Parse.com with iOS App and Objective-C code

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. I'm using Xcode 6

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

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]

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

回答1:

Why don't use PFFile instead?

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;
    }];

And for the PFQuery replace that method with this block:

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

or check the class reference here

On the PFImageView:

Try calling – loadInBackground on in. Source

On autocompletion:

This seems to be a bug in Xcode actually. After they have implemented the "nullable" keyword, Xcode seems to be having a hard time auto generating code for the blocks you pass as arguments. That has nothing to do with Parse though.
