如何将图像从 camera/camera 滚动到 chosen/taken 后的新视图?

How to pass an image from camera/camera roll to a new view after it has been chosen/taken?

我已经在我的应用程序中添加了一个相机和照片库,但我想要做的是当一些人选择相机、拍照并选择它时,我希望它能将用户引导到一个新的viewcontroller 并在那里显示图像而不是在按钮所在的当前视图上?

我在 Google 上进行了搜索,但没有在 swift 中找到任何明确的内容,而且由于我不了解 ObjC,所以我不确定我所看到的是否正确!

下面是我当前的代码:

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
}

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


@IBAction func Camera(sender: AnyObject) {

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {
    let imagePicker = UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.Camera;
    imagePicker.allowsEditing = false
    self.presentViewController(imagePicker, animated: true, completion: nil)
    }
}


@IBAction func Images(sender: AnyObject) {

    let imageLoad = UIImagePickerController()
    imageLoad.delegate = self
    imageLoad.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    imageLoad.allowsEditing = false


    self.presentViewController(imageLoad, animated: true, completion: nil)
}


func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image:UIImage, editingInfo: [String : AnyObject]?) {

    self.dismissViewControllerAnimated(true, completion: nil)

}

您只需将图像分配给新的视图控制器:

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image:UIImage, editingInfo: [String : AnyObject]?) {

    self.dismissViewControllerAnimated(true, completion: nil)

    let svc = self.storyboard!.instantiateViewControllerWithIdentifier("imageViewer") as! ImageViewController
    svc.image = image

    self.presentViewController(svc, animated: true, completion: nil)   
}

然后,在 imageViewerController 中:

func viewDidLoad() {
    super.viewDidLoad()

    // Because the self.image is an optional var, you need to unwrap it
    if let image = self.image {
        self.imageView.image = self.image
    }
}

根据上面的回答,你试图将图像设置为图像视图,当你应该尝试将图像设置为图像视图的图像时,所以,它应该是:

func viewDidLoad() {
    super.viewDidLoad()

    // Because the self.image is an optional var, you need to unwrap it
    if let image = self.image {
        self.imageView.image = self.image
    } 
}
