Difficulty trying to split a string in swift -


i have issue in swift when trying split bizzare string in swift

the string is:

qwerty.mapview

37.33233141 -122.0312186

tyrewq.mapview

37.33233141 -122.0312

how should if try make this

qwerty.mapview 37.31 -122.031

tyrewq.mapview 37.33 -122.032

i tried things hit issue because of starting string having \n after each word

i did tests in playground. following code should want. can write shorter, better explanation split every command 1 line..

var numberformatter = nsnumberformatter() numberformatter.maximumfractiondigits = 3 // on number formatter can define desired layout  var teststring = "qwerty.mapview\n37.33233141 -122.0312186"  var splitbynewline = teststring.componentsseparatedbystring("\n") var splitbyspace = splitbynewline[1].componentsseparatedbystring(" ") var nsstringlongitude = nsstring(string:splitbyspace[0]) var longitude = nsstringlongitude.floatvalue  var nsstringlatitude = nsstring(string:splitbyspace[1]) var latitude = nsstringlatitude.floatvalue   var formattedlongitude = numberformatter.stringfromnumber(longitude) var formattedlatitude = numberformatter.stringfromnumber(latitude)  var finaloutput = "\(splitbynewline[0]) \(formattedlongitude) \(formattedlatitude)"

i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
