Released object crashes App -- problem with alloc/init memory management

Question

I have a flipView class that I allocate and initiate. But, when I release it the app crashes. If I don't release it, the app works fine, so it seems. The error message I receive when I release it is:

Malloc - error for object: object pointer being freed was not allocated.

If you could please assist me, I would be grateful.

- (IBAction)showInfo {
    FlippedProduceView *flippedView = [[FlippedProduceView alloc]initWithIndexPath:index];

    flippedView.flipDelegate = self;

    flippedView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

    [self presentModalViewController:flippedView animated:YES];

    //[flippedView release]; //******** Maybe A Memory Leak *********\\
}

Answer 1

Your presentModalViewController: message should call retain on the flippedView. That will keep it from being deallocated until presentModalViewController:'s purpose for it is complete. You can then call [flippedView release] as you should at the end of this routine. Unless there is something else missing?
