這篇文章主要為大家詳細(xì)介紹了swift控件工廠類的實(shí)現(xiàn)代碼，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

控件工廠類，簡(jiǎn)而言之就是，減少代碼的復(fù)用率，只在哪里用，然后在哪里調(diào)：

代碼如下：

import UIKit

class ViewFactory: UIView,UITextFieldDelegate {

  //默認(rèn)控件的尺寸
  class func getDefaultFrame( ) -> CGRect
  {
    let defaultFrame = CGRect(x:0,y:0,width:100,height:30)
    return defaultFrame
  }
  
  //類方法
  class func createControl(type:String,title:[String],action:Selector,sender:AnyObject) -> UIView
  {
    switch type {
    case "label":
      return ViewFactory.creatLabel(title: title[0])
      case "button":
      return ViewFactory.createButton(title: title[0], action: action, sender: sender as! UIViewController)
      case "text":
      return ViewFactory.creatTextField(value: title[0], action: action, sender: sender as! UIViewController as UIViewController as! UITextFieldDelegate)
      case "segment":
      return ViewFactory.creatSegment(items: [title[0]], action: action, sender: sender as! UIViewController)
    default:
      return ViewFactory.creatLabel(title: title[0])
    }
  }
  
  //創(chuàng)建按鈕控件
  class func createButton(title:String, action:Selector, sender:UIViewController)
    -> UIButton {
      let button = UIButton(frame:ViewFactory.getDefaultFrame())
      button.backgroundColor = UIColor.orange
      button.setTitle(title, for:.normal)
      button.titleLabel!.textColor = UIColor.white
      button.titleLabel!.font = UIFont.systemFont(ofSize: 14)
      button.addTarget(sender, action:action, for:.touchUpInside)
      return button
  }
  
  //創(chuàng)建文本輸入框控件
  class func creatTextField(value:String,action:Selector,sender:UITextFieldDelegate) -> UITextField
  {
    let textField = UITextField(frame:ViewFactory.getDefaultFrame())
    textField.backgroundColor = UIColor.clear
    textField.textColor = UIColor.black
    textField.text = value
    textField.borderStyle = .roundedRect
    textField.adjustsFontSizeToFitWidth = true
    textField.delegate = sender
    return textField
  }
  
  //創(chuàng)建分段單選組件
  class func creatSegment(items:[String],action:Selector,sender:UIViewController) -> UISegmentedControl
  {
    let segment = UISegmentedControl(items:items)
    segment.frame = ViewFactory.getDefaultFrame()
    segment.isMomentary = false
    segment.addTarget(self, action: action, for: .valueChanged)
    return segment
  }
  
  //創(chuàng)建文本標(biāo)簽控件
  class func creatLabel(title:String) -> UILabel
  {
    let label = UILabel()
    label.textColor = UIColor.black
    label.backgroundColor = UIColor.white
    label.text = title
    label.frame = ViewFactory.getDefaultFrame()
    label.font = UIFont(name:"微軟雅黑",size:16)
    return label
    
  }
}

調(diào)用：

 func initVIewFactory()
  {
    //創(chuàng)建文本標(biāo)簽
    let labelNum = ViewFactory.creatLabel(title: "閾值")
    labelNum.frame = CGRect(x:20,y:100,width:60,height:30)
    self.view.addSubview(labelNum)
    
    let labelDm = ViewFactory.creatLabel(title: "維度")
    labelDm.frame = CGRect(x:20,y:200,width:60,height:30)
    self.view.addSubview(labelDm)
    
    //創(chuàng)建文本輸入框
    textNum = ViewFactory.creatTextField(value: "", action:#selector(factoryAction), sender: self as UITextFieldDelegate)
    textNum.frame = CGRect(x:80,y:100,width:200,height:30)
    textNum.returnKeyType = .done
    self.view.addSubview(textNum)
    
    let textNumSecond = ViewFactory.creatTextField(value: "", action: #selector(factoryActionSecond), sender: self as UITextFieldDelegate)
    textNumSecond.frame = CGRect(x:80,y:200,width:200,height:30)
    textNum.returnKeyType = .done
    self.view.addSubview(textNumSecond)
    
    //創(chuàng)建分段單選控件
    segmentC = ViewFactory.creatSegment(items: ["3*3","4*4","5*5"], action: #selector(segmentAction), sender: self)
    segmentC.frame = CGRect(x:80,y:200,width:200,height:30)
    self.view.addSubview(segmentC)
    segmentC.selectedSegmentIndex = 0
    
    //創(chuàng)建按鈕控件
    factorybtn = ViewFactory.createButton(title: "確定", action: #selector(factoryClick), sender: self)
    factorybtn.frame.origin = CGPoint(x:80,y:300)
    self.view.addSubview(factorybtn)
    
  }
  
  func factoryAction()
  {
    
  }
  
  func factoryActionSecond()
  {
    
  }
  
  func segmentAction()
  {
    
  }
  
  func factoryClick()
  {
    print("我點(diǎn)擊了")
  }

效果如下：
