App Crashed with the custom View

shivam27saini · March 2, 2021, 12:42pm

I’ve made the custom view to render the participant videos but, when I join the meeting I get this error **Terminating app due to uncaught exception 'NSGenericException', reason: 'This coder requires that replaced objects be returned from initWithCoder:'**

I’m using version v5.4.54802.0124 Xcode 12.4 and iOS 14.4

Hi @shivam27saini, thanks for using our SDK.

Sorry to hear you’re running into a crash with the SDK. Can you please provide the SDK logs from your app so that we may investigate further? The log file should be encrypted.

Thanks!

Hey @shivam27saini,

In addition to the logs, can you also provide your ViewController code?

Thanks!
Michael

Hey @shivam27saini,

Thank you for providing that.
The line:
let activeVideo = MobileRTCVideoView(frame: CGRect.zero)
Is setting the videoView to have no size. This is probably unrelated to your crash, but if it isnt, it may also cause the video to not show. I also noticed this view is never used again outside of viewDidLoad().

The view:

@IBOutlet weak var participantView: MobileRTCVideoView!

Was never told what aspectRatio to follow. You need to call participantView.setAspectRatio() at some point to inform the video view what the aspect will be.

This code

func onSinkMeetingActiveVideo(_ userID: UInt) {
    DispatchQueue.main.async {
        self.participantView.showAttendeeVideo(withUserID: userID)
    }
}

func onSinkMeetingVideoStatusChange(_ userID: UInt) {
    DispatchQueue.main.async {
        self.participantView.showAttendeeVideo(withUserID: userID)
    }
}

Can probably be removed. You do need to call showAttendeeVideo(withUserID: userID) at some point, but not in these callbacks. Calling these here, will cause the participantView to attempt to render a new User video stream every time there is a change in someones video status or if the active speaker changes.

Let me try to assist with your scenario. Are you trying to have 1 main video video that will show a specific user the whole time, or are you trying to have 1 main video view that will show the active user’s video?

Thanks!
Michael

I’ve just checked that the SDK is not initialised

let context = MobileRTCSDKInitContext()
context.domain = “zoom.us”
context.enableLog = true
let sdkInitializedSuccessfully = MobileRTC.shared().initialize(context)

sdkInitializedSuccessfully is returned as false every time, any suggestions what could cause this?

Hey @shivam27saini,

Hmm that is strange. The only time I have seen this happen is when the frameworks have been imported incorrectly. Where are you calling that code?

Thanks!

Hey @shivam27saini,

You are getting a EXC_CORPSE_NOTIFY exception which is likely a language exception or a missing framework. Apple Developer Documentation

Base on this exception and our previous conversation, I do not think the MobileRTC.framework was imported into your application correctly. I would suggest removing the framework and re-importing it again using these steps: https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/getting-started/integration.

You will know that the framework is imported correctly when MobileRTC.shared().initialize(context) returns true.

Thanks!
Michael
