I have 2 subview A and B Place in Scrollview. The first placed in the scrollview and then in the Place BA Subview, Uiimageview B Subview contains only Uttextfield. In a subview, I can upload an image for the gallery. Before uploading the image to UIImagePickerController.I need "A" Subview before uploading the image to uiimageView. No need to show up. U is the first time on uuscrollview. Upload an image comes first on a subview uiimageView and then the B subview is placed. 

  - (zero) viewDidoadload {[Super ViewDidoadload]; Score = [[UIScrollView alloc] init]; Scrol.frame = CGRectMake (0, 100, self.view.frame.size.width, 250); Scrol.delegate = self; Scrol.scrollEnabled = Yes; [Self.view addSubview: scrol]; Scrol.contentSize = CGSizeMake (221, 650); Scrol.backgroundColor = [UIColor blueColor]; A = [[UIView alloc] init]; Ephraff = CGRactam (10, 10, 221, 100); A.backgroundColor = [UIColor yellowColor]; [Scrollsviewview: A]; B = [[UIView alloc] init]; Beeframe = CGRactam (10, 120, 300, 100); B background color = [UIColor grayColor]; [Scrollsubject: b]; Firstimage1 = [[UIImageView alloc] init]; Firstimage1.frame = CGRectMake (5, 10, 180, 80); Firstimage1.backgroundColor = [UIColor redColor]; //firstimage1.image = [UIImage imageNamed: @ "Defult.png"]; [A aidview: firstmuse 1]; UITextField * Field 1 = [[UITextField alloc] init]; Field1.frame = CGRectMake (10, 10, 221, 30); Field1.backgroundColor = [UIColor whiteColor]; [B adsubview: field 1]; UITextField * field2 = [[UITextField alloc] init]; Field2.frame = CGRectMake (10, 50, 221, 30); Field2.backgroundColor = [UIColor whiteColor]; [B adsubview: field 2]; GetImages = [[UIButton alloc] init]; GetImages.frame = CGRectMake (0, 0, 28, 25); [Self.view addSubview: getImages]; [GetImages addTarget: Self-action: @Selector (AIMJS :) Control events: UIControlEventTouchDown]; [GetImages setbackground image: [UIImage imageNamed: @ "Defult.png"] forState: UIControlStateNormal]; Img1 = [[UIImagePickerController alloc] init]; Img1.delegate = self; Img1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; Img1.delegate = self; If (firstimage1.image) {firstimage1.hidden = NO; A.hidden = No; // If there is an image then just set A_View according to your requirement [one set frame: CGRactam (10, 10, 221, 100)]; According to the B_View and the Y coordinate + A_View height [B setframe: CGRactMake (0, A.

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...

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...
