Reconnecting State and Callbacks

TVOCallStateReconnecting is provided as a new Call state. A callback call:isReconnectingWithError: corresponding to this state transition is triggered when a network change is detected when Call is already in the TVOCallStateConnected state. If the Call is in TVOCallStateConnectingor in TVOCallStateRinging state when network change happened, the SDK will receive the call:didFailToConnectWithError: callback with the TVOErrorConnectionError error (31005). If a Call is reconnected after reconnection attempts, the application will receive the callDidReconnect: callback and the Call state transitions to TVOCallStateConnected.

Updates:

typedef NS_ENUM(NSUInteger, TVOCallState) {
    TVOCallStateConnecting = 0, ///< The Call is connecting.
    TVOCallStateRinging,        ///< The Call is ringing.
    TVOCallStateConnected,      ///< The Call is connected.
    TVOCallStateReconnecting,   ///< The Call is reconnecting.
    TVOCallStateDisconnected    ///< The Call is disconnected.
};

@protocol TVOCallDelegate <NSObject>

@optional
- (void)callDidStartRinging:(nonnull TVOCall *)call;
- (void)call:(nonnull TVOCall *)call isReconnectingWithError:(nonnull NSError *)error;
