Navigation: Create RoomCoordinator

[SBiOSoftWhare]

To make screen reusable and take back control on navigation we need to manage all the things listed below outside of RoomViewController:

Priority:

• Show a room: [[AppDelegate theDelegate] showRoom:room.roomId andEventId:nil withMatrixSession:self.mainSession];
• Handle universal link: [[AppDelegate theDelegate] handleUniversalLinkURL:url]; & [[AppDelegate theDelegate] handleUniversalLinkFragment:fragment fromURL:url];
• Start a direct chat [[AppDelegate theDelegate] createDirectChatWithUserId:matrixId completion:completion];
• Leave the room [[AppDelegate theDelegate] restoreInitialDisplay:^{}];

Todo next:

• Present complete security: [[AppDelegate theDelegate] presentCompleteSecurityForSession: self.mainSession];
• Show room infos: - (void)showRoomInfoWithInitialSection:(RoomInfoSection)roomInfoSection
• Show room creation: - (void)showRoomCreationModalWithBubbleData:(id<MXKRoomBubbleCellDataStoring>) bubbleData
• Show member details: - (void)showMemberDetails:(MXRoomMember *)member
• Show emoji picker: - (void)reactionsMenuViewModelDidTapMoreReactions:(ReactionsMenuViewModel *)viewModel forEventId:(NSString *)eventId
• Show edit history: - (void)showEditHistoryForEventId:(NSString*)eventId animated:(BOOL)animated
• Show media picker: - (void)showMediaPickerAnimated:(BOOL)animated
• Show sticker picker: - (void)roomInputToolbarViewPresentStickerPicker
• Show room search: if ([[segue identifier] isEqualToString:@"showRoomSearch"])
• Show contact details: [[segue identifier] isEqualToString:@"showContactDetails"])
• Show unknown devices: ([[segue identifier] isEqualToString:@"showUnknownDevices"])

Nice to have:

• Jitsi call management: [[AppDelegate theDelegate].callPresenter displayJitsiCallWithWidget:jitsiWidget]; & [[AppDelegate theDelegate].callPresenter endActiveJitsiCall];
• Missed discussion counts
  • Missed discussion count [[AppDelegate theDelegate].masterTabBarController missedDiscussionsCount];
  • Missed highlighted discussion count : missedHighlightDiscussionsCount
• Show error as alert: [[AppDelegate theDelegate] showErrorAsAlert:error];
• Show alert with title: [[AppDelegate theDelegate] showAlertWithTitle:title]
• Visible room id: [AppDelegate theDelegate].visibleRoomId = self.roomDataSource.roomId;
• Last navigated room id from push: lastNavigatedRoomIdFromPush
