Does anyone know how to reload/refresh a UICollectionView while the collection view is being displayed? Basically I'm looking for something similar to the standard reloadData method for a UITableview.
You can just call
[self.myCollectionView reloadData]; Individual sections and items can also be reloaded:
[self.myCollectionView reloadSections:indexSet]; [self.myCollectionView reloadItemsAtIndexPaths:arrayOfIndexPaths];
