swift中UIkit场景转换

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 UIKit
class 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 UIKit

class 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 UIKit

class 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 UIKit

class 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
    }
    
}
// PersonBLL
class 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 UIKit

class 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 UIKit

class 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
        }
    }
    
    
    
    
    }
