Parse.com with iOS App and Objective-C code

Question

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?

no one has noticed this problem with parse.com ?? there are ways to figure out what's going on? — kAiN

PFQuery *query = [PFUser query]; replace this with PFQuery *query = [PFQuery queryWithClassName:@"_User"]; this might help and get it in backgound like [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { }}]; — Ajay Gabani

Rory, are you allowing Xcode access to the Internet when it starts up? I know it's basic but please confirm connectivity. — Tommie C.

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.

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
