In Firebase Analytics, there is a user property called user_pseudo_id, which is automatically set by Firebase, and it seems to fit our needs.
The doc says:
The pseudonymous id (e.g., app instance ID) for the user.
but when I get Instance ID using InstanceID.instanceID().instanceID(handler:) it give different value from what we see in Big Query.
Any thoughts on how to get it? Thanks!
You should be using the appInstanceID method of FIRAnalytics class.
NSString *instanceID = [FIRAnalytics appInstanceID];
NSLog(#"INSTANCE ID: %#", instanceID);
Using Swift 5 you can get this as follows.
let instanceID = Analytics.appInstanceID()
print(instanceID)

We are creating a pin in a specific Board by using the method
createPinWithImageđź”—onBaord:description:progress:withSuccess:andFailure:
We read in the documentation (here: https://developers.pinterest.com/docs/api/overview/ and here: https://github.com/pinterest/ios-pdk/blob/master/Pod/Classes/PDKClient.h#L417) that this method should return a PDKResponseObject *responseObject with the ID, URL, clickthrough URL and description of the created Pin.
We have been creative enough to try to access the ID of the Pin and its URL using any possible key (#"id", #"identifier", #"url", #"NSUrl") but the values returned are always nil. In fact the PDKResponseObject returns only 2 keys: Board ID and Pin Description.
What should we do to access the ID or, at the very least, the URL of the newly created Pin?
Does anybody have the same issue?
Despite multiple attempts and after having tried to discuss this issue with the Pinterest development Team, this still remains.
Testing a solution becomes also extremely difficult considering the new limitation Pinterest has imposed on not approved apps (which include all apps under development by definition).
For now, I only found a way around by calling a new request to get all pins in a specific board and get the first in the resulting array (which is the last posted):
//Create pin in Pinterest
[[PDKClient sharedInstance]createPinWithImage:image link:urlToShare
onBoard:reference description:message progress:nil
withSuccess:^(PDKResponseObject *responseObjectCreation) {
//Previous block does not return pin id so a new call is required
[[PDKClient sharedInstance]getBoardPins:reference fields:[NSSet
setWithArray:#[#"link"]] withSuccess:^(PDKResponseObject
*responseObject) {
//Get id of last pin
NSArray *pinIDs = [[NSArray arrayWithArray:[responseObject
pins]]valueForKey:#"identifier"];
NSString *postId = [pinIDs objectAtIndex:0];
}];
}];
By the way, the right key for the pin ID is "identifier" and not "id" or "ID" as said in the API documentation. Just found out by trying multiple times and checking the Pinterest Example app in GitHub.
Hope this helps other people who are fighting the same problem.
I got node in the firebase named "XXXXX".
I want to add tokenids to this node.
But in iOS I am having problem updating tokensids.
Do we got functions in iOS for appending data to iOS Firebase?
or we have to first get the token from firebase , append our token and save the token array back to node ?
Any suggestion guys ?
No, you cannot append data to an array in Firebase using any Firebase query.
But, there is a way by using dictionary as arrayObjectToAdd: true,
self.ref.child("ArrayMainNode").setValue(["arrayObjectToAdd": "true"])
To remove an array object, you can directly use
self.ref.child("ArrayMainNode").child("arrayObjectToAdd").removeValue()
You can do it this way:
let ref = FIRDatabase.database().reference(withPath: "somePath/array").child(newArrayObjectKey)
ref.setValue("true") // or whatever
Hope it helps
You can do it by this way:
let refInsert = Database.database().reference()
self.refInsert.updateChildValues(["Your node": "\(new token)"])
I have made an iOS application using built.io. There are several files uploaded in the application. However, i am unable to get the list of all the files uploaded in the app. Could anyone please help?
This can be done via BuiltFile class instance method fetchAllOnSuccess:onError:
It returns all files uploaded in your built application only if the requesting user has permission for it.
Built* builtfileObj = [Built file];
[builtfileObj fetchAllOnSuccess:^(NSArray *allFiles) {
// allFiles contains array of BuiltFiles
} onError:^(NSError *error) {
// there was an error in creating the object
// error.userinfo contains more details regarding the same
}];
To fetch all the uploads, the iOS SDK provides an instance method in the BuiltFile class. It returns an array of all the uploads.
Here's the link to the official documentation
http://static.built.io/downloads/sdk-docs/ios-docs/Classes/BuiltFile.html#//api/name/fetchAllOnSuccess:onError:
I dont know if its available in the iOS SDK but you can use the REST API to fetch it
Headers :
"application_uid: uid"
"application_api_key: api_key"
URL: GET : https://manage.built.io/v1/uploads?skip=0&limit=50&include_count=true
Params : skip and limit for pagination and include_count is for getting the total count.
The above url will fetch all types of files
But if you want only images or videos then you can use the below urls
https://manage.built.io/v1/uploads/images
https://manage.built.io/v1/uploads/videos
I hope i was helpful to you!!
Note : without the headers the API wont work
I have an iOS app that uses Firebase and currently has a few dictionaries with keys that are NSDate objects. The obvious issue with this is that NSDate draws from the device's system time, which is not universal.
With that, what's the best way to get a server timestamp (similar to Firebase.ServerValue.TIMESTAMP for the Web API) using Firebase's iOS API so that I can sort my dictionary keys chronologically?
I'm also aware of the chronological nature of IDs generated by childByAutoID, but I can't figure out the proper way to sort these in code. While they may be returned in chronological order, any time something like allKeys is called on them, the order goes out the window.
Any help with this issue would be greatly appreciated!
Update: In Firebase 3.0 + Swift, you can use
FIRServerValue.timestamp(). In Objective-C this is [FIRServerValue timestamp].
In Swift, you can now use FirebaseServerValue.timestamp() with Firebase 2.0.3+ (before 3.0).
The equivalent for Firebase.ServerValue.TIMESTAMP in iOS is kFirebaseServerValueTimestamp. Right now, this only works for Objective-C and not Swift.
In Swift, you can create your own global timestamp with
let kFirebaseServerValueTimestamp = [".sv":"timestamp"]
and then you'll be able to use kFirebaseServerValueTimestamp in the same way.
But you can only use this as the value or priority of a node. You won't be able to set it as the key name (although, I don't believe you could in the Web API either).
In general, calling allKeys on a dictionary does not guarantee order. But if you're using childByAutoID at a node, you can get back the right order by ordering the NSArray returned by allKeys lexicographically. Something like this would work:
[ref observeEventType:FEventTypeValue withBlock:^(FDataSnapshot *snapshot) {
NSDictionary *value = snapshot.value;
NSLog(#"Unsorted allKeys: %#", value.allKeys);
NSArray *sortedAllKeys = [value.allKeys sortedArrayUsingSelector:#selector(compare:)];
NSLog(#"Sorted allKeys: %#", sortedArray);
}];
This is similar to sorting an NSArray alphabetically, but when sorting the auto-generated IDs, you do not want localized or case insensitive sort, so you use compare: instead of localizedCaseInsensitiveCompare:
Caveat: Seems like the timestamp is added AFTER your object is persisted in Firebase. This means that if you have a .Value event listener set up on the location your object is persisted to, it will be triggered TWICE. Once for the initial object being stored in the location, and again for the timestamp being added. Struggled with this issue for days :(
Helpful information for anyone else who can't figure out why their event listeners are triggering twice/multiple times!
As of Firebase 4.0 you can use ServerValue.timestamp()
for example:
let ref = Database.database().reference().child("userExample")
let values = ["fullName": "Joe Bloggs", "timestamp": ServerValue.timestamp()] as [String : Any]
ref.updateChildValues(values) { (err, ref) in
if let err = err {
print("failed to upload user data", err)
return
}
}
You can get Time Stamp using FIRServerValue.timestamp().
But, Because of FIRServerValue.timestamp() listener is called two times. Listener will be called two times.
Currently, in my AppDelegate, I have an instance variable declared for GNConfig that is set up with all properties I would like to receive.
This instance of GNconfig is used by any class that makes a gracenote request.
The requests I am using are recognition from an audio stream, recognition by local file and a text search which populates an array. The array is then used for track lookups by id for the corresponding array item.
I am able to get all the content I need, except for track and album link data (always returns null).
I have tried plenty of different suggestions and guides with no luck.
Could somebody please help me out? This data is essential to my app and my app is pretty much complete except for this big obstacle.
Thanks in advance.
** edit **
This is in my appDelegate:
_gnConfig = [GNConfig init:#"XXXXXXX-XXXXXXXXXXXXXXXXXXXXXXX"];
[_gnConfig setProperty:#"content.coverArt" value:#"1"];
[_gnConfig setProperty:#"content.coverArt.sizePreference" value:#"LARGE"];
[_gnConfig setProperty:#"content.allowFullResponse" value:#"1"];
I have this in one of my class methods:
NSURL *filePath = [item valueForProperty:MPMediaItemPropertyAssetURL];
[GNOperations recognizeMIDFileFromFile:self config:[[AppDelegate sharedDelegate] gnConfig] fileUrl:filePath];
In the delegate method I have:
gracenoteResponseItem = [result bestResponse];
NSLog("%#", [gracenoteResponseItem trackLinkData]);
Some tracks may not have link data available.
Also if you are doing a local lookup then you will have to set this config option:
[publicProperties setObject:#“1"forKey:#"content.allowfullresponse"];
Unless you have explicitly had your client ID entitled for Link IDs (aka 'external' or '3rd party' IDs), you won't get any in your responses.
By default, Gracenote Open Developer client IDs aren't entitled for any external IDs. You need to coordinate with Gracenote to entitle your client ID to start receiving the desired IDs.
