Scrollview inside containerView won't scroll? - iphone

Question

I have a UITableViewController subclass that has a container UIView which has 1 of 2 subviews: the tableview, or a UIScroll depending on whether or not the view is "flipped".
my viewDidLoad() method adds the tableview to the container:
[kContainerView addSubview: self.tableView];
self.view = kContainerView;
and initializes the UIScrollview with an 900x600 image and sets itself as the delegate:
kSBCanvasScrollView = [[UIScrollView alloc] initWithFrame:bounds];
[kSBCanvasScrollView setDelegate: self];
kSBImage = [[UIImageView alloc] initWithImage:img];
[kSBCanvasScrollView addSubview:kSBImage];
[kSBCanvasScrollView setContentSize:[img size]];
[kSBCanvasScrollView setMinimumZoomScale:0.5];
The the front "Table side" of the view works fine. I then flip the view when the user selects a button on the toolbar by doing the following:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0f];
[UIView setAnimationDelegate:self];
if (kSBCanvasIsVisible==NO) {
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:kContainerView cache:YES];
[self.tableView removeFromSuperview];
[kContainerView addSubview:kSBCanvasScrollView];
kSBCanvasIsVisible = YES;
} else {
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:kContainerView cache:YES];
[kSBCanvasScrollView removeFromSuperview];
[kContainerView addSubview:self.tableView];
kSBCanvasIsVisible = NO;
}
[UIView commitAnimations];
It flips just like I want, but the kSBCanvasScrollView does not scroll. The pinch gesture works. Why won't the view scroll? Perhaps it relates to the fact this is a TableViewController?

Is your scrollview 320 x 460? I had to make the scroll view the same , or smaller than the iphone screen for it to work(In IB but not necessarily in the
[kSBCanvasScrollView setContentSize:[img size];).
Did you write:
[kSBCanvasScrollView setScrollEnabled:YES];
PS: I did try this. It worked for me...
