How to add a gesture recognizer to a form drawn by uibezierpath

Question

I draw a circle in the drawRect function in a subclass of UIView

- (void)drawRect:(CGRect)rect
{
    CGContextRef contextRef = UIGraphicsGetCurrentContext();  
    CGContextSetLineWidth(contextRef, 2.0);
    CGContextSetRGBFillColor(contextRef, 0, 0, 1.0, 1.0);
    CGContextSetRGBStrokeColor(contextRef, 0, 0, 1.0, 1.0);
    CGRect circlePoint = (CGRectMake(self.bounds.size.width/3, self.bounds.size.height/2, 200.0, 200.0));

    CGContextFillEllipseInRect(contextRef, circlePoint);
}

I want to add a gesture recognizer to the circle to make it tappable

UITapGestureRecognizer *singleFingerTap =
[[UITapGestureRecognizer alloc] initWithTarget:self
                                        action:@selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleFingerTap];

I thought of dragging the UIGestureRecognizer onto the view (in the storyboard) where the big circle will be, but the circle is much larger than the UIGestureRecognizer widget.

How can I either combine the code or assign a UIGestureRecognizer to the view area, exactly the same as the size and location of the circle?

         self.shape = [UIBezierPath bezierPathWithOvalInRect:(CGRectMake(self.bounds.size.width/3, self.bounds.size.height/3, 200.0, 200.0))];

-(void)handleSingleTap:(UITapGestureRecognizer *) tapper {
    if ([self.mainView.shape containsPoint:[tapper locationInView:self.mainView]]) {
        NSLog(@"tapped");
    }
