Setting the "plannedFor" attribute of a work item

Hi,
I wrote a function that updates the Category ("Filed Against") of a work item from a String.
I would like to do the same for the "Planned for" field but I can't seem to find a way to get an IIterationHandle object.
I will really appreciate some help with this.

Thanks!

The Category function looks like this:

public void setCategory(String categoryName) throws RTCException {

		ITeamRepository teamrepo = (ITeamRepository) rtc_item.getOrigin();



		IWorkItemClient workItemClient = (IWorkItemClient) teamrepo.getClientLibrary(IWorkItemClient.class);



		List<String> path= Arrays.asList(categoryName.split("/"));

		ICategoryHandle category;

		try {

			category = workItemClient.findCategoryByNamePath(projectArea, path, null);



			if (category == null) {

				throw new RTCException("Category Not Found");

			}



			rtc_item.setCategory(category);		

		} catch (TeamRepositoryException e) {

			throw new RTCException(e.getMessage());

		}

	}
