title: iPhone forcing redraw (Objective C++)
body: <p>I'm coding this app in objective c++ (.mm file), and I'm having some difficulties. I have this loop, and every 10 seconds it runs and updates some numbers which I output to label fields on the display. The problem is that, although the loop works properly with the 10 second pause between runs (which I implemented with pthreads and a sleep function in an linked C++ file), the display will not refresh to show these new values. Is there a way I can force it to refresh/redraw at the end of every loop?</p>
