How do I implement UIScrollView programatically - xcode

Question

I am launching detail pages from a UITableView and within that detail page there is an image. I would like it to be zoomable, so I'd like the contents of that detail page to sit inside a scrollView. So far no luck, the labels, textviews and images are fine, but I can't get the ScrollView implemented.
here is my .m: THANKS!
- (void)viewDidLoad {
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
scrollView.contentSize = CGSizeMake(320, 700);
scrollView.clipsToBounds = YES;
super.view.backgroundColor = [UIColor whiteColor];
[scrollView setUserInteractionEnabled:YES];
self.navigationItem.title = [NSString stringWithFormat:selectedCellItem];
CGRect frame = CGRectMake(0, 0, 10, 10);
self.view = [[UIView alloc] initWithFrame:frame];
self.view.backgroundColor = [UIColor whiteColor];
frame = CGRectMake(0, 320, 10, 10);
UILabel *label = [[UILabel alloc] initWithFrame:frame];
//label.text = selectedCellItem;
label.font=[UIFont fontWithName:#"Verdana-Bold" size:20.0];
label.textAlignment = UITextAlignmentCenter;
[self.view addSubview:label];
[label release];
frame = CGRectMake(0, 320, 320, 60); //Description
UITextView *labelDesc = [[UITextView alloc] initWithFrame:frame];
labelDesc.text = selectedCellDesc;
labelDesc.font=[UIFont fontWithName:#"Verdana" size:12.0];
labelDesc.textAlignment = UITextAlignmentLeft;
//labelDesc.textAlignment = UITextAlignmentTop;
[self.view addSubview:labelDesc];
[labelDesc release];
frame = CGRectMake(0, 0, 320, 320); //Image
UIImageView *imageItem = [[UIImageView alloc] initWithFrame:frame];
[imageItem setImage:[UIImage imageNamed:selectedCellImage]];
// GET THIS ONE WORKING RIGHT>>[imageItem setImage:[UIImage imageNamed:[NSString stringWithFormat:#"%#.png", [[NSBundle mainBundle] bundlePath], selectedCellImage]]]; //use
//imageItem = [[UIImageView alloc] initWithContentsOfFile:[NSString stringWithFormat:#"shirt.png", [[NSBundle mainBundle] bundlePath]]];
//labelDesc.font=[UIFont fontWithName:#"Zapfino" size:13.0];
//labelDesc.textAlignment = UITextAlignmentCenter;
imageItem.contentMode = UIViewContentModeScaleAspectFit;
[self.view addSubview:imageItem];
//[imageItem release];
[super viewDidLoad];
}
/*
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
*/
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
#end

I think that you're missing the following line to add the UIScrollView as a subview.
[self.view addSubView:scrollView];
