ios - PeerID object received by another peer is different that the original object in MultipeerConnectivity Framework -

-

I am using Multipoint Connectivity Framework I am saving my coworker to reuse it in NSUserDefaults ( As suggested by the apple) in this way (the following code is faster but there is behavior similar to Objective C): 

  var peerId: MCPeerID = {omitted = NSUserDefaults.standardUserDefaults () ; Datatosno = Default Dataforaki ("KPIRID"); Var peer = NSKeyedUnarchiver.unarchiveObjectWithData (dataToShow) as? MCPeerID; If colleague == blue {peer = MCPIRID (display name: uidive courant device).); Give data: NSDT = NKAd Carrier Archived datahop object (peer); Defaults.setObject (data, forKey: "kPeerID"); Defaults.synchronize (); } Println ("I'm a colleague: \ (peer!)"); Return peer!! } ()   
 I send an invitation to the search peer like this:  
  the flash browser (Browser: mcnarbiswrez browser !, found peer pirid: mcpair id! , DiscoveryInfo information with: [NSObject: AnyObject]!) {Println ("\ (self.peerId) found peer (pearID)"); If the browser session = self.session {browserSession.delegate = self; Browser.invitePeer (PRIID, op: browser, contact, zero, timeout: 30); } Other {println ("browser session is zero"); }}   
 Advertiser uses the code:  
  func advertiser (Advertiser: MCNERB Service Provider !, Powered By: PieredID: MCPARID !, Contact With context: NSDTa !, InvitationHandler: ((Bull, MC session!) -> Zero)!) {Println ("Receive invitation from (self .PirID)"); Var session = available session (); InvitationHandler (true, session); }   
 The problem I am facing is: When the advertiser gets a PIRID, it shows a different peer id than the original PIARID, but its correct display name is .  
 The browser console output is:  
  I'm a colleague: & lt; MCPeerID: 0x1663e670 DisplayName = John Yang 'iPad & gt; & Lt; MCPeerID: 0x1663e670 DisplayName = John Yang 'iPad & gt; & Lt; Invitation from MCPeerID: 0x1666 DAF 0 DisplayNenam = John Yang's iPadMoney & gt; & Lt; MCPeerID: 0x1663e670 DisplayName = John Yang 'iPad & gt; & Lt; Connecting to MCPeerID: 0x1666 DAF 0 DisplayName = John Yang's iPad Day & gt; & Lt; MCPeerID: 0x1663e670 DisplayName = John Yang 'iPad & gt; & Lt; Connected to MCPeerID: 0x1666 DAF 0 DisplayName = John Yang's iPadMoney & gt;   
 And the advertiser console output is:  
  I'm a colleague: & lt; MCPeerID: 0x1569d230 DisplayName = John Yang's iPad Day & gt; & Lt; MCPERID: 0x1569d230 displayname = John Yang's iPadMoney & gt; Got colleague & lt; MCPeerID: 0x15586600 DisplayName = John Yang 'iPad & gt; & Lt; MCPERID: 0x1569d230 displayname = John Yang's iPadMoney & gt; & Lt; Connecting to MCPeerID: 0x15586600 DisplayName = iPad of John Yang & gt; & Lt; MCPERID: 0x1569d230 displayname = John Yang's iPadMoney & gt; & Lt; Connected to MCPeerID: 0x15586600 DisplayName = John Yang 'iPad & gt;   
 As you can see, the browser and advertiser have their peerId information, when they are received by other colleagues, then their colleagues are different, can anyone explain this? Is there something that I am doing wrong?   
 
 
  & lt; MCPeerID: 0x1663e670 display name = John Yang's iPad & gt;   
  0x1663e670  indicates the memory address of the  MCPeerID  object on the current device. Do not reference the frame with the actual  MCPeerID  object, as long as it is expected to be  displayName , it is the right colleague.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
