Swift 2-如何将UIImage分割到另一个自定义类并显示它？

如何将图像传输到另一个视图控制器？例如，此代码通过使用照相机功能拍摄照片，用户确认图像并将其显示在图像视图中，或者可以从“多媒体资料”中进行选择，一旦选择了图像，我如何将其转换为另一个自定义类

以下是ViewController.swift中的代码

@IBAction func btnImagePicker1Clicked(sender: AnyObject)
    {

        let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)

        let cameraAction = UIAlertAction(title: "Camera", style: UIAlertActionStyle.Default)
            {
                UIAlertAction in
                self.openCamera()

        }
        let gallaryAction = UIAlertAction(title: "Gallery", style: UIAlertActionStyle.Default)
            {
                UIAlertAction in
                self.openGallary()
        }
        let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel)
            {
                UIAlertAction in

        }
        // Add the actions
        SKIP2.hidden = true
        BUTTON2.hidden = false
        picker?.delegate = self
        alert.addAction(cameraAction)
        alert.addAction(gallaryAction)
        alert.addAction(cancelAction)
        // Present the controller
        if UIDevice.currentDevice().userInterfaceIdiom == .Phone
        {
            self.presentViewController(alert, animated: true, completion: nil)
        }
        else
        {
            popover=UIPopoverController(contentViewController: alert)
            popover!.presentPopoverFromRect(btnClickMe.frame, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
        }
    }
    func openCamera1()
    {
        if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera))
        {
            picker!.sourceType = UIImagePickerControllerSourceType.Camera
            self .presentViewController(picker!, animated: true, completion: nil)
        }
        else
        {
            openGallary1()
        }
    }
    func openGallary1()
    {
        picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
        if UIDevice.currentDevice().userInterfaceIdiom == .Phone
        {
            self.presentViewController(picker!, animated: true, completion: nil)
        }
        else
        {
            popover=UIPopoverController(contentViewController: picker!)
            popover!.presentPopoverFromRect(btnClickMe.frame, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
        }
    }
    func imagePickerController1(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
    {
        picker .dismissViewControllerAnimated(true, completion: nil)
        imageView.image=info[UIImagePickerControllerOriginalImage] as? UIImage
    }
    func imagePickerControllerDidCancel1(picker: UIImagePickerController)
    {
        print("picker cancel.")

    }
}

如果你有一个图库，你可以通过集合视图->didSelectItem（）来解决这个问题，当你只想点击一个图像时，你可以在这个图像上放置一个没有文本的按钮，并从button@LucaArchidiacono你能告诉我这是怎么写的吗？我好像不明白干杯的人。
