如果@IBOutlet weak var mySwitch: UISwitch!
@IBOutlet weak var myTextField: UITextField!
@IBOutlet weak var User: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
// sets the textfield to the intended conversion on load.
if mySwitch.on {
myTextField.text = "Convert to Celius"
}
else {
myTextField.text = "Convert to Farheniet"
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// changes the myTextFiled text to the intended conversion when the switch is manually switched on or off
@IBAction func switched(sender: AnyObject) {
if mySwitch.on {
myTextField.text = "Convert to Celsius"
}
else {
myTextField.text = "Convert to Fahrenheit"
}
}
// changes the myTextField text to intended reverse conversion after the buttonClicked func is completed.
func stateChanged(switchState: UISwitch) {
if switchState.on {
myTextField.text = "Convert to Celsius"
}
else {
myTextField.text = "Convert to Fahrenheit"
}
}
// do the intended conversion(old version of XCode 6.4)
@IBAction func buttonClicked(sender: AnyObject) {
if mySwitch.on {
var a = (User.text! as NSString).doubleValue
a = (a-32)*(5/9)
User.text="\(a)"
mySwitch.setOn(false, animated:true)
stateChanged(mySwitch)
}
else {
var a = (User.text! as NSString).doubleValue
a = a * (9/5) + 32
User.text="\(a)"
mySwitch.setOn(true, animated:true)
stateChanged(mySwitch)
}
}
