cocoa touch - how to hide buttons in objective-c -


so, realize there multiple threads asking type of question, none of them describe kind of error i'm having.

i create variables , set methods in header here:

iboutlet uibutton *buildnewtower; iboutlet uibutton *canceltower;  -(ibaction)buildnewtower:(id)sender; -(ibaction)canceltower:(id)sender;

i call these functions in main class so:

-(ibaction)buildnewtower:(id)sender{ if(credits >= 15){     buildnewtower.hidden = yes;     canceltower.hidden = no;      tower1s.hidden = no;     tower2s.hidden = no;     tower3s.hidden = no;     tower4s.hidden = no;     tower5s.hidden = no;     } }  -(ibaction)canceltower:(id)sender{ buildnewtower.hidden = no; canceltower.hidden = yes;  tower1s.hidden = yes; tower2s.hidden = yes; tower3s.hidden = yes; tower4s.hidden = yes; tower5s.hidden = yes; }

roughly summed up, buildnewtower , canceltower buttons not react .hidden variable inherit. other objects (all imageviews) disappear should.

i'm guessing might buttons , them being hidden?

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 .
