It seems that there is a dictionary value I can place in the GET call that corresponds to a property on PDKPin that I can call in my success block to unpack the value, i.e. "url" = PDKPin.url "note" = PDKPin.decriptionText, however I can't find a corresponding property for "link" which is available per the documentation https://developers.pinterest.com/docs/api/pins/?
PDKClient.sharedInstance().getAuthenticatedUserPinsWithFields(Set(["url", "note", "link"]), success:
{ (responseObject :PDKResponseObject!) -> Void in
print("success /(pdk)")
let currentResponseObject = responseObject
let pins = currentResponseObject.pins
self.pinArray = pins()
for pin in self.pinArray {
if let pinAsPDKPin = pin as? PDKPin {
print(pinAsPDKPin.descriptionText)
if let safeURL = pinAsPDKPin.url {
print(safeURL)
}
let link = pinAsPDKPin.link //no such property on PDKPin
}
}
}) { (err :NSError!) -> Void in
print("error NSError: \(err)")
}
It looks kinda weird, but as per the implementation, the 'link' property(from the API) is used as 'url'(in the SDK). Check out the code here : https://github.com/pinterest/ios-pdk/blob/master/Pod/Classes/PDKPin.m#L38
So, if all that you care about is the 'link' from the API, then just access 'url' in the SDK(in PDKPin object).

Although we were able to do this Android, we haven't yet got the issuer name on iOS.
// after Microblink has looked at an image (from the camera roll)
func recognizerRunner(_ recognizerRunner: MBCRecognizerRunner, didFinishScanningWith state: MBCRecognizerResultState) {
if state == .valid { // values: .empty, .uncertain, .valid, .stageValid
let result = blinkCardRecognizer.result
DispatchQueue.main.async(execute: {() -> Void in
let details = VerificationDetails(firstSix: self.firstSix(result.cardNumber),
lastFour: self.lastFour(result.cardNumber),
name: result.owner,
brand: result.issuer)
self.delegate?.scanningSuccess(details: details)
})
}
else {
self.delegate?.scanningFailed()
}
}
The problem is that result.issuer is returning a MBCIssuer object, which I can't find any documentation for. How do I retrieve a string from a MBCIssuer?
Found it. Available from:
MBCBlinkCardUtils.issuer(toString: result.issuer)
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)")
})
}
}
Thanks in advance for any help. I am trying to get Batch items (Load multiple) items from one DynamoDb table using the AWS iOS SDK (Swift). I can load one item using the Block syntax, but I need to load 10 or more than that. I don't want to use 10 Block calls to load them individually. I tried to follow the attach stackoverflow Link (where the similar solution is given) but I am getting the following compiler error message. I come from Java background, hence could also be a syntax issue. Is it the right way to load multiple items? I don't want to use low level API. Any help, where I am going wrong. Thanks.
aws dynamodb how to use object mapper with batch get in ios

Have a try with the following codes (Swift 4.1, Feb 9th, 2018):
let dynamoDBObjectMapper = AWSDynamoDBObjectMapper.default()
var tasksList = Array<AWSTask<AnyObject>>()
for i in 1...10 {
tasksList.append(dynamoDBObjectMapper.load(AWSCards.self, hashKey: "SH_"+String(i), rangeKey: nil))
}
AWSTask<AnyObject>.init(forCompletionOfAllTasksWithResults: tasksList).continueWith { (task) -> Any? in
if let cards = task.result as? [AWSCards] {
print(cards.count)
}
else if let error = task.error {
print(error.localizedDescription)
}
return nil
}
Your question is "how to use the object mapper" but it might be more efficient for you to not use it.
However, there is a way to use it. See Niklas's answer here and here (he copy & pasted), but something about it strikes me as fishy. I want to make the assertion that it is not as fast as the built-in batch-get function, but I am unsure. I suspect that this does not complete the items in parallel, or at least not as efficiently as in BatchGetItem.
See the docs: "In order to minimize response latency, BatchGetItem retrieves items in parallel."
According to Yosuke, "Currently, AWSDynamoDBObjectMapper does not support the batch get item. You need to load one item at a time if you want to use the object mapper" as of 2016. This still seems to be the case. I am using a version a couple versions behind, but not too far behind. Someone check.
In conclusion, if you are loading one item at a time, you are likely missing out on the whole purpose of BatchGetItem (low latency).
Pulling from various sources, including John Davis's question here, I have tested and ran this BatchGetItem result. Here ya go.

I'm doing a Facebook graph call to get friends of the user that are using my app. I get the facebook ID of the user's friends back from the graph call. Below is what I'm attempting to obtain from Parse with that ID, but's it's not getting all the users back, I believe since its an async call. How can I save an array of pointers of the user's fb friends that are using the app? Thanks in advance!!
graphConnection.addRequest(requestFriends, completionHandler: { (connection: FBSDKGraphRequestConnection!, result: AnyObject!, error: NSError!) -> Void in
if result.objectForKey("friends") != nil {
// parsing dictionary to get results
let firstDict = result.objectForKey("friends")
let dataArray = firstDict!.objectForKey("data")
let myFriendsUsingTheAppCount = dataArray!.count
print("\(myFriendsUsingTheAppCount)")
let friendsArray:NSMutableArray = []
for var i = 0; i < dataArray!.count; i++ {
let friend = dataArray![i]
let friendFbObjectID = friend.objectForKey("id")!
let query = PFUser.query()
query!.whereKey("facebookID", equalTo: friendFbObjectID)
query!.findObjectsInBackgroundWithBlock({ (objects, error) -> Void in
if error == nil {
// this is where I was going to save this specific user as a pointer
} else {
// some error
}
})
// this is saving just the friend's name/fb id to an array, but I want an array of pointers to the PFUser
friendsArray.addObject(friend)
}
} else {
// fb friends is nil
print("FB friends came back nil")
}
})
This could be simplified into a single query by using whereKey:containedIn:
let facebookIDs = dataArray.map { $0.objectForKey("id")! }
let query = PFUser.query()!
query.whereKey("facebookID", containedIn: facebookIDs)
The query will now contain all users whose facebook id is in the array passed to the query.

So I'm trying to create a registration page with availability by Zip Code.
For instance, a user can only register if the service is available in their area (zip code).
So far I have a Text field for Zip Code and a button labeled "Check Availability".
I have a Parse Backend and I tested a connection to it using their setup guide and it works.
How can I go about adding Zip Codes to Parse and when a user types in that zip code that matches it'll open a new View Controller and they can register.
First method is to save zipCode that the user entered from the TextField:
var zipcodeFromUsers = customTextfield.text.toInt()
var savingObject = PFObject(className: "nameoftheclass")
savingObject["username"] = PFUser.currentUser()?.username
savingObject["zipcode"] = zipcodeFromUsers
savingObject.saveEventually { (success:Bool, error:NSError?) -> Void in
if error == nil
{
// data was saved
}
}
Second Method is to retrieve all the zipcodes from parse. So lets say that we want to query all 2344 zip codes
var needToFoundZipcode = 2344
var queryFromParse = PFQuery(className: "nameoftheclass")
queryFromParse.whereKey("zipcode", equalTo: needToFoundZipcode)
queryFromParse.findObjectsInBackgroundWithBlock { (objects:[AnyObject]?, error:NSError?) -> Void in
if error == nil
{
if let objects = objects as? [PFObject]
{
for SingleZipcode in objects
{
var singlezipcodeFound = SingleZipcode["zipcode"] as! Int
// now you could whatever you want
}
}
}
}
