terminating app due uncaught exception 'nsinternalinconsistencyexception', reason: 'error: required method not implemented: -[jsqmessagesviewcontroller collectionview:avatarimagedataforitematindexpath:]
can me please? thanks
it required need override , pass nil.
override func collectionview(collectionview: jsqmessagescollectionview!, avatarimagedataforitematindexpath indexpath: nsindexpath!) -> jsqmessageavatarimagedatasource? { return nil } you can add same file. should good.
