Description

In DBXConnection.pas for Free Pascal iOS mobile conenctors, calling 'dbxconn.start;' is not needed. We must not call start. It is a bug.

Please see
...\freepascal_ios42\Proxy\DBXConnection.pas
and
...\freepascal_ios50\Proxy\DBXConnection.pas

Note:
NSURLConnection Class Reference
Loading Data Asynchronously
+ connectionWithRequest:delegate:
http://developer.apple.com/library/ios/#documentation/cocoa/Reference/Foundation/Classes/NSURLConnection_Class/Reference/Reference.html
------
Creates and returns an initialized URL connection and begins to load the data for the URL request.
------

Steps to Reproduce:

[DBXConnection.pas]
---------------
...
procedure TDBXConnection.start;
begin
{$IFDEF FPC}
  //dbxconn.start;  // no need to call start, because NSURLConnection has already started network access.

  while (not complete and not cancelled) do
  begin
    NSRunLoop.currentRunLoop.runMode_beforeDate(NSDefaultRunLoopMode,
      NSDate.distantFuture);
  end;
{$ENDIF}
end;

function TDBXConnection.InitWithRequest_returningResponse_error_usingDelegate
...
begin
...
...
    dbxconn := NSURLConnection.connectionWithRequest_delegate(request, self);
...
...
end;
...
