ios - Swift 3 "didFinishPickingMediaWithInfo"用于 tableview 单元格内的图像

Question

我在表格 View 中有一个注册表单，用户可以在该注册表单中选择个人资料图片。

如何使用所选图像更新 tableview 单元格中的图像？

我如何允许单元格。在不在 tableview 内的“func imagePickerController()”内？

Click for code

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

if let orginalImage = info[UIImagePickerControllerOriginalImage] as? UIImage {

cell.profileImage.image = orginalImage

}

else { print ("error") }

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

}

只需在 didFinishPickingMediaWithInfo 方法中创建单元文件对象即可。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
    {


        //cell file object
        let cell = tblView.cellForRow(at: IndexPath.init(row: 0, section: 0)) as! ProfileTableViewCell //cell file object

        let imgTemp = info[UIImagePickerControllerOriginalImage] as? UIImage// get image from imagePickerViewController
        cell.imgViewProfile.image = imgTemp
        cell.imgViewProfile.layer.cornerRadius = cell.imgViewProfile.frame.size.width/2 // make image circle
        cell.imgViewProfile.layer.masksToBounds = true
        appDelegate.window?.rootViewController?.dismiss(animated: true, completion: nil)
    }
