未检测到UITouches

Question

我的UItouches未在我的幻灯片nib文件中检测到。问题是什么？谁能帮忙？

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

幻灯片实施

@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

幻灯片是一个UIViewController和touchesBegan只叫上UIView。您需要继承UIView以捕捉触摸。
