UITableView add cell Animation

Question

Hi Guys,

Can any one help me out with UITableView animating issue.

By default we have animation for deleting cell and reordering cells in UITableView.

Can we have animated adding cell, if so how to do it.

I have checked out Three20, did not not get how twitter has done the table expand animation under MyProfile>ReTweets.

Want to try it without Three20 frameowrk, using the existing animation in UITableView.

Any help on this guys.

Thanks in advance,

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] inSection:0];
[tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade];
