Thanks! I've tried doing this, but am having some issues. When I switch the datasource and call reloadData, I see the follow trace in the debugger: #0 0x93fa3688 in objc_msgSend #1 0x30bed381 in -[UITableViewRowData(UITableViewRowDataPrivate) _updateNumSections] #2 0x30bed6dc in -[UITableViewRowData invalidateAllSections] #3 0x30a9ca9f in -[UITableView(_UITableViewPrivate) _updateRowData] #4 0x30aa1885 in -[UITableView noteNumberOfRowsChanged] #5 0x30aa65eb in -[UITableView reloadData] #6 0x000127ee in -[ProfileViewController tabBar:tabSelected:] at ProfileViewController.m:143 I'm not sure if I'm doing something wrong or not? Do I need to invalidate the datasource first or is there a different way to change it? Here is the sample code that I'm using. #import <Three20/Three20.h> @interface ProfileViewController: TTTableViewController <TTTabBarDelegate> { TTTabBar* _tabBar; } @end #import "ProfileViewController.h" static NSString* kLoremIpsum = @"Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do\ eiusmod tempor incididunt ut labore et dolore magna aliqua.
