如何使用Picker Controller访问UIImageView以设置图像

Question

我正在以编程方式在UITableViewCell内的UIImageView中添加一个按钮。但是，如何访问原始imageView，以便将所选图像设置为UIImageView？

我的代码：

  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = theTableView.dequeueReusableCellWithIdentifier("SampleCell") as! UITableViewCell

     if indexPath.section == 2 {
        let imageView = UIImageView(frame: CGRectMake(0, 0, 320, 175))
        let button = UIButton(frame: CGRectMake(110, 30, 100, 100))
        let myImage = UIImage(named: "Camera-50.png")

        let touch = UITapGestureRecognizer()
        imageView.addGestureRecognizer(touch)
        imageView.layer.borderWidth = 0.5

        button.setImage(myImage, forState: UIControlState.Normal)
        button.addTarget(self, action: "getImage", forControlEvents: .TouchUpInside)
        cell.addSubview(button)
        cell.addSubview(imageView)
    }

    return cell
}



func getImage() {


    let picker = UIImagePickerController()
    picker.allowsEditing = true
    picker.delegate = self

    presentViewController(picker, animated: true, completion: nil)
}

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

    //need to access imageView to set image

}
