How am I supposed to pass the variable from one stage to another?
I did it for the view, and I can't figure it out for the scene. ♪ ♪

In EndScene, declare an internal variable score

class EndScene: SKScene{
    var RestartB : UIButton!
    internal var score : NSInteger = 0

in the creation of EndScene transfer scores from GameScene

func collisionWithPerson(En: SKSpriteNode, Person: SKSpriteNode){
    En.removeFromParent()
    Person.removeFromParent()
let endScene = EndScene() //не путать endScene и EndScene
endScene.score = self.score
view?.presentScene(endScene)
Scorelbl.removeFromSuperview()

}

For the future, I'd like to read the singlton, I think you're gonna need a lot of data to run through the whole program. http://habrahabr.ru/post/198470/ Good article.

His problem is divided into two parts.1 - Optional values.It may be that this problem is not in its function add and yes in your class, where you are declaring your variables. Once you start a valueless variable it is necessary to pass the ? so she becomes Optional. that is, allowing her to stay nill.Example: class MyClass{ var a:String var b:String } If you declare this way in a playground you will notice the various error messages saying that the class itself is null and its attributes too, why none of your attributes are initialized.This will work:class MyClass{ var a:String? var b:String? } Let's say that in your log function you are sure that the Email field is worthwhile, you would put it ! for him "believe in your word that yes, this field has value," if you contract, you give fatal error and you can stop your app.Until then all right, just take a look at your class if the variables are being initialized and if not how to prevent this problem from happening.2 - Return of functionIf you are intending to make the getLogin function be void the signature type should be declared so: -> Void and not ->().

It varies a lot from how you have your implementation, I guess somewhere in your code you're using the locationManager.startUpdatingLocation() That makes you always call the didupdateLocations....My suggestion is to remove that, and update the user's location when you really need it using it locationManager.requestLocation(), this will send to call once the user's location request and launch your update with the current position. ...Locations # 1: [<+XX.XXXXX,-XXX.XXXXXXX> +/- 65.00m (speed -1.00 mps / course -1.00) @ 5/24/19, 11:38:09 AM Pacific Daylight Time]```

The simplest option is to check. HTTP_X_REQUESTED_WITHif(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') { //Пришел асинхронный запрос - выводим только обновляемую часть контента } else { //Выводим весь контент } It's true, with some building, the server might not fill. HTTP_X_REQUESTED_WITH♪ In this case, only the additional parameter remains to be used. $_GET or $_POST and look at him.

Theオプションdp and impdp commands do not explicitly indicate what is happening.Is the schemas option specified?Then, I think that it is or 11g or later because I use dp impdp.I think you can show the version position.Can I import only tables?Is the import destination schemas the same as the schemas on thesport side?I felt that I could not understand.Please refer to the following link: https://oracle-chokotto.com/ora_import_impdp.html https://docs.oracle.com/cd/E16338_01/server.112/b56303/dp_import.htm https://www.sql-dbtips.com/expdp-impdp/datapump-impdp/ http://alphafocus.cocolog-nifty.com/blog/2011/05/tips-oracleimpd.html

We need to tell the adapter that the data are up. It needs to be made available outside the method onCreate() and call notifyDataSetChanged() after the addition of the element:public class MainActivity extends AppCompatActivity { public List<String> list; private ArrayAdapter<String> adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); list = new ArrayList<>(); adapter = new ArrayAdapter<>(this, R.layout.array_adapter, list); ListView lv = findViewById(R.id.listView); lv.setAdapter(adapter); } @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult(requestCode, resultCode, data); String item = data.getStringExtra("main"); list.add(item); adapter.notifyDataSetChanged(); } public void floatinButton1OnClick(View view) { Intent intent = new Intent(this, AddElement.class); startActivityForResult(intent, 1); } }

The button itself has elements to be in different states, you can place the title with:button.setTitle("Yes", for: .normal) button.setTitle("No", for: .selected) Then you can place a background image equal to both states, as the button does not have a property for color we can create an image detached from a color as you can see below:public extension UIImage { public convenience init?(color: UIColor, size: CGSize = CGSize(width: 1, height: 1)) { let rect = CGRect(origin: .zero, size: size) UIGraphicsBeginImageContextWithOptions(rect.size, false, 0.0) color.setFill() UIRectFill(rect) let image = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() guard let cgImage = image?.cgImage else { return nil } self.init(cgImage: cgImage) } } And then with the selected color: let selectedColorImage = UIImage(color: UIColor.green) let unselectedColorImage = UIImage(color: UIColor.red) button.setBackgroundImage(selectedColorImage, forState: .normal) button.setBackgroundImage(unselectedColorImage, forState: .selected) you'd only have to put something that changes your state, as it can be in the IBAction of the button. @objc func buttonActionYesNo(sender: UIButton!) { sender.isSelected = !sender.isSelected }

This is a typical problem of the interface between different systems (not only python + node.js).Depending on the specificity of the task, input-outflows, socket-connections, shared memory, various IPC solutions and many other methods can be used for data transmission between subsystems.In general, where the subsystems are located on different machines (physical or virtual), the task can be accomplished through the use of the subsystems. Mediator for transmission from one subsystem to another. A good (although somewhat redundant) solution may be the number of communications: ActiveMQ, RabbitMQ, etc. You can try Redis with it. http://redis.io/topics/pubsub ♪In your particular case, you can try to use your client socket.io in the python app and send data on this channel. I think it'll be one of the simplest and most resource-neutral solutions.

Well, first of all, what you're doing in viewDidLoad doesn't really affect the work of the table, but as the comments say, it's a good decision to put resource-intensive actions in a separate flow. The FPS fall of the table depends on different factors: What's the code written in the cell ForRowAtIndexPath, whether you use auto-layouts or autoresizing-mask, if the first, is the right thing to break down, if the second, where and how you're breaking up the pieces, the CACE's data are in the boxes of the table, if it's the pictures, if you're doing it, you're doing it's so tight. There's not a bad article about how to achieve perfect tables: https://medium.com/ios-os-x-development/perfect-smooth-scrolling-in-uitableviews-fd609d5275a5#.ssbqdsgp3

Try to do this, being "dataframe" your data.import numpy as np import pandas as pd dataframe.fillna(np.nan, inplace=True) #rellenamos todos los valores que faltan con NaN dataframe.isna().sum() #Sumamos los NaN de cada columna EDITION 2Okay, seeing your update, I know what happens, what happens is that those cells are a string with spaces or nothing. To change it you have to do the following:#realizamos las operaciones para cambiar las celdas vacias o con espacios a nan dataframe = dataframe.replace('\s+', np.nan, regex=True).replace('', np.nan) #sumamos para saber los números de nan por columnas dataframe.isna().sum() What we do in the First replace is to replace all cells that have a space or more by, nan. And with him second We replace all cells that are empty strings per nan.

You can make a segue for the controller on your own and pass data on how many levels of investment are irrelevant. Subject: From the first controller on the Pass Data button, we transmit Dictionary with an arbitrary investment in DataViewControllerIn every application, the Next level goes to 1 level deeper.When we reach the last one, we go to DetailsViewController.Switch down to the UITableView cell and transmit the data.

I realized a syntax error in your code that may not be allowing you to find the correct id of what you want to edit:url: 'editafoto.php=id' + id, Where should I actually pass:url: 'editafoto.php?id=' + id, the "?" is to signal that from this point start your "Query String", and you say that there is a "parameter" called "id" whose value "=" is the content of the variable "id".But you also already have a HIDDEN-type field on the form as the "defoto" name that will pass that value, so you really need to mount that query string on the url of the page you're calling?Be very careful about security, as any user may change this "ID" and submit the form, then changing the data from another record, which may not be the appropriate one.It is also there to understand that if you are intending to upload a list of photos to open each one in a modal, so you will have to upload all the data from all the photos from the list on the screen to open one by one, that is, your html return might get huge. a more economical way would be to load the list and by clicking on a photo, upload the data to be edited through ajax.Maybe I didn't answer your question, but I'd rather relate here some alerts that could give you some guidance from where to follow.

I recommend a simple writing. REST Service Java or Python data access MongoDB♪ It's much easier than making direct connections. Swift and from an architectural point of view, much better.

In you Storyboard You've got a controller you've established customClass a MyTableCarViewController. However, this class does not exist in the repo. Hence the message: Unknown class MyTableCarViewController in Interface Builder file.By not finding the class, the Storyboard You must try to load with a UIViewController normal, and as you have set several outletsAnd one UIViewController normal does not contain any property ImageViewgive you that exception.Looks like you erased that class. accidentallyOr maybe you have. renamed.Either you assign to the Storyboard the right class, or create that class with the outlets you need

Try to set up the structure of the required json and call it "a." There was no need to transform it back, but I think that's how it works.let json = try! JSONSerialization.data(withJSONObject: a, options: .prettyPrinted) And then send URLRequest
