Version 6.10.6 Changelog (June 28th, 2019)

New

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.

Realtime collaboration support has been added to Tools.framework. The Collaboration sample in the SDK has also been updated to include a WebViewer Server backend in addition to the existing Firebase backend. For more information please see our collaboration guide.
Measurement annotations, created with the PTRulerCreate, PTAreaCreate, or PTPerimeterCreate tools, can now be calibrated to a specific reference value from the measurement annotation's "Calibrate" menu item.
All controls created internally by the PTDocumentViewController class are now overridable via the PTOverrides system.
Properties have been added to the PTPDFViewCtrl class for existing getter and/or setter methods.

Fixed a bug preventing long-pressing to move the cursor while editing a text form-field.
A number of miscellaneous bug fixes.

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.
