swift - iOS:is that available to control or choose the way to receive message from network? -

-

For example, I want to force the device to get data from the network with 3G / 4G service when WiFi is connected. What is the permissions / APIs of developers that which network device should be used? Is there any document about this in the Apple Developer Library?

Use the richness class to search Google.

Richability * Accessibility = [Reachability Possibility for Internet Connection]; [Accessibility StartNotifier]; NetworkStats position = [reachability current resheability credits]; If (position == ReachableViaWiFi) {}

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
