I would like to loop my numbers into the uitableviewcell and printing all the values from the highest number to the lowest and printing them in each cell. I posted the full code. See the cell.text output. This is my code:
import UIKit
class tableViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet var tableView: UITableView!
var arr = [Int]()
var cell:tableCell!
var Payment: float_t! = 59600
var years1: float_t! = //15 * 12 = 180
var monthlyPayment: float_t! = 471
var interest: float_t! = 5%
var principal: float_t! = 222
var interstate: float_t! = 249
var initil: float_t!
var data = Array<float_t>()
var data2: NSMutableArray = []
override func viewDidLoad() {
super.viewDidLoad()
let c = Int(years1)
arr += 0...c
tableCalculation()
let nib = UINib(nibName: "table", bundle: nil)
tableView.registerNib(nib, forCellReuseIdentifier: "cell")
}
func tableCalculation() {
let years = Int(years1)
initil = TPayment - 0
for i in 0..<years {
initil = initil - principil
interest = initil * interestrate
principil = monthlyPayment - interest
print("Month : \(monthlyPayment), principil: \(principil),interest: \(interest), initi: \(initil)")
self.data2 = [initil]
}
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arr.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
cell = self.tableView.dequeueReusableCellWithIdentifier("cell") as! tableCell
cell.lbl1.text = "\(arr[indexPath.row])"
cell.lbl2.text = currencyFormatter(monthlyPayment)
cell.lbl3.text = currencyFormatter(interest)
cell.lbl4.text = currencyFormatter(principil)
cell.lbl5.text = "\(self.data2[indexPath.row % data2.count])"
return cell
}
// 4
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("Row \(indexPath.row) selected")
}
// 5
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 70
}
func currencyFormatter(Price: float_t) ->String {
let currencyFormatter = NSNumberFormatter()
currencyFormatter.usesGroupingSeparator = true
currencyFormatter.numberStyle = NSNumberFormatterStyle.DecimalStyle
// localize to your grouping and decimal separator
let numberOfPlaces: float_t = 1.0
let multiplier: float_t = pow(10.0, numberOfPlaces)
let num = Price
let rounded = round(num * multiplier) / multiplier
let priceString = currencyFormatter.stringFromNumber(rounded)
return priceString!
}
}
This code always gives me the last number of the loop for all values, I would like to change it to write from the first value to the last one in every cell.

Answer 1

Welcome to SO. Neither your question nor your code make any sense.
It looks to me like you have no idea how to use table views.
You need to set up a data model (usually an array) that holds the data for your table view. Then when your cellForRowAtIndexPath method gets called, you look at the row (or row and section) in the request, fetch the data for that row (or row & section for a sectioned table view) and use that data to configure a cell which you return.

Answer 2

Try it this way:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
cell = self.tableView.dequeueReusableCellWithIdentifier("cell") as! tableCell
cell.lbl5.text = "\(initial - indexPath.row*225)" //subtracts each consecutive row by a higher multiple of 225.
return cell
}
You need to understand that cellForRow:atIndexPath is a UITableView datasource method that's called by the UIKit framework. It gets called when the tableview is loaded, based on the number of sections (specified by another datasource method), and the number of rows in each section (also specified by yet another datasource method).

Answer 3

Here's how table views work, like Duncan said you need to know.
/*We need to subclass UITableViewDataSource and UITableViewDelegate
so we gain access to tableView methods. Don't forget to link your
tableView in the storyboard to the delegate and datasource!*/
class controller: UIViewController, UITableViewDataSource, UITableViewDelegate {
//1: Model. All the data you're gonna use for your table view
var data = Array<String>()
override func viewDidLoad() {
//1: Populate model with some data when the view loads.
self.data = ["Oranges", "Apples", "Bananas", "Grapes"]
}
//2: Number of rows in table view. This determines how many times #3 is called (below).
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
//We want the table view to have all the items in variable `data`. So, we need to have as many cells as the number of items in `data`
return data.count
}
//3: This is called for each cell. It lets you customise each cell how you want.
//For us, we'll make the text inside the cell the current item in the `data` array
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//Get the cell from the tableView. Use the identifier you've specified in the storyboard.
let cell = tableView.dequeueReusableCellWithIdentifier("myCellIdentifier", forIndexPath: indexPath)
//Set the text as the current item in `data`
cell.textLabel?.text = data[indexPath.row]
//Use this cell we've just created for the current row
return cell
}
}
