如下图创建两个视图，分别有两个按钮分别通往场景 下面有一个连线，连线时modal类型的

那去了B场景怎么回呢！虽然我门也可以通过连线来去B场景但不介意这样做（先练两种方法去a场景）

第一种方法如上图在b场景中写一个方法gotoA（）

第二种方法在a场景中写一个方法xxxxx（）来实现

在b场景中有一个这样的图片右键就能和A场景关联了

下面是A场景的视图控制器Aview

import UIKitclass Aview:UIViewController {        override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()    }        override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {        let dest = segue.destinationViewController as! Bview         dest.testName = "kangkang"            }    @IBAction func xxxxxx(xxx:UIStoryboardSegue){         let source = xxx.sourceViewController as! Bview     let data = source.toAdate           print(data)        }        }

下面是Bview

import UIKitclass Bview:UIViewController{        @IBOutlet weak var lablename: UILabel!      var testName:String?    var toAdate:String?    override func viewDidLoad() {        super.viewDidLoad()        lablename.text = testName    }    override func didReceiveMemoryWarning() {               super.didReceiveMemoryWarning()    }    @IBAction func goToA(sender:UIButton){         dismissViewControllerAnimated(true, completion: nil)        }          override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {        toAdate = "toadate ...."    }}

 哦！上面还有一个方法！那是在转换之前做的方法prepareForSegue（）

 

接下来的是导航视图控制器Navigation controller

行样式连线是用push的

下面我就来用视图控制器来视图控制器来做一个综合案例吧

如上图一样！一个列表和详情页

列表页的视图控制器

import UIKitclass myviewcontroll :UITableViewController{    var person:[Person]!        var per:Person?    override func viewDidLoad() {        super.viewDidLoad()        person = PersonImpl().generatePerson()            }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()    }        override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {        return person.count    }        override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {        let cell = tableView.dequeueReusableCellWithIdentifier("demo")!        let p = person[indexPath.row]        let nameLabel = cell.viewWithTag(1) as! UILabel        nameLabel.text = p.name        let ageLabel = cell.viewWithTag(2) as! UILabel        ageLabel.text = "\(p.age)"                return cell    }            override func tableView(tableView: UITableView, willSelectRowAtIndexPath indexPath: NSIndexPath) -> NSIndexPath? {              per = person[indexPath.row]                return indexPath      }           override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {        let dest = segue.destinationViewController as! myviewdetil          dest.person=per!                                     }            }

详情页的视图控制器

import UIKitclass myviewdetil:UIViewController{        @IBOutlet weak var personname: UILabel!    @IBOutlet weak var personage: UILabel!        var person:Person?       override func viewDidLoad() {        super.viewDidLoad()        personname.text = person?.name        personage.text = "\(person!.age)"    }}

写一个Person类来存数据

import UIKit//模型类class Person {    var name: String    var age: Int    init(name: String,age: Int){        self.name = name        self.age = age    }    }// PersonBLLclass PersonImpl {    func generatePerson() -> [Person] {        //persondao. //persondal.()        var result = [Person]()        let p = Person(name: "kangkang", age: 11)        result.append(p)                let p2 = Person(name: "lucy", age: 22)        result.append(p2)                let p3 = Person(name: "rose", age: 33)        result.append(p3)        return result            }}

关于表格的单选。写一个像列表的视图控制器如上面的列表。person类和上面的一样

import UIKitclass RadioSelect: UITableViewController {        var person:[Person]!    override func viewDidLoad() {        super.viewDidLoad()        person = PersonImpl().generatePerson()            }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()    }        override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {                        return person.count    }        override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {        let cell = tableView.dequeueReusableCellWithIdentifier("demo")!        let p = person[indexPath.row]        let nameLabel = cell.viewWithTag(1) as! UILabel        nameLabel.text = p.name        let ageLabel = cell.viewWithTag(2) as! UILabel        ageLabel.text = "\(p.age)"                return cell    }       override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {                //取消选中单元格样式        tableView.deselectRowAtIndexPath(indexPath, animated: true)                let cell:UITableViewCell!=tableView.cellForRowAtIndexPath(indexPath)        var arr=tableView.visibleCells        //遍历取消所有单元格样式                for(var i=0 ; i < arr.count ; i++){                    let cells = arr[i]            cells.accessoryType = UITableViewCellAccessoryType.None        }        //设置选中的单元格样式                cell.accessoryType = UITableViewCellAccessoryType.Checkmark                                    }            }

多选

import UIKitclass Duoxuan: UITableViewController {    var person:[Person]!                    override func viewDidLoad() {        super.viewDidLoad()        person = PersonImpl().generatePerson()            }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()    }        override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {                       return person.count    }        override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {        let cell = tableView.dequeueReusableCellWithIdentifier("demo")!        let p = person[indexPath.row]        let nameLabel = cell.viewWithTag(1) as! UILabel        nameLabel.text = p.name        let ageLabel = cell.viewWithTag(2) as! UILabel        ageLabel.text = "\(p.age)"               return cell    }    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {      let cell = tableView.cellForRowAtIndexPath(indexPath)        if(cell?.accessoryType == UITableViewCellAccessoryType.Checkmark)        {            cell?.accessoryType = UITableViewCellAccessoryType.None        }        else{        cell?.accessoryType = UITableViewCellAccessoryType.Checkmark        }    }                    }
