分享一个基于Swift3.0的ios入门学习Demo
看Swift基础有一段时间了，但是很少实践，最近准备抽时间把ios的基础过一遍，就给自己设计了这样一套作业（还有很多没完成，后续更新）。根据以前android的自学经验，入门涉及UI组件基础、自定义组件、数据存储、线程、网络、多媒体，当然你还有可能接触游戏开发。

目前工程已经涉及到Autolayout、网络、json和一些基本UI组件的使用，还有一些线程的使用（之前学习线程有单独写过帖子，这次就没有专门做这部分），以下是部分事例代码。

@objc func showCustom() {    let  customAlert = UIAlertController(title: "登陆", message: "请输入用户名跟密码", preferredStyle: .alert)    customAlert.addTextField{        (textfield: UITextField) -> Void in        textfield.placeholder="输入用户名"    }    customAlert.addTextField{        (textfield: UITextField) -> Void in        textfield.placeholder="输入密码"    }    let oneAction = UIAlertAction(title: "取消", style: .cancel, handler: nil)    let twoAction = UIAlertAction(title: "登陆", style: .destructive, handler: nil)    customAlert.addAction(oneAction)    customAlert.addAction(twoAction)    controller?.present(customAlert, animated: true, completion: nil)}

    override func loadUi(controller: UIViewController) {    super.loadUi(controller: controller)    guard let rootView = controller.view else {        return    }    //UISlider    slider = UISlider()    AutoLayoutUtils.utils.setView(view: slider, parent: rootView)    .markSize(height: 60)    .markTo(toView: rootView)    .mark(top: 72, leading: 6, trailing: -6)    .cimmit()    slider!.minimumValue = 0    slider!.maximumValue = 1    slider!.value = 0.5    //设置滑块停止后通知改变 默认true//        slider.isContinuous = false    slider!.addTarget(self, action: #selector(WidgetsLoader_01.sliderValueChanged(slider:)), for: .valueChanged)    //UIProgressView    progress = UIProgressView()    AutoLayoutUtils.utils.setView(view: progress, parent: rootView)        .markSize(height: 5)        .markTo(toView: slider)        .align(top: 10)        .mark(leading: 6, trailing: -6, to: rootView)        .cimmit()    progress!.progress = 0.5    let label = UILabel()    AutoLayoutUtils.utils.setView(view: label, parent: rootView)        .markSize(width: 280, height: 60)        .markTo(toView: progress)        .align(top: 6)        .mark(leading:0)        .cimmit()    label.text = "slider变化是否在滑块停止后更新"    //UISwitch    let sw = UISwitch()    AutoLayoutUtils.utils.setView(view: sw, parent: rootView)        .mark(centerY: 0, to: label)        .mark(trailing: 0, to: progress)        .cimmit()    sw.addTarget(self, action: #selector(WidgetsLoader_01.swithDidChanged(swith:)), for: .valueChanged)    //UISegmentedControl    let items = ["第一项","第二项","第三项"]    let segmentCtl = UISegmentedControl(items: items)    AutoLayoutUtils.utils.setView(view: segmentCtl, parent: rootView)        .align(top: 10, to: label)        .mark(centerX: 0, to: rootView)        .cimmit()    //    segmentCtl.addTarget(self, action: #selector(WidgetsLoader_01.segmentDidChanged(segment:)), for: .valueChanged)    segmentCtl.selectedSegmentIndex = 0    self.segmentCtl = segmentCtl    let segmentStateLabel = UILabel()    segmentStateLabel.text="选择了第0项"    AutoLayoutUtils.utils.setView(view: segmentStateLabel, parent: rootView)        .markSize(width: 200, height: 40)        .align(top: 2, to: segmentCtl)        .mark(centerX: 0, to: rootView)        .cimmit()    segmentStateLabel.textAlignment = .center    self.segmentStateLabel = segmentStateLabel    let addBtn = UIButton()    addBtn.setTitle("添加", for: .normal)    addBtn.setTitleColor(UIColor.blue, for: .normal)    addBtn.setTitleColor(UIColor.green, for: .highlighted)    addBtn.addTarget(self, action: #selector(WidgetsLoader_01.addItem), for: .touchUpInside)    AutoLayoutUtils.utils.setView(view: addBtn, parent: rootView)        .markSize(width: 100, height: 30)        .align(top: 2, to: segmentStateLabel)        .mark(leading: 0, to: segmentCtl)        .cimmit()    let deleteBtn = UIButton()    deleteBtn.setTitle("删除", for: .normal)    deleteBtn.setTitleColor(UIColor.blue, for: .normal)    deleteBtn.setTitleColor(UIColor.green, for: .highlighted)    deleteBtn.addTarget(self, action: #selector(WidgetsLoader_01.removeItem), for: .touchUpInside)    AutoLayoutUtils.utils.setView(view: deleteBtn, parent: rootView)        .markSize(width: 100, height: 30)        .align(top: 2, to: segmentStateLabel)        .mark(trailing: 0, to: segmentCtl)        .cimmit()}

func get(url: String, callback: @escaping (_ weather: [String: Any]?)->()) {    let  url = URL(string: url)    let session = URLSession(configuration: URLSessionConfiguration.default)    let  task = session.dataTask(with: url!, completionHandler: {        (data: Data?, reponse: URLResponse?, error: Error?) -> Void in        if error == nil {            do {                let dict = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as?
