    <p>I'm going to take a whack at an answer here. Because in the comments you clarified what you're trying to do. Something after 5 seconds with no response. What I'm showing here is typically used in opengl apps which all my apps are. But something like it should work for you even if your not in open gl.</p> <p>You need something that runs continuously...</p> <pre><code> - (void) startAnimation { if (!animating) { displayLink = [NSClassFromString(@"CADisplayLink") displayLinkWithTarget:self selector:@selector(drawView)]; [displayLink setFrameInterval:animationFrameInterval]; [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; animating = TRUE; } } - (void)stopAnimation { if (animating) { [displayLink invalidate]; displayLink = nil; animating = FALSE; } } </code></pre> <p>We use this in oepngl apps to run the drawview function every 60th of a second timed with the refresh of the display. I don't see why you couldn't do it. Then in you drawView method check the time at the beginning and take care of any other crap you need to, like advancing pieces in a game or just checking to see how long messages have been up..</p> <pre><code>- (void)drawView { timeThisRound = CFAbsoluteTimeGetCurrent(); </code></pre> <p>And check it against whatever event triggers the start of the 5 seconds. If you're past 5 seconds then do whatever you're going to do instead of waiting any longer for them to tap the button.</p> <p>I have my own messaging system that does this. I can set for any message that comes up if it should go away on it's own after 5 seconds. Or if they tap it, it goes away faster. I use the timeThisRound method (a global property) everywhere to track when NOW is so that I can have timing based things as well as touch based things.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
