AFNetworking request returns nil - ios

Question

i have a request which returns information from a php web service. I'm having trouble adding this to a array which can be used in my UICollectionView. It seems like whatever i do i cant return the data. I think it is because i'm returning the array before i've added any objects. I've tried placing the NSLog several places, but without luck. What am i doing wrong?
When i place this NSLog(#"%d", imagesArray.count); beyond the request it returns 0.
ViewDidAppear:
-(void)viewDidAppear:(BOOL)animated {
imagesArray = [[NSMutableArray alloc] init];
[self getImages];
}
getImages method:
-(void)getImages {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager GET:#"http://URL.COM" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseObject options:kNilOptions error:nil];
NSString *theTitle = [[json objectForKey:#"response"] valueForKey:#"title"];
NSString *theUrl = [[json objectForKey:#"response"] valueForKey:#"imageUrl"];
[imagesArray addObject:[[NSMutableDictionary alloc] initWithObjectsAndKeys:
theTitle, #"title",
theUrl, #"url",
nil]];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
NSLog(#"%d", imagesArray.count);
}

AFNetworking is Asynchronous, you have to place the log inside the success block. Otherwise the array will always be empty.
One good solution would be to pass a block to your getImages function like that
-(void) getImages:(void (^)(BOOL result))callback {
// your code here then you call callback(YES or NO) inside your success or failure block.
}
[self getImages:^(BOOL result){
if(result)
//we got the images, we can now display them etc.
}];
