Derived: UIKit.UIActivityItemProvider

UIKit.UIActivityItemSource

Attributes: ProtocolAttribute ProtocolMemberAttribute

Implements: INativeObject IDisposable

Remarks

This class should not be used for complex processing, as it is called on the main UI thread. Applications that require complex processing of data before passing it to UIActivity objects should implement UIActivityItemProvider.

Properties

Name	Description
Handle	Handle (pointer) to the unmanaged object representation. (Inherited from INativeObject)

Methods

Name	Description
GetDataTypeIdentifierForActivity(UIActivityViewController, NSString)	If the specified provides NSData, this method returns the Uniform Type Identifier (UTI) of the item.
GetItemForActivity(UIActivityViewController, NSString)	The data to be acted upon by the specified actitivtyType.
GetLinkMetadata(UIActivityViewController)
GetPlaceholderData(UIActivityViewController)	Returns data that can be used as a placeholder for real data.
GetShareRecipients(UIActivityViewController)
GetSubjectForActivity(UIActivityViewController, NSString)	Returns the subject for the specified .
GetThumbnailImageForActivity(UIActivityViewController, NSString, CGSize)	Returns the preview image for the specified .

Extension Methods
