i am creating app like as trucaller. Everything is completed, only one issue remaining. issue is that how to reload application extension after add new contact number from server in app. first of all, i enter some static number in the array then after i store it in userdefault. i got this by app-groups functionality. i want that when user synchronize their contact in my application, i want reload contact list.
this is my code
manager.reloadExtension(withIdentifier: extensionIdentifer, completionHandler: { error in
print("error \(error?.localizedDescription)")
if let _ = error{
print("A error \(error?.localizedDescription as String!)");
}
})
this is give me error like below
"sqlite3_step for query 'INSERT INTO PhoneNumberBlockingEntry
(extension_id, phone_number_id) VALUES (?, (SELECT id FROM PhoneNumber
WHERE (number = ?)))' returned 19 (2067) errorMessage 'UNIQUE
constraint failed: PhoneNumberBlockingEntry.extension_id,
PhoneNumberBlockingEntry.phone_number_id'"
Jaydeep: Call your new contact web service or synchronize contacts in application and just reload extension as -
CXCallDirectoryManager.sharedInstance.getEnabledStatusForExtension(withIdentifier: "com.compname.sampleapp", completionHandler: { (enabledStatus,error) ->
Void in if let error = error {
print(error.localizedDescription)
}
CXCallDirectoryManager.sharedInstance.reloadExtension(withIdentifier:"com.compname.sampleapp", completionHandler: {
(error) ->
Void in if let error = error {
print(error.localizedDescription)
}
DispatchQueue.main.async {
self.hud?.hide(animated: true)
}
})
print("No error")
})
Let me know still issue getting. I have done this and working fine.

I want to handle a friend request in my app written in Swift using Firebase. In my database, this means that the user sending the request needs to add the other user to their "sentRequests" dictionary, and the user receiving the request needs to add the user sending the requests to their "receivedRequests" dictionary. The problem is, if the user sending the request has a faulty connection and only does the first part, then it might cause issues. Either both writes should happen or none. What can I do to fix this? I included my code below for reference, but honestly if someone just sends me a good tutorial or answer here that would be just has helpful as correctly rewriting my code.
static func sendRequestFromCurrentUser(toUser userThatRequestWasSentTo : User, succeeded : #escaping (Bool)->Void ){
let ref = Database.database().reference().child("users").child(User.current.uid).child("sentRequests").child(userThatRequestWasSentTo.uid)
ref.setValue(userThatRequestWasSentTo.toDictionary(), withCompletionBlock: {(error, ref) in
if error == nil{
let currentUserRef = Database.database().reference().child("users").child(userThatRequestWasSentTo.uid).child("receivedRequests").child(User.current.uid)
currentUserRef.setValue(User.current.toDictionary(), withCompletionBlock: {(error, ref) in
if error == nil{
succeeded(true)
}
else{
succeeded(false)
}
})
}
else{
succeeded(false)
}
})
}
So I stole this from the Firebase blog and got it to match my code. The answer is fairly intuitive, I just hadn't considered it. Basically you just create a reference to the top level of your database and specify the paths you want to write to in the dictionary (so not by creating specific references with child()), and then just call updateChildValues().
static func sendRequestFromCurrentUser(toUser userThatRequestWasSentTo : User, succeeded : #escaping (Bool)->Void ){
let ref = Database.database().reference()
// Create the data we want to update
var updatedUserData : [String : Any] = [:]
updatedUserData["users/\(User.current.uid)/sentRequests/\(userThatRequestWasSentTo.uid)"] = userThatRequestWasSentTo.toDictionary()
updatedUserData["users/\(userThatRequestWasSentTo.uid)/receivedRequests/\(User.current.uid)"] = User.current.toDictionary()
// Do a deep-path update
ref.updateChildValues(updatedUserData, withCompletionBlock: { (error, ref) in
if let error = error {
print("Error updating data: \(error.localizedDescription)")
succeeded(false)
}
else{
succeeded(true)
}
})
}
I'm trying to get the users first name using cloud kit however the following code is not getting the users first name and is leaving firstNameFromFunction variable empty. Does anyone know how to achieve this in iOS 10?
let container = CKContainer.default()
container.fetchUserRecordID { (recordId, error) in
if error != nil {
print("Handle error)")
}else{
self.container.discoverUserInfo(
withUserRecordID: recordId!, completionHandler: { (userInfo, error) in
if error != nil {
print("Handle error")
}else{
if let userInfo = userInfo {
print("givenName = \(userInfo.displayContact?.givenName)")
print("familyName = \(userInfo.displayContact?.familyName)")
firstNameFromFunction = userInfo.displayContact?.givenName
}else{
print("no user info")
}
}
})
}
}
the permission screen that comes up when asking for the first time, IMO, is very poorly worded. They need to change that. It says "Allow people using 'your app' to look you up by email? People who know your email address will be able to see that you use this app." This make NO sense. This has nothing to do with asking the user to get their iCloud first name, last name, email address.
Speaking of email address - this and the phone number from the lookupInfo property is missing - i.e. set to nil, even though those values are legit and correct. Filing a bug tonight.
First, you will need to request permission to access the user's information.
Then, you can use a CKDiscoverUserIdentitiesOperation. This is just like any other CKOperation (eg. the modify record operation). You just need to create a new operation with the useridentitylookupinfo. Then you will also need to create a completion block to handle the results.
Here is an example function I created:
func getUserName(withRecordID recordID: CKRecordID,
completion: #escaping (String) -> ()) {
if #available(iOS 10.0, *) {
let userInfo = CKUserIdentityLookupInfo(userRecordID: recordID)
let discoverOperation = CKDiscoverUserIdentitiesOperation(userIdentityLookupInfos: [userInfo])
discoverOperation.userIdentityDiscoveredBlock = { (userIdentity, userIdentityLookupInfo) in
let userName = "\((userIdentity.nameComponents?.givenName ?? "")) \((userIdentity.nameComponents?.familyName ?? ""))"
completion(userName)
}
discoverOperation.completionBlock = {
completion("")
}
CKContainer.default().add(discoverOperation)
} else {
// iOS 10 and below version of the code above,
// no longer works. So, we just return an empty string.
completion("")
}
}
First you need to ask the user for permission to be discovered.
Use CKContainer.default().requestApplicationPermission method passing .userDiscoverability on applicationPermission parameter.
The CKContainer.default().discoverUserInfo method is deprecated on iOS 10. Instead use CKContainer.default().discoverUserIdentity method.
Do something like:
CKContainer.default().requestApplicationPermission(.userDiscoverability) { (status, error) in
CKContainer.default().fetchUserRecordID { (record, error) in
CKContainer.default().discoverUserIdentity(withUserRecordID: record!, completionHandler: { (userIdentity, error) in
print("\(userIdentity?.nameComponents?.givenName)")
print("\(userIdentity?.nameComponents?.familyName)")
})
}
}
I can fetch the userRecordID, but I get an error whenever I try to fetch the record associated with that ID. Any suggestions? Code and error below:
myContainer.fetchUserRecordID { (thisID, thisError) in
if let userError = thisError {
print("DEBUG: error getting user id; \(userError)")
} else {
if let userID = thisID {
self.publicDatabase.fetch(withRecordID: userID, completionHandler: { (fetchedUser, fetchedError) in
if let thisError = fetchedError {
print("DEBUG: error getting user record; \(thisError)")
}
DEBUG: error getting user record; <CKError 0x174045010: "Internal Error" (1/5001); "Couldn't get a PCS object to unwrap encrypted data for field encryptedPublicSharingKey: (null)">
Error in the code, or my fault for trying beta software (iOS 10, Swift 3 & xCode-beta 8.0 beta 2 (8S162m)
From your example it is not clear if self.publicDatabase is equal to myContainer.publicCloudDatabase.
Make sure you fetch it from the same container's database, otherwise it will obviously not work.
myContainer.fetchUserRecordID { userID, error in
guard error == nil else {
print("DEBUG: error getting user id; \(userError)")
return
}
guard let userRecID = userID else {
print("DEBUG: Can't unwrap userID")
return
}
myContainer.publicCloudDatabase.fetch(withRecordID: userRecID, completionHandler: { (fetchedUser, fetchedError) in
//handle the error and the user
print("DEBUG: User fetch FINISHED!", fetchedUser)
})
}
I needed to change from publicDatabase to privateDatabase.
self.publicDatabase.fetch(withRecordID: userID, completionHandler: { (fetchedUser, fetchedError) in
to
self.privateDatabase.fetch(withRecordID: userID, completionHandler: { (fetchedUser, fetchedError) in
I need the identifier of a newly created contact directly after the save request. The use case: Within my app a user creates a new contact and give them some attributes (eg. name, address ...) after that he can save the contact. This scenario is working as aspected. My code looks like this:
func createContact(uiContact: Contact, withImage image:UIImage?, completion: String -> Void)
{
let contactToSave = uiContact.mapToCNContact(CNContact()) as! Cnmutablecontawctlet
if let newImage = image
{
contactToSave.imageData = UIImageJPEGRepresentation(newImage, 1.0)
}
request = CNSaveRequest()
request.addContact(contactToSave, toContainerWithIdentifier: nil)
do
{
try self.contactStore.executeSaveRequest(request)
print("Successfully saved the CNContact")
completion(contactToSave.identifier)
}
catch let error
{
print("CNContact saving faild: \(error)")
completion(nil)
}
}
The Contact Object (uiContact) is just an wrapper of CNContact.
In the closure completion I need to return the identifier but on this time I have no access to them, because he is creating by the system after the write process.
One solution could be to fetch the newly saved CNContact with predicate
public func unifiedContactsMatchingPredicate(predicate: NSPredicate, keysToFetch keys: [CNKeyDescriptor]) throws -> [CNContact]
but this seems to me like a bit unclean because this contact could have only a name and more than one could exist. Something like a callback with the created identifier would be nice. But there isn´t.
Is there a other way to solve this problem?
This may be a little late but in case someone needs this.
By using the latest SDK (iOS 11), I was able to get the identifier just by:
NSError *error = nil;
saveReq = [[CNSaveRequest alloc] init];
[saveReq addContact:cnContact toContainerWithIdentifier:containerIdentifier];
if (![contactStore executeSaveRequest:saveReq error:&error]) {
NSLog(#"Failed to save, error: %#", error.localizedDescription);
}
else
{
if ([cnContact isKeyAvailable:CNContactIdentifierKey]) {
NSLog(#"identifier for new contact is: %#", cnContact.identifier);
// this works for me everytime
} else {
NSLog(#"CNContact identifier still isn't available after saving to address book");
}
}
swift 4
This is the way to get contact id when creating contact
do {
try store.execute(saveRequest)
if contactToAdd.isKeyAvailable(CNContactIdentifierKey) {
print(contactToAdd.identifier) // here you are getting identifire
}
}
catch {
print(error)
}
I'm developing an iOS project using Parse.com as backend server.
Basically, I'm currently implementing a very basic feature which just simply retrieve some objects with simple condition.
However, the objects can only be correctly retrieved the first time. No matter how I changed any values in Parse "Core" via Web, I still cannot get updated values by refreshing in the app.
For example, I have a class called "Event", the fields are changed from Parse server, but the result I retrieve are never updated.
let eventServerQuery = Event.query()
// I tried to clear all cached results
PFQuery.clearAllCachedResults()
eventServerQuery?.whereKey(EventFields.Campus.rawValue, equalTo: campus!)
eventServerQuery?.findObjectsInBackgroundWithBlock({ (allEvents, error) -> Void in
self.refreshControl?.endRefreshing()
self.toggleRefreshButtonWithSpinner(false)
if error != nil {
print(error?.localizedDescription)
}else{
if allEvents?.count > 0 {
// Display on the map
for eventObject in allEvents! {
let event = Event.initializeFieldsFromPFObject(eventObject)
self.delegate?.addEventToMap(event)
self.events.append(event)
print("\(event.updatedAt)")
print("\(event.title) has \(event.numberOfTasks) tasks")
}
// Event TVC data source
self.tableView.reloadData()
}
}
})
If I delete the app in my device and run the project again, it will of course reload everything from scratch, so that the data will become correct again...
Any help will be appreciated!
Finally, I worked out by myself. I found that whenever the PFObject was pinned, its fields will not be updated. The solution is that the object need to be unpinned before retrieve from server.
Event.unpinAllInBackground(events, block: { (success, error) -> Void in
if error != nil {
print(error?.localizedDescription)
}else{
self.events.removeAll()
let eventServerQuery = Event.query()
eventServerQuery?.whereKey(EventFields.Campus.rawValue, equalTo: self.campus!)
eventServerQuery?.findObjectsInBackgroundWithBlock({ (allEvents, error) -> Void in
print("Debug: retrieving events from server")
self.refreshControl?.endRefreshing()
self.toggleRefreshButtonWithSpinner(false)
if error != nil {
print(error?.localizedDescription)
}else{
if allEvents?.count > 0 {
// Display on the map
for eventOnline in allEvents! {
let event: Event = eventOnline as! Event
event.pinInBackground()
self.delegate?.addEventToMap(event)
self.events.append(event)
}
// Event TVC data source
self.tableView.reloadData()
}
}
})
}
})
Welcome to add comments here regarding the internal logic of Parse library, as sometimes it is not quite clear I think.
