        nslog(@"response : %@",returnstring);          if([returnstring isequaltostring:@"success ! file has been uploaded"])         {             uialertview *alert = [[uialertview alloc] initwithtitle:@"success" message:@"image saved successfully" delegate:self cancelbuttontitle:@"ok" otherbuttontitles:nil];              [alert show];         }         nslog(@"finish"); 

can body tell me mistake in code. have enter parameters compulsary caption, user_id, mobile_tauky_id, blauky_id, image, audio

i using asiformdatarequest same, working fine , give response in seconds.

uiimage * img = [uiimage imagenamed:@"elephant.jpg"]; nsdata *imagedata = uiimagepngrepresentation(img);  nsstring *strurl =your url"; asiformdatarequest *request = [asiformdatarequest requestwithurl:[nsurl urlwithstring:strurl]]; [request setdelegate:self]; [request setpostvalue:@"avanvsj767uysuyas" forkey:@"imei"]; [request setpostvalue:cardname forkey:@"customername"]; [request setpostvalue:@"varun@gmail.com" forkey:@"customeremailid"]; [request adddata:imagedata withfilename:@"image" andcontenttype:@"image/png" forkey:@"filename1"]; [request setdelegate:self]; [request startasynchronous];
