Opentok black screen issue

Question

I am using Opentok code for my swift program. I have two questions.

1) I use same session in my two UIViewcontrollers. Once I open my connection with the session, should I close it before opening /connecting it in the second page?

2) sometime I am getting black screen insead of subscribers video. I use the static session created in the trial version.

Please advice.

have you testing on real devices or simulater? because simulater have no camera. — Varinder Singh iPhone Dev, Jul 18 '17 at 08:02
two reasons for black screen.... 1. because of internet 2. if your Session is expired — Varinder Singh iPhone Dev, Jul 18 '17 at 09:11
1. I have a reliable net connection 2. Session is till there. But one question I have selected the media mode option as Routed, not as Relayed. I need this app for 1-1 chat. Will this be an issue? also this happens not every time.... — Vinod, Jul 18 '17 at 09:29
Relayed type is not supported group video calling... Routed is for group and 1 -1 chat both. I am using Routed and its working fine — Varinder Singh iPhone Dev, Jul 18 '17 at 09:34
Ok, can you please tell whether I have to close the connection while I enter to a new window, or without closing again call doconnect() — Vinod, Jul 18 '17 at 09:49

var error: OTError? = nil
session.disconnect(error)
if error != nil {
print("disconnect failed with error: (\(error))")
}
session(session, streamDestroyed: stream)

call this in viewWillDisappear ? – Vinod Jul 18 '17 at 09:55
Ok, I shall try this. – Vinod Jul 18 '17 at 10:07
This code throws two errors. 1) Cannot invoke 'disconnect' with an argument list of type '(OTError?)' 2) Cannot call value of non-function type 'OTSession' --- here is my class https://github.com/opentok/opentok-ios-sdk-samples-swift/blob/master/Basic-Video-Chat/Basic-Video-Chat/ViewController.swift – Vinod Jul 18 '17 at 10:23
