    <p>I have an integer variable (<strong>time</strong>) in one view controller whose value I need in another view controller. Here's the code:</p> <p><strong>MediaMeterViewController</strong></p> <pre><code>// TRP - On Touch Down event, start the timer -(IBAction) startTimer { time = 0; // TRP - Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES]; [timer retain]; // TRP - Retain timer so it is not accidentally deallocated } // TRP - Method to update the timer display -(void)updateTimer { time++; // NSLog(@"Seconds: %i ", time); if (NUM_SECONDS == time) [timer invalidate]; } // TRP - On Touch Up Inside event, stop the timer, decide stress level, display results -(IBAction) btn_MediaMeterResults { [timer invalidate]; NSLog(@"Seconds: %i ", time); ResultsViewController *resultsView = [[ResultsViewController alloc] initWithNibName:@"ResultsViewController" bundle:nil]; [self.view addSubview:resultsView.view]; } </code></pre> <p>And in ResultsViewController, I want to process <strong>time</strong> based on its value</p> <p><strong>ResultsViewController</strong></p> <pre><code>- (void)viewDidLoad { if(time &lt; 3) {// Do something} else if ((time &gt; 3) &amp;&amp; (time &lt; 6)) {// Do something else} //etc... [super viewDidLoad]; } </code></pre> <p>I'm kind of unclear on when @property and @synthesize is necessary. Is that the case in this situation? Any help would be greatly appreciated.</p> <p>Thanks! Thomas</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.
