Have you considered creating a Quicktime movie in code which displays
the words in the way you want?

I'm working on a Karaoke-like application. I need to print out to
the screen text lines at a given time, and then, paint each word at
a given time. I keep thinking on an elegant way to do such that,
and, i hace to tell, i am afraid, i have not get it right :(.
Here's what i am doing (in pseudocode to keep things simple)
First, i store the time the line is supposed to show on the screen,
the time it is supposed to disappear from the screen, and an array
with the words and the time each word is supposed to be painted. All
times are stored as seconds.
When the application boot, i set and NSTimer to the amount of time i
need to wait for the first line to appear on screen. When time
elapsed, NStimer calls a function where i build UILabels for each
word, insert them in the main UIView. Once the UIView is packed with
all the UILabels, i fire a new loop to walk the UILabels array and
paint the words when needed.
Specifically, i am wondering if there is a better way to write words
to a UIView (and keep a handle to paint them at a given time). Does
anyone get a better algorithm?
best regards
