Is there a good component for showing a text log on screen in an iPhone app?

Question

I want to have a screen in my app that shows real-time log information - e.g. a scrolling list of textual strings. Previously I've seen people just use a textview and append new log entries to the list - it seems this may be not so efficient, especially when the list becomes long. Is there any sample code out there that can efficiently show real-time text log information? Or does everyone just write their own using a tableview?

Thanks

Answer 1

If you're building your own, perhaps you could use a deque of UITextView instances, adding to the end of the queue and removing from the front, only buffering a constant number of instances.

You could perhaps feed the deque to a UIView that contains the text views as subviews, with various offsets set based on how many lines your application is displaying at one time.

Answer 2

UITableView would be the way to go here, and using the deque idea Alex mentioned above, just call insertRowsAtIndexPaths:withRowAnimation: and deleteRowsAtIndexPaths:withRowAnimation: as you push/pop log entries onto your deque.
