performselectorinBackground is now working

In a view I am showing images which i am fetching from coredata, The
images i am showing using caroseul classes. In the same view i have
facebook button which will navigate me to another screen. When i am
clicking the Facebook button then the action is not getting performed,
after the images are loaded only the next screen is coming, the button
action is not getting called as soon as i click on it.
In viewDidLoad I have called:
[self performSelectorInBackground:@selector(popularImages) withObject:nil];
The popularImages method :
- (void)popularImages
{
NSFetchRequest *request = [[NSFetchRequest alloc]
initWithEntityName:@"Deals"];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ispopular
== 1"];
[request setPredicate:predicate];
NSLog(@"popular Hypes called");
[self.managedObjectContext executeFetchRequest:request
returnManagedObjectIDs:NO onSuccess:^(NSArray *deals) {
deals123 = [[NSMutableArray alloc] initWithArray:deals];
ij = 1;
for (Deals *deals in deals123) {
customizedMessage = [deals valueForKeyPath:@"txtmsgrec"];
dealIdString = [deals valueForKeyPath:@"dealsId"];
