變化與條件

Question

喜我想去與條件下一個視圖中textfiled 2進入secondview和tetxtfiled 3去時thirdview

我不想navgation控制或標籤視圖

class ViewController: UIViewController { 

@IBOutlet weak var text: UITextField! 
@IBAction func nextview(sender: UIButton) { 

    if text.text == "2"{ 

     let secondView = self.storyboard?.instantiateViewControllerWithIdentifier("second") as! SecondView 
     self.navigationController?.pushViewController(secondView, animated: true) 
    } 
    else{ 

     let thirdPageView = self.storyboard?.instantiateViewControllerWithIdentifier("third") as! ThirdView 
     self.navigationController?.pushViewController(thirdPageView, animated: true) 
    } 

} 
override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 
} 

我也使用prepersguewithidentifire，但不工作！ 我很困惑

Answer 1

如果你想要你prepareForSegue（segue：UIStoryboardSegue，sender：AnyObject？）方法被調用，你需要執行segue。在您的代碼中，您只是將視圖控制器推送到導航堆棧而不執行segue。

如果在你的故事板一個賽格瑞你可以叫self.navigationController .pushViewController的

func performSegueWithIdentifier(_ identifier: String, 
         sender sender: AnyObject?) 

isntead（thirdPageView，動畫：真）？你只需要創建第二和第三兩種不同的塞格斯view controller
