问题描述

直到最近，我一直使用Parse.com来管理我的应用程序的数据，而我现在正在处理一个新项目，但是我遇到了一些问题....

until recently, I've always used Parse.com for data management of my app I was now working on a new project and I have some problems ....

P.S.我正在使用Xcode 6

P.S. I'm using Xcode 6

首先出现 PFImageView ，您可以确认吗?在不咨询PFImageView的情况下，如何在我的应用程序中绘制图片?我不明白为什么您不能在我的应用程序PFImageView中使用

First there PFImageView, you can confirm this? at this point without consulting a PFImageView how can I draw a picture in my app? I do not understand why you can not use in my app PFImageView

另外，当我执行查询时，以前(使用键盘上的Enter按钮)出现了查询的自动构建块，但现在我发现了这个

Also when I do a query, previously (using the enter button on the keyboard) appeared the auto-build block of the query but now I find myself this

  PFQuery *query = [PFUser query];
  [query findObjectsInBackgroundWithBlock: (nullable PFArrayResultBlock (nullable) block]

parse.com发生了什么事?我在哪里做错了?有人可以给我帮助吗?

What is happening to parse.com? where am I doing wrong? someone can 'give me help on this?

推荐答案

为什么不使用PFFile?

Why don't use PFFile instead?

要从数据加载图像，您可以执行以下操作:

For loading an image from data you can do like this:

    PFFile *fileImage = your_file;
    [fileImage getDataInBackgroundWithBlock:^(NSData *imageData, NSError *error) {
       UIImage *image = [UIImage imageWithData:imageData];
       yourImageView.image = image;
    }];

对于PFQuery，用以下代码块替换该方法:

And for the PFQuery replace that method with this block:

 [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { }}];
