PhotoController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.
}
}
奥特莱斯是 outlet
我读了为什么会出现此错误消息。它说当“Outlet”出错时，会发生这种错误。但我不知道如何解决这个问题。我看到PhotoSelect和PhotoSend的出口了！，但我无法理解这个意思。我该怎么办？
答案 0 :(得分：-1)
问题在于两个网点PhotoSelect和PhotoSend。您可能不小心将其创建为@IBOutlet，删除了它们并将其重新创建为@IBAction。
了解他们旁边是否有!。这意味着这些插座不再连接。因此，当您运行app时，您的故事板无法在视图控制器中找到这些插座，因此它会崩溃。
您需要点击x。
