I'm trying to scroll through images being downloaded from a users online album (like in the facebook iphone app) since i can't load all images into memory, i'm loading 3 at a time (prev,current & next). then removing image(prev-1) & image (next +1) from the uiscroller subviews. my logic works fine in the simulator but fails in the device with this error: [CALayer retain]: message sent to deallocated instance what could be the problem below is my code sample

- (void)scrollViewDidEndDecelerating:(UIScrollView *)_scrollView 

{ pageControlIsChangingPage = NO; CGFloat pageWidth = _scrollView.frame.size.width; int page = floor((_scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;

if (page>1 && page<=(pageControl.numberOfPages-3)) {

[self removeThisView:(page-2)]; [self removeThisView:(page+2)]; }

if(page>0) { NSLog(@"<< PREVIOUS"); [self showPhoto:(page-1)]; }

[self showPhoto:page]; if(page<(pageControl.numberOfPages-1)) { //NSLog(@"NEXT >>"); [self showPhoto:page+1]; NSLog(@"FINISHED LOADING NEXT >>"); } }

-(void) showPhoto:(NSInteger)index

{ CGFloat cx = scrollView.frame.size.width*index; CGFloat cy = 40;

CGRect rect=CGRectMake( 0, 0,320, 480); rect.origin.x = cx; rect.origin.y = cy; AsyncImageView* asyncImage = [[AsyncImageView alloc] initWithFrame:rect]; asyncImage.tag = 999; NSURL *url = [NSURL URLWithString:[pics objectAtIndex:index]];

[asyncImage loadImageFromURL:url place:CGRectMake(150, 190, 30, 30) member:memberid isSlide:@"Yes" picId:[picsIds objectAtIndex:index]];

[scrollView addSubview:asyncImage]; [asyncImage release];

}

-(void) removeThisView:(NSInteger)index

{ if(index<[[scrollView subviews] count] && [[scrollView subviews] objectAtIndex:index]!=nil){ if ([[[scrollView subviews] objectAtIndex:index] isKindOfClass:[AsyncImageView class]] || [[[scrollView subviews] objectAtIndex:index] isKindOfClass:[UIImageView class]]) {

[[[scrollView subviews] objectAtIndex:index] removeFromSuperview]; } }

}

For the record it works OK in the simulator, but not the iphone device itself. any ideas will be appreciated. cheers, fred.
