ios - webview won't load with string -

-

Viewdidload in my webview I am implementing the following code The problem is that when I include NSString * encodedString, the webview Will not be visible. I have a search string with spaces and sometimes. Any ideas about what's going on here? 

  NSString * urlString = [NSString stringWithFormat: @ "http://google.com?q=%@", search-string]; NSString * encodedString = CFBridgingRelease (CFURLCreateStringByAddingPercentEscapes (NULL, (CFStringRef) urlString, NULL, (CFStringRef) @ "! * '() :: @ and = + $, /?% # []", KCF string encodingTTF 8)); NSLog (@ "searchstressing% @", searchstress); NSURL * myURL = [NSURL URLWithString: EncodedString]; NSURLRequest * myRequest = [NSRR request request with url: myURL]; [Load webload load: myRequest];   
 What will happen to Google's first page results for this search string?   
 
 
 try it  
  NSString * urlString = [NSString stringWithFormat: @ "Http://www.google.com/search?q=%@", search-string]; UrlString = [URL string stringErdringPrint escapes using encoding: NSUFF 8 string encoding]; NSURL * myURL = [NSURL URLWithString: urlString]; NSURLRequest * myRequest = [NSRR request request with url: myURL]; [Load webload load: myRequest];

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...
