系统控件和自定义控件

如下图创建一个导航视图控制器 三个场景，第二个场景和第三个有线连接modal

 

上面的Edit是一个item

中间那个的控制器

import UIKit

class EditModeTableviewControll: UITableViewController {
    
    
    
    var persons = Person.getDate()
    var per:Person?
    
    override func viewDidLoad() {
       
        super.viewDidLoad()
       //自定义的
        self.navigationItem.rightBarButtonItem=editButtonItem()
    }
    @IBAction func toEdit(sender: UIBarButtonItem) {
        tableView.setEditing(true, animated: true)
    }
    override func didReceiveMemoryWarning() {
       
        super.didReceiveMemoryWarning()
    }
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        
        return persons.count
    }
    override func tableView(tableView: UITableView, willSelectRowAtIndexPath indexPath: NSIndexPath) -> NSIndexPath? {
        
        per = persons[indexPath.row]
        
        return indexPath
    }
    
    
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        
        let cell=tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath:indexPath)
        
        let p=persons[indexPath.row]
        
        cell.textLabel?.text = p.name
       
        return cell
    }
   //这个函数实现功能
    override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == .Delete {
        persons.removeAtIndex(indexPath.row)
        tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
        }else{
            let p = Person(name:"new")
            persons.append(p)
            tableView.insertRowsAtIndexPaths([NSIndexPath(forRow:indexPath.row+1,inSection:0)], withRowAnimation: .Fade)
        
        }
        
    }
   //写行样式
    override func tableView(tableView: UITableView, editingStyleForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCellEditingStyle {
        if indexPath.row == persons.count - 1{
          return .Insert
        }else{
          return .Delete
        }
    }
//跳转的时候传值
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
       let dest = segue.destinationViewController as! myviewdetil
        dest.person=per!
        
        dest.persondel = self
    }

}

//进行刷新
    extension EditModeTableviewControll : persondelegate {
    func person() {

        tableView.reloadData()
    }
}

person 类

import Foundation
class Person{
    var name:String
    init(name:String){
     self.name = name
    
    }
    static func getDate()->[Person]{
     return [
        Person(name:"1111"),
        Person(name:"2222"),
        Person(name:"3333"),
        Person(name:"4444")
        
        
        ]
    
    
    }



}

第三个视图的

import UIKit

class myviewdetil: UIViewController {
    var person:Person?
    var persondel: persondelegate?
    
    @IBOutlet weak var mytxt: UITextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        mytxt.text = person?.name
        
        
    }
    
    @IBAction func tojumplist(sender: UIButton) {
         person?.name = mytxt.text!
        persondel?.person()
        dismissViewControllerAnimated(true, completion: nil)
        
    }
}

delelegate

import Foundation
protocol persondelegate{


    func person()


}

上面的是系统的控件如下图写一个自定义的控件

这个是放图片的地方

如图创建一个场景

下面是场景的控制器

import UIKit

class mytableviewcontroll: UIViewController {
    
    @IBOutlet weak var rartingyou: RatingControll!
    @IBOutlet weak var mylable: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
       let vc = view.viewWithTag(1) as! RatingControll
        vc.startDe = self
       rartingyou.rating = 3
        mylable.text = "当前评价值指数：(rartingyou.rating)星"
        // Do any additional setup after loading the view.
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
   

}
extension mytableviewcontroll : startdelegate {
    func Startcount(sender:RatingControll) {
       mylable.text = "当前评价值指数：(sender.rating)星"
    }
}

视图里面的view控制器

import UIKit

class RatingControll:UIView{
var startDe:startdelegate?
  var rating = 0 //表示当前好评值
  var ratingcount = 5 //内部数量
  let spacing = 5 //表示按钮间的距离
  var buttons = [UIButton]()
    //把按钮创建出来
    required init?(coder aDecoder: NSCoder){
      super.init(coder:aDecoder)
        for _ in 0..<ratingcount {
            let btn = UIButton(frame: CGRect(x:0, y:0, 44, height:44))
            btn.addTarget(self, action: "btnClicked:", forControlEvents: .TouchDown)
            btn.setImage(UIImage(named: "empty"), forState: .Normal)
             btn.setImage(UIImage(named: "filled"), forState: .Selected)
            btn.adjustsImageWhenHighlighted = false
            buttons.append(btn)
            addSubview(btn)
        }
    
    
    }
   //代表星星的位置
    override func layoutSubviews() {
        for (index,btn) in buttons.enumerate(){
        
        btn.frame.origin.x = CGFloat((44 + spacing ) * index)
        
        }
      update()
        
    }
   //
    func btnClicked(btn: UIButton) {
      rating = buttons.indexOf(btn)!+1
        update()
     // 进行传參
        startDe?.Startcount(self)
      //  print("bynclick")
    }
    //设置星星的样式
    func update() {
        for (index,btn) in buttons.enumerate() {
            if index < rating {
              btn.selected = true
            }else {
             btn.selected = false
            
            }
        
        }
    }

startdelegate

import Foundation
protocol startdelegate{

    func Startcount(sender:RatingControll);

}
