What NSData can display a UITextView from an NSTextAttachment?

Question

I have successfully used NSTextAttachmentin UITextViewfor some time, but only ever used a property image, for example:

NSTextAttachment *attachment = [[NSTextAttachment alloc] initWithData:nil ofType:nil];
attachment.image = [UIImage imageNamed:@"someImage"];

I am interested in trying to use initWithData:ofType:, however, I cannot find documentation describing which type the NSDataclass NSTextAttachmentthat can be mapped to supports UITextView.

For example, can I transfer data NSStringor some UIView? Or even a PDF? Or is it limited by actual data UIImage?
