CBCentralManager does not detect nearby Bluetooth devices. 

  - (zero) viewDidoadload {[Super Viewedload]; _centralManager = [[CBCentralManager alloc] initWithDelegate: self queue: zero]; _data = [[NSMUtableData Allok] Init]; } - (Zero) Central ManagerED update: (CBC Central Manager) Central {if (central .state == CBCEntertainmentPoideon) {NSDictionary * options = @ {CBCentralManagerScanOptionAllowDuplicatesKey: @NO}; [_centralManager scanForPeripherals with services: zero option: option]; NSLog (@ "Scanning Started"); } If (central.state == CBCentralManagerStateUnknown) {NSLog (@ "CBCentralManagerStateUnknown"); } If (CentralStat == CBCEntryManagerState Resetting) {NSLog (@ "C CB Central Manager Setting"); } If (central .state == CBCentralManagerStateUnsupported) {NSLog (@ "CBCentralManagerStateUnsupported"); } If (CentralStat == CBCEnmentalManagerState unauthorized) {NSLog (@ "CBCEntrealManagerStateUnited"); } If (CentralStat == CBCEnmentalGeneratePoideOff) {NSLog (@ "CBCEnTermNestAstertPaidOf"); }}

I have checked that state CBCentralManagerStatePoweredOn

after that it does not call representative's methods.

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...
