照片控制器是

import Foundation
import UIKit
class PhotoController:UIViewController,UINavigationControllerDelegate,UIImagePickerControllerDelegate{
    @IBOutlet weak var myImageView: UIImageView!
    @IBAction func PhotoSelect(_ sender: Any) {
            }

    @IBAction func PhotoSend(_ sender: Any) {
        let myPickerController = UIImagePickerController()
        myPickerController.delegate = self;
        myPickerController.sourceType = UIImagePickerControllerSourceType.photoLibrary

        self.present(myPickerController, animated: true, completion: nil)

    }
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])

    {
        myImageView.image = info[UIImagePickerControllerOriginalImage] as? UIImage

        self.dismiss(animated: true, completion: nil)

    }
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

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

插座就是插座

我阅读了为什么会发生此错误消息。它说当“插座”错误时，会发生此错误。但我不知道如何解决此问题。我看到 PhotoSelect&PhotoSend 的插座有！，但我不明白这是什么意思。我该怎么办？

特里斯坦·比顿

问题是两个插座PhotoSelect和PhotoSend。您可能不小心将这些创建为@IBOutlet、删除了它们并重新创建为@IBAction。

看看他们!旁边有一个。这意味着这些插座不再连接。所以当你运行你的应用程序时，你的故事板在你的视图控制器中找不到这些插座，所以它崩溃了。

您需要通过单击删除这些插座x。
