Question

There are 3 cells in a tableview. I need to hide and display the middle cell animated. The third cell will move up to the place of the middle cell, when the middle cell is hidden. And when the middle cell is displayed again, the third cell will move to its original place. Is there any method to achieve it?

Answer 1

You can use

- (void)insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation

and

- (void)deleteRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation

but your dataSource will also need to reflect that changes at the time these calls are made

// delete

NSArray *deleteIndexes = [[NSArray alloc] initWithObjects:[NSIndexPath indexPathForRow:1 inSection:0]];

UITableView *tableView = self.tableView;

[tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:deleteIndexes withRowAnimation:UITableViewRowAnimationFade];
// Any other actions for updating the tableView
[tableView endUpdates];
