UIButtons on tableFooterView not responding to events - iphone

Question

I've successfully added some UIButtons to a custom tableFooterView. The problem is that the button events does not get called. Also, the image relative to the UIControlStateHighlighted doesn't come up. Any ideas?
I've tried all I could think of, but I can't find the trick. I'm reporting here the interesting part of the UITableViewController:
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection: (NSInteger)section
{
CGRect footerFrame = CGRectMake(0.0, 0.0, 480, 190);
_footerView = [[UIImageView alloc] initWithFrame: footerFrame];
_footerView.image = [UIImage imageNamed:#"tableviewfooter.png"];
_footerView.contentMode = UIViewContentModeTopLeft;
UIButton *addExam = [self createButtonWithFrame: CGRectMake(10, 30, 460, 58) Target: self Selector: #selector(addNewItem:) Image: #"additem.png" ImagePressed: #"additem_pressed.png"];
[_footerView addSubview:addExam];
return _footerView;
}
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection: (NSInteger) section
{
return 190;
}
- (void) addNewItem:(id)sender
{
// This get's never called
NSLog(#"Pressed");
}
- (UIButton*) createButtonWithFrame: (CGRect) frame Target:(id)target Selector:(SEL)selector Image:(NSString *)image ImagePressed:(NSString *)imagePressed
{
UIButton *button = [[UIButton alloc] initWithFrame:frame];
UIImage *newImage = [UIImage imageNamed: image];
[button setBackgroundImage:newImage forState:UIControlStateNormal];
UIImage *newPressedImage = [UIImage imageNamed: imagePressed];
[button setBackgroundImage:newPressedImage forState:UIControlStateHighlighted];
[button addTarget:target action:selector forControlEvents:UIControlEventTouchUpInside];
return button;
}
Thanks for your help!

I do not think UIImageView was designed to work well as a container for other views, especially UIButtons. For one, UIImageViews, when created, have their userInteractionsEnabled property set to false by default.
I would just create a simple UIView as your footer view and then add both the UIButton and the UIImageView directly to it.
