swift - Change Border Width of UISegmentedControl in iOS 8 -

-

How do I change the boundary width of a UISegmentedControl in iOS 8? Currently, the border width is 2px, and I would like to set it to 1px. CALayer did not work to determine border width. I can not find anything about it

Thanks in advance for any help!

I recommend you to use custom splitter images based on your needs: 

  [mySegmentedControl setDividerImage: Image 1 forLeftSegmentState: UIControlStateNormal rightSegmentState: UIControlStateNormal barMetrics: barMetrics]; [MySegmentedControl setDividerImage: Image 2 forLeftSegmentState: UIControlStateSelected rightSegmentState: UIControlStateNormal barMetrics: barMetrics]; [MySegmentedControl setDividerImage: Image 3 forLeftSegmentState: UIControlStateNormal rightSegmentState: UIControlState Selected Barometrics: Barometrics];

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...
