In Parse, to make a new user, I used:
var user = PFUser()
user.username = "myUsername"
user.password = "myPassword"
user.email = "[email protected]"
What's the code used in CloudKit to create a new user and use it for login?
I had to do something similar recently. I had to create a CKRecord for each user that contained the user's username and password. I added their username to NSUserDefaults to make it easy to retrieve.
Here is the code for signing up:
//Check if users exist
let query = CKQuery(recordType: "MyUsers", predicate: NSPredicate(format: "TRUEPREDICATE", argumentArray: nil))
pubDB.performQuery(query, inZoneWithID: nil, completionHandler: { (records, error) in
//error code 11 is no objects found
if error == nil || error?.code == 11 {
var usernameExists = false
for record in records! {
if record.objectForKey("username") as? String == self.usernameField.text {
//other user with the same username exists - don't allow user to create account
usernameExists = true
}
}
if usernameExists == true {
//displayErrorAlert is a function in which I display an error alert to the user
displayErrorAlert("Username \(self.usernameField.text!) is taken. Please choose another one.", vc: self)
} else {
//user can sign up
let record = CKRecord(recordType: "MyUsers")
record.setObject(self.usernameField.text!, forKey: "username")
record.setObject(self.passwordField.text!, forKey: "password")
pubDB.saveRecord(record, completionHandler: { (record, error) in
if error == nil {
NSOperationQueue.mainQueue().addOperationWithBlock {
NSUserDefaults.standardUserDefaults().setObject(self.usernameField.text!, forKey: "username")
username = self.usernameField.text!
self.performSegueWithIdentifier("account", sender: self)
}
} else {
print(error)
}
})
}
} else {
print(error)
}
})
Here is the code for logging in:
//query users to find current user
let query = CKQuery(recordType: "MyUsers", predicate: NSPredicate(format: "TRUEPREDICATE", argumentArray: nil))
pubDB.performQuery(query, inZoneWithID: nil, completionHandler: { (records, error) in
//we do not need to check for error code 11 because a user should exist
if error == nil {
var userExists = false
for record in records! {
if record.objectForKey("username") as? String == self.usernameField.text {
if record.objectForKey("password") as? String == self.passwordField.text {
NSOperationQueue.mainQueue().addOperationWithBlock {
userExists = true
NSUserDefaults.standardUserDefaults().setObject(self.usernameField.text!, forKey: "username")
username = self.usernameField.text!
self.performSegueWithIdentifier("account", sender: self)
}
} else {
//user with the username exists, but the password does not match
displayErrorAlert("Your password is incorrect", vc: self)
}
}
}
if userExists == false {
//user with that username does not exist
displayErrorAlert("Your username is incorrect", vc: self)
}
} else {
print(error)
}
})
}
When the view appears, I call this code to check for a current user:
if NSUserDefaults.standardUserDefaults().objectForKey("username") != nil {
username = NSUserDefaults.standardUserDefaults().objectForKey("username") as! String
self.performSegueWithIdentifier("account", sender: self)
}
The variable username is a global variable for all classes. If you do not prefer to user global variables, you should change it.
Hope this helps.
