uicolor - Swift- animate CAshapeLayer stroke color -

-

am

I tried to find a way to stroke that I make 

 color conscious I  circleLayer = CAShapeLayer () circleLayer.path = circlePath.CGPath circleLayer.lineCap = kCALineCapRound circleLayer.fillColor = UIColor.clearColor (). Fill CGColor CABasicAnimation = CABasicAnimation CircleLayer.strokeColor = UIColor (red: 0.4, green: 1.0, blue: 0.2, alpha: 0.5) .cg collar layer.lengthwidth = 20.0; circleLayer.lineJoin = kCALineJoinRound // Add circleLayer do not start circleLayer.strokeEnd = 0.0 // sublayers visual layer layer.addSublayer (circleLayer) circle

What is the I want while it is being built (I'm making over a period of 1 second), the color will enliven themselves

Enjoy explored solutions. You definitely take a CAShapeLayer: 

  to animcolor = CABasicAnimation (keypath: "strokeColor") animcolor.fromValue = UIColor.greenColor () CGColor animcolor.toValue = UIColor.orangeColor () .. CGColor animcolor.duration = 1.0; Animcolor.repeatCount = 0; animcolor.autoreverses = true circleLayer.addAnimation (animcolor, forKey: "strokeColor")

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...
