# Expo Paste Input Patch
2
+
3
+
`expo-paste-input` observes `UITextView.textDidChangeNotification` and treats any
4
+
`NSTextAttachment` in the text view's `attributedText` as a pasted image. When
5
+
it can't find a real image payload on an attachment, it falls back to
6
+
`image(forBounds:)` and, failing that, to a `drawHierarchy` screenshot of the
7
+
text view at the attachment's glyph rect.
8
+
9
+
iOS Dictation inserts its own `NSTextAttachment` (the shimmer/cursor indicator)
10
+
into the text view during dictation. Those attachments don't carry real image
11
+
data, so the fallbacks would fire — emitting a zoomed-in screenshot of the
12
+
composer as if the user had pasted an image at the end of dictation.
13
+
14
+
This patch:
15
+
16
+
- Removes the `image(forBounds:)` and `renderTextAttachment` fallbacks in
17
+
`extractMediaPayload` so the library only accepts attachments carrying a real
18
+
payload (`fileWrapper`, `contents`, or `image`).
19
+
- Only sanitizes (deletes) attachment ranges that produced a payload, and
20
+
skips the "unsupported" toast when an attachment has no payload. Unknown
21
+
system attachments like the dictation placeholder are left alone rather
22
+
than being ripped out from under iOS.
