Goyo's questions

I'm trying to make a table with custom cells in swift so far it's going well, but I decided to add a button me gustato each cell, the button when pressed simply changes its image, so the problem I have is that: Every time I press the button me gustayes it changes the image of the button but it changes it for the cell in which the button is pressed and for others in the same list as shown in the following image:

What happens in the image is that I press the top button but the bottom button also changes (for example), I am trying to reuse the same cell with dequeueReusableCellWithIdentifierthis is my code:

extension ViewController : UITableViewDataSource {

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 8
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = self.tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! DestinoTableViewCell
        cell.btnCorazon.tag = indexPath.row
        cell.btnCorazon.addTarget(self, action: #selector(changueButon), forControlEvents: .TouchUpInside)
        return cell
    }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
       print("select", indexPath.row)
    }

    func changueButon(sender: UIButton){

        if(!self.isLove){
            if let image = UIImage(named: "heart.png") {
                sender.setImage(image, forState: .Normal)

                isLove = true
            }
        }else{
            if let image = UIImage(named: "fav.png") {
                sender.setImage(image, forState: .Normal)
                isLove = false
            }
        }

    }
}

So my question is: Is there a way to fix this problem? And if there is, what is it?

I'm trying to round a decimal number, but what normally happens is that if the number is assuming 40.40it stays in 40, and if it is it 40.60goes up, 41my code is as follows:

decimal price = 13224.60m;
int aux = (int) Math.Round(Convert.ToDouble(price), 0, MidpointRounding.ToEven);

like this the code if I execute it gives me the result 13225, but if I change the value of pricea 13224.40:

decimal price = 13224.40m;
int aux = (int) Math.Round(Convert.ToDouble(price), 0, MidpointRounding.ToEven);

gives me the result 13224, and what I want is that I always round it up, that is, that in any of the two cases I round it to 13225.

is there any way to do that ? And if there is, how would the implementation be?

I want to make a table like the one in the image, but the problem is that I want to do it with a dynamic table, since each section, for example the Adult section, can vary the number of cells depending on the passengers, just as the Children section can vary also, that's why I don't do it with a static type table, so the question is:

Is there a way to make a layout like the one in the picture using a pivot table? Or do I have to use a static table? But if I use a static table, how can I add the cells of each section to it dynamically?

Hi, I'm trying to do my login with the apifacebook one, but when I send the request it seems to be a problem with the urlones I added so that the callback, I'm working with sails.jsusing the framework of passport, the error that marks me is the following:

If anyone has an idea how to fix it I would appreciate it.

I am trying to create a two-position vector, where at each position I add a two-dimensional array of type string, which leads me to create a two-dimensional array list as follows:

List<String[,]> multi = new List<string[,]>();

then create my two dimensional array and add the values ​​to it as follows just as an example:

string[,] m2 = new string[2, 2];

m2[0, 0] = "jose";
m2[0, 1] = "juan";
m2[1, 0] = "luis";
m2[1, 1] = "pedro";

then add that array to the list as follows:

multi.Add(m2);

The problem here is that when I want to pass my list to a arraywith the toArray()following method, I get an error:

string[] main = multi.ToArray();

The question is: How can I make that list become a array?

I would like to know if anyone knows the difference between these two ways of declaring multidimensional arrays in c#.

string[][] m = new string[2][]; // primera forma

string[,] m2 = new string[2, 2]; // segunda forma

And because when I declare it as follows:

string[][] m = new string[2][2]; // <- me marca un error

It gives me an error when assigning the second length between the second pair of square brackets.

As a note I want to mention that I always declare them in the second way mentioned in the first code block.

Normally I do iterations using the control statement forand thus I get the index of the iteration easily, but the question I have is the following, Is there a way to get the index of the iteration in an foreachen c#?

since I usually get it out like this:

int i=0;
foreach (var item in array)
{

   i++;
}

The other question would be, if there is a way to get the index in a different way than the example, what is it?

I am making asynchronous requests and I am storing them in a list Task, at the end of the iteration, that is, since it sends all the requests, I use the method WhenAll().Resultto capture all the responses once the requests have finished and save them in an array, as shown in the following code:

try
{
   IEnumerable<Task<string>> task = requestArray.Select((a, i) =>
   {
       var fareIds = new List<string>();
       var ticketsId = new List<string>();
       var seatsNumber = new List<string>();

       for (var posSeat = 0; posSeat < requestArray[i].seats.Length; posSeat++)
       {
           fareIds.Add(requestArray[i].seats[posSeat].fareId.ToString());
           ticketsId.Add(requestArray[i].seats[posSeat].ticketId.ToString());
           seatsNumber.Add(requestArray[i].seats[posSeat].number.ToString());
        }

        var xml = BlockSeatRQ(i, seatsNumber.ToArray(), fareIds.ToArray(), ticketsId.ToArray(), tokenRQ);

        WebClient client = new WebClient();
        client.Headers.Add("Content-Type", "application/xml");

        return Task.Run(() => client.UploadStringTaskAsync(Config.Endpoint + SEAT_BLOCK_URL, "POST", xml));
   });

   blockSeatResponses = Task.WhenAll(task).Result;       
}
catch (WebException e)
{


}

The problem I have is that when an exception arises, it does not enter the catch, but rather it thunders when the method WhenAllis called, as shown in the following image:

Now the question is, why doesn't it enter the catch? And how can I make it enter the catch? Since the service I am using does not return a specific error to use, it simply allows me to enter Exceptionand get the error message.WebExceptionBody

I hope you understand the problem.

I am doing a concatenation c#where I want the result to be equal to the following:

variable = "null,null"

But I am doing this concatenation in a forand it looks more or less like this:

string variable = "";

for (int pos= 0; pos < asientos.Length; pos++)
{
    if (pos == asientos.Length - 1)
        variable += "null";
    else
        variable += "null" + ",";
}

The ifone that I place in the iteration is so that the ,(comma) is not added at the end, now the question or rather doubt is, is there a better way to do that validation in that concatenation?, and if there is, what is it? ?

Well the question here is that I'm working on a razor file and I want to create a json from an array in vb.netthe following way:

For Each ItineraryPnr In ItinerariesNode.ChildNodes
    arrayPnrRetrieve(contPnr) = New With {Key .trasactionId = ItineraryPnr.SelectSingleNode("TransactionId").InnerText, .isSucces = False, .provider = ItineraryPnr.SelectSingleNode("Provider").InnerText, .pnr = ItineraryPnr.SelectSingleNode("PNR").InnerText, .errors = Nothing}
    contPnr = contPnr + 1
Next

Dim serializerPnrModel As New JavaScriptSerializer()
Dim jsonPnrRQ As String = serializerPnrModel.Serialize(arrayPnrRetrieve)

The above generates something like the following and I assign it to the variable jsonPnrRQ:

[
  {
   "trasactionId":"c592360b-3d29-4689-9683-8b53b4880099",
   "isSucces":false,
   "provider":"4O",
   "pnr":"DBZD2N",
   "errors":null
  }
]

So when wanting to assign it to a variable javascriptin the following way:

 @<script>
     var metadata = {};            

     metadata.jsonEx = {};
     metadata.jsonEx.pnrRetrieve = @jsonPnrRQ;
     metadata.jsonEx.sequenceNumber = "3";

  </script>

It leaves the page cycled and sends me a syntax error, since the variable jsonPnrRQwhen debugging it is in a correct format.

The error is the following:

Uncaught SyntaxError: Unexpected token &

The question would be if anyone has happened and has a solution for this?

When printing my object Jsit shows it to me as follows

 metadata.jsonEx = {};
 metadata.jsonEx.pnrRetrieve = [{"trasactionId":"c592360b-3d29-4689-9683-8b53b4880099","isSucces":false,"provider":"4O","pnr":"DBZD2N","errors":null}];
 metadata.jsonEx.sequenceNumber = "3";

And I think that may be the problem, so the other question would be, does anyone have an idea why it is assigned to me like this and how I can solve it? being that the variable jsonPnrRQhas its value well (this is because when debugging it it comes out with the correct format).

How can I validate a postal code, that is, if there is an exact length or something that validates that it is actually a postal code, this either through a regular expression or in another way, but using JavaScript.

How do I get the URLcurrent one on the website? using javascript.

What I want is to know if I can get the urlone from a website, but for example if I am in the section I /conocenoswant to get http://sitioWeb/conocenos.

I want to know if there is any way to convert a xmlto jsonusing Javascript.

assuming i have the followingjson

seats = [
  {
    rows:[
      {
        "seatNUmber": "A",
        "IsAvailable": true
      },
      {
        "seatNUmber": "B",
        "IsAvailable": true
      },
      {
        "seatNUmber": "C",
        "IsAvailable": false
      },
      {
        "seatNUmber": "D",
        "IsAvailable": true
      }
    ]
  },
  {
    rows:[
      {
        "seatNUmber": "A",
        "IsAvailable": true
      },
      {
        "seatNUmber": "B",
        "IsAvailable": true
      },
      {
        "seatNUmber": "C",
        "IsAvailable": false
      },
      {
        "seatNUmber": "D",
        "IsAvailable": true
      }
    ]
  }

I would like to know how can I parse this jsonin a list <ul>? That is, that each seatNumber is in one <li>of the list. I guess it's a nested Loop but I can't understand how to put the ng-repeat.

The result I want to achieve is something like the following:

Where each box represents an entry and is one <li>of the list.

Assuming I have the following object:

var results = {
   itinerary:"01",
   seats:[
      {
        rows:[
          {
            "seatNUmber": "A",
            "IsAvailable": true
          },
          {
            "seatNUmber": "B",
            "IsAvailable": true
          },
          {
            "seatNUmber": "C",
            "IsAvailable": false
          },
          {
            "seatNUmber": "D",
            "IsAvailable": true
          }
        ]
      },
      {
        rows:[
          {
            "seatNUmber": "A",
            "IsAvailable": true
          },
          {
            "seatNUmber": "B",
            "IsAvailable": true
          },
          {
            "seatNUmber": "C",
            "IsAvailable": false
          },
          {
            "seatNUmber": "D",
            "IsAvailable": true
          }
        ]
      }
   ]
}

So what I want to know is how can I parse this object into a table or a list, but dynamically create the components with jQuery?

Something like when parsing with AngularJS using ng-repeatbut in this case using jQuery.

Assuming I have the following array of objects:

    var travelers = [
         {
           "name":"ana",
           "lastname":"gomez"
         },
         {
           "name":"juan",
           "lastname":"gomez"
         },
         {
           "name":"luis",
           "lastname":"gomez"
         },
         {
           "name":"pedro",
           "lastname":"gomez"
         }
    ];

I would like to know if there is a way to remove an object from the array in pure JavaScript or jQuery , by entering the position of the object to be removed.

What is the difference between?:

$(function(){

});

Y

$(document).ready(function() { 

});

I know they wait for the components to load, but would like to know why they are written differently?
