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:
-(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];
}
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.
All I want is to have to separate images viewed that can be independently panned and zoomed.
Any thoughts as to what might be happening?
Thanks!
