Why is the UITableViewController numberOfRowsInSections called before the init method?

Why is the UITableViewController numberOfRowsInSections called before the
init method?

My UITableViewController won't load the information that I have downloaded
from Parse. I know that the link is working because when I ask it to print
out the PFQuery, I get the results I want. However, my problem is that the
method numberOfRowsInSection is called before the init method. I'm not
really sure how to download my data before the init method.
Here is my .m file
@implementation PicklerTable
@synthesize picklersArray;
- (id) init
{
// Call the cuperclass's designated init
self = [super initWithStyle:UITableViewStyleGrouped];
if(self){
// Insert initial data here
PFQuery *picklerQuery = [PFQuery queryWithClassName:@"Picklers"];
[picklerQuery findObjectsInBackgroundWithBlock:^(NSArray *objects,
NSError *error) {
if (!error) {
picklersArray = [[NSArray alloc] initWithArray:objects];
}
}];
}
return self;
}
-(id) initWithStyle:(UITableViewStyle)style
{
return [self init];
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return picklersArray.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:@"UITableViewCell"];
PFObject *picklerObject = [picklersArray objectAtIndex:indexPath.row];
[[cell textLabel] setText:[picklerObject objectForKey:@"title"]];
return cell;
}
I put a breakpoint in the numberOfRowsInSection method and typed bt into
the console. This was my output:
