UITouches not detecting

Question

My UItouches is not detecting in my Slideshow nib file. What is the problem? Can anyone help?

@class Slideshow;
@interface RootViewController : UIViewController{
PreferencesController *preferencesController;
Slideshow *slideshow;}

Slideshow Implementation

@implementation Slideshow
- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
NSLog(@"touches begin");
}
- (void)viewDidLoad
{

UIImageView *frontView = [[UIImageView alloc] initWithFrame:self.view.bounds];
frontView.backgroundColor = [UIColor blackColor];
frontView.image = [UIImage imageNamed:@"apple.png"];
frontView.userInteractionEnabled = YES;

[self.view addSubview:frontView];

[frontView release];
}@end

Answer 1

Slideshow is a UIViewController and touchesBegan is only called on a UIView . You need to subclass UIView to capture touches.
