I'm trying to create simple autocomplete UI widget:
self.autocompleteQuery = [[SPGooglePlacesAutocompleteQuery alloc] initWithApiKey:[GlobalConfig sharedInstance].kGoogleBrowserKey];
self.autocompleteQuery.language = kFFAutocompleteQueryLanguage;
self.autocompleteQuery.types = SPPlaceTypeAddress;
self.autocompleteQuery.location = [FFAppDataHelper coordinatesForMoscow];
self.autocompleteQuery.radius = [GlobalConfig sharedInstance].kMoscowRadius;
self.autocompleteQuery.countryCode = #"RU";
Then I want to get all values for input string from UITextField on 'valueChanged' event:
self.autocompleteQuery.input = [streetName stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
[self.autocompleteQuery fetchPlaces:^(NSArray *places, NSError *error) {
[self loaderStopAnimating];
if (places) {
//do some stuff
} else {
FFError *detectedError = [FFError errorWithNSError:error];
[self showErrorMessage:[detectedError errorMessage]];
}
}];
So when I type 'k' I get response with streets and if I add next char to my text field I receive OVER_QUERY_LIMIT every time. I've tried it on simulator and devices with the same result. And it starts working again after 10-20 sec. I don't use loops or smth similar, I just want to get suggestions for input string in real time, but I can't get it because of error. What should I do to avoid it?
For the web service request, use a key.
Follow this :https://developers.google.com/maps/documentation/geocoding/start#api_key
Doc says:
Note: Maps for Work users must include client and signature parameters with their requests instead of a key.
All Geocoding API applications should use an API key. Including a key in your request:
Allows you to monitor your application's API usage in the Google Developers Console. Enables per-key instead of per-IP-address quota limits. Ensures that Google can contact you about your application if necessary. The Geocoding API uses an API key to identify your application. API keys are managed through the Google APIs console. To create your key:
Visit the APIs console at Google Developers Console and log in with your Google Account. Click the Services link from the left-hand menu in the APIs Console, then activate the Geocoding API service. Once the service has been activated, your API key is available from the API > Access page, in the Simple API Access section. Geocoding API applications use the Key for server apps. To specify a key in your request, include it as the value of a key parameter.
Note: By default, a key can be used from any server. We strongly recommend that you restrict the use of your key by IP address to servers that you administer. You can specify which IP addresses are allowed to use your API key by clicking the Edit allowed referers... link in the API console.
Note: HTTPS is enforced for requests that include an API key.

as written in the title is it possible change username of a Amazon Cognito user? I can't find anything in documentation
It is possible to update the preferred_username of a Cognito User using the iOS SDK, using the updateAttributes API call. However, kindly note that you would not be able to modify the username of a user. Quoting the official AWS documentation,
The username value is a separate attribute and not the same as the
name attribute. A username is always required to register a user, and
it cannot be changed after a user is created.
But, the preferred_username value can indeed be changed, and a sample code to change the preferred username using the iOS SDK, as per the official documentation is stated as follows:
AWSCognitoIdentityUserAttributeType * attribute = [AWSCognitoIdentityUserAttributeType new];
attribute.name = #"preferred_username";
attribute.value = #"John User";
[[user updateAttributes:#[attribute]] continueWithSuccessBlock:^id _Nullable(AWSTask<AWSCognitoIdentityUserUpdateAttributesResponse *> * _Nonnull task) {
//success
return nil;
}];
I would also like to state that the AWS API documentations for the iOS SDK are rather minimal, and I would recommend developers to go through the SDK source code whenever in doubt.

Twilio developer evangelist here.
The Twilio Java library is not intended for use within Android projects.
The issue here is that you should not be storing your credentials within your application. A malicious user could decompile your application, take your credentials and abuse them.
Instead, you should create a server (or use some sort of serverless environment, like Twilio Functions) that can run this code and return the token. You should then make an HTTP request from your Android application to fetch that token. Check out the Twilio Programmable Chat Android Quickstart to see how it's done there.
I want to build a client where I can display events in a given Exchange Calendar.
I read about ActiveSync and Exchange Web Services, and apparently Exchange Web Services is the way to access the calendars, however, I cannot find any documentation on how to go about fetching the data (i.e. how to authenticate with the Exchange server, how to retrieve the data (through HTTP POST requests?), and so on).
Am I on the right track or am I missing a different API that is used to access an Exchange calendar? I would prefer, if I didn't have to use Apple's Event Kit since that would require the user to sync his account with the iOS device first.
EWS is the way to go. You can read any user's calendar (presuming you have credentials or impersonation authority), and can also subscribe to notifications when a calendar changes. EWS can be accessed from .NET apps, Java, and other languages. Of course the easiest way to go would be using C# and the EWS Managed API, but there are a lot of alternatives outside the Windows world. You can start here, but you'll probably want to search for you specific technology. There's a lot of info out there.
In JAVA EWS api , i used below code:
public static void getAllMeetings() throws Exception {
try {
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date startDate = formatter.parse("2016-01-01 00:00:00");
SearchFilter filter = new SearchFilter.IsGreaterThanOrEqualTo(ItemSchema.LastModifiedTime,startDate);
FindItemsResults<Item> findResults = service.findItems(WellKnownFolderName.Calendar, filter, new ItemView(1000));
System.out.println("|------------------> meetings count = " + findResults.getTotalCount());
for (Item item : findResults.getItems())
{
Appointment appt = (Appointment)item;
//appt.setStartTimeZone();
System.out.println("TimeZone====="+appt.getTimeZone());
System.out.println("SUBJECT====="+appt.getSubject());
System.out.println("Location========"+appt.getLocation());
System.out.println("Start Time========"+appt.getStart());

I can get all meeting schedules.
Our service is using Google App Engine as our backend, and we're now implementing an upload-function for images etc.
Using the answers from several different questions here on stack, I have made it working, but not completely as I want. We are not using the built-in OAuth etc, and for now we want the storage to be public, but not entirely public. We would like to limit it to users of our own app (I.E no authentication). In the Cloud-console we can create an API-key for iOS. When doing this, we copy the API-key to the app, and pass it along with every upload-request. This is currently working, when the bucket-permission is set to allUsers - WRITE
However, inside the API-key, we can supply our app's own Bundle Identifier, so that, supposedly, only requests from our app is allowed. (App Store ID/URL is also permitted, apparently).
Adding this bundle-id does nothing as long as the bucket has the permission allUsers - WRITE. If I change the bundle-id to not match the actual bundle-id, it still works. So which permission should it use for the bucket to make the bundle-id in the API-key apply? And what should be sent along in the upload-code on iOS (acl?)?.
If I remove the allUsers-permission, and use something else, I get this error when trying to upload:
{message:"There is a per-IP or per-Referer restriction configured
on your API key and the request does not match these
restrictions. Please use the Google Developers Console
to update your API key configuration if request from this
IP or referer should be allowed." data:[1] code:403}}
This is how I'm using it right now (though I have tried several different things, all picked up from different questions/answers):
GTLServiceStorage *serv = [[GTLServiceStorage alloc] init];
serv.additionalHTTPHeaders = [NSDictionary dictionaryWithObjectsAndKeys:
#"[my project id]", #"x-goog-project-id",
#"application/json-rpc", #"Content-Type",
#"application/json-rpc", #"Accept", nil];
serv.APIKey = #"[my iOS API key, gotten from console, (linked to bundle-id?)]";
serv.retryEnabled = YES;
GTLStorageBucket *bucket = [[GTLStorageBucket alloc] init];
bucket.name = #"[my bucket]";
GTLUploadParameters *params = [GTLUploadParameters uploadParametersWithFileHandle:fileHandle MIMEType:#"image/jpeg"];
GTLStorageObject *storageObject = [[GTLStorageObject alloc] init];
storageObject.name = #"testFile.jpg";
//I have no idea what I'm doing with the following stuff, but I've tried several things:
GTLStorageObjectAccessControl *objAccessControl
= [GTLStorageObjectAccessControl new];
//This is working
objAccessControl.entity = #"allUsers";
objAccessControl.email = #"[my app-id]#project.gserviceaccount.com";
objAccessControl.role = #"OWNER";
//If I try this instead, it is not working.
//objAccessControl.domain = #"[my app-id].apps.googleusercontent.com";
//objAccessControl.role = #"WRITER";
//Probably because it's bullshit, I have no idea what I'm doing.
storageObject.acl = #[objAccessControl];
[...] //Bucket and upload and stuff. It seems like it's the ACL-thing above that's not working..
It seems like I have to connect the permissions on the bucket to the iOS API Key somehow, but I don't know if it's even possible.
What I want: All users to be able to use the cloud, given that they are requesting it from my iOS app.
As this question never got an answer I'll add one here, based on the information currently in the post.
The reason you got the error 'There is a per-IP or per-Referer restriction..' when calling the GCS API with the iOS API Key is simply because the GCS API doesn't work with API Keys for private data, only Bearer Tokens (ie. using OAuth). There isn't anything you could have done to make the API Key work with the GCS API directly with private data. The reason it worked when you had 'allUsers - WRITE' set as the ACL is simply because that ACL allows public access.
To access the private data without user intervention requires a Service Account, however the Google APIs Objective-C Client only supports OAuth2 Client IDs. The rationale being that Service Accounts are intended for server-side authentication only. Using a Service Account in a client would involve distributing the private key along with the app, which could easily be compromised. For reference, here's a sample of how you might authorize the GCS service using OAuth:
NSString *keychainItemName = #"My App";
NSString *clientID = <your-client-id>;
NSString *clientSecret = <your-client-secret>;
// How to check for existing credentials in the keychain
GTMOAuth2Authentication *auth;
auth = [GTMOAuth2WindowController authForGoogleFromKeychainForName:kKeychainItemName
clientID:clientID
clientSecret:clientSecret];
...
// How to set up a window controller for sign-in
NSBundle *frameworkBundle = [NSBundle bundleForClass:[GTMOAuth2WindowController class]];
GTMOAuth2WindowController *windowController;
windowController = [GTMOAuth2WindowController controllerWithScope:kGTLAuthScopeStorageDevstorageFullControl
clientID:clientID
clientSecret:clientSecret
keychainItemName:kKeychainItemName
resourceBundle:frameworkBundle];
[windowController signInSheetModalForWindow:[self window]
completionHandler:^(GTMOAuth2Authentication *auth,
NSError *error) {
if (error == nil) {
self.storageService.authorizer = auth;
}
}];
...
// Initialize service with auth
GTLServiceStorage *serv = [[GTLServiceStorage alloc] init];
serv.authorizer = auth;
All of this was taken from the storage sample on the google-api-objectivec-client GitHub page, so you can refer to it for a complete example with context.
This still leaves the question of how to implement access to GCS from iOS without user authorization. The short answer to this is that the iOS Key can be used to restrict access to your own backend API hosted on Google Cloud Endpoints, and that backend application can authorize against GCS using a Service Account (usually the Application Default Service Account). The Cloud Storage Client Library Examples page has samples using the default credentials for different languages.
Further details on how to implement an Endpoints API for this purpose are probably getting outside of the scope of this question, but this should serve as a good starting point.
What's the best api/resource to get a zip +4 from an address?
I don't want something that needs to be downloaded and updated from time to time; I want one that's updated automagically.
The goal is to look up state and federal officials without getting "duplicate" positions.
have you tried Google Maps JavaScript API V3
UPDATED:
in responce to your comment
this is easy as count 1, 2 , 3 ;)
take a look at this:
http://maps.google.com/maps/api/geocode/json?address=Winnetka&sensor=false
you need to looking for google map geocoding service! ( Viewport Biasing )
http://code.google.com/intl/it-IT/apis/maps/documentation/geocoding/
example code would be:
using jQuery
$(function() {
$.getJSON("http://maps.google.com/maps/api/geocode/json?address=Winnetka&sensor=false",
function(data) {
var zip_code = data.results[0].long_name;
alert(zip_code);
});
});
Yahoo has a zip + 4 in thier API, limit 5000 request per day.
Yahoo GeoCoding
The USPS has an API for finding/checking zip codes (among other things).
http://www.usps.com/webtools/address.htm
I've used Endicia at past jobs. It is a network HTTP-based API. (I can't remember if it was SOAP or REST.)
Apple provide brilliant facility to get zip+4code from lattitude and longitude with reverse geocoder -
- (void)getPlaceMarkInfo
{
CLLocationCoordinate2D coordinate;
coordinate.latitude = your lattitude;
coordinate.longitude = your longitude;
MKReverseGeocoder *RevGeoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate];
RevGeoCoder.delegate = self;
[RevGeoCoder start];
}
#pragma mark MKReverseGeocoderDelegate:
- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
{
NSLog(#"YOUR STATE IS - %#",[placemark.addressDictionary valueForKey:#"State"]);
NSDictionary *dictAddress = placemark.addressDictionary;
NSString *strZipPlus4Code = [NSString
stringWithFormat:#"%#-%#",[dictAddress valueForKey:#"ZIP"],
[dictAddress valueForKey:#"PostCodeExtension"]];
strStateName = [placemark.addressDictionary valueForKey:#"State"];
}
- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error
{
NSLog(#"REVERSE GEOCODER FAILED");
}
Previous answers have included some really good information, most importantly:
USPS API can only be used if you're shipping through USPS (from their terms of service: "User agrees to use the USPS Web site, APIs and USPS data to facilitate USPS shipping transactions only.")
ZIP Codes are adjusted/updated fairly frequently, so it would be important to have the most current data. (More info about how often to re-validate your addresses here)
You also said you want something that doesn't need to be installed and kept updated.
With those qualifications in mind, I would suggest LiveAddress API. It's a cloud-based, automatically updated API that returns, among over 40 other datapoints, ZIP+4 data on your addresses. It can handle thousands of addresses per second, so it's super-fast and easy to use. If you have a list of address you want to work though (rather than one at a time), you might want LiveAddress for Lists, which lets you upload and process a whole list at once.
Disclosure: I work at SmartyStreets, the company that provides LiveAddress.
In reference of Yahoo BOSS GEO Api:
http://yboss.yahooapis.com/geo/placefinder?location=170+South+Market+St.,+San+Jose,+CA
Make a GET request with following authorization HEADER
Example of using OAuth in HTTP Header:
Authorization: OAuth realm="http://yboss.yahooapis.com/",oauth_consumer_key="dj0yJmk9QnFUYVRUSWtRZEhsJmQ9WVdrOVFrYzFja2x4TkdNbWNHbzlNVEExTWpFMk1ESTJNZy0tJnM9Y29uc3VtZXJzZWNyZXQmeD1lNA--",oauth_nonce="ZDQDDVLFCWKCZ0BD",oauth_signature_method="HMAC-SHA1",oauth_timestamp=" 1367827192",oauth_version="1.0",oauth_signature="phP2dNiCmvwpK4M6G%2F85KnnvTXo%3D"
where:
Authentication for BOSS Geo queries requires OAuth information in the HTTP header OR through parameters in the GET request. There are six elements that are required for authorization:
oauth_version=1.0 – The standard of OAuth supported by BOSS Geo.
oauth_timestamp= – The timestamp is expressed in the number of seconds since January 1, 1970 00:00:00 GMT. The timestamp value MUST be a positive integer and MUST be equal to or greater than the timestamp used in previous requests. The timestamp can be reused for up to 5 minutes. Important: After 5 minutes a fresh timestamp must be supplied.
oauth_nonce – is a random string, uniquely generated for all requests for a specific timestamp. This helps verify that a request has never been made before and helps prevent replay attacks when requests are made over a non-secure channel (such as HTTP).
oauth_consumer_key= – obtained from YDN during the BOSS project registration process. This is unique to the developer. Please follow the directions on the displayed key page and copy the entire key from YDN. If you do not copy the entire key, this results in a "Consumer Key rejected" error.
oauth_signature_method=HMAC-SHA1 – (specific algorithm used for BOSS OAuth calls).
oauth_signature – can be generated by an OAuth library. A list of supported OAuth libraries is available here: http://oauth.net/code. Over a dozen languages are supported.
You will get zip+4 code in Response under "postalcode" key.
