swift3 傳遞資料到下一頁的方法(二)-以取得下一頁storyboard Id的方式

  1. First generate SecondViewController.swift ,then set the storyboard id = next
 

2.set two button function = goNext

 

3.in SecondViewController generate a property name , then set self.namelabel.text = name

 

4. the whole code is below, then we analysis the code step by step like below (4.1,4.2,4.3)

 

4.1 In goNext function ,first use self.storyboard?.instantiateViewController(withIdentifier: “next”) to obtain the controller but need to tranform to SecondViewController

 

4.2 because we know the sender is UIButton , so it can set controller.name = sender.currentTitle

 

4.3 finally we need to present the controller ,then it will show

 

5. run the app
