I'm using the following to send text to wit.ai through a button press function:
#IBAction func searchButton(sender: AnyObject) {
searchQueryText = searchTextInput.text!
if searchQueryText != "" {
wit.interpretString(searchQueryText, customData: nil)
}
func interpretString(string: String, customData: AnyObject) {
}
this works fine as the text is sent to wit.ai. However I get no response from wit.ai back to the app. I can get the response fine if a microphone is used, just not text. I have tried calling the witDidGraspIntent function to force it to run on button press, but I can't work out what I should use in the 'outcomes' parameter. Can anybody help on this? I'm not sure if there is a different way to run the function after button press? This is the function:
func witDidGraspIntent(outcomes: [AnyObject]!, messageId: String!, customData: AnyObject!, error e: NSError!) {
if ((e) != nil) {
print("\(e.localizedDescription)")
return
}
let outcomes : NSArray = outcomes!
let firstOutcome : NSDictionary = outcomes.objectAtIndex(0) as! NSDictionary
if let intent = firstOutcome.objectForKey("intent") as? String {
searchResultsIntent = intent
}
if searchResultsIntent == "searchIntent" {
intentLabel.text = "\(searchResultsIntent)"
print(outcomes[0])
} else {
intentLabel.text = "I'm sorry, I did not understand that."
}
}
here is the documentation for wit.ai: https://wit.ai/docs/ios/4.0.0/api
any assistance is greatly appreciated!
cheers.
Wit sdk gives a sharedInstance (singleton) for users to work on, so you have initiate it like -:
Wit.sharedInstance().accessToken = "TOKEN"
Wit.sharedInstance().delegate = self
and invoke the interpretString function using the sharedInstance i.e.
Wit.sharedInstance().interpretString(text, customData: nil)

I'm trying to share a record with other users in CloudKit but I keep getting an error. When I tap one of the items/records on the table I'm presented with the UICloudSharingController and I can see the iMessage app icon, but when I tap on it I get an error and the UICloudSharingController disappears, the funny thing is that even after the error I can still continue using the app.
Here is what I have.
Code
var items = [CKRecord]()
var itemName: String?
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let item = items[indexPath.row]
let share = CKShare(rootRecord: item)
if let itemName = item.object(forKey: "name") as? String {
self.itemName = item.object(forKey: "name") as? String
share[CKShareTitleKey] = "Sharing \(itemName)" as CKRecordValue?
} else {
share[CKShareTitleKey] = "" as CKRecordValue?
self.itemName = "item"
}
share[CKShareTypeKey] = "bundle.Identifier.Here" as CKRecordValue
prepareToShare(share: share, record: item)
}
private func prepareToShare(share: CKShare, record: CKRecord){
let sharingViewController = UICloudSharingController(preparationHandler: {(UICloudSharingController, handler: #escaping (CKShare?, CKContainer?, Error?) -> Void) in
let modRecordsList = CKModifyRecordsOperation(recordsToSave: [record, share], recordIDsToDelete: nil)
modRecordsList.modifyRecordsCompletionBlock = {
(record, recordID, error) in
handler(share, CKContainer.default(), error)
}
CKContainer.default().privateCloudDatabase.add(modRecordsList)
})
sharingViewController.delegate = self
sharingViewController.availablePermissions = [.allowPrivate]
self.navigationController?.present(sharingViewController, animated:true, completion:nil)
}
// Delegate Methods:
func cloudSharingControllerDidSaveShare(_ csc: UICloudSharingController) {
print("saved successfully")
}
func cloudSharingController(_ csc: UICloudSharingController, failedToSaveShareWithError error: Error) {
print("failed to save: \(error.localizedDescription)")// the error is generated in this method
}
func itemThumbnailData(for csc: UICloudSharingController) -> Data? {
return nil //You can set a hero image in your share sheet. Nil uses the default.
}
func itemTitle(for csc: UICloudSharingController) -> String? {
return self.itemName
}
ERROR
Failed to modify some records
Here is what I see...
Any idea what could be wrong?
EDIT:
By the way, the error is generated in the cloudSharingController failedToSaveShareWithError method.
Looks like you're trying to share in the default zone which isn't allowed. From the docs here
Sharing is only supported in zones with the
CKRecordZoneCapabilitySharing capability. The default zone does not
support sharing.
So you should set up a custom zone in your private database, and save your share and records there.
Possibly it is from the way you're trying to instantiate the UICloudSharingController? I cribbed my directly from the docs and it works:
let cloudSharingController = UICloudSharingController { [weak self] (controller, completion: #escaping (CKShare?, CKContainer?, Error?) -> Void) in
guard let `self` = self else {
return
}
self.share(rootRecord: rootRecord, completion: completion)
}
If that's not the problem it's something with either one or both of the records themselves. If you upload the record without trying to share it, does it work?
EDIT TO ADD:
What is the CKShareTypeKey? I don't use that in my app. Also I set my system fields differently:
share?[CKShare.SystemFieldKey.title] = "Something"
Try to add this to your info.plist
<key>CKSharingSupported</key>
<true/>
There is a function that is triggered after the AccountKit authorization, it calls the Firebase Function to validate the token on Facebook and returns a userId if everything is confirmed, and registers the user if he has not yet been registered.
It works fine when Internet is available, but while offline - Firebase function does not return or throw any errors or at least nil results, and I would like it to return an error such as No internet connection or ANYTHING that could be catched.
Digging web and APIReference brought no results. Does the call of firebase function really not return anything in such cases (offline)?
func checkUserCredentials(phoneNumber: String, FBId: String, Token: String) {
functions.httpsCallable("checkUserCredentials").call(["phone":"\(phoneNumber)", "FBId":"\(FBId)", "Token":"\(Token)"])
{ (result, error) in
if let error = error as NSError?
{
if error.domain == FunctionsErrorDomain
{
let code = FunctionsErrorCode(rawValue: error.code)
let message = error.localizedDescription
}
}
if let userDoc = (result?.data as? [String: Any])?["userID"] as? String
{
DispatchQueue.main.async(execute: { self.performSegue(withIdentifier: "StartTheApp", sender: self) })
}
} }
I recommend checking for a network connection before making any network request. That way you're not dependent on the vagaries of whichever library you're using to talk to the network.
I use Reachability to check for a network connection before performing any requests (which I then perform using Alamofire). Below is a sample function to check for network:
import Reachability
...
func networkIsReachable(shouldShowAlert: Bool) -> Bool {
if let reachability: Reachability = Reachability(), reachability.connection != .none {
return true
}
if shouldShowAlert {
let alertController = UIAlertController(title: "Error", message: "No internet connection.", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "Ok", style: .default, handler: nil))
present(alertController, animated: true, completion: nil)
}
return false
}
Since I'm using this function all throughout my codebase, I even moved it into an extension so as not to violate DRY principle.
Updating your code to use this function would look like this:
func checkUserCredentials(phoneNumber: String, FBId: String, Token: String) {
guard let networkIsReachable(shouldShowAlert: true) else {
// network is not reachable, and user has been shown an error message
return
}
// now perform network request
// ...
}
i'm starting with Swift3 and i'm having a recurrent problem due to the asynchronism. But until now, i always find a solution with callback.
I have a textField and a button, when i click on the button, i check on the API if there is a existing user named as in the textField.
Using shouldPerformSegue, i return the value if the users exist or no.
I have a separated class for handling calls on the Api
class Api {
static let urlApi = "https://XXXXXXXXXXXXX"
private let CUSTOMER_ID = "XXXXXXXX"
private let CUSTOMER_SECRET = "XXXXXXXX"
private var access_token : String? = nil
private var userInfo : User?
init() {
self.connect()
}
func connect() {
// Do the connect...
}
func get(user: String, callback: #escaping (_ status: Bool) -> Void) {
Alamofire.request(URL(string: "\(Api.urlApi)/v2/users/\(user)")!,
method: .get,
parameters: nil,
encoding: URLEncoding.default,
headers: ["Authorization": "Bearer \(self.access_token!)"])
.responseJSON(completionHandler: { response in
if response.result.isFailure {
print("ERROR: GET USER", response)
callback(false)
} else {
print("SUCCESS Getting user ", user)
callback(true)
}
})
}
}
And in my shouldPerformSegue
override func shouldPerformSegue(withIdentifier identifier: String, sender: Any?) -> Bool {
var userExist : Bool? = nil
let dispatchQueue = DispatchQueue(label: "getUser")
let semaphore = DispatchSemaphore(value: 1)
dispatchQueue.sync {
self.api?.get(user: self.userTextField.text!, callback: { status in
userExist = status
print("1 USEREXIST", userExist)
})
}
semaphore.wait()
print("2 USEREXIST", userExist)
return userExist ?? false // always false because userExist == nil
}
Sorry for the function mess, i don't really find the right way to do my DispachQueue and my Semaphore .. All googling answer look that i need those
The proper way to handle this scenario would be to make the request when the user taps on the button. If there is an error, you would present some error that says the username already exists. Then they would try again.
If the request is successful and that username has not been taken, then you would call performSegueWithIdentifier. The link below shows a good demonstration of the steps to take after this. Your current implementation isn't necessary.

I am trying to do a MUC on iOS using xmpp_messenger_ios & XMPPFramework
Here is the code to join the room.
func createOrJoinRoomOnXMPP(){
// location has named array of lat and long
NSLog("Creating room on XMPP")
let roomJID: XMPPJID = XMPPJID.jidWithString(self.roomID + "#conference.ip-172-31-41-100")
let roomData: XMPPRoomCoreDataStorage = XMPPRoomCoreDataStorage.sharedInstance()
let chatRoom = XMPPRoom.init(roomStorage: roomData, jid: roomJID, dispatchQueue: dispatch_get_main_queue())
chatRoom.activate(OneChat.sharedInstance.xmppStream)
chatRoom.addDelegate(self, delegateQueue: dispatch_get_main_queue())
// let history = DDXMLElement.elementWithName("history")
// // Get lst messegs of the room
// history.addAttributeWithName("maxstanzas", stringValue: "10")
chatRoom.joinRoomUsingNickname(OneChat.sharedInstance.xmppStream!.myJID.user, history: nil)
}
as soon as this block executes I get an error in this code:
extension OneMessage: XMPPStreamDelegate {
public func xmppStream(sender: XMPPStream, didSendMessage message: XMPPMessage) {
if let completion = OneMessage.sharedInstance.didSendMessageCompletionBlock {
completion(stream: sender, message: message)
}
//OneMessage.sharedInstance.didSendMessageCompletionBlock!(stream: sender, message: message)
}
public func xmppStream(sender: XMPPStream, didReceiveMessage message: XMPPMessage) {
let user = OneChat.sharedInstance.xmppRosterStorage.userForJID(message.from(), xmppStream: OneChat.sharedInstance.xmppStream, managedObjectContext: OneRoster.sharedInstance.managedObjectContext_roster())
if !OneChats.knownUserForJid(jidStr: user.jidStr) { // <<< ERROR LINE
OneChats.addUserToChatList(jidStr: user.jidStr)
}
if message.isChatMessageWithBody() {
OneMessage.sharedInstance.delegate?.oneStream(sender, didReceiveMessage: message, from: user)
} else {
//was composing
if let _ = message.elementForName("composing") {
OneMessage.sharedInstance.delegate?.oneStream(sender, userIsComposing: user)
}
}
}
}
fatal error: unexpectedly found nil while unwrapping an Optional value
I have noticed that as soon as the connection is made to chat room it fetches previous messages, and thus the above code is executed.
Please help me out is doing a MUC for room chat on ios. I have searched and have not found any solution.
thanks
I solved this by this temporary solution.
extension OneMessage: XMPPStreamDelegate {
public func xmppStream(sender: XMPPStream, didSendMessage message: XMPPMessage) {
if let completion = OneMessage.sharedInstance.didSendMessageCompletionBlock {
completion(stream: sender, message: message)
}
//OneMessage.sharedInstance.didSendMessageCompletionBlock!(stream: sender, message: message)
}
public func xmppStream(sender: XMPPStream, didReceiveMessage message: XMPPMessage) {
NSLog("This is blocked")
// let user = OneChat.sharedInstance.xmppRosterStorage.userForJID(message.from(), xmppStream: OneChat.sharedInstance.xmppStream, managedObjectContext: OneRoster.sharedInstance.managedObjectContext_roster())
//
// if !OneChats.knownUserForJid(jidStr: user.jidStr) {
// OneChats.addUserToChatList(jidStr: user.jidStr)
// }
//
// if message.isChatMessageWithBody() {
// OneMessage.sharedInstance.delegate?.oneStream(sender, didReceiveMessage: message, from: user)
// } else {
// //was composing
// if let _ = message.elementForName("composing") {
// OneMessage.sharedInstance.delegate?.oneStream(sender, userIsComposing: user)
// }
// }
}
}
Blocking the OneMessage.swift code.
and handling the incoming messages in my ViewController.
This is not the right way to do it. but until ProcessOne give support for MUC this can be done.
Unwrapping that causes nil happens on:
user (return value of userForJID method is XMPPUserCoreDataStorageObject! )
jidStr (the type is String!)
Investigate which one happens to be nil.
Possible causes of user to be nil
- Nil value of jid or managedObjectContext is used in userForJID(:xmppStream:managedObjectContext)`
To find out which one is nil, simply do this:
guard let user = OneChat.sharedInstance.xmppRosterStorage.userForJID(message.from(), xmppStream: OneChat.sharedInstance.xmppStream, managedObjectContext: OneRoster.sharedInstance.managedObjectContext_roster())
else { fatalError("user is nil") }
guard let userJIDStr = user.jidStr
else { fatalError("jidStr is nil") }
I think you need to understand XMPP MUC first, read this doc.
When you send a message to MUCRoom, the serve will broadcast the message to all the members, including yourself.
And here message.from() = room.jid BUT NOT user.jid.
That's why the user you tried to get from roster is nil.
How can I validate a form after a RAC Command or a button click? I have this somewhere in my View Model
self.executeLoginRacCommand = RACCommand(enabled: activateButtonSignal, signalBlock: { (any : AnyObject!) -> RACSignal! in
return self.executeLoginAPI()
})
//My question is here, how can I display an alert to my view controller saying may email is invalid.
//MARK: - Execute Login API
private func executeLoginAPI() -> RACSignal {
if self.isEmailValid(self.email) {
return self.signInServices.signInAPIService.signInAPISignal(self.email, password: self.password)
} else {
self.errorMessage = "Please insert a valid email"
return RACSignal.empty()
}
}
//MARK: - Is Email Valid
func isEmailValid(email: String) -> Bool {
let emailRegEx = "^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+#[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$"
let emailTest = NSPredicate(format:"SELF MATCHES %#", emailRegEx)
return emailTest.evaluateWithObject(email)
}
I access it in my View Controller like this:
self.signInButton.rac_command = self.signInViewModel.executeLoginRacCommand
Can you please suggest a good way of validating an invalid email and display alert after a button click? Thanks in advance!
In your else branch, you are returning an empty RACSignal.
Instead, return the a RACSignal that sends the error (RACSignal.error(<the error>)).
In your ViewController, you can subscribe to the errors property of self.executeLoginRacCommand and display the error to the user.
