i new ios want display response post in alert view.in nslog showed response. need when clicked button alert view can display response.

coding:

-(void) senddatatoserver : (nsstring *) method params:(nsstring *)str{       nsdata *postdata = [str datausingencoding:nsasciistringencoding allowlossyconversion:yes];     nsstring *postlength = [nsstring stringwithformat:@"%lu", (unsigned long)[str length]];      nsmutableurlrequest *request = [[nsmutableurlrequest alloc] initwithurl:[nsurl urlwithstring:url]];     nslog(@"%@",str);      [request sethttpmethod:@"post"];     [request setvalue:postlength forhttpheaderfield:@"content-length"];     [request sethttpbody:postdata];      nsurlconnection *theconnection = [nsurlconnection connectionwithrequest:request delegate:self];      if( theconnection ){          mutabledata = [[nsmutabledata alloc]init];     } } 

alerview:

- (ibaction)butt1:(id)sender {      uialertview *alert = [[uialertview alloc] initwithtitle:@"value"                                                     message:@"%@"                                                    delegate:self                                           cancelbuttontitle:@"cancel"                                           otherbuttontitles:@"ok", nil];      [self senddatatoserver :@"post" params:str];      [alert show];  } 

post method delegates: here response in json111 showed in nslog in alert view failed

-(void) connection:(nsurlconnection *)connection didreceivedata:(nsdata *)data {     [mutabledata appenddata:data]; }  -(void) connection:(nsurlconnection *)connection didfailwitherror:(nserror *)error {     return; }  -(void)connectiondidfinishloading:(nsurlconnection *)connection {       nserror* error111;    json111 = [nsjsonserialization jsonobjectwithdata: mutabledata                                            options:kniloptions                                              error:&error111];     nslog(@"%@",json111);    }   [![emptyvalue in alertview][1]][1]
