Question

I have a UIScrollView , and enabled scrolling . Its working fine with delegate methods.

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView
{
    return MyScrollView;
}

But the problem i am facing is, i need to Zoom out the UIScrollView when I rotate the iPad.
What I have to code in this function

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
    {
if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
       interfaceOrientation == UIInterfaceOrientationLandscapeRight){

    }
    if(interfaceOrientation == UIInterfaceOrientationPortrait ||
       interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
    {

    }
}

Answer 1

You can use this method: - (void)setZoomScale:(float)scale animated:(BOOL)animated and set the scale to minimum zoom scale of your scrollview that you might have configured when you have created the scrollview.

Example:

[MyScrollview setZoomScale:minimuzoomscale animated:YES];

Place above line in shouldAutorotate.
