我一直在迅速3中收到“信號1：SIGABRT”，但我不知道該如何解決

Question

我檢查了所有連接， 沒有一個斷開。 我已經重新連接了所有人，並檢查了所有內容，但我一直收到此錯誤。 它出現在App Delegate的第一行中，我不知道為什么。 這是代碼。

class DetailsViewController: UIViewController, SFSafariViewControllerDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate{

    let imagePicker = UIImagePickerController()


    @IBOutlet weak var MITImageView: UIImageView!
    @IBOutlet weak var StanfordImageView: UIImageView!
    @IBOutlet weak var HarvardImageView: UIImageView!

    @IBAction func MITSafariViewControllerButton(_ sender: UIButton) {
        let url = NSURL(string: MITUrl)!
        let svc = SFSafariViewController(url: url as URL)
        present(svc, animated: true, completion: nil)
    }

    @IBAction func StanfordSafariViewControllerButton(_ sender: UIButton) {
        let url = NSURL(string: StanfordUrl)!
        let svc = SFSafariViewController(url: url as URL)
        present(svc, animated: true, completion: nil)
    }

    @IBAction func HarvardSafariViewControllerButton(_ sender: UIButton) {
        let url = NSURL(string: HarvardUrl)!
        let svc = SFSafariViewController(url: url as URL)
        present(svc, animated: true, completion: nil)

    }

    @IBAction func imageChangeButton(_ sender: UIButton) {
        imagePickerClass().imagePickerControllerMIT(picker: imagePicker)
    }
    @IBAction func imageChangeButtonStanford(_ sender: UIButton) {
        imagePickerClass().imagePickerControllerStanford(picker: imagePicker)
    }

如果您能幫助我解決這個問題，那將是很好的。

Answer 1

首先要說的是我正在使用Xcode 7.0和IOS 9.0 。 而且我在objective-c也遇到了同樣的問題。 我發現異常原因只是調試我的代碼（基本上是由哪一行負責）。 我將與您分享。 盡管您的問題是swift相關的，但我只是想為signal 1: SIGABRT提供幫助。 可能會對您有幫助。

1.首先在任何行上設置代碼的debug pointer 。 單擊show the break point navigator圖標。

2.單擊create a break point圖標。

3.單擊Add Exception BreakPoint 。

4.右鍵單擊All Exception ，然后單擊Edit BreakPoint 。

5.選擇objective-c作為“例外”的選項。

並運行您的應用程序。 它將帶您到獲得SIGABRT的相應行。
