Swifit (my first program) catching user input - swift

Question

I can't figure out how the value of a.sucess and a.attempt will come from the input of the user writing numbers in the success and attempt box.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var Attempts: UITextField!
#IBOutlet weak var Sucess: UITextField!
#IBOutlet weak var Check: UIButton!
#IBOutlet weak var thepage: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func Check(sender: UIButton) {
var str = "here"
class Tries {
var Attempts:Float64 = 100.00
var Sucess:Float64 = 50.00
init() {
}
func Shot() {
if Attempts < 99.5 {
print ("you need more attempts :( Shoot some more!!")
}
else if Attempts > 99 && Sucess > 49 && Sucess / Attempts > 0.4999
{
print("accepted")
} else {
print("failed ")
}
}
}
var a = Tries()
a.Attempts = 200 // this input should come from the user writing input in the textfield... (NEED HELP HERE)
a.Sucess = 100 // this input should come from the user writing input in the textfield... (NEED HELP HERE)
a.Shot() // This is the function that should load when you click on the button: click
}
I want a.Attempts and a.Sucess to get the value from the user writing his/Her own numbers in the two boxes.

Answer 1

First of all you have a very bad style of writing code. What you wrote is very difficult to read. Call variables clearer and do not call objects with a capital letter, it need call the names indicate the type and not the names of the objects. Reed this for example: https://github.com/raywenderlich/swift-style-guide to make your code more clear.
About you problem. Maybe I did not quite understand the question, but apparently you just have to read the value of the UITextField object and you can do it like:
let strValue = textField.text // in your case Attempts.text
then you need to convert it to CGFloat:
let floatValue = CGFloat((strValue as NSString).floatValue)
and then you can use it in your object:
a.Attempts = floatValue
You should still check that the conversion went well and only then assign a value.
You can do this for example to solve you problem:
import UIKit
class ValuesChecker {
class func checkValues(firstValue: Float, secondValue: Float) -> String {
if firstValue < 99.5 {
return "you need more attempts :( Shoot some more!!"
} else if firstValue > 99 && secondValue > 49 && secondValue / firstValue > 0.4999 {
return "accepted"
} else {
return "failed "
}
}
}
class ViewController: UIViewController {
#IBOutlet weak var firstTextField: UITextField!
#IBOutlet weak var secondTextField: UITextField!
#IBAction func actionWithPressButton(sender: AnyObject) {
let firstValue = (firstTextField.text as NSString).floatValue
let secondValue = (secondTextField.text as NSString).floatValue
println(ValuesChecker.checkValues(firstValue, secondValue: secondValue))
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
Comments:
You dont need to create class object in your case. You can create static class method like checkValues
Instead of a String you can give out test results in any way, and use it later in the program
