AdvancedOptionsViewController in Demo App project isn't functional

[glennposadas]

The controller just doesn't work. I'm trying to learn how to use stream chat by using my own keys and tokens so I thought this advanced option is a good thing but isn't completed yet.

Also, I have a side question. The Stream can be possibly integrated into an Objective-C project, yes?

Thanks!

Hi @glennposadas!

Thank you for opening the issue!
We will investigate this as soon as we can and will get back to you 👍

Yes in theory it should. But we don't have many customers with Obj-C projects, so maybe you can find minor problems. But if you do, please open an issue here and we will get that fixed for sure 🙂

Best,
Nuno

Thanks, Nuno!

Hey, @glennposadas

Did you find any issues with the Objective-C integration? I am going to transfer this issue to a Discussion to see if there is more appetite to enable the advanced settings. Of course, in the meantime, you can easily swap out the API Keys / Tokens to switch the Demo app to your own Stream application.

Thanks,
Adam

Hey @adamrushy and @nuno-vieira I just experienced a seemingly tough Objc integration problem, so I came here and found my own thread.

Basically, our project is Objective-C based, of course there have been a lof of Swift codes and even libraries already, but this one seems impossible to solve.

I have been able to use the chat by having Swift extensions of my Objective-C controllers.

But this problem comes...

I need to remove the subtitle of the navBar (ChatChannelHeaderView) of the chat screen.

    let channelVC = ChatChannelVC()
    channelVC.headerView.titleContainerView.content = ("title here", nil)
    channelVC.updateContent()

This does not work. I know you clearly mentioned in this documentation link: https://getstream.io/chat/docs/sdk/ios/uikit/views/channel-header-view/

that the way to customized the title container is to subclass it, like so:

import StreamChatUI
import UIKit

class FNChatTitleView: ChatThreadHeaderView {
  override func updateContent() {
    super.updateContent()

    titleContainerView.content = (titleText, nil)
  }
}

Subclassing gives me this error:

Any other way to do this? Thanks!

Hi @glennposadas!

Keep in mind we have 2 headers, the ChatThreadHeaderView and ChatChannelHeaderView. In the first snippet, you are changing the ChatChannelHeaderView and in the second one, you are changing the ChatThreadHeaderView.

Can you show the full message of the compilation error? Does the compilation error happen for ChatChannelHeaderView as well or any other component?

Best,
Nuno

[glennposadas]

Hi @nuno-vieira , thanks for replying. Yes, I am aware of those 2 headers, my bad.
I've moved on past this, btw, so I don't have the full error log. But it's a very common compile-time error, basically it'll happen if your project is Objective-C based, and you have some Swift classes with Stream stuff (e.g. the subclass of ChatThreadHeaderView that I've showed in the previous reply), and then Xcode will attempt to port those Swift classes to Objective-C through the Project-Swift.h file. That's it. Xcode won't be able to find the type ChatThreadHeaderView.

BTW, a side question, can we wrap the chat vc in a navigationController and add a close button at the left bar button items without subclassing? Adding a bar button item doesn't seem to work, I assume it needs a custom component again just like this title customization.

[nuno-vieira]

Hi @glennposadas!

Yes, it looks like it is not possible to subclass swift classes from ObjC, according to the docs: https://developer.apple.com/documentation/swift/migrating-your-objective-c-code-to-swift#:~:text=Because%20you%20can%E2%80%99t%20subclass%20Swift%20classes%20in%20Objective%2DC

Unfortunately, currently, the UI SDK relies a lot on subclassing, so it could be difficult to use it in an ObjC project indeed.

can we wrap the chat vc in a navigationController and add a close button at the left bar button items without subclassing

Because of this ObjC limitation, it is better that you handle navigation in your app and don't rely on Stream's Routers. You can use the ChatChannelVC directly and the navigation pattern that you want. But if you are using ChatChannelListVC then it is more difficult, since you can't subclass ChatChannelListVC nor the ChatChannelListRouter. So for now, it looks like your only option is to not use the Channel List component, and build it your self :/

[nuno-vieira]

Hi @glennposadas!

You can also make the subclasses in Swift, and then use them in your Objc code. Any reason why you could not do this?

Best,
Nuno

Hi @nuno-vieira . Thank you for your suggestion. You're a life saver. Actually, I thought this wouldn't work. I mean this didn't work at first. I don't know, I can't remember, but it gave me a lot of errors and I remember experiencing a kind of "loop" when importing Objective-C codes to Swift and vice-versa, therefore my attempt to subclassing the sdk's Swift codes wasn't successful at that time. Anyway, yeah, it works now. Subclass in Swift, then use it in my Objc classes.

Case closed!
