ios - Transferring the same object between ViewControllers -


i have class, user, has nsmutablearray stores custom nsobjects. want 1 of these ever instantiated throughout entire app, , able call methods on in each viewcontroller getting , setting. problem don't know how call methods apply 1 instance, instead of creating new 1 each time. i'm new objective-c, learning curve makes me feel i'm missing bit obvious. i've been working on day , @ wit's end. there solution dilemma? should use singleton class?

(if helps, class user class stores to-do list each user uses app. custom nsobjects to-do items. there's better storage method should used here, i'm not sure is.)

randompleb sounds you're looking singleton. http://en.wikipedia.org/wiki/singleton_pattern. think question has been answered before search around on so.

laymen's terms; create static reference class want 1 of inside class, make static method in following way:

//call classes want modify  public static getsharedinstance() {     if(the static instance of class not exist){         instantiate instance;     }  return classes static instance.. }

hope helps (and if wrong, hope can correct me)

also in regards storing objects, think nsmutablearray fine unless big persistent list each task has many properties in case maybe using coredata better.

javascript - Highcharts multi-color line -

Image
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 .
