    <p>I'm using a NSTimer in a NSObject class (Timer), that fires a method, that increments a variable and fires a method in a View Controller (InfoViewController). (Confused ;-D )</p> <p>Everything shows up on the screen and and the timer is started correctly. The variable f.hunger updates and shows the correct value (when using printf("%f", f.hunger) ) but the UIProgress bar doesn't update itself. f.hunger's starting value is 1.</p> <p>If anyone can help me, point out where I've made an obvious mistake or got a suggestion it would be most appreciated as it's been doing my head in for a good few hours now. I've added some sample code below to show what I'm doing a bit more clearly.</p> <p>Cheers everyone. :-D</p> <p>Timers Class</p> <pre><code>- (void)startHungerTimer { if(hungerTimer.isValid == NO) { infoVC = [[InfoViewController alloc] init]; self.hungerTimer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(incrementHungerTimer:) userInfo:nil repeats:YES]; } } - (void)incrementHungerTimer:(NSTimer *)aTimer { f.hunger -= 0.01; [infoVC updateHungerProgress]; } </code></pre> <p>Info View Controller</p> <pre><code>- (void)updateHungerProgress { Functions *f = [Functions sharedFunctions]; hungerBar.progress = f.hunger; } - (void)loadView { hungerBar = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleDefault]; [hungerBar setFrame:CGRectMake(17.0, 30.0, 160.0, 10.0)]; hungerBar.progress = f.hunger; [bView addSubview:hungerBar]; [hungerBar release]; } </code></pre>

    1. COHave you confirmed hungerBar.progress is correctly initialized / hooked up through IB (if you used IB)?

    2. COYeah I've initialized hungerBar above in -(void)loadView{}. Sorry should have mentioned that. :-)

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.
