UITableView add cell Animation

by

You can use the following UITableView method:

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

Example with self.dataSource being a mutable array and your table only having 1 section:

[self.dataSource addObject:@"New Item"];
NSIndexPath *newIndexPath = [NSIndexPath indexPathForRow:[self.dataSource count]-1 inSection:0];
[tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade];

Note: Subtracted 1 from datasource count since NSIndexPath is zero indexed.
