objective c - AFJSONRequestSerializer POST JSON Array -

-

I am trying to post to the API which is expecting the JSON array as input, for example For: [["token": "bd3", "display_order": 0}] I get the AFJSONRequestSerializer to get this build up: Unable to create parameter, my code: 

  NSDictionary * campParams = @ {@ "token": @ "bd3", @ "display_order": @ "0"}; NSArray * arr = [NSArray arrayWithObject: campParams]; NSDictionary * Final = [object with NSDictionary dictionary: arr forKey: @ ""];   
 that creates JSON:  
  {"": [{"token": "bd55", "display_order": "0"}]}   
 How do I modify my code to get the proper JSON output? I am making a second dictionary as AFHTTPRequestOperationManager accept the parameter as a dictionary, not an array  
  [keep the manager. Url parameter: Final success: ^ (AFHTTPRequestOperation * operation, id responseObject) {/ Done} failure: ^ (FTPTRAQ operation operation *, NSERR * error) {NSLog (@ "error:% @", error); }];    
 
 
 The last dictionary does not add actions, the question tells if a JSON array is expected. .  
  NSArray * jsonArray = @ [@ {@ "Tokens": @ "BD3", @ "Display_order": @ "0"}]; NSError * error; NSDTA * JSNETActa = [NSJSNASSArailization DatavidjisonAbject: JasonArere Option: 0Error: and Error]; NSLog (@ "String as JSNDTTA:% @", [[NSSTING ALLOC] Init Withdata: JSNET Encoding: NSTF 8 string encoding]);   
 Output:  
  as jsonData string: [["token": "bd3", "display_order": "0"}]   
 There is a possibility that the last argument number should be, no string:  
  NSArray * jsonArray = @ [@ {@ "token": @ "BD3 ", @" Display_order ": @ 0}];   
 Production:  
  jsonData as string: [{"token": "BD3", "display_order": 0}]  am  
 which better matches your initial JSON example  
 here's an example but AFNetworking not use because I do not proficient in it :.  
  NSMutableURLRequest * Request = [NSMutableURL request request withURL: url]; [Request set httpbb: jssadata]; [Set http system: @ "post"]; [NSURLConnection sendAsynchronousRequest: Request line: [NSOperationQueue currentQueue] completionHandler: ^ (NSURLResponse * reaction, NSData * data, NSError * connectionError) {if (connectionError) {NSLog (@ :, "Error% @" connectionError); } Other {Anselog (@ "data as a string:% @", [[Ansstiing Elok] Init Waitdeta: Data Encoding: Anstif 8 string encoding]); }}];   
 Note: Use AFNetworking in all ways, it's great! I just knew old OSX / IOS methods and I did not have a test project that had already installed Air Force.

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...
