Ideas for programming a scrolling tag cloud on iPhone?
Given a collection of Word objects, I want to display a scrollable tag cloud similar to what is shown below. My Word class has properties for Name and Rank from which I will determine sorting and weighting of the fonts. Each word should be a selectable object (for invoking some event). Since the collection can contain thousands of objects, I only need to manage words that are currently presented in the view (i.e., as they scroll off the bottom or top of the screen, I no longer care about them).
How would you approach this?
I ended up using a UITableView with a custom UITableViewCell containing an array of custom labels. With proper use of lazy loading and background processing, it is plenty fast. I'll go ahead and mark mine as the accepted answer, but I do appreciate all of the responses.
