        return YES;
    } else if(interfaceOrientation==UIInterfaceOrientationLandscapeLeft ||interfaceOrientation==UIInterfaceOrientationLandscapeRight)

    UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];

    if(orientation==UIInterfaceOrientationPortrait || orientation==UIInterfaceOrientationPortraitUpsideDown)
    {CGRect frame=CGRectMake(0,45,320,480);
        [sample_scroll_view setFrame:frame];
        sample_scroll_view.contentSize = CGSizeMake(2560,275);
        sample_scroll_view.pagingEnabled=YES;
        sample_scroll_view.autoresizingMask =
        ( UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
        sample_scroll_view.autoresizesSubviews = YES;
}
else if (orientation==UIInterfaceOrientationLandscapeLeft || orientation==UIInterfaceOrientationLandscapeRight)
{
CGRect frame=CGRectMake(0,45,480,275);
        [scroll_view2 setFrame:frame];
        scroll_view2.contentSize = CGSizeMake(3140,275);
        scroll_view2.maximumZoomScale = 4.0;
        scroll_view2.minimumZoomScale = 0.75;
        scroll_view2.bounces = NO;
        scroll_view2.pagingEnabled=YES;

您可以在xib文件的“视图”标签下的自动调整大小模式下进行一些设置。
