I have a Table View Controller with cells. I want to update the text that is displayed on the visible UITableViewCells. Is there a way to get a reference to the cells that are currently on the screen?

What you can do is go and ask for the cells at index paths using
- (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath, if they are not nil, you know they are on the screen and you can do what you wish with them. Also if you know the visible rectangle on the screen (which shouldnt be hard to get) you can use tableViews- (NSArray *)indexPathsForRowsInRect:(CGRect)rectand you can get all your visible index paths and usecellForRowin order to get the cells back.As long as this is marked as answer, I stand corrected, like others said you can do
[tableView visibleCells]
