refreshCarrierToken()
Attempts to refresh the carrier token.
Declaration
func refreshCarrierToken() -> BoolReturn Value
true if the system performs a token refresh in response to this call; otherwise, false.
Discussion
Call this method to update the carrierToken when the token exists but the server rejects it.
Inspect the return value to determine whether this call results in an actual refresh. If the return value is true, the system attempts the refresh and calls the delegate method subscriberTokenRefreshed(_:). A return value of false indicates an invalid argument (such as bad carrier descriptors or service descriptor) or that the subscriber doesn’t support the authentication action.
