addAttachmentData(_:typeIdentifier:filename:)

Attaches arbitrary content to the message.

Declaration

func addAttachmentData(_ attachmentData: Data, typeIdentifier uti: String, filename: String) -> Bool

Parameters

attachmentData

Content in the form of an NSData object to attach to the message. Must not be nil.

A valid Uniform Type Identifier (UTI) appropriate for the attachment data. See Uniform Type Identifiers Reference. Must not be nil.

filename

The name to present to the user, in the message UI, for the data attachment.

This method is especially useful when the attachment you want to add to a message does not have a file system representation. This can be the case, for example, for programmatically composed audiovisual content.
