N.B: This is not a repeat question, I have looked at the other solutions but none are working in Swift 3, but they do in Swift 2.
I need to get an image from a photo library with UIImagePickerController, that is working fine, then what I need to do, is to somehow save that to a public record in CloudKit, I am very open as to how this is done. Please, if possible, be clear as to what I need to change/add and where.
I have provided my entire view controller file just to be sure.
import UIKit
import CloudKit
var email: String = ""
class ViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
//MARK: Properties
@IBOutlet weak var firstNameField: UITextField!
@IBOutlet weak var lastNameField: UITextField!
@IBOutlet weak var emailField: UITextField!
@IBOutlet weak var passwordField: UITextField!
@IBOutlet weak var confirmPasswordField: UITextField!
@IBOutlet weak var notMatching: UILabel!
@IBOutlet weak var emailLabel: UILabel!
@IBOutlet weak var errorLabel: UILabel!
@IBOutlet weak var photoImageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.firstNameField.autocorrectionType = .no
self.lastNameField.autocorrectionType = .no
self.emailField.autocorrectionType = .no
self.passwordField.autocorrectionType = .no
self.confirmPasswordField.autocorrectionType = .no
self.notMatching.isHidden = true
firstNameField.delegate = self
lastNameField.delegate = self
emailField.delegate = self
passwordField.delegate = self
confirmPasswordField.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//MARK: UIImagePickerControllerDelegate
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
// Dismiss the picker if the user canceled.
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
// The info dictionary may contain multiple representations of the image. You want to use the original.
guard let selectedImage = info[UIImagePickerControllerOriginalImage] as? UIImage else {
fatalError("Expected a dictionary containing an image, but was provided the following: \(info)")
}
// Set photoImageView to display the selected image.
photoImageView.image = selectedImage
// Dismiss the picker.
dismiss(animated: true, completion: nil)
}
//MARK: Actions
@IBAction func selectImageFromPhotoLibrary(_ sender: UITapGestureRecognizer) {
//Hide keyboards
firstNameField.resignFirstResponder()
lastNameField.resignFirstResponder()
emailField.resignFirstResponder()
passwordField.resignFirstResponder()
confirmPasswordField.resignFirstResponder()
let imagePickerController = UIImagePickerController()
imagePickerController.sourceType = .photoLibrary
imagePickerController.delegate = self
present(imagePickerController, animated: true, completion: nil)
}
@IBAction func signUpPressed(_ sender: UIButton) {
let container = CKContainer.default()
let pubDB = container.publicCloudDatabase
//let privDB = container.privateCloudDatabase
//Check if users exist
let query = CKQuery(recordType: "MyUsers", predicate: NSPredicate(format: "TRUEPREDICATE", argumentArray: nil))
pubDB.perform(query, inZoneWith: nil, completionHandler: { (records, error) in
//error code 11 is no objects found
if error == nil || error?._code == 11 {
var emailExists = false
for record in records! {
if record.object(forKey: "email") as? String == self.emailField.text {
//other user with the same username exists - don't allow user to create account
emailExists = true
}
}
if emailExists == true {
self.emailLabel.text = "\(self.emailField.text!) is taken. Please choose another one."
} else {
if self.firstNameField.text != nil && self.lastNameField.text != nil && self.passwordField.text == self.confirmPasswordField.text {
//user can sign up
let record = CKRecord(recordType: "MyUsers")
record.setObject(self.emailField.text! as CKRecordValue?, forKey: "email")
record.setObject(self.passwordField.text! as CKRecordValue?, forKey: "password")
record.setObject(self.firstNameField.text! as CKRecordValue?, forKey: "firstName")
record.setObject(self.lastNameField.text! as CKRecordValue?, forKey: "lastName")
print("all good")
pubDB.save(record, completionHandler: { (record, error) in

OperationQueue.main.addOperation {

//self.performSegue(withIdentifier: "Games", sender: self)
}
} else {
print(error)

} else {
print(error)

}
// MARK: UITextFieldDelegate
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
// Hide the keyboard.
textField.resignFirstResponder()
return true
}
}
Thank you!
