ios - How Do I save the user's image fetched from fbprofilepictureview using the Facebook SDK -


so i'm implementing facebook login button in ios app i'm working on, i'm trying save user's profile picture that's accessed using line; 

self.profilepicture.profileid = user.id;

i haven't had luck storing image use elsewhere in app. have tried number of methods including approach

imageurl=[nsstring stringwithformat:@"https://graph.facebook.com/%@/picture?redirect=true", user.username];

any welcome!

you need use user.objectid , not user.username.

you can use drop-in replacement fbprofilepictureview, dbfbprofilepictureview. exposes imageview readonly property. using that, code this...

self.profilepicture.completionhandler = ^(dbfbprofilepictureview* view, nserror* error){     if(error) {         view.showemptyimage = yes;         nslog(@"loading profile picture failed error: %@", error);     } else {         uiimage *image = view.imageview.image;         nsdata *imagedata = uiimagepngrepresentation(image);         [imagedata writetofile:filename atomically:no];     } };

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 .
