    <p>I'm trying to build "slot machine" game using UIPickerView. I populate it using UIImageView. Problem is that, random images in picker view disappear after every spin, and randomly shows again. It happens on device with ios 5.1.1, but on device with ios4.2.1 and simulator it works perfectly. Right now I'm using <a href="http://www.maddyhome.com/forums/viewtopic.php?f=12&amp;t=32" rel="nofollow">CircularPickerView</a> but before I used UIPickerView and problem was the same. Here's screenshot: <a href="http://axgrzesiek.w.interii.pl/licznik.PNG" rel="nofollow">http://axgrzesiek.w.interii.pl/licznik.PNG</a></p> <p>GraViewController.h:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "CircularPickerView.h" @interface GraViewController : UIViewController &lt;UIPickerViewDataSource, UIPickerViewDelegate&gt; { CircularPickerView *picker; UILabel *winLabel; NSArray *column1; NSArray *column2; NSArray *column3; } @property(nonatomic, retain) IBOutlet CircularPickerView *picker; @property(nonatomic, retain) IBOutlet UILabel *winLabel; @property(nonatomic, retain) NSArray *column1; @property(nonatomic, retain) NSArray *column2; @property(nonatomic, retain) NSArray *column3; -(IBAction)spin; @end </code></pre> <p>GraViewController.m:</p> <pre><code>- (IBAction)spin { BOOL win = NO; int numInRow = 1; int lastVal = -1; for (int i = 0; i &lt; 3; i++) { int newValue = arc4random() % [self.column1 count]; if (newValue == lastVal) numInRow++; else numInRow = 1; lastVal = newValue; //if (newValue &lt; [self.column1 count] || newValue &gt;= (2 * [self.column1 count]) ) { //newValue = newValue % [self.column1 count]; //newValue += [self.column1 count]; [self.picker selectRow:newValue inComponent:i animated:YES]; //} NSLog(@"kol:%d %d",i, newValue); //[picker reloadComponent:i]; if (numInRow &gt;= 3) win = YES; } if (win) winLabel.text = @"WIN!"; else winLabel.text = @""; //[picker reloadAllComponents]; //[self performSelector:@selector(moveIntoPosition) withObject:nil afterDelay:0.5f]; - (void)viewDidLoad { NSString *title=@"Gra"; [self setTitle:title]; UIImage *seven = [UIImage imageNamed:@"jeden.png"]; UIImage *bar = [UIImage imageNamed:@"dwa.png"]; UIImage *crown = [UIImage imageNamed:@"trzy.png"]; UIImage *cherry = [UIImage imageNamed:@"cztery.png"]; UIImage *lemon = [UIImage imageNamed:@"piec.png"]; UIImage *apple = [UIImage imageNamed:@"szesc.png"]; for (int i = 1; i &lt;= 3; i++) { UIImageView *sevenView = [[UIImageView alloc] initWithImage:seven]; UIImageView *barView = [[UIImageView alloc] initWithImage:bar]; UIImageView *crownView = [[UIImageView alloc] initWithImage:crown]; UIImageView *cherryView = [[UIImageView alloc] initWithImage:cherry]; UIImageView *lemonView = [[UIImageView alloc] initWithImage:lemon]; UIImageView *appleView = [[UIImageView alloc] initWithImage:apple]; NSArray *imageViewArray = [[NSArray alloc] initWithObjects: sevenView, barView, crownView, cherryView, lemonView, appleView, nil]; NSString *fieldName = [[NSString alloc] initWithFormat:@"column%d", i]; [self setValue:imageViewArray forKey:fieldName]; //column1=[[NSArray alloc]initWithArray:imageViewArray]; //column2=[[NSArray alloc]initWithArray:imageViewArray]; //column3=[[NSArray alloc]initWithArray:imageViewArray]; [fieldName release]; [imageViewArray release]; [sevenView release]; [barView release]; [crownView release]; [cherryView release]; [lemonView release]; [appleView release]; //[picker selectRow: [self.column1 count] * (48 / 2) inComponent:i-1 animated:NO]; } } - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view { NSString *arrayName = [[NSString alloc] initWithFormat:@"column%d", component+1]; NSArray *array = [self valueForKey:arrayName]; [arrayName release]; return [array objectAtIndex:row]; } </code></pre>

Guidance
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).
