Retrieve image from user class in Parse

Question

I am trying to retrieve an image from parse.com, but can't figure out how!

I used this code to save image to the user class in parse.com:

NSData *imageData = UIImageJPEGRepresentation(imageView.image, 1.0);
imageFile = [PFFile fileWithName:@"profilePic" data:imageData];

PFUser *user = [PFUser currentUser];
[user setObject:imageFile forKey:@"imageFile"];

[user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
    if (succeeded) {
        NSLog(@"saved");
    }
}];

Now I want to retrieve the same image back and se it in the imageView, how can I do that?

Answer 1

Check getDataInBackgroundWithBlock

PFUser *user = [PFUser currentUser];
PFFile *userImageFile = user[@"imageFile"];
[userImageFile getDataInBackgroundWithBlock:^(NSData *imageData, NSError *error) {
    if (!error) {
        UIImage *image = [UIImage imageWithData:imageData];
    }
}];
