Unity3D demo on iPhone cannot receive udp packets -


I wrote an udp and received the unity3d plugin dll in C #, but it received no udp packet from the server of iphone4 can not do.

When the server sends an IWP packet to the demo running on the iPhone 4, then it can not get anything.

When the server sends a UDP packet on the demo running on iPod Touch 4, then it works! a packet!

When Unity submits the udp packet to the server running the demo in 3D editor, then it works fine!

I used Wirehaarck to capture the packet between the client and the server 

  Internal class RudpNetInteractor {Personal socket socket;  
 Why?  
 Why? Private endow server server; Internal Roodnet Interactor (IPEdpoint Server Address) {this.rudpClient = rudpClient; This.serverAddress = serverAddress; } Internal Zero Build Connection () {Socket = New Socket (Address Family.Inter Network, SocketType.Dgram, ProtocolType.Udp); Socket.Connect (serverAddress); BeginReceive (); } Send internal zero (byte [] buffer) {socket.Begin.Send (buffer, 0, buffer length, socketflags.None, new async callback (empty), blank); } Private zero hands (IAsyncResult AR) {try {socket.EndSend (ar); } Hold {}} internal zero destruction () {socket.Close (); Socket = null; } Private Zero OnReceive {IAsyncResult AR} {try {SocketReceiveInfo received INFO = (SocketReceiveInfo) AR. Asyncstate; Socket Received Sync = ReceivedInfo Rescue socket; Int len ​​= receive sign Andresave (AR); If (lane and gt; 0) {byte [dest = new byte] [lane]; Array.Copy (receiveInfo.ReceiveBytes, dest, len); Console.WriteLine (BitConverter.ToString (Destination)); } Initial (); } Hold {}} Private Zero BeginReceive () {byte [] receiveBytes = new byte [576]; SocketReceiveInfo info = New Socket ResinVinfo (Receipts, Sockets); Socket.BinrisFForf (Receipts, 0, Receipts, Long, Socketflags, None, Ref Servers, New Async Callback (ONLY), info); }} Internal class SocketReceiveInfo {private byte [] receivedbyte; Private Socket ReceivedSet; Internal SocketReceiveInfo (byte [] received bytes, socket receiptsocket) {this.receiveBytes = receiveBytes; This.receiveSocket = recesocket; } Internal Byte [] Receipts {Receive returns receive; }} Internal socket receiptsocket {Receive {Return ReceiptSocket; }}}

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
