iOS Scroll view stopped working

[StevenHu]

I'm puzzled why my scroll height quit working. It's set at 2285 height, but scrolls only about 30-40 pixels. Earlier, it was closer to 2000 and it worked fine in the simulator and device, then I lengthened it a little. The number is the same below as in IB's Scroll View Size dialog.

No error or warning messages. I trashed the earlier builds and did a clean. The scroll view is connected to the File's Owner correctly (to myScrollView). Here's the implementation file. Any idea why the scroll would shorten dramatically?

Thanks!

@implementation FrontSuspension1

@synthesize myScrollView;


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
	myScrollView.contentSize=CGSizeMake(320,2285); 
[super viewDidLoad];
 
self.title = NSLocalizedString(@"Front Suspension", @""); // See Localizable.strings/en
}

- (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 {
	// Release any retained subviews of the main view.
	// e.g. self.myOutlet = nil;
}


- (void)dealloc {
	[myScrollView release];
    [super dealloc];
}
