变化与条件

Question

喜我想去与条件下一个视图中textfiled 2进入secondview和tetxtfiled 3去时thirdview

我不想navgation控制或标签视图

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？）方法被调用，你需要执行segue。在您的代码中，您只是将视图控制器推送到导航堆栈而不执行segue。

如果在你的故事板一个赛格瑞你可以叫self.navigationController .pushViewController的

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

isntead（thirdPageView，动画：真）？你只需要创建第二和第三两种不同的塞格斯view controller
