json - calling method webService (WCF) from iOS objective C) -

i want calling method webservice parameter json ios, received error.

code server side (wcf):

[operationcontract]     [webget(responseformat = webmessageformat.json, uritemplate = "/test/{input}")]     int test(string input); 

i want input (parameter method , url) = typeof (json)

code client side (ios-objective c) :

nsstring *json = [self converttojson:myobject]; nsstring *urlcomplete = [nsstring stringwithformat:@"%@%@",@"http://test.com/service.svc/test/",json];      urlcomplete = [urlcomplete stringbyaddingpercentescapesusingencoding:nsutf8stringencoding];      nsmutableurlrequest *request = [[nsmutableurlrequest alloc]init];      [request seturl:[nsurl urlwithstring:urlcomplete]];     [nsurlconnection sendasynchronousrequest:request queue:[nsoperationqueue mainqueue] completionhandler:              ^(nsurlresponse *response, nsdata *data, nserror *connectionerror) {                  if (data.length > 0 && connectionerror == nil) {                      nsstring *string = [[nsstring alloc]initwithdata:data encoding:nsasciistringencoding];                      nslog(@"data recived:\n %@",string);                  }                  else{                      nslog(@"error %@",[connectionerror description]);                  }              }]; 

the webservice being tested windowsphone , returns ok doesn't work ios. please me! thanks:)

error description "http error 400. request url invalid." clears url passing incorrect. please cross check windows team if appending json url.

generally, if want post data can set requestdata json , go either put or post request instead of request.
