flow of method must *run 1st url --> generate response ({userid:"20",message:"success"} ) --> run 2nd url *

help me, in advance everyone.

you can call second method respect response of first method

-(void)webservicecall {     webapicontroller *obj=[[webapicontroller alloc]init];      nsmutabledictionary *imageparameter = [nsmutabledictionary dictionary];      nsdata *imagedata = uiimagepngrepresentation(self.productimageview.image);      [imageparameter setvalue:imagedata forkey:@"image"];      [obj callapiwithimage:@"upload.php" withimageparameter:imageparameter withoutimageparameter:nil successcallback:@selector(upload_response:response:) anddelegate:self];  } 

response web service:

-(void)upload_response:(nsstring *)apialias response:(nsdata *)response {      nsmutabledictionary *jsondictionary=[nsjsonserialization jsonobjectwithdata:response options:nsjsonreadingmutablecontainers error:nil];      nsstring *responsemsg=[[nsstring alloc] initwithstring:[jsondictionary objectforkey:@"message"]];      if ([responsecode isequaltostring:@"success"]) {         [self calltosecondwebservice];      }  } 

second webservice:

-(void)calltosecondwebservice {  }
