Get data from Parse.com as Variable


The problem is that the Storyboard is creating a ViewController for you and then you are allocating a second one. Yours is not the one that is on screen, and since yours wasn't loaded from a Storyboard, your IBOutlet is nil.

Leave the Parse.setApplicationId("xxxx", clientKey: "xxxx") in AppDelegate.swift, but move the rest of your code to viewDidLoad in ViewController.swift. Then you'll be able to set your label because your IBOutlet won't be nil.

In your ViewController.swift file:

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var playerName: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        println("viewDidLoad")
        // Do any additional setup after loading
the view, typically from a nib.

        var gameScore = PFObject(className:
"GameScore")
        gameScore.setObject(1337, forKey: "score")
        gameScore.setObject("Sean Plott", forKey:
"playerName")
        gameScore.saveInBackgroundWithBlock {
            (success: Bool!, error: NSError!)
-> Void in
            if (success ?? false) {
                println("Object created with id:
(gameScore.objectId)")
            } else {
                println(error)
            }
        }

        var query = PFQuery(className:
"GameScore")

       
query.getObjectInBackgroundWithId("phNzKk6364") {

            (scoreAgain: PFObject!, error:
NSError!) -> Void in

            if error == nil {
                println("No Error: " +
(scoreAgain.objectForKey("playerName") as String))
                self.playerName.text =
scoreAgain.objectForKey("playerName") as String
            } else {
                println(error)
            }
        }
    }
}

How can I cache a csv for Papa Parse to parse?
The browser and server you're downloading the CSV file from should negotiate caching for you; I might misunderstand but I'm not sure what Papa Parse would have to do with that. For last modified date, if the file happens to be selected by the user with a <input type="file"> element on the page, you can access the File object and check its lastModified or lastModifiedDate properties (at leas

"Error 91: Object variable or With block variable not set" in code running perfectly last Friday
That is because rCategory is Nothing. The .Find is not returning anything. To test it, change your code to this. For iCategory = 1 To UBound(vCategories) Set rCategory = rPatterns.Find(What:=vCategories(iCategory)) If rCategory Is Nothing Then MsgBox vCategories(iCategory) & " Not Found" Else .Points(iCategory).Format.Fill.ForeColor.RGB = rCategory.Interior.Color

R: change data frame structure using values from one variable as new variable
To split the data: (s <- split(df1$score, df1$name)) # $a # [1] 1 # # $b # [1] 1 2 # # $c # [1] 1 To create the new data frame: as.data.frame(sapply(s, `length<-`, max(vapply(s, length, 1L)))) # a b c # 1 1 1 1 # 2 NA 2 NA Slightly more efficient would be to use vapply in place of sapply len <- max(vapply(s, length, 1L)) as.data.frame(vapply(s, `length<-`, double(len), len

When page is first loaded, it gets data for a variable, but after reload the variable is null
The problem is in your variable was that is checked when you redirect for xmlGetProductData. And after that you should set it to false or null like in initial state. if (!was) response.sendRedirect("xmlGetProductData"); request.getSession().setAttribute("was", false);
