Question

获取获取请求并从核心数据中获取值。基于值F或M，我想要转向VC。它一直在App Delegate上崩溃。我正在使用标签栏控制器来点击进行计算的VC，然后应该转到适当的VC。

func makeSegue() {

    print("\(meetGenderText.text!)")

    if (meetGenderText.text == "F") {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)

        let vc = storyboard.instantiateViewControllerWithIdentifier("scoreFemale") as! ScoreMeetFemaleVC

        presentViewController(vc, animated: true, completion: nil)

        performSegueWithIdentifier("scoreFemale", sender: nil)

    } else {

        let storyboard = UIStoryboard(name: "Main", bundle: nil)

        let vc = storyboard.instantiateViewControllerWithIdentifier("scoreMale") as! ScoreMeetFemaleVC

        presentViewController(vc, animated: true, completion: nil)

        performSegueWithIdentifier("scoreMale", sender: nil)
    }
}

Answer 1

您不应同时使用presentViewController和performSegueWithIdentifier。如果您想使用performSegueWithIdentifier，请确保故事板中存在segue，并从您UIViewController调用的performSegueWithIdentifier开始。还要确保代码中的标识符与storyboard中的segues标识符匹配。
