An iOS UIView subclass that displays a rounded rect "bubble", containing a text message, pointing at a specified button or view.
A CMPopTipView will automatically position itself within the view so that it is pointing at the specified button or view, positioning the "pointer" as necessary.
A CMPopTipView can be pointed at any UIView within the containing view. It can also be pointed at a UIBarButtonItem within either a UINavigationBar or a UIToolbar and it will automatically position itself to point at the target.
- The background and text colors can be customised if the defaults are not suitable.
- Two animation options are available for when a CMPopTipView is presented: "slide" and "pop".
- A CMPopTipView can be dismissed by the user tapping on it. It can also be dismissed programatically.
- CMPopTipView is rendered entirely by Core Graphics
