Declaration
class PDFAnnotationTextOverview
Each PDFAnnotationText object has a PDFAnnotationPopup object associated with it. In its closed state, the annotation appears as an icon. In its open state, it displays as a pop-up window containing the text of the note. Note that your application must do the work to put up a window containing the text in response to a PDFViewAnnotationHitNotification. Currently, text annotations do not scale and rotate with the page.
