation(swizzlerMethod), method_getTypeEncoding(swizzlerMethod))
if isAddMethod
{
class_replaceMethod(UINavigationController.self, swizzlerSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod))
}else {
method_exchangeImplementations(originalMethod, swizzlerMethod)
}
}
DispatchQueue.once(token: Static.token) {
let originalSelector = #selector(UIViewController.viewWillAppear(_:))
let swizzlerSelector = #selector(UIViewController.myViewWillApper(_:))
let originalMethod = class_getInstanceMethod(self, originalSelector)
let swizzlerMethod = class_getInstanceMethod(self, swizzlerSelector)
let isAddMethod: Bool = class_addMethod(self, originalSelector, method_getImplementation(swizzlerMethod), method_getTypeEncoding(swizzlerMethod))
if isAddMethod
{
class_replaceMethod(self, swizzlerSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod))
}else {
method_exchangeImplementations(originalMethod, swizzlerMethod)
}
let disappear_originalSEL = #selector(UIViewController.viewWillDisappear(_:))
let disappear_swizzleSEL = #selector(UIViewController.myViewWillDisappear(_:))
let disappear_originalMethod = class_getInstanceMethod(self, disappear_originalSEL)
let disappear_swizzleMethod = class_getInstanceMethod(self, disappear_swizzleSEL)
let isAdd: Bool = class_addMethod(self, disappear_originalSEL, method_getImplementation(disappear_swizzleMethod), method_getTypeEncoding(disappear_swizzleMethod))
if isAdd {
class_replaceMethod(self, disappear_swizzleSEL, method_getImplementation(disappear_originalMethod), method_getTypeEncoding(disappear_originalMethod))
}else {
method_exchangeImplementations(disappear_originalMethod, disappear_swizzleMethod)
}
}

在实现cocoaPods遇到的坑
[!] The validator for Swift projects uses Swift 3.0 by default, if you are using a different version of swift you can use a `.swift-version` file to set the version for your Pod. For example to use Swift 2.3, run:
`echo "2.3" > .swift-version`.
在终端里面执行：echo "3.0" > .swift-version
- 如果提示Authentication token is invalid or unverified. Either verify it with the email that was sent or register a new session.
重新在终端里面执行：pod trunk register 邮箱名 “用户名”再到邮箱里面重新验证即可 - 如果想知道如何实现自己的代码用cocoapods管理可移动我的简书文章
顺便提及下关于本地的代码如何git管理主要以下几步
- git init. //当前需要提交的文件路径，和github上面XXXX.git一致
- git add filename
- git commit -m '提交信息说明' //添加描述
- git pull //数据同步
- git push origin master //提交数据
- 遇到如下错误
error: failed to push some refs to 'git@github.com:LeeFengHY/SwiftFullScreenPop.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
是因为远程repository和我本地的repository冲突导致的，如下解决方法：
- 1:
git pull origin master
git push -u origin master - 2:若不想merge远程和本地修改，可以先创建新的分支：
git branch [name]
git push -u origin [name]
