    <p>I think you should try to find where you might be doing a [scoreTimer retain], and where you might be invalidating (or releasing) gameTimer more than once (you only need to do the latter, if where you checked the retainCount, was after you had invalidated once). You can't increase the retainCount by calling either of</p> <pre><code>[self gameTimerValidate]; [self scoreTimerValidate]; </code></pre> <p>more than once. You would leak memory, and have two timers firing at the same interval, but you wouldn't have one of those timers have a higher retainCount because of that.</p> <p>If those two instance variables were retained properties, and you were setting them using self.gameTimer = ..., then I can see them getting retained an extra time. But the code I see doesn't explain your problem.</p> <p>Search all instances of those two timers and see what else might be messing with things.</p> <p>One suggestion, you might want to check for nil, like this:</p> <pre><code>- (void) gameTimerValidate { if (gameTimer == nil) gameTimer = [NSTimer scheduledTimerWithTimeInterval:[myGame gIntervalSpeed] target:self selector:@selector(gameTimerInterval:) userInfo:nil repeats:YES]; } - (void) scoreTimerValidate { if (scoreTimer == nil) scoreTimer = [NSTimer scheduledTimerWithTimeInterval:0.02 target:self selector:@selector(scoreTimerInterval:) userInfo:nil repeats:YES]; } - (void) invalidateMyTimers { [gameTimer invalidate], gameTimer = nil; [scoreTimer invalidate], scoreTimer = nil; } </code></pre>

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.
