How do I add custom images #17
Description
I was adding image attachments with NSTextAttachment in my custom textView.(Like below)
let textAttachment = NSTextAttachment() textAttachment.bounds = CGRect(x: 0, y: (textView.font!.capHeight - image.size.height).rounded() / 2, width: image.size.width, height: image.size.height) textAttachment.image = image let attrStringWithImage = NSAttributedString(attachment: textAttachment) textView.textStorage.replaceCharacters(in: currentRange, with: attrStringWithImage)
Is there a way to add images(don't care if is it an NSTextAttachment or a suffixedAttachment) on the textView with TwitterTextEditor?
I found I can get hashtags with regex and place an UIImage or UIView after that hashtag. But I can't find a way how to add just UIImage itself like an NSTextAttachment.

Hi, @Topwiz.
This is actually bit difficult on current Twitter Text Editor API design, since it is based on plain text not attributed text.
To use
NSTextAttachmentto render image within the text view (which is possible in Twitter Text Editor,) but it need to add that attribute to theU+FFFC(NSTextAttachment.character) in the plain text, however Twitter Text Editor API is, intentionally separate plain text updating and attribute updating logic, therefore it is bit difficult to useNSTextAttachment.I understand however such use case may exist, so will explore new API for that.

I use the TwitterTextEditor
layoutManageras the layout backend. And set the image placeholder with space and keep the range. Then replace that space withSuffixedAttachment. It works. Maybe that is what you need.https://github.com/TwidereProject/ActiveLabel.swift/blob/master/Sources/ActiveLabel/ActiveLabel.swift#L312-L342
