Delete cell from UICollectionView without reloading from top [closed]

Question

I am using a CollectionView in my ios app. Each collection cell contains a delete button. By clicking the button the cell should be deleted. After deletion, that space will be filled with below cell (I don't wish to reload the CollectionView and start from top again)

How do I delete a particular cell from UICollectionView with autolayout?

Answer 1

UICollectionView will animate and automatically rearrange the cells after deletion.

Delete selected items from collection view

[self.collectionView performBatchUpdates:^{      NSArray *selectedItemsIndexPaths = [self.collectionView indexPathsForSelectedItems];      // Delete the items from the data source.     [self deleteItemsFromDataSourceAtIndexPaths:selectedItemsIndexPaths];      // Now delete the items from the collection view.     [self.collectionView deleteItemsAtIndexPaths:selectedItemsIndexPaths];   } completion:nil];    // This method is for deleting the selected images from the data source array -(void)deleteItemsFromDataSourceAtIndexPaths:(NSArray  *)itemPaths {     NSMutableIndexSet *indexSet = [NSMutableIndexSet indexSet];     for (NSIndexPath *itemPath  in itemPaths) {         [indexSet addIndex:itemPath.row];     }     [self.images removeObjectsAtIndexes:indexSet]; // self.images is my data source  }
