objective c - Parse string and NSLog array -

-

Good day!

I tried to parse the string with such a format: 

  {"code": 200, "serviceID": "53d22b10e46a5", "sender" : 1, "hapier": 0}   
 code:  
  NSString * strData = [[NSString alloc] initWithData: returndata encoding: NSUTF8StringEncoding]; NSR explorer range = nsmkrange (0, [length of strudata]); NSLog (@ "data from server =% @", strData); NSError * Error = Zero; NSRGular Execution * Rezx = [NSGruler Expression Regular Expression with Partarton: @ "(\ w +)? ([0- 9])" Options: 0 Error: and Addition; NSArray * matches = [regex matchesInString: strData options: 0 category: search range]; NSLog (@ "Content of the content is% @", matches);   
 and the last  NSLog  is the content of the next  
  arry ("Show & lt; NSSimpleRegularExpressionCheckingResult: 0x71a9e90 & gt; {8, 1} {É Nsregularekspression: 0x71a4370 & gt; (and +)? ([0- 9]) 0x0} "," & lt; Nsimpleregularekspressionchekingresult: 0x71a9d70 & gt; {9, 1} {& lt; Nsregularekspression: 0x71a4370 & gt; (and +)? [0- 9]) 0x0} "," & lt; Nsimpleregularekspressionchekingresult: 0x71a9d90 & gt; {10, 1} {É Nsregularekspression: 0x71a4370 & gt; (and +) ? ([0- 9]) 0x0} "," & lt; Nsimpleregularekspressionchekingresult: 0x71a9c80 & gt (25) ([0- 9]) 0x0} "," & lt; Nsimpleregularekspressionchekingresult: 0x71a3460 & gt; {28, 1} {É Nsregularekspression: 0x71a4370 & gt; (and +)? ([0- 9]) 0x0} "," & lt; Nsimpleregularekspressionchekingresult: 0x71aa380 & gt; {29, 1} {É Nsregularekspression: 0x71a4370 & gt ; (W +)? ([0- 9]) 0x0} "," & lt; NSSimpleRe GularExpressionChe CkingResult: 0x71aa3a0 & gt; {31, 1} {& lt; NSRegularExpression: 0x71a4370 & gt; (W +)? ([0- 9]) 0x0} "," & lt; NSSimpleRegularExpressionCheckingResult: 0x71a9770 & gt; {32, 1} {& lt; NSRegularExpression: 0x71a4370 & gt; (W +)? ([0- 9]) 0x0} "," & lt; NSSimpleRegularExpressionCheckingResult: 0x71a3440 & gt; {34, 1} {& lt; NSRegularExpression: 0x71a4370 & gt; (W +) ([0-9]) 0x0} "," & lt; NSSimpleRegularExpressionCheckingResult: 0x71a9790 & gt; {35, 1} {& lt; NSRegularExpression: 0x71a4370 & gt; (W +) ([0-9]) 0x0} "," & lt; NSSimpleRegularExpressionCheckingResult: 0x71aa320 & gt; {37, 1} {& lt; NSRegularExpression: 0x71a4370 & gt; (W +) ([0-9]) 0x0} "," & lt; NSSimpleRegularExpressionCheckingResult: 0x71aa340 & gt; {49, 1} {& lt; NSRegularExpression: 0x71a4370 & gt; (W +) ([0-9]) 0x0} "," & lt; NSSimpleRegularExpressionCheckingResult: 0x71a8f30 & gt; {61, 1} {& lt; NSRegularExpression: 0x71a4370 & gt; (W +)? ([0- 9]) 0x0} ")   
 But I want to parse the information from the server and save it to the array, please tell me my mistake. Thanks!  
 
 
 Your input string looks like JSON, so a regular expression will work better than:  
  NSString * json = @ "{\" code \ ": 200, \" serviceID \ ": \" 53d22b10e46a5 \ ", \" sender \ ": 1, \" hasPair \ ": 0} , NSData * jsonData = [json dataUsingEncoding: NSUTF8StringEncoding]; NSError * Error = Zero; id obj = [NSJSONSerialization JSONObjectWithData: jsonData wik P: 0 error: & amp; error], if (obj) {NSAssert ([isKindOfClass obj [NSDictionary NSDumber *] obj; NSNumber * code = dictObj [@ "code"]; NSString * serviceId = dictObj [@ "serviceID" ]; NSNM * Sender = DictObj [@ "Sender"]; NSNumber * Happier = Decotabose [@ "Happier"];} Other {NSGOG (@ "JSON: Failed to parse% @", [Error localization]]; }

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...
