PDF documents in App Kit are always rendered inside a document view controller instance.
Depending on your integration your application should use one of the following document view controllers:
MuPDFDKDocumentViewController( for the Default UI )
MuPDFDKBasicDocumentViewController( for a Custom UI )
The Default UI involves the least effort and should handle all your requirements unless you need nontrivial customization, more than altering colors and icons within the UI. Simply create and present a
MuPDFDKDocumentViewController instance. With the Default UI, all user editing features are handled internally to the
MuPDFDKDocumentViewController instance, without you as application programmer having to interact with the process.
For the Custom UI, a
MuPDFDKBasicDocumentViewController instance provides a view on the document, but with minimal UI. It is the application developer's responsibility to create additional views and menus with UI elements via which the user can perform operations on the document. An application developer would typically create a UIViewController subclass that acts as a container for a
MuPDFDKBasicDocumentViewController instance, along with additional views for UI. The
UIViewController subclass would respond to the regular view-related
UIViewController events in the usual way, and additionally implement two further protocols to make the UI responsive to events relating to the document and its view:
ARDKBasicDocViewDelegate- this allows the document view to inform us of events and request information, regarding scrolling, user taps, etc.
ARDKDocumentEventTarget- this allows the document itself to inform us of events, regarding the loading of the document and selection changes etc.
View Controller interfaces
In order to control pasteboard copy and paste information, your document view controller instance should create its own implementation of a pasteboard class following the
ARDKPastebord protocol is as follows:
@protocol ARDKPasteboard /// Whether the pasteboard has textual content @property(nonatomic, readonly) BOOL ARDKPasteboard_hasStrings; /// Set/get the current contents of the clipboard @property(nullable,nonatomic,copy,setter=ARDKPasteboard_setString:) NSString *ARDKPasteboard_string; /// The number of times the pasteboard’s contents have changed. @property(readonly, nonatomic) NSInteger ARDKPasteboard_changeCount; @end
For secure applications an application may require to disable pasteboard information completely.
Once created any pasteboard class should be assigned to the
pasteboard object on the document view controller.
Assuming an application developer has created their own pasteboard class as
MyPasteboard this would be assigned as follows:
docVC.pasteboard = MyPasteboard()
docVC.pasteboard = [[MyPasteboard alloc] init];
