You can create a custom button object (New File > SubClass of: UIButton) and add to the bottom

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    if (CGRectContainsPoint(self.bounds, point)) {
        NSLog("Button got hit");
        return self;
    }
    else {
        return nil
    }
}

and use this custom button to in your viewController

myCustomButton * m_pFacebookPostButton = [[myCustomButton alloc] init];

Seems like the issue regarding Quartz2D.

Refer this==> Is it possible to successful animate a moving UIButton?

Engin Kurutepe stated that,

This sounds a bit too complicated for UIKit and CoreAnimation. It seems like you're developing something like a game. Why not use a global animation timer for let's say ~60 fps and do your drawing in Quartz2D? Then for each touch you could quickly check any hits between Quartz refreshes.

EDIT: Try using other animation methods.

Example:

-(void)hello
{
    NSLog(@"hello");

}
-(void)animationDone
{
    NSLog(@"done");
}

UIButton *button=[[UIButton alloc]init];
button.frame = CGRectMake(30, 50, 100, 100);
button.backgroundColor=[UIColor redColor];
[button addTarget:self action:@selector(hello) forControlEvents:UIControlEventTouchUpInside];
  [self.view addSubview:button];
// animate
[UIView beginAnimations:@"button_in" context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationDone)];
[UIView setAnimationDuration:1.0];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
[UIView setAnimationBeginsFromCurrentState:YES];
[button setFrame:CGRectMake(100.0, 100.0, 100.0, 30.0)];
[UIView commitAnimations];

Hope it helps...
