UIScrollView crashes app when touched

I am running into a very annoying problem: I am creating an UIScrollView that containes an UIView that contains some buttons. The UIView with buttons work fine. But the UIScrollView, no matter what I do with it, when touched, crashes. It doesn't make any difference it's empty or not. It keep开发者_开发问答s crashing.

I am very lost and don't know what else to try. Thanks very much.

In the viewController.h

@interface tagstestViewController : UIViewController <UIScrollViewDelegate> {
        UIScrollView            *scrollViewContainer;
}

@property (nonatomic, retain) UIScrollView *scrollViewContainer;

In the viewController.m:

    UIScrollView *scv       =   [[UIScrollView alloc] initWithFrame:CGRectMake(0,0, 320, 200)];
    scv.backgroundColor     =   [UIColor blackColor];
    scv.autoresizingMask    =   UIViewAutoresizingFlexibleHeight;   
    scv.bounces             =   YES;
    scv.scrollEnabled       =   YES;
    scv.clipsToBounds       =   YES;
    scv.delegate            =   self;

    [self setScrollViewContainer:scv];

    [scv release];

    [self.view addSubview:scrollViewContainer];

Are you releasing your viewController right after you add its view into the view hierarachy? Because if you do that, I noticed that even though the application keeps running fine, if you use "scv.delegate = self", it will crash when it tries to deliver the delegated messages to the viewController.
