    <p>I have two-views app for iPhone. On first one I call code that does this every second with NSTimer:</p> <ol> <li>update variables</li> <li>make sound</li> <li>update label</li> <li>update image position</li> </ol> <p>When I start app - everything works perfect. When I go to other view and then go back to first screen - 1 and 2 works fine, but 3 and 4 resets and does not work at all. </p> <p>What could be the problem?</p> <p>Looks like it loses "hooks" to elements... </p> <pre><code>-(void)countup { DeccelFloat += 0.4; SpeedFloat += 5/(DeccelFloat); SpeedInt = lroundf(SpeedFloat); speed.text = [NSString stringWithFormat:@"%i", SpeedInt]; imageview.center = CGPointMake(imageview.center.x, imageview.center.y+3); if (imageview.center.y &lt; 280) { imageview.alpha = 1; if (SpeedFloat &gt; MaxSpeedValue) { [self playalarm]; }else{ [self playbeep]; } } if ((imageview.center.y &gt;= 280) &amp;&amp; (imageview.center.y &lt; 283)) { if (SpeedFloat &gt; MaxSpeedValue) { [self playshot]; }else{ [self playbeepbeep]; } } if ((imageview.center.y &gt;= 280) &amp;&amp; (imageview.center.y &lt; 350)) { imageview.alpha = 0.5-(0.5/70)*(imageview.center.y - 280); } if (imageview.center.y &gt;= 350) { imageview.alpha = 0; imageview.center = CGPointMake(imageview.center.x, 180); } } </code></pre> <p>And here is my timer:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; MaxSpeedValue = 60; NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults]; NSNumber *maxspeedsetttings = nil; NSNumber *blinkingsetttings = nil; NSNumber *startedsetttings = nil; if (standardUserDefaults) { maxspeedsetttings = [standardUserDefaults objectForKey:@"maxspeedsetttings"]; blinkingsetttings = [standardUserDefaults objectForKey:@"blinkingsetttings"]; startedsetttings = [standardUserDefaults objectForKey:@"startedsetttings"]; } MaxSpeedDef = [maxspeedsetttings intValue]; if (MaxSpeedDef == 1) { maxspeed.text = [NSString stringWithFormat:@"%i", MaxSpeedValue]; }else{ maxspeed.alpha = 0; maxspeedlabel.alpha = 0; } imageview.animationImages = [NSArray arrayWithObjects: [UIImage imageNamed:@"0.png"], [UIImage imageNamed:@"5.png"], [UIImage imageNamed:@"10.png"], nil]; imageview.animationDuration = 1; imageview.animationRepeatCount = 0; BlinkingDef = [blinkingsetttings intValue]; if (BlinkingDef == 1) { [imageview startAnimating]; }else{ [imageview stopAnimating]; } [self.view addSubview:imageview]; StartedDef = [startedsetttings intValue]; if (StartedDef == 0) { SpeedFloat = 0; DeccelFloat = 0; timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countup) userInfo:nil repeats:YES]; StartedDef = 1; if (standardUserDefaults) { [standardUserDefaults setObject:[NSNumber numberWithInt:StartedDef] forKey:@"startedsetttings"]; [standardUserDefaults synchronize]; } } } </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
