    <p>Ok so this is kind of a strange issue, but I have got two scrollViews that each have a nested imageView so as to allow for panning and zooming of an image. The tow scrollView/imageView combo's are showing up just great, and because the image is bigger than my scrollView size, I can pan just great. Here is my viewDidLoad:</p> <pre><code>-(void) viewDidLoad { // set the image to be displayed, pic your own image here imageView = [[MyImage alloc] initWithImage: [UIImage imageNamed: @"newBackground.png"]]; // yes we want to allow user interaction [imageView setUserInteractionEnabled:YES]; // set the instance of our myScrollView to use the main screen scrollView = [[MyScroll alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; // turn on scrolling [scrollView setScrollEnabled: YES]; // set the content size to the size of the image [scrollView setContentSize: imageView.image.size]; // add the instance of our myImageView class to the content view [scrollView addSubview: imageView]; // flush the item [imageView release]; // set max zoom to what suits you [scrollView setMaximumZoomScale:1.0f]; // set min zoom to what suits you [scrollView setMinimumZoomScale:0.25f]; // set the delegate [scrollView setDelegate: self]; // scroll a portion of image into view (my image is very big) :) //[scrollView scrollRectToVisible:CGRectMake(100, 100, 320, 440) animated:NO]; // yes to autoresize scrollView.autoresizesSubviews = YES; // set the mask scrollView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); // set the view //self.view =scrollView; [scrollView setFrame:CGRectMake(0, 0, 320, 230)]; [self.view addSubview:scrollView]; imageView1 = [[MyImage alloc] initWithImage: [UIImage imageNamed: @"newBackground.png"]]; // yes we want to allow user interaction [imageView1 setUserInteractionEnabled:YES]; // set the instance of our myScrollView to use the main screen scrollView1 = [[MyScroll alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; // turn on scrolling [scrollView1 setScrollEnabled: YES]; // set the content size to the size of the image [scrollView1 setContentSize: imageView1.image.size]; // add the instance of our myImageView class to the content view [scrollView1 addSubview: imageView1]; // flush the item [imageView1 release]; // set max zoom to what suits you [scrollView1 setMaximumZoomScale:1.0f]; // set min zoom to what suits you [scrollView1 setMinimumZoomScale:0.25f]; // set the delegate [scrollView1 setDelegate: self]; // scroll a portion of image into view (my image is very big) :) //[scrollView scrollRectToVisible:CGRectMake(100, 100, 320, 440) animated:NO]; // yes to autoresize scrollView1.autoresizesSubviews = YES; // set the mask scrollView1.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); // set the view //self.view =scrollView; [scrollView1 setFrame:CGRectMake(0,240,320,230)]; [self.view addSubview:scrollView1]; //[[self view] addSubview:scrollView]; </code></pre> <p>}</p> <p>No as for zooming, when I pinch to zoom on the FIRST scrollView/imageView pair, it works beautifully, no problems whatsoever. It zooms and pans no problem. BUT when I pinch to zoom my second scrollView, it pans the image of the SECOND, and zooms the image of the FIRST. SO my SECOND scrollView zooms the FIRST's image. Huh? I have no idea why that would be happening.</p> <p>All I want is to have to separate images viewed that can be independently panned and zoomed.</p> <p>Any thoughts as to what might be happening?</p> <p>Thanks!</p>

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.
