问题 i have a problem with CATransform3DTranslate. i concatenating it with CATransform3D with the code from KennyTM here i measured the coordinate using Photoshop. here is my complete code : background.image = UIImage(named: "backgroundtest") gambar.image = UIImage(named: "imagetest") gambar.layer.anchorPoint = CGPointZero var translate = CATransform3DIdentity translate = CATransform3DTranslate(translate, -160, -85.5, 0) var perspective = CATransform3DIdentity perspective = compute_transform

问题 Follwing another post: I would like to know if OCL allows the following. Imagine the following UML diagram. How to use ocl to model: "a person can drinkWater() only if he is from country name 'ABCD'" AND if the population of the country is >= 1000000" Of course, the example is purely fictive. ================ ================ | Person | | Country | |--------------| |--------------| |- name |------------------|- id | |- age | |- name | |--------------| |- population | |+ drinkWater()| ========

问题 If we start with this setup of HTML elements: ...and then we make use of CSS flexbox and apply the flex-grow property to the "body" element, we get this: Which is fantastic that it's behaviour that can be done purely in CSS without the need for any JavaScript. However, say we want to have a fixed height for the parent container element and that the child elements (i.e. header, body and footer), should not overflow the parent. Say the header and footer element content are fixed, but the body

问题 I am trying to set up fmincon with the active-set method for the linear constrained minimisation problem where minimising the objective function @fun such that but the trials firing odd errors more in the history. Trial 1 [x,fval]=fmincon(@fun, Guess, A, b) Trial 2 options = optimoptions('fmincon','Algorithm','active-set'); [x,fval]=fmincon(@fun, Guess, A, b, options) 回答1: You are using the wrong options for the algorithm. MATLAB looks at the parameters you provide and uses an algorithm that

问题 i got this in viewdidload rectShape1 = CAShapeLayer() rectShape1.fillColor = UIColor.blueColor().CGColor rectShape1.path = UIBezierPath(roundedRect: rectShape1.bounds, byRoundingCorners: .BottomLeft | .TopRight, cornerRadii: CGSize(width: 20, height: 20)).CGPath redview.layer.addSublayer(rectShape1) var constTop = NSLayoutConstraint(item: redview, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: view, attribute: NSLayoutAttribute.CenterX, multiplier: 1,

问题 I realize the title is crazy, but it really is the best I could think of. If anyone has better suggestions please leave them in the comments and I'll edit. This question is a followup to the question asked here : Drools Constraint object other than P is found in collection For those who don't want to click, that post describes the solution to the situation in which you want to know if there is a fact of CustomType which has a member field containing a value other than P. The Solution to this

问题 For some reason I am only getting the first few rows of data back from my query. I'm not sure what I am doing wrong. I need to get all the objects from one column named states row by row. But its only grabbing the first few rows. What am I doing wrong? ParseQuery<ParseObject> system = ParseQuery.getQuery("StatesSystem"); // system.fromLocalDatastore(); system.setLimit(30); system.orderByAscending("SpinnersTitle"); // system.whereExists("System"); system.findInBackground(new FindCallback

问题 This question is being asked/mentioned over and over but I could not find if I am doing something wrong or that the problem is "real": I have an entity class for a simple Oracle table in which there is one field that should be unique. It has a unique constraint in the DB. In the entity definition I added the JPA annotation - @Entity @Table(name = "tbl", uniqueConstraints = @UniqueConstraint(columnNames = "uni_field")) public class MyTable implements Serializable { ... @Column(name = "uni

问题 So I have a label that counts 1 every second using an NSTimer . I made an app that has a few moving UIImage s. However every time the timer counts one up, the view seemingly reloads and the UIImage s go back to their original positions. Furthermore, the UIImage s are not where I had placed them in the storyboard (I placed them outside the view so they could move inwards, but when I start the app it just shows them right there already. They move but only for one second then go back to their
