UIScrollview with multiple images and zoom\pan + setContentOffset = strange behavior

[dany_dev]

Hi to all, i started a project where i need to show more images and allow a zoom on it.

In order to add more images to my view i used 2 scrollView: myScrollViewInt and myScrollViewExt. (myScrollViewInt subview of myScrollViewExt).
I added images to internal scrollview. All work as expected, the problem is when i tried to change page with a button.

Example of the code to go in page 2 (portrait):

-(IBAction) goToPageTwoPortrait{
   CGRect rectWillSee = CGRectMake(768, 0, 768, 1024);
	
   [myScrollViewInt scrollRectToVisible:rectWillSee animated:YES];
	
   //[myScrollViewInt setContentOffset:CGPointMake(768, 0) animated:YES]; //SAME ISSUE using it
}

some variables are hard coded, however my images are 768*1024.

Now what happen?

1) start project
2) zoom in with pinch
3) click button to go page 2
4) vertical pan not work anymore! just horizontal pan of the images!.

1) start project
2) click button to go page 2
3) zoom in with pinch
4) vertical pan work as expected.

it is a really strange problem that not allow me to use a function "go to page" normally. I'm fighting with it at least since 1 full day .

Can anyone help me? i seen and tried with all apple example of scrollview, but none of it use multiple images + zoom.

Thanks!.

solved, after about 16 hours of (useless) debug.

[myScrollViewExt removeFromSuperview];
[myScrollViewInt removeFromSuperview];

[myScrollViewInt scrollRectToVisible:frame animated:YES];
	
[self.view addSubview:myScrollViewExt];
[myScrollViewExt addSubview:myScrollViewInt];

So, it is only 1 of the thousands tries that i done.

I hope that it can help someone in future.
