如何解除模态segue然后执行push segue到新视图控制器 [英] How can I dismiss a modal segue then perform push segue to new view controller

问题描述

在解雇<$ c $后，我试图从导航控制器执行 push segue c> modal 之前通过导航控制器显示。

I'm trying to perform a push segue from a navigation controller, after dismissing a modal that was previously presented over the navigation controller.

内部模态（ UIViewController ）：

func textFieldShouldReturn(textField: UITextField) -> Bool {
    var searchNav = SearchNavigationController()
    self.dismissViewControllerAnimated(true, completion: {searchNav.goToNextView()})
    return true
}

内部 SearchNavigationController ：

func goToNextView() {
    performSegueWithIdentifier("searchNavigationToNextView", sender: self)
}

问题是，当我点击返回时，我收到此错误：

The issue is that when I hit return, I get this error:

由于未捕获的异常而终止应用程序
'NSInvalidArgumentException'，原因：'Receiver
（）没有带有
标识符的segue'searchNavigationToNextView''

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver () has no segue with identifier 'searchNavigationToNextView''

segue出现在我的故事板中，从 UINavigationController 到下一个视图。

The segue is present in my storyboard, going from the UINavigationController to the next view.

编辑：试过这个，其中_sender在SingleSearchViewcontroller中声明为var _sender = self并且它不起作用。

tried this, where _sender is declared in SingleSearchViewcontroller as var _sender = self and it did not work.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "searchNavigationToSingleSearch" {
            let singleVC = segue.destinationViewController as! SingleSearchViewController

            singleVC._sender = self
        }
    }

推荐答案

将代码更新为，

func textFieldShouldReturn(textField: UITextField) -> Bool {
    var searchNav = SearchNavigationController()
    self.dismissViewControllerAnimated(true, completion: {self.presentingViewController.goToNextView()})
    return true
}
