Retrieve image from parse - ios

Question

I would want to to use two carousel using the icarousel to display images from parse. This is my the code when retrieving images from the document folder.
- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
//return the total number of items in the carousel
if (carousel == carousel1)
{
return [items1 count];
PFQuery *query = [PFQuery queryWithClassName:#"TopsC"];
PFUser *user = [PFUser currentUser];
[query whereKey:#"user" equalTo:user];
[query orderByAscending:#"createdAt"];
}
else
{
return [items2 count];
PFQuery *query = [PFQuery queryWithClassName:#"BottomC"];
PFUser *user = [PFUser currentUser];
[query whereKey:#"user" equalTo:user];
[query orderByAscending:#"createdAt"];
}
}
ITEMS
- (void)awakeFromNib
{
NSLog(#"ooooo");
//set up data sources
self.items1 = [NSMutableArray array];
for (int i = 0; i < 100; i++)
{
[items1 addObject:[NSNumber numberWithInt:i]];
}
self.items2 = [NSMutableArray array];
for (int i = 65; i < 65 + 58; i++)
{
[items2 addObject:[NSString stringWithFormat:#"%c", i]];
}
}
However I don't nothing is displayed for the carousel. Why is it not importing photo from parse?

Answer 1

First; the query code never gets run, as you start with returning [items1 count];
Anything included after the return statement is ignored.
Second; There is nothing in the code you provided that return anything from Parse. Your data sources (items1/items2) get populated with numbers and strings in your awakeFromNib, but there is no contact with parse in this code. Except the queries for Topsc and BottomC, which is never executed. And even if they DID get executed, you don't trigger the queries. You just set them up.
So, to answer your question: you don't query parse for any images, and that's why the carousels don't get any images.
