  • A new OCG (Optional Content Groups) layer control that lists the OCG layers in a document and allows specific layers to be shown or hidden. The OCG layer control is displayed in the PTNavigationListsViewController. By default the layer control is shown or hidden when OCG layers are detected in the document. This automatic behavior can be changed with the pdfLayerViewControllerVisibility property on the PTNavigationListsViewController class.

API diff

  • Getter and setter methods on the PTPDFViewCtrl class that are now wrapped in properties are no longer available in Swift. For example, previously to get the page count of a PDFViewCtrl, pdfViewCtrl.getPageCount() would be used. The GetPageCount method can still be used from Objective-C, but the pageCount property must be used from Swift: pdfViewCtrl.pageCount.

  • The UICollectionView used by the PTThumbnailsViewController class can now be accessed via a collectionView property.

  • An API diff from the previous version is available.
