Retrieving a specific value from an array to the custom cell - Swift - ios

Question

I'm playing around with custom cells.
With the great help from the stackoverflow community i've been able to put some code together. I'm able to fetch array values from a text string into a custom cell uilabel and uibutton, but the issue is - the fetched result is always the last object in the array.
Here is the code
func setUpQuestion()
{
// setting variables
var Question: String?
var option1: String?
// using a text string with custom separators
let text = ">>Here is the grocery question\n>>and another one\n--Apples\n-
-Oranges\n[pickApples]pickOranges\n[pickApples2]"
// splitting this string into four different arrays depending on the separator
let lines = split(text) { $0 == "\n" }
for line in lines {
if line.hasPrefix(">>") {
Question = line.substringFromIndex(advance(line.startIndex, 2))
} else if line.hasPrefix("[") {
if let index = line.rangeOfString("]")?.startIndex {
option1 = line.substringWithRange(Range<String.Index>(
start: advance(line.startIndex, 1), end: index))
}
}
}
// creating variables for appending the values - here I'm using a custom class called QuestionMark created in a separate .swift file
var question1 = QuestionMark(Question: Question!, option:option1!)
var question2 = QuestionMark(Question: Question!, option:option1!)
// appending the values into uilabel and uibutton in the custom cell
arrayOfQuestions.append(question1)
arrayOfQuestions.append(question2)
}
// regular tableView protocol functions
func tableView(tableView: UITableView, numberOfRowsInSection
section: Int) ->Int
{
return arrayOfQuestions.count
}
func updateCount(){
if let list = mainTableView.indexPathsForSelectedRows() as? [NSIndexPath] {
rowsCount.text = String(list.count)
}
}
func tableView(tableView: UITableView, cellForRowAtIndexPath
indexPath: NSIndexPath) -> UITableViewCell
{
let cell: CustomCellForTableViewTableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell") as! CustomCellForTableViewTableViewCell
// the SetCell function i'm using here was created in a separate .swift file
let quest = arrayOfQuestions[indexPath.row]
cell.setCell(quest.Questme!, optionone: quest.optionize!)
cell.optionOne.backgroundColor = UIColor.redColor()
return cell
}
Here are the additional codes i'm using for the class and setCell function
class QuestionMark
{
var Questme: String?
var optionize: String?
init(Question: String, option: String)
{
self.Questme = Question
self.optionize = option
}
// separate swift file
func setCell(Question: String, optionone: String)
{
self.mainText.text = Question
self.optionOne.setTitle(optionone, forState:UIControlState.Normal)
}
As a result in both cells i'm getting the last object from the text string and it looks like this
And another one - PickApples2
And another one - PickApples2
How do i start appending cells from the first array value and then move forward to second,third,fourth ?
Any ideas are greatly appreciated.
Thank you.

First of all, the syntax of the text to parse is pretty complicated ;-) …
Second of all, the problem to get always the last object is that you create the array of questions after the repeat loop. At that moment the variables question and option contain always the last found string.
Here a solution:
After getting a question a new object QuestionMark is created and appended to the array (without the optionize property)
After getting an option the appropriate QuestionMark object is fetched from the array by an index counter, the property optionize is set and the counter is increased.
Two notes:
Variable names should always start with a lowercase letter. Even the syntax highlighter of StackOverflow follows that naming convention.
In my solution all variables are non-optionals.
class QuestionMark
{
var questme: String
var optionize: String
init(question: String, option: String = "")
{
self.questme = question
self.optionize = option
}
...
var arrayOfQuestions = [QuestionMark]()
func setupQuestion() {
let text = ">>Here is the grocery question\n>>and another one\n--Apples\n--Oranges\n[pickApples]pickOranges\n[pickApples2]"
// splitting this string into four different arrays depending on the separator
var counter = 0
var question = ""
var option = ""
let lines = split(text) { $0 == "\n" }
for line in lines {
if line.hasPrefix(">>") {
question = line.substringFromIndex(advance(line.startIndex, 2))
let questionMark = QuestionMark(question: question)
arrayOfQuestions.append(questionMark)
} else if line.hasPrefix("[") {
if let index = line.rangeOfString("]")?.startIndex {
option = line.substringWithRange(Range<String.Index>(
start: advance(line.startIndex, 1), end: index))
let questionMark = arrayOfQuestions[counter]
questionMark.optionize = option
counter++
}
}
}
}
