objective c - When do we use self. or [self ] in stringWithFormat? -


when using stringwithformat nsstring in return statement when use self. ; [self ] or instance?

for example, have return [nsstring stringwithformat:@"%@ %@" , self.someinstance or [self someinstance] or someinstance].

self.someinstance equivalent [self someinstance]. former using dot-syntax became available in objective-c 2.0.

it's personal preference option use. suggest being consistent throughout app , use 1 format.

using someinstance on own, without self. or [self ], different , accesses instance variable directly. should avoided outside of init methods.

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 .
