    <p>I've basically reached the same conclusions as @Louis, but also made some comments within the code as to what I removed and why.</p> <pre><code>- (void)loadView { [super loadView]; CGRect theRect = CGRectMake(0, 0, 320, 480); UIView *view = [[UIView alloc] initWithFrame:theRect]; [view setBackgroundColor:[UIColor purpleColor] ]; self.view = view; [view release]; UIView *pippo = [[UIView alloc] initWithFrame:theRect]; [pippo setBackgroundColor:[UIColor redColor]]; [self.view addSubview:pippo]; [pippo release]; [self performSelector:@selector(scrollAdd:) withObject:nil afterDelay:2.0f]; } -(void)scrollAdd:(id)o { CGRect theRect = CGRectMake(0, 0, 320, 480); int numero = 1; scroll = [[UIScrollView alloc] initWithFrame:theRect]; [scroll setContentSize:CGSizeMake( 320*numero,1)]; [scroll setScrollEnabled:YES]; // img is already autoreleased, you're releasing again down below // --- UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"koala1b" ofType:@"jpg"]]; UIImageView *v2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"koala1b.jpg"]]; v2.frame = theRect; //--- [v2 setImage:img]; [scroll addSubview:v2]; [v2 release]; [self.view addSubview:scroll]; // NO !; img is autoreleased from imageWithContentsOfFile //--- [img release]; [self performSelector:@selector(scrollRemove:) withObject:nil afterDelay:2.0f]; } -(void)scrollRemove:(id)o { //--- UIImageView *theV = [[scroll subviews] objectAtIndex:0]; [scroll removeFromSuperview]; // you don't own theV because you didn't create it here, or send it a retain.

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).
