[MacMeDan]

Correct me if I am wrong but your issue is when an incoming message is received the current message you are typing in the InputBar gets lost?

if that is the case I would check to see if you reload the entire view when you get a message.

If you would provide that code we can help more.

I would take a look at this method it just screams trouble reloadMessagesView() especially within retrieveMessage I could see that causing the issue you have described.

let me know if that helps 🖖🏽

[dimsancing2015]

I delete reloadMessagesView() but still happen error!

Thanks

[MacMeDan]

Did that solve the issue for you?

[dimsancing2015]

Didn't solve.

[vic2tee4u]

Hello, have you been able to solve this issue?. I am facing the exact same problem.

[vic2tee4u]

Quick question , are you running on Version 7.3.3 or version 7.3.4?

[dimsancing2015]

My Xcode is Version 8.2.1 (8C1002).

[Tsarfolk]

change finishSendingMessage() to finishReceivingMessage()

Hello everyone!

I'm sorry to inform the community that I'm officially deprecating this project. 😢 Please read my blog post for details:

http://www.jessesquires.com/blog/officially-deprecating-jsqmessagesviewcontroller/

Thus, I'm closing all issues and pull requests and making the necessary updates to formally deprecate the library. I'm sorry if this is unexpected or disappointing. Please know that this was an extremely difficult decision to make. I'd like to thank everyone here for contributing and making this project so great. It was a fun 4 years. 😊

Thanks for understanding, — jsq
