I need to view the facebook newsfeeds in my UITableView. I send an asynchronous request to the server and I have obtained the list of newsfeeds. The problem is that i do not obtain, for each feed, the size of the image, and so I must send another asynchronous request to the server nested to previous asynchronous request. This code is very low efficent because I must reload my UITableView repeatedly (see my code).
I need get the image size so as set the height of the UITableCell and the dimension of UIImageView inside the cell.
Any idea to solve my problem ?
Below my code:
-(void)loadData{ //self.tableView.rowHeight = UITableViewAutomaticDimension; screenRect = [[UIScreen mainScreen] bounds]; screenWidth = screenRect.size.width; screenHeight = screenRect.size.height; self.imgDic=[[NSMutableDictionary alloc]init]; self.desArr=[[NSMutableArray alloc]init]; self.mexArr=[[NSMutableArray alloc]init]; self.udidArr=[[NSMutableArray alloc]init]; [FBRequestConnection startWithGraphPath:@"/guide/feed" completionHandler:^(FBRequestConnection *connection,id result,NSError *error){ NSDictionary *data = [result objectForKey:@"data"]; for(NSDictionary *dic in data) { if([dic objectForKey:@"description"]==nil){ [self.desArr addObject:@""]; }else{ [self.desArr addObject:[dic objectForKey:@"description"]]; } if([dic objectForKey:@"object_id"]==nil){ [self.udidArr addObject:@""]; }else{ [self.udidArr addObject:[dic objectForKey:@"object_id"]]; [FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"/%@",[dic objectForKey:@"object_id"]] completionHandler:^(FBRequestConnection *connection,id result,NSError *error) { [self.imgDic setObject:[result objectForKey:@"images"] forKey:[result objectForKey:@"id"]]; //NSLog(@"%@",[result objectForKey:@"id"]); //NSLog(@"%@",[result objectForKey:@"images"]); [self.tableView reloadData]; }]; } if([dic objectForKey:@"message"]==nil){ [self.mexArr addObject:@""]; }else{ [self.mexArr addObject:[dic objectForKey:@"message"]]; } } [self.tableView reloadData]; }];}- (void)viewDidLoad { [super viewDidLoad]; [self loadData];}
