Obj-cからPHPへPOSTするための変数はありません

Question

こんにちは、iOSとXcodeの初心者ですが、ログイン画面を作れば、ログイン画面は何も応答しません。

- (IBAction)btnLogin:(id)sender { 


    NSInteger success = 0; 
    @try { 

     if([[self.insUsuario text] isEqualToString:@""] || [[self.insSenha text] isEqualToString:@""]) { 

      [self alertStatus:@"Insira o email e a senha!" :@"Erro" :0]; 

     } else { 
      //ViewPontos *WP = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewPontos"]; 
      //WP.gUser = self.insUsuario.text; 

      NSString *post =[[NSString alloc] initWithFormat:@"usuario=%@&senha=%@",[self.insUsuario text],[self.insSenha text]]; 

      NSLog(@"PostData: %@",post); 

      NSURL *url=[NSURL URLWithString:@"http://emporio56/apiapp/pegarPontos.php"]; 

      //NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; 
      NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]; 
      NSLog(@"DATA %@", postData); 

      NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; 

      NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
      [request setURL:url]; 
      [request setHTTPMethod:@"POST"]; 
      [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; 
      [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
      //[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 
      [request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
      [request setHTTPBody:postData]; 
      [request setHTTPShouldHandleCookies:YES]; 

      NSLog(@"%@", request); 

      NSURLConnection *conn= [[NSURLConnection alloc]initWithRequest:request delegate:self]; 
      if(conn) 
      { 

       NSError *error = [[NSError alloc] init]; 
       NSHTTPURLResponse *response = nil; 
       NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; 
       NSLog(@"Response code: %ld", (long)[response statusCode]); 

       if ([response statusCode] >= 200 && [response statusCode] < 300) 
       { 
        //NSString *responseData = [[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding]; 
        NSLog(@"Response ==> %@", response); 

        NSError *error = nil; 
        NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:urlData options:NSJSONReadingMutableContainers error:&error]; 
        success = [jsonData[@"success"] integerValue]; 
        NSLog(@"Success: %ld",(long)success); 

        if(success == 1) 
        { 
         NSLog(@"Login SUCCESS"); 
        } else { 

         NSString *error_msg = (NSString *) jsonData[@"error_message"]; 
         [self alertStatus:error_msg :@"Erro" :0]; 
        } 

       } else { 
        //if (error) NSLog(@"Error: %@", error); 
        [self alertStatus:@"Erro!" :@"Sign in Failed!" :0]; 
       } 


       NSLog(@"Conectado"); 
      } 
      else 
      { 
       NSLog(@"Nao conectou"); 
      } 
      //[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]]; 
     } 
    } 
    @catch (NSException * e) { 
     NSLog(@"Exception: %@", e); 
     [self alertStatus:@"Sign in Failed." :@"Erro" :0]; 
    } 
    if (success) { 
     [self performSegueWithIdentifier:@"login_success" sender:self]; 
    } 
} 

    - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { 
     // A response has been received, this is where we initialize the instance var you created 
     // so that we can append data to it in the didReceiveData method 
     // Furthermore, this method is called each time there is a redirect so reinitializing it 
     // also serves to clear it 
     _responseData = [[NSMutableData alloc] init]; 
    } 

    - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { 
     // Append the new data to the instance variable you declared 
     [_responseData appendData:data]; 
    } 

    - (NSCachedURLResponse *)connection:(NSURLConnection *)connection 
         willCacheResponse:(NSCachedURLResponse*)cachedResponse { 
     // Return nil to indicate not necessary to store a cached response for this connection 
     return nil; 
    } 

    - (void)connectionDidFinishLoading:(NSURLConnection *)connection { 
     // The request is complete and data has been received 
     // You can parse the stuff in your instance variable now 

    } 

    - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { 
     // The request has failed for some reason! 
     // Check the error var 
    } 

ユーザ名とパスワードをテストして置くためのコードを実行して、私はそのいつもresponse = (null)サーバからの応答を得ることはありません後、誰かが私はそれを修正するために何ができるか知っていますか？私はあなたがウェブで見つけることができるコードの大部分を試して、それは人々が言う方法、同様に動作しませんでしたので、私はアンドロイドアプリケーションを接続するために同じPHPを使用していますが、 PHPのユーザ名とパスワードをPOSTし、dbに接続します。

問題のため申し訳ありません

が、私は

が起こっているかわからない、これを試してみてください。あなたの問題を解決することを願っています。

NSString *stringUrl = [NSString stringWithFormat:@"http://emporio56/apiapp/pegarPontos.php?usuario=%@&senha=%@",[self.insUsuario text],[self.insSenha text]]; 
    NSURL *url = [NSURL URLWithString:stringUrl]; 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
    [NSURLConnection sendAsynchronousRequest:request 
             queue:[NSOperationQueue mainQueue] 
          completionHandler:^(NSURLResponse *response, 
               NSData *data, NSError *connectionError) 
    { 
     if (data.length > 0 && connectionError == nil) 
     { 
      NSDictionary *dicYourResponse = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL]; 
      NSLog(@"%@",dicYourResponse); 
     } 
    }];
