能具体点吗？可以发出来代码看看

如上图所示  uiscrollview是嵌套在uitableviewcell里面的

-(void)refreshCell:(NSArray*)a
{
    NSMutableArray * array = [NSMutableArray new];
    for( NSInteger i = 0; i < 3; ++ i )
    for(HonorModel * m in a )
    {
        [array addObject:m];
    }
    
    [self layoutIfNeeded];
    
    //
    self.honorArray = [array copy];
    
    if( !self.cView.superview )
       [self.scrollView addSubview:self.cView];
    
    //
    for( NSInteger i = 0; i < array.count; ++ i )
    {
        HonorModel * m = array[i];
        
        UIImageView * imgView = [[UIImageView alloc]initWithFrame:CGRectMake(HEAD_IMG_DIS + i*(HEAD_IMG_DIS+HEAD_IMG_W), (self.scrollView.frame.size.height - HEAD_IMG_H)/2.0, HEAD_IMG_W, HEAD_IMG_H)];
        [imgView sd_setImageWithURL:[NSURL URLWithString:m.headphoto] placeholderImage:DEFAULT_ICON];
        imgView.layer.cornerRadius = HEAD_IMG_H/2.0;
        imgView.layer.masksToBounds = YES;
        
        [self.cView addSubview:imgView];
        self.cView.userInteractionEnabled = YES;
        self.cView.frame = CGRectMake(0, 0, imgView.frame.size.width + imgView.frame.origin.x, self.sViewH);
        
        self.scrollView.contentSize = self.cView.frame.size;
        
        //
        imgView.tag = i;
        imgView.userInteractionEnabled = YES;
        UITapGestureRecognizer * g = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(headClicked:)];
        [imgView addGestureRecognizer:g];
        
        DLog(@"imgView:%@",imgView);
    }
}

上面的是代码，UIScrollview可以滚动，但是headClicked 并没有被调用....
