如何在Swift中使用PFImageView?

问题描述

我尝试将其中的一个拖到情节提要中，但我能找到的只是UIImageView.在我的UIImageView的IBOutlet中，我将其更改为PFImageView，并且收到一条错误消息:使用未声明的类型:'PFImageView'"

I've tried simply dragging one into my storyboard, but there all I can find is UIImageView. In my IBOutlet for the UIImageView, I changed it to a PFImageView, and I get an error saying:"Use of undeclared type: 'PFImageView'"

迅速不存在PFImageViews吗?

Do PFImageViews simply not exist in swift?

推荐答案

您需要确保已安装Parse SDK.您还需要确保在使用的类上导入ParseUI，例如:

You need to ensure that you have the Parse SDK installed.You also need to ensure that you import the ParseUI on the class you are using, for example:

import ParseUI

然后，您可以在Storyboard上选择一个普通的ImageView，转到界面构建器上的Identity Inspector，将其类从UIImageView更改为PFImageView

You can then, on your Storyboard, select a normal ImageView, go to the Identity Inspector on your interface builder, change its class from UIImageView to PFImageView

将其作为代码的常规出口连接，但不要将其作为UIImageView连接，而是确保它是PFImageView，如下所示:

Connect it as an outlet as normal to your code, but instead of connecting as a UIImageView ensure it is a PFImageView, like this:

@IBOutlet weak var imgTestImage :PFImageView!

您现在可以访问PFImageView属性，例如:

You now have access to the PFImageView attributes such as:

let theImage = yourObject.valueForKey("profileImage") as? PFFile
imgTestImage.file = theImage
imgTestImage.loadInBackground()
