@interface ViewController : UIViewController<UICollectionViewDataSource,UICollectionViewDelegate>
{
NSMutableArray *twitterObjects;
}

@property (strong, nonatomic) IBOutlet UICollectionView *myCollectionView;

Here is my viewController.m

The problem is I get the values in the method twitterAPIcall, I can get the names and image values or strings from the values. But in the (TwitterCustomObject*)createPostFromArray:(NSArray*)postArray method all values are coming up as null.I thought it got added with this line of code in the twitterAPIcall method [twitterObjects addObject:twitterInfo];?
