I am sharing a video on Facebook using Facebook SDK 3.1.1. I have mentioned the code here. FBRequestConnection *newConnection = [[FBRequestConnection alloc] init]; // for each fbid in the array, we create a request object to fetch // the profile, along with a handler to respond to the results of the request NSString *fbid = @"me"; // create a handler block to handle the results of the request for fbid's profile FBRequestHandler handler = ^(FBRequestConnection *connection, id result, NSError *error) { // output the results of the request [self requestCompleted:connection forFbID:fbid result

You can add UIRefreshControl to UICollectionView (or any UIScrollView for that matter) by adding it to collection's subviews : UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged]; [self.collectionView addSubview:refreshControl]; This doesn't work when collection view layout has UICollectionViewScrollDirectionHorizontal .

For example, if the user clicks on the 13th UICollectionViewCell 's button, then the 13th NSString in the array would become the UILabel 's text. What I have done: I have made my own subclass of UICollectionViewCell for the nib file that I use for
