    Implement heightForRowAtIndexPath to calculate the right height. Then in the code for your button, force the table to reevaluate each cell’s height with beginUpdates plus endUpdates:

    [self.tableView beginUpdates];
[self.tableView endUpdates];

    Changes to the tableview cells’ heights will automatically be calculated with heightForRowAtIndexPath and the changes will be animated too.

    In fact, instead of a button on your cell that does this, you might even just make selecting the cell do this in didSelectRowAtIndexPath.
