Here is what you can do to get what you wanted ….. In this example i have created 7 views

UITapGestureRecognizer* gestureRecognizer;
UIView* myView;
for (int i = 0; i < 8; i++) 
{
    gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doSomthing:)];
    gestureRecognizer.numberOfTapsRequired = 1;//or what ever you want

    myView = [[UIView alloc] initWithFrame:CGRectMake(10, i*30, 30, 28)];
    myView.backgroundColor = [UIColor redColor];
    myView.tag = 100+i;
    [self.view addSubview:myView];
    [myView addGestureRecognizer:gestureRecognizer];
    [myView release];
    [gestureRecognizer release];
}

Now you need to implement the method like this

-(void)doSomthing:(id)sender
{
    UIView* temp = [(UITapGestureRecognizer*)sender view];
    // here you get the view you wanted
    NSLog(@"view number :%d",temp.tag);
}

I think this should help you
