   segmentC.frame = CGRect(x:80,y:200,width:200,height:30)
   self.view.addSubview(segmentC)
   segmentC.selectedSegmentIndex = 0
   
   //创建按钮控件
   factorybtn = ViewFactory.createButton(title: "确定", 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("我点击了")
 }

效果如下：
