LinkPreviewView was previously used to show link previews in chat and in Share Extension when text being shared contained an url. This commit renames LinkPreviewView to CVLinkPreviewView and simplifies the component to only handle sent links - support for showing intermediate "loading" state as well as having a cancel button to remove link preview - has been removed from this class.
OutgoingLinkPreviewView is used to show "link preview draft" in the chat input toolbar. This commit renames the class to LinkPreviewView and adopts this component to be used in Share Extension in place of the component mentioned above.
All those changes result in update link preview UI in Share Extension - visible when sharing a website from Safari or other mobile browser.
• now inset from bubble's edges
• updated background color
• updated description text color and size
Also includes quite a bunch of cleanup in LinkPreviewView.
OWSMath.swift overlaps somewhat with Math+OWS.swift but no worse than
OWSMath.h did previously. There are future refactoring efforts that
should occur there to use more of the extensions of Math+OWS.swift and
less of the extensions from OWSMath.swift
This included:
- Removing unavailable inits wholesale if no longer `required`
- Marking a few classes `final` so they could continue using
`Self(...)` rather than `OWSWhatever(...)`
Also:
- Remove AtomicUInt's @objc, it's no longer used from ObjC
- Remove Codable conformances, they would implicitly use shared locks
and weren't used in practice
