AppDelegate
var window: UIWindow? func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { var VC = ViewController() var nav = UINavigationController(rootViewController: VC) self.window = UIWindow(frame: UIScreen.mainScreen().bounds) self.window!.rootViewController = nav self.window?.backgroundColor = UIColor.whiteColor() self.window?.makeKeyAndVisible() return true }
ViewController
引入代理,注意这里在完成dataSource的几个方法之前,UITableViewDataSource会报错,完成之后就好了
@H_403_20@class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource
定义tableView 和 数据源
var _tableView:UITableView? var _dataSource = ["星期一","星期二","星期三","星期四","星期五","星期六","星期日"] override func viewDidLoad() { super.viewDidLoad() //配置导航栏 self.navigationItem.title = "单元格滑动可删除" var leftBtn = UIBarButtonItem(title: "Add",style: UIBarButtonItemStyle.Plain,target: self,action:"add") var rightBtn = UIBarButtonItem(title: "Move",action: "edit:") rightBtn.tag = 100 self.navigationItem.leftBarButtonItem = leftBtn self.navigationItem.rightBarButtonItem = rightBtn //配置表 _tableView = UITableView(frame: self.view!.bounds) _tableView?.delegate = self _tableView?.dataSource = self self.view .addSubview(_tableView!) }
导航按钮点击事件
//导航按钮点击事件 func add() { println("add sth") _dataSource .append("一周就七天") _tableView?.reloadData() } func edit(rightBtn:UIBarButtonItem) { println("edit tableView") if(rightBtn.tag == 100) { _tableView?.setEditing(true,animated: true) rightBtn.tag = 200 rightBtn.title = "done" } else { _tableView?.setEditing(false,animated: true) rightBtn.tag = 100 rightBtn.title = "edit" } }
UITableViewDataSource UITableViewDelegate
//UITableViewDataSource UITableViewDelegate //行数 func tableView(tableView: UITableView,numberOfRowsInSection section: Int) -> Int { return _dataSource.count } //单元格内容 func tableView(tableView: UITableView,cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { let identifier = "Cell" var cell = tableView.dequeueReusableCellWithIdentifier(identifier)as? UITableViewCell; if(cell == nil) { cell = UITableViewCell(style:UITableViewCellStyle.Default,reuseIdentifier: identifier) } cell?.textLabel?.text = _dataSource[indexPath.row] return cell! } //是否允许打开编辑状态 默认是 可以不写 func tableView(tableView: UITableView,canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool { return true } func tableView(tableView: UITableView,editingStyleForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCellEditingStyle { //允许滑动删除 if(_tableView?.editing == false) { return UITableViewCellEditingStyle.Delete } //移动单元格 else { return UITableViewCellEditingStyle.None } } //删除某行 func tableView(tableView: UITableView,commitEditingStyle editingStyle: UITableViewCellEditingStyle,forRowAtIndexPath indexPath: NSIndexPath) { _dataSource.removeAtIndex(indexPath.row) _tableView?.reloadData() } //允许移动某行 func tableView(tableView: UITableView,canMoveRowAtIndexPath indexPath: NSIndexPath) -> Bool { return true } //移动 func tableView(tableView: UITableView,moveRowAtIndexPath sourceIndexPath: NSIndexPath,toIndexPath destinationIndexPath: NSIndexPath) { _tableView?.moveRowAtIndexPath(sourceIndexPath,toIndexPath: destinationIndexPath) var itemToMove = _dataSource[sourceIndexPath.row] //在这里找不到数组exchange的方法, 所以采用先移除后添加来实现交换位置 _dataSource.removeAtIndex(sourceIndexPath.row) _dataSource.insert(itemToMove,atIndex: destinationIndexPath.row) } //cell点击事件 func tableView(tableView: UITableView,didSelectRowAtIndexPath indexPath: NSIndexPath) { switch indexPath.row { case 0: self.navigationController?.pushViewController(FirstViewController(),animated: true) case 1: self .presentViewController(SecondViewController(),animated: true,completion: nil) case 2: self.navigationController?.pushViewController(ThirdViewController(),animated: true) default: var alert = UIAlertView(title: "提示",message: "不是前三",delegate: nil,cancelButtonTitle: "cancel") alert.show() } }
SecondViewController
override func viewDidLoad() { super.viewDidLoad() self.navigationItem.title = "Second" self.view.backgroundColor = UIColor.redColor() var button = UIButton(frame: self.view.bounds) button.addTarget(self,action: "buttonClick",forControlEvents: UIControlEvents.TouchUpInside) button.setTitle("点击屏幕返回",forState: UIControlState.Normal) self.view.addSubview(button) } func buttonClick() { print("buttonClick") self .dismissViewControllerAnimated(true,completion: nil) }
ThirdViewController
@H_403_20@override func viewDidLoad() { super.viewDidLoad() self.navigationItem.title = "Third" self.view.backgroundColor = UIColor.greenColor() var button = UIButton(frame: self.view.bounds) button.addTarget(self,forControlEvents: UIControlEvents.TouchUpInside) button.setTitle("点击屏幕去根视图",forState: UIControlState.Normal) self.view.addSubview(button) } func buttonClick() { print("buttonClick") self.navigationController?.popToRootViewControllerAnimated(true) } 原文链接:https://www.f2er.com/swift/326882.html
