autosize/resize UIPickerView for each screen sizes - ios

Question

I'm trying to adapte the size of my UIPickerView, and the content inside, I have resize the height of the picker view:
let pickerView = UIPickerView()
if DeviceType.IS_IPHONE_4_OR_LESS {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 100)
} else if DeviceType.IS_IPHONE_5 {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 200)
} else if DeviceType.IS_IPHONE_6 {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 200)
} else if DeviceType.IS_IPHONE_6P {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 250)
} else if UIDevice.currentDevice().userInterfaceIdiom == .Pad {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 300)
}
// pickerView.backgroundColor = .whiteColor()
pickerView.showsSelectionIndicator = true
pickerView.delegate = self
pickerView.dataSource = self
self.pickerView = pickerView
But now I want to resize the content inside, the height of each row, the size of the text, and do multiline if the content is too long, but I don't know how to do.
My code:
#IBOutlet var tfProjet: UITextField!
var pvProjetData = ["-Choisir-", "Rachat de crédits", "Renégociation de crédits"]
override func viewDidLoad() {
super.viewDidLoad()
let pickerView = UIPickerView()
if DeviceType.IS_IPHONE_4_OR_LESS {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 100)
} else if DeviceType.IS_IPHONE_5 {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 200)
} else if DeviceType.IS_IPHONE_6 {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 200)
} else if DeviceType.IS_IPHONE_6P {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 250)
} else if UIDevice.currentDevice().userInterfaceIdiom == .Pad {
pickerView.frame=CGRectMake(0, 200, view.frame.width, 300)
}
// pickerView.backgroundColor = .whiteColor()
pickerView.showsSelectionIndicator = true
pickerView.delegate = self
pickerView.dataSource = self
self.pickerView = pickerView
tfProjet.inputView = pickerView
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int{
return 1
}
func selectRow(row: Int, inComponent component: Int, animated: Bool){
}
func updatePicker(){
self.pickerView!.reloadAllComponents()
pickerView.selectRow(0, inComponent: 0, animated: false)
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
if tfProjet.isFirstResponder(){
return pvProjetData.count
}
return 1
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
if tfProjet.isFirstResponder(){
return pvProjetData[row]
}
return ""
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if tfProjet.isFirstResponder(){
let itemselected = pvProjetData[row]
tfProjet.text = itemselected
self.tfProjet.endEditing(true)
}
}

Forget doing that by code, use autolayout. Auytolayout is indepentent from device.
