DatePicker config quickly
Sorry for my english and question!
I am using xCode 6 with swift
I'm trying to develop my own application and I don't know how to ask the user to set a date, so I can use that value on the other side: S, I don't care if it uses a DatePicker with scrolling or some other way, it just needs the user to be able to set any date. I cannot guess how datePicker: S works
I found this code inside the course that develops "Tinder", when it asks for your date of birth in the login, I adapt it for my application, but it doesn't work and I don't know why: S
import UIKit
class SignUpController: UIViewController, UITextFieldDelegate {
var pickerContainer = UIView()
var picker = UIDatePicker()
@IBOutlet weak var selectedDate: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
self.selectedDate.setTitle("", forState: UIControlState.Normal)
configurePicker()
}
func configurePicker()
{
pickerContainer.frame = CGRectMake(0.0, 600.0, 320.0, 300.0)
pickerContainer.backgroundColor = UIColor.whiteColor()
picker.frame = CGRectMake(0.0, 20.0, 320.0, 300.0)
picker.setDate(NSDate(), animated: true)
picker.maximumDate = NSDate()
picker.datePickerMode = UIDatePickerMode.Date
pickerContainer.addSubview(picker)
var doneButton = UIButton()
doneButton.setTitle("Done", forState: UIControlState.Normal)
doneButton.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)
doneButton.addTarget(self, action: Selector("dismissPicker"), forControlEvents: UIControlEvents.TouchUpInside)
doneButton.frame = CGRectMake(250.0, 5.0, 70.0, 37.0)
pickerContainer.addSubview(doneButton)
self.view.addSubview(pickerContainer)
}
@IBAction func selectDate(sender: AnyObject)
{
UIView.animateWithDuration(0.4, animations: {
var frame:CGRect = self.pickerContainer.frame
frame.origin.y = self.view.frame.size.height - 300.0 + 84
self.pickerContainer.frame = frame
})
}
func dismissPicker ()
{
UIView.animateWithDuration(0.4, animations: {
self.pickerContainer.frame = CGRectMake(0.0, 600.0, 320.0, 300.0)
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
self.selectedDate.setTitle(dateFormatter.stringFromDate(self.picker.date), forState: UIControlState.Normal)
})

I have made some changes for you. In addition to adding one right parenthesis at the end of the code, I have changed the CGRectMake coordinates in two places. Everything was on the screen. When I implemented the code, I added a button to display the date in the upper left corner of the view and linked it to the IBOutlet. This should get you off to a good start.
import UIKit
class SignUpController: UIViewController, UITextFieldDelegate {
var pickerContainer = UIView()
var picker = UIDatePicker()
@IBOutlet weak var selectedDate: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
self.selectedDate.setTitle("", forState: UIControlState.Normal)
configurePicker()
}
func configurePicker()
{
pickerContainer.frame = CGRectMake(0.0, 50, 320.0, 300.0)
pickerContainer.backgroundColor = UIColor.whiteColor()
picker.frame = CGRectMake(0.0, 20.0, 320.0, 300.0)
picker.setDate(NSDate(), animated: true)
picker.maximumDate = NSDate()
picker.datePickerMode = UIDatePickerMode.Date
pickerContainer.addSubview(picker)
var doneButton = UIButton()
doneButton.setTitle("Done", forState: UIControlState.Normal)
doneButton.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)
doneButton.addTarget(self, action: Selector("dismissPicker"), forControlEvents: UIControlEvents.TouchUpInside)
doneButton.frame = CGRectMake(250.0, 5.0, 70.0, 37.0)
pickerContainer.addSubview(doneButton)
self.view.addSubview(pickerContainer)
}
@IBAction func selectDate(sender: AnyObject)
{
UIView.animateWithDuration(0.4, animations: {
var frame:CGRect = self.pickerContainer.frame
frame.origin.y = self.view.frame.size.height - 300.0 + 84
self.pickerContainer.frame = frame
})
}
func dismissPicker ()
{
UIView.animateWithDuration(0.4, animations: {
self.pickerContainer.frame = CGRectMake(0.0, 50, 320.0, 300.0)
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
self.selectedDate.setTitle(dateFormatter.stringFromDate(self.picker.date), forState: UIControlState.Normal)
})
}
