ios - While setting NSString to NSURL, NSURL is returning nil value -


i have parse return of json api i've taken url string , after passed nsurl in nslog showing nil. here code,

nsstring *urlstring=[nsstring stringwithformat:@"http://api.v3.factual.com/t/places?q=%@&geo={\"$circle\":{\"$center\":[19.9909631,73.8034808],\"$meters\":40000}}&limit=20&key=123456",[self.strurl lowercasestring]]; nsurl *url=[[nsurl alloc]initwithstring:urlstring ]; nsurlrequest *req = [nsurlrequest requestwithurl:url];

thanks in advance.

you must encode url contains special characters, try this

nsstring *paramstring=[nsstring stringwithformat:@"/t/places?q=%@&geo={\"$circle\":{\"$center\":[19.9909631,73.8034808],\"$meters\":40000}}&limit=20&key=123456",[self.strurl lowercasestring]];  nsstring *encodedsearchstring = [paramstring stringbyaddingpercentescapesusingencoding:nsutf8stringencoding];  nsstring *urlstring = [nsstring stringwithformat:@"http://api.v3.factual.com%@", encodedsearchstring]; nsurl *url = [nsurl urlwithstring:urlstring]; nslog(@"urlstring %@",url)

hope helps

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 .
