// it will find a partial pack and resume it. Notice how the network and disk activity shows
// that a download is indeed ocurring, while there are no notifications posted on progress.

Since an MGLAnnotationView is a UIView you can use familiar APIs to manipulate it. For example, on devices that support 3D touch, you can transform the view as a function of the touch force.

override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
    super.touchesMoved(touches, withEvent: event)

    if let touch = touches.first {
        let normalizedForce = touch.force / touch.maximumPossibleForce * 2.5
        self.transform = CGAffineTransformMakeScale(1 + normalizedForce, 1 + normalizedForce)
    }

### Keybase proof

I hereby claim:

  * I am boundsj on github.
  * I am boundsj (https://keybase.io/boundsj) on keybase.
  * I have a public key whose fingerprint is 8C6A AF5D 5922 5BF4 45A2  1278 54F0 7E43 1D15 92FF

To claim this, I am signing this object:

// in a tap gesture recognizer handler in view controller
// assuming you have a text view in controller called "myTextView"

- (void)myTextViewTapped:(UITapGestureRecognizer *)recognizer {
    // get tap location in view in question
    CGPoint location = [recognizer locationInView:self.myTextView];
    
    // adjust location for text view's offsets
    location.x -= self.myTextView.textContainerInset.left;
    location.y -= self.myTextView.textContainerInset.top;
