    <p>I'm having trouble deallocating a UISCrollView that contains images. There's something wrong with my code, but I cannot understand where.</p> <p>this is a snippet of my code. It basically create a loops adding a uiscrollview with an image and removing. If you run the code with instruments, no memory will be freed. I also add some check for the retainCount, with no luck at all..</p> <p>here's the code</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]; UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"koala1b" ofType:@"jpg"]]; int dd = [img retainCount]; UIImageView *v2 = [[UIImageView alloc] initWithFrame:theRect]; [v2 setImage:img]; [scroll addSubview:v2]; dd = [v2 retainCount]; [v2 release]; dd = [v2 retainCount]; dd = [img retainCount]; [self.view addSubview:scroll]; [img release]; dd = [img retainCount]; [self performSelector:@selector(scrollRemove:) withObject:nil afterDelay:2.0f]; } -(void)scrollRemove:(id)o { int dd = [scroll retainCount]; UIImageView *theV = [[scroll subviews] objectAtIndex:0]; dd = [theV retainCount]; [scroll removeFromSuperview]; dd = [theV retainCount]; [theV release]; dd = [theV retainCount]; dd = [scroll retainCount]; scroll = nil; [self performSelector:@selector(scrollAdd:) withObject:nil afterDelay:2.0f]; } </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.
