ios - UIPicker single component to display multiple arrays -

-

The first comment, I hope I am doing this right.

Let me have a UIPicker. I am trying to display 2 column data in a single picker component. The reason I have chosen to do this within 1 component is that I want to scroll arrays together, which I can not get many components to do.

There is a problem, I can not get in this way, or to work as a title, the Forrare and the Viewfire will return only one value (according to C's rules). I tried to make them output arrays and decates, but this has caused data type errors. I can work fine using it 1 component, 1 array with View ForRow, but it allows only the entire area to justify, not parts of the string

The code below works great and returns the correct answer with return label 2; ? And right if label1 change to go back, I get how to display both 

  - (UIView *) pickerView: (UIPickerView *) pickerView viewForRow: (NSInteger) line forComponent : (NSInteger) component reusingView: (UIView *) See {UILabel * label1; {Label 1 = [[UILabel alloc] initWithFrame: CGRectMake (10.0F, 150.0F, 130.0F, 60.0F)]; Label1.textAlignment = NSTextAlignmentLeft; Label1.text = [_firstListObjectAntindex: line]; } UILBL * label 2; {Label 2 = [[UILabel alloc] initWithFrame: CGRectMake (100.0f, 10.0f, 175.0f, 100.0f)]; Label2.textAlignment = NSTextAlignmentCenter; Label2.text = [_secondListObjectOntIndex: line]; } Return label 2; }    
 
 
 code your <> UIPickerView  setup for a component.  
 Now, assuming that the same number of two array  _firstList  and  _secondList  objects in them, then you have two options:  
     
  1.  
     Use simple  pickerView: titleForRow: forComponent:  method to build two single string return values:  
      - (NSString *) pickerView: (UIPickerView *) pickerView titleForRow: (NSInteger) line forComponent: (NSInteger) component {return [NSString stringWithFormat: @ "% @ -% @", _firstList [line], _secondList [line]]; }   
     Of course you can format two strings as needed. This is an example   
  2.  
     Use  pickerView :. ViewForRow: forComponent: reusingView:  like you tried but returned the same view connected to that two label.  
      - (UIView *) pickerView: (UIPickerView *) pickerView viewForRow: (NSInteger) line forComponent: (NSInteger) component reusingView: (UIView *) view {UILabel * label1; UILBL * label 2; If (see) {label1 = (UILabel *) [View View Tag: 1]; Label1 = (UILabel *) [View View Tag: 2]; } Else {view = [[UIView alloc] initWithFrame: CGRectMake (0, 0, 320, 40)]; UILBL * label 1 = [[UILBL Alloc] InitVithframe: CGRactMake (10.0F, 0.0F, 130.0F, 40.0F)]; Label1.tag = 1; Label1.textAlignment = NSTextAlignmentLeft; UILBL * label2 = [[UILabel alloc] initWithFrame: CGRectMake (100.0f, 0.0f, 175.0f, 40.0f)]; Label2.tag = 2; Label2.textAlignment = NSTextAlignmentCenter; [Adsview view: label 1] View; [Adsview view: label 2] View; } Label1.text = _firstList [line]; Label2.text = _secondList [line]; Return view; }   
     Note how this properly uses the reuse used.

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...
