How to detect touches on UIImageView while it's animating

I have an UIImageview which moves from a position to another. When I try to tap on the image during the animation touch event delegate method is not called. But when I tap on image after the completion of the animation, the delegate method executes. How can I detect the touch event on the uiimageview while it is changing its position.

my code:

vwb2 = [[UIView alloc] initWithFrame:CGRectMake(240, 500, 50, 50)];
[self.view addSubview:vwb2];
ballon2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"b2.png"]];
ballon2.userInteractionEnabled = TRUE;
ballon2.frame = CGRectMake(0, 0, 50, 50);
[vwb2 addSubview:ballon2];
[ballon2 release];

Edit:

My code for animation:

[UIView animateWithDuration:2.0
                 animations:^{ 
                     vwb1.center = CGPointMake(260, 40);
                 } 
                 completion:^(BOOL finished){

                     [UIView animateWithDuration:1.5
                                      animations:^{ 
                                          vwb2.center = CGPointMake(260, 100);
                                      } 
                                      completion:^(BOOL finished){
                                          [UIView animateWithDuration:1.0
                                                           animations:^{ 
                                                               vwb3.center = CGPointMake(260, 160);
                                                           } 
                                                           completion:^(BOOL finished){
                                                               [UIView animateWithDuration:1.0
                                                                                animations:^{

                                                                                } 
                                                                                completion:^(BOOL finished){

You can get position...

-(CGRect) getPos
{
    CGRect pos = 0;
    CALayer *layer = yourAnimationView.layer.presentationLayer;
    if(layer)
        pos = layer.frame;

    return pos;
}

And check CGRectContainsPoint([self getPos],touchPoint) in touchesEnded method
(My old answer)

In my project, I did not detect any touch event of UIImageView. I detected touch event of parent view and used touch point and UIImageView's rect to detect the UIImageView was touched. Maybe you can try it.

- (void) touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event
{
    UITouch *touch = [touches anyObject];
    CGPoint pt = [touch locationInView:self];
    bool inX = NO;
    bool inY = NO;
    if(pt.x >= myImgView.frame.origin.x && pt.x <= myImgView.frame.origin.x + myImgView.frame.size.width)
        inX = YES;
    if(pt.y >= myImgView.frame.origin.y && pt.y <= myImgView.frame.origin.y + myImgView.frame.size.height)
        inY = YES;
    if(inX && inY)
        NSLog(@"myImgView is touched");
}

I have posted correct solution as edit to my original question
