我一直在迅速3中收到“信号1：SIGABRT”，但我不知道该如何解决

Question

我检查了所有连接， 没有一个断开。 我已经重新连接了所有人，并检查了所有内容，但我一直收到此错误。 它出现在App Delegate的第一行中，我不知道为什么。 这是代码。

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)
    }

    @IBAction func imageChangeButtonHarvard(_ sender: UIButton) {
        imagePickerClass().imagePickerControllerHarvard(picker: imagePicker)
    }

    var MITUrl = "http://web.mit.edu"
    var StanfordUrl = "http://stanford.edu"
    var HarvardUrl = "http://www.harvard.edu"
    override func viewDidLoad() {
        super.viewDidLoad()
        imagePicker.delegate = self


               var logos = [#imageLiteral(resourceName: "MIT Logo"), #imageLiteral(resourceName: "Stanford Logo"), #imageLiteral(resourceName: "Harvard Logo")]

        var pos1 = Int()
        var pos2 = Int()
        var pos3 = Int()

        pos1 = 0
        pos2 = 1
        pos3 = 2

        self.MITImageView.image = logos[pos1]
        self.StanfordImageView.image = logos[pos2]
        self.HarvardImageView.image = logos[pos3]
        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }



}



class imagePickerClass : DetailsViewController {

    var pos1 = Int()
    var pos2 = Int()
    var pos3 = Int()
    var MITImage = Int()
    var StanfordImage = Int()
    var HarvardImage = Int()



    init (){

            })


    }

            })

        })
    }


    func imagePickerControllerHarvard(picker: UIImagePickerController) {
        imagePicker.dismiss(animated: true, completion: {

            var logos = [#imageLiteral(resourceName: "MIT Logo"), #imageLiteral(resourceName: "Stanford Logo"), #imageLiteral(resourceName: "Harvard Logo"), imageSelected]
            self.MITImageView.image = logos[self.HarvardImage]

            })
        })
    }



}

继承人的错误

class AppDelegate: UIResponder, UIApplicationDelegate,       UIImagePickerControllerDelegate, UINavigationControllerDelegate {

如果您能帮助我解决这个问题，那将是很好的。

Answer 1

首先要说的是我正在使用Xcode 7.0和IOS 9.0 。 而且我在objective-c也遇到了同样的问题。 我发现异常原因只是调试我的代码（基本上是由哪一行负责）。 我将与您分享。 尽管您的问题是swift相关的，但我只是想为signal 1: SIGABRT提供帮助。 可能会对您有帮助。

1.首先在任何行上设置代码的debug pointer 。 单击show the break point navigator图标。

2.单击create a break point图标。

3.单击Add Exception BreakPoint 。

4.右键单击All Exception ，然后单击Edit BreakPoint 。

5.选择objective-c作为“例外”的选项。

并运行您的应用程序。 它将带您到获得SIGABRT的相应行。
