Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
OK - I have a loop that needs to repeatedly call setBackgroundColor on a UIImageView using a series of different periods. If you were to imaging a morse code flasher, you'd be along the same lines with the dots and dashes being different lengths, along with a predefined "gap" in the middle. The problem is the loop doesn't give the view time to actually process the call - so I'm scratching my head over which way to do this.
Two ways I've come up with is pre-scheduling an NSTimer to fire at all the future points, or to use an NSThread to fire over and over and then switch the view...
Both ways appear in my head to be a bit complicated - but bare in mind the 20 years of VB "training" I had before starting with Objective-C a few years back.
