控件工厂类，简而言之就是，减少代码的复用率，只在哪里用，然后在哪里调：
代码如下：
import UIKit
class ViewFactory: UIView,UITextFieldDelegate {
//默认控件的尺寸
class func getDefaultFrame( ) -> CGRect
{
let defaultFrame = CGRect(x:,y:,width:,height:)
return defaultFrame
}
//类方法
class func createControl(type:String,title:[String],action:Selector,sender:AnyObject) -> UIView
{
switch type {
case "label":
return ViewFactory.creatLabel(title: title[])
case "button":
return ViewFactory.createButton(title: title[], action: action, sender: sender as! UIViewController)
case "text":
return ViewFactory.creatTextField(value: title[], action: action, sender: sender as! UIViewController as UIViewController as! UITextFieldDelegate)
case "segment":
return ViewFactory.creatSegment(items: [title[]], action: action, sender: sender as! UIViewController)
default:
return ViewFactory.creatLabel(title: title[])
}
}
//创建按钮控件
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: )
button.addTarget(sender, action:action, for:.touchUpInside)
return button
}
//创建文本输入框控件
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
}
//创建分段单选组件
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
}
//创建文本标签控件
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:"微软雅黑",size:)
return label
}
}调用：
func initVIewFactory()
{
//创建文本标签
let labelNum = ViewFactory.creatLabel(title: "阈值")
labelNum.frame = CGRect(x:,y:,width:,height:)
self.view.addSubview(labelNum) let labelDm = ViewFactory.creatLabel(title: "维度")
labelDm.frame = CGRect(x:,y:,width:,height:)
self.view.addSubview(labelDm) //创建文本输入框
textNum = ViewFactory.creatTextField(value: "", action:#selector(factoryAction), sender: self as UITextFieldDelegate)
textNum.frame = CGRect(x:,y:,width:,height:)
textNum.returnKeyType = .done
self.view.addSubview(textNum) let textNumSecond = ViewFactory.creatTextField(value: "", action: #selector(factoryActionSecond), sender: self as UITextFieldDelegate)
textNumSecond.frame = CGRect(x:,y:,width:,height:)
textNum.returnKeyType = .done
self.view.addSubview(textNumSecond) //创建分段单选控件
segmentC = ViewFactory.creatSegment(items: ["3*3","4*4","5*5"], action: #selector(segmentAction), sender: self)
segmentC.frame = CGRect(x:,y:,width:,height:)
self.view.addSubview(segmentC)
segmentC.selectedSegmentIndex = //创建按钮控件
factorybtn = ViewFactory.createButton(title: "确定", action: #selector(factoryClick), sender: self)
factorybtn.frame.origin = CGPoint(x:,y:)
self.view.addSubview(factorybtn) } func factoryAction()
{ } func factoryActionSecond()
{ } func segmentAction()
{ } func factoryClick()
{
print("我点击了")
}
效果如下：
