ios – 在新的Storyboard中将值传递给UIViewController – Swift

概述我试图将值传递给新的视图控制器 – 位于新的故事板文件中.但是当我这样做时,我从NewViewController得到的结果总是为零. 下面是我在新故事板中显示视图控制器的方法： // Show create account page with custom transitionvar storyboard : UIStoryboard = UIStoryboard(name: Storyboa 我试图将值传递给新的视图控制器 – 位于新的故事板文件中.但是当我这样做时,我从NewVIEwController得到的结果总是为零.

下面是我在新故事板中显示视图控制器的方法：

// Show create account page with custom Transitionvar storyboard : UIStoryboard = UIStoryboard(name: Storyboardname,bundle: nil)var vc : UIVIEwController = storyboard.instantiateVIEwControllerWithIDentifIEr(NewVIEwController) as UIVIEwController

我尝试在这里发送信息：

// Pass the delegate to the first vIEw controllerlet newVIEwController:NewVIEwController = NewVIEwController()newVIEwController.createAccountDelegate = selfnewVIEwController.teststring = "hello"

然后呈现视图控制器.

vc.TransitioningDelegate = selfvc.modalTransitionStyle = UIModalTransitionStyle.CoverVerticalself.presentVIEwController(vc,animated: true,completion: nil)

这是我的NewVIEwController,我尝试接收值.但最终仍然是零.

import UIKitclass NewVIEwController: UIVIEwController {    var createAccountDelegate:AccountCreationDelegate!    var teststring:Nsstring!    overrIDe func vIEwDIDLoad() {        super.vIEwDIDLoad()    }

我错误地发送了这些值吗？

解决方法 您正在使用此行创建NewVIEwController的新实例

let newVIEwController:NewVIEwController = NewVIEwController()

而是将变量和委托分配给已从StoryBoard实例化的vc

var storyboard : UIStoryboard = UIStoryboard(name: Storyboardname,bundle: nil)// It is instance of  `NewVIEwController` from storyboard var vc : NewVIEwController = storyboard.instantiateVIEwControllerWithIDentifIEr(NewVIEwController) as NewVIEwController// Pass delegate and variable to vc which is NewVIEwControllervc.createAccountDelegate = selfvc.teststring = "hello"vc.TransitioningDelegate = selfvc.modalTransitionStyle = UIModalTransitionStyle.CoverVerticalself.presentVIEwController(vc,completion: nil)
