Because it's accessed using a literal string, not a constant string.

Pull request overview

Adds a manual managed binding for PdfViewAnnotationHitEventArgs.AnnotationHit in PdfKit, because Apple’s userInfo key is a literal string ("PDFAnnotationHit") rather than an exported constant.

Changes:

  • Added a new partial implementation of PdfViewAnnotationHitEventArgs.AnnotationHit that reads "PDFAnnotationHit" from NSNotification.UserInfo.
  • Removed the incorrect generated [Export ("PDFAnnotationHit")] property from the binding definition so it won’t be emitted as a (non-existent) native constant lookup.
  • Added monotouch tests to validate AnnotationHit extraction (including a missing-UserInfo case).

File Description
tests/monotouch-test/PdfKit/PdfAnnotationTest.cs Adds tests that build an NSNotification with userInfo["PDFAnnotationHit"] and validate AnnotationHit behavior.
src/PdfKit/PdfViewAnnotationHitEventArgs.cs New manual partial binding that reads the literal userInfo key and returns a PdfAnnotation.
src/pdfkit.cs Removes the autogenerated binding member for AnnotationHit and notes it’s manually bound.
src/frameworks.sources Ensures the new manual binding source file is compiled into the PdfKit sources.

PdfViewAnnotationHitEventArgs is generated as a public partial class (see bgen's event-args generation). This partial declaration has no access modifier, so it defaults to internal and will cause a partial-type accessibility mismatch at compile time. Make this declaration public partial class ... to match the generated part.

Suggested change
partial class PdfViewAnnotationHitEventArgs : NSNotificationEventArgs {
public partial class PdfViewAnnotationHitEventArgs : NSNotificationEventArgs {

// This property needs a manual binding, because it's not using a constant string value,
// it's using a literal string value (as per Apple's documentation).

This new PdfKit source file doesn't enable nullable context (unlike the other PdfKit sources) and also uses a file-scoped namespace while the rest of src/PdfKit/*.cs uses block-scoped namespace PdfKit { ... }. Consider adding #nullable enable and matching the existing namespace style for consistency within the PdfKit sources.

PdfViewAnnotationHitEventArgs is marked [NoiOS][NoTV][NoMacCatalyst] in src/pdfkit.cs, but this manual partial type is currently compiled unconditionally. If that platform restriction is intentional, wrap this file (or at least this type) in the corresponding #if MONOMAC/platform guard so the type/property doesn't appear on unsupported platforms.
