I am using UIActivityViewController in my project for sharing in iOS 6.0. It shows the Email Option.
But when there is No Email Account, it does not take me to the settings page to setup my account but rather does nothing and returns NO in the "completed" boolean flag. Any ideas how to go to the settings page or any workaround for this problem.
Thanks!
This is how you do it for Twitter, you'll have to make the appropriate changes to use it for Mail:
if (![TwitterSettings hasAccounts]) {
//NSLog(#"UnAvailable");
[TwitterSettings openTwitterAccounts];
}
//
// TwitterSettings.m
//
//
#import "TwitterSettings.h"
#implementation TwitterSettings
+ (BOOL)hasAccounts {
// For clarity
return [SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter];
}
+ (void)openTwitterAccounts {
SLComposeViewController *ctrl = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
if ([ctrl respondsToSelector:#selector(alertView:clickedButtonAtIndex:)]) {
// Manually invoke the alert view button handler
[(id <UIAlertViewDelegate>)ctrl alertView:nil
clickedButtonAtIndex:kTwitterSettingsButtonIndex];
}
// [ctrl release];
}
#end

I was trying to implement Google One Tap SignIn in my project. At the first time after building the project the google one tap prompt will display. But next time onwards if we refresh the page also the prompt is not displaying.
Here is my code snippet.
import { addScript } from 'Util/DOM';
/**
* Loads One Tap Client Library
*/
const loadOneTapClientLibrary = async() => {
await addScript('https://accounts.google.com/gsi/client');
}
/**
* Loads One Tap Javascript API
* #param {*} resolve
*/
const loadOneTapJsAPI = (resolve) => {
window.onload = () => {
google.accounts.id.initialize({
client_id: "My client Id",
callback: data => resolve(data)
});
google.accounts.id.prompt();
}
}
export const loadOneTap = async() => {
return new Promise( (resolve, reject) => {
loadOneTapClientLibrary();
loadOneTapJsAPI(resolve);
})
}
After page loads i am calling loadOneTap();
To avoid One Tap UI prompting too frequently to end users, if users close the UI by the 'X' button, the One Tap will be disabled for a while. This is the so-called "Exponental Cool Down" feature. More detail at: https://developers.google.com/identity/one-tap/web/guides/features#exponential_cool_down
I believe you triggered this feature during development. To avoid this, use Chrome incognito mode (and restart the browser when necessary).
As noted by Guibin this is the OneTap exponential cool down feature, it can be easily triggered during development when testing auth flow, but also legitimately when the end user clicks the close icon by mistake. On sites where Google login is optional this might seem pragmatic (i.e. the user genuinely wants to dismiss the popup prompt in favor of alternative login methods), however on a site where Google is the sole login identity provider and you are using the Javascript API instead of HTML api then this can manifest as broken functionality - i.e. no login prompt - and you want to avoid telling your users to use incognito or clear cache/cookies at all costs..
You can potentially handle this with some fallback logic..
window.google.accounts.id.prompt((notification) => {
if(notification.isNotDisplayed() || !notification.isDisplayed()) {
// #ts-ignore
const buttonDiv = window.document.createElement("div")
buttonDiv.setAttribute("id", "googleLoginBtn")
document.getElementsByTagName('body')[0].appendChild(buttonDiv);
// #ts-ignore
window.google.accounts.id.renderButton(
document.getElementById("googleLoginBtn"),
{ theme: "outline", size: "large" } // customization attributes
);
}
This renders a button to login that isn't subject the one-tap cool down feature. We're early days into playing with this so there may be other invariants with regards to state you need to consider (e.g. can isNotDisplayed return true when already logged in) - we already observed some oddities where isDisplayed and isNotDisplayed can both be false on the same invocation of the callback.
Extra note: I recall reading the user can disable all one tap features too, so if you're using the javascript API instead HTML api you will need the fallback to SignIn with Google button.
I'm using CefSharp (47) to render a webpage from a host that I have no control over, and I want to make some additional CSS tweaks to those provided by the host.
Reading up on various topics across GitHub (https://github.com/cefsharp/CefSharp/blob/cefsharp/47/CefSharp.Example/CefSharpSchemeHandlerFactory.cs), and here (CefSharp custom SchemeHandler), I wrote a custom scheme handler accordingly:
public class CustomSchemeHandlerFactory : ISchemeHandlerFactory
{
public const string SchemeName = "custom";
public IResourceHandler Create(IBrowser browser, IFrame frame, string schemeName, IRequest request)
{
Console.WriteLine(request.Url);
if (schemeName.ToLower() == SchemeName.ToLower())
{
// Do some stuff
}
return null;
}
}
I attempt to bind it in my application in the following manner:
CefSettings settings = new CefSettings();
settings.CachePath = browserCachePath;
settings.RegisterScheme(new CefCustomScheme()
{
SchemeName = CustomSchemeHandlerFactory.SchemeName,
SchemeHandlerFactory = new CustomSchemeHandlerFactory()
});
Cef.Initialize(settings);
The application then browses to the appropriate website, and uses the 'LoadingStateChanged' event to then fire off some JavaScript to inject the CSS file I want to load:
string linkText = "<link rel=\u0022stylesheet\u0022 type=\u0022text/css\u0022 href=\u0022custom://custom.css\u0022>";
var jsFunctionText = string.Format("(function() {{ $('head').append('{0}'); return true;}}) ();", linkText);
var injectionTask = await _myBrowser.GetMainFrame().EvaluateScriptAsync(jsFunctionText, null);
...which succeeds.
But my custom resource handler 'Create' event is never fired.
I can only presume that the handler isn't being registered properly, so I'd appreciate any advice/help in getting this working properly!
Thanks!
I am implementing functionality to notify the user of long running job completions using SignalR in an AngularJS application.I have created groups of user based on their name,so for each user a group of his name and different connectionids which he has opened up will be created and he would be notified by his group. I want to notify the user on two pages i.e. landing Page and Job Run Page as even if the user is on landing page and job run completes he should be notified of it.
For the same reason i am creating group by his name on both the pages,so that if he is on any page he would be nofied through the group.
On landing page controller js file i have written code to add the user in group as follow...
$rootScope.signalRHub = $.connection.signalRHub;
$rootScope.hubStart = null;
$rootScope.startHub = function () {
if ($rootScope.hubStart == null)
{
$rootScope.hubStart = $.connection.hub.start();
}
return $rootScope.hubStart;
}
$scope.$on('$locationChangeStart', function (event) {
if ($rootScope.userName != "") {
$rootScope.signalRHub.server.leaveGroup($rootScope.userName);
}
});
// Start the connection
$rootScope.startHub().done(function () {
$rootScope.signalRHub.server.joinGroup($rootScope.userName);
});
on Job Run controller js file i have written following code....
$rootScope.signalRHub.client.showNotification = function (message) {
notify('Your notification message');//notify is the angular js directive injected in this controller which runs fine
};
$scope.$on('$locationChangeStart', function (event) {
$rootScope.signalRHub.server.leaveGroup($rootScope.studyid);
});
// Start the connection
$rootScope.startHub().done(function () {
$rootScope.signalRHub.server.joinGroup($rootScope.userName
});
My Hub File.....
[EnableCors(origins: "*", headers: "*", methods: "*")]
public class SignalRHub : Hub
{
public Task JoinGroup(string groupName)
{
return Groups.Add(Context.ConnectionId, groupName);
}
public Task LeaveGroup(string groupName)
{
return Groups.Remove(Context.ConnectionId, groupName);
}
public void ShowNotification(string jobRunDetailId, string userName)
{
if (!string.IsNullOrEmpty(userName))
{
var context = GlobalHost.ConnectionManager.GetHubContext<SignalRHub>();
context.Clients.Group(userName).showNotification(jobRunDetailId);
}
}
}
The issue is when i run the application the group add functionality for both pages works fine.but when i call "showNotification" from Hub it doesn't show any message.
But strange thing is if i comment the "$rootScope.startHub().done...." function on landing page then the jobrun page notify functionality works fine.I am not sure if writing "$rootScope.startHub().done()..." on two places is creating this problem.please help.
You need to wire up all callbacks before calling start. If you turn client side logging on, it'll tell you what hubs you are subscribed to.
Aside:
[EnableCors] is a webapi specific attribute that does not work in SignalR.
I am currently working on a game, which will consist out of an API-based backend, along with a web frontend (which is a single page app, in AngularJS) and on several mobile devices (using Cordova). I am planning on serving the SPA over the main domain name, along with a CDN. The SPA (and homepage) will all be static HTML/Javascript/CSS files, so the only part which is dynamic is the api. The domain name for the "main server" hosting the static sites will be in the style of example.com, the one for the api will be api.example.com
I am wondering how I can integrate Paypal into this scenario though. The internet doesn't seem to offer much advice on how to integrate it into S.P.A's like this...or my google-fu could be off. Thanks for the replies.
Below is how I am handling the situation,
I have a button to say pay with paypal and onClick I open a new window -> window.open("/paypalCreate", width = "20px", height = "20px");
and I capture this get request "/paypalCreate" in my node.js server and call create method which looks liek below
exports.create = function (req, res) {
//Payment object
var payment = {
//fill details from DB
};
//Passing the payment over to PayPal
paypal.payment.create(payment, function (error, payment) {
if (error) {
console.log(error);
} else {
if (payment.payer.payment_method === 'paypal') {
req.session.paymentId = payment.id;
var redirectUrl;
for (var i = 0; i < payment.links.length; i++) {
var link = payment.links[i];
if (link.method === 'REDIRECT') {
redirectUrl = link.href;
}
}
res.redirect(redirectUrl);
}
}
});
};
This redirects user to paypal and once user confirms or cancels payment, the redirect urls are called. And in the success redirect url I capture the payment details into the databse and render a html in this opened window with the confirmation.
exports.execute = function (req, res) {
var paymentId = req.session.paymentId;
var payerId = req.param('PayerID');
// 1. if this is executed, then that means the payment was successful, now store the paymentId, payerId and token into the database
// 2. At the close of the popup window open a confirmation for the reserved listing
var details = {"payer_id": payerId};
paypal.payment.execute(paymentId, details, function (error, payment) {
if (error) {
console.log(error);
} else {
//res.send("Hell yeah!");
res.render('paypalSuccess', {payerId: payerId, paymentId: paymentId});
}
});
};
Once the user closes the opened window in which paypal was being handled the orginal SPA window will be refreshed and thus getting the payment details from the DB and here you can handle the SPA in whatever way you want.
I know that this is a dirty hack, but like you I couldnt find a better way. Please let me know if this works for you or if you have a found a better way to do tihs.
cheers,

I'm looking for a way with the CakePHP-Facebook-Plugin log users out of my app, but not log them out of their own facebook.
If I call my apps logout() function no matter what I do I just keep getting logged back in via facebook. If I use the plugins facebook helper in the view to generate a logout button ($this->Facebook->logout()), it definetly logs the user out of my app...but it also logs them out of their own facebook which is kinda ridiculous.
So how do I work around this to log users out of my app, and but leave them logged into facebook.
To have them "logout" of your app (meaning the next time they try to use the app, they're going to be asked to authenticate your app again), then send an HTTP DELETE command to me/permissions using their user access token.
I know this is an old question, but I figured this one out just now, trying to figure this same thing out. Basically, although in the demos with webtechnick's examples, he puts "Facebook.Connect" in the AppController, but, if you want the selective logout piece, the Best place to put it is within the actual controllers that you want to use it in or put it in AppController and pass noAuth=> true into it. Either way, whichever way you choose, you set up one controller (facebook_controller.php?) to handle the logins, and set its component with the noauth set to false (which is default). That way, you have total control over whether or not the user is logged back into the site, and you can ACTUALLY log them out (with the regular redirect($this->Auth->logout());
Let me give you an idea:
app_controller.php
class AppController extends Controller {
var $components = array('Auth', 'Acl', 'Session');
//or if you want access to "$this->Connect" universally:
// array('Auth', 'Facebook.Connect' =>
// array('noauth'=>'true', 'Acl', 'Session');
}
users_controller.php:
class UsersController extends AppController{
var $helpers = array('Facebook.Facebook');
//an example of the users controller, enabling connect, but
// not authorizing the user (because logout() used by Auth is here)
var $components = array('Email', 'Session', 'Facebook.Connect' => array('createUser'=>false, 'noauth'=>true));
//login() doesnt need to be shown and can be left alone
function logout(){
if ($this->Connect->FB->getUser() == 0){
$this->redirect($this->Auth->logout());
}else{
//ditch FB data for safety
$this->Connect->FB->destroysession();
//hope its all gone with this
session_destroy();
//logout and redirect to the screen that you usually do.
$this->redirect($this->Auth->logout());
}
}
}
your "facebook_controller.php":
class FacebookaController extends AppController {
...
// i dont personally like to have his piece create my user so:
var $components = array('Facebook.Connect' => array('createUser'=>false));
...
function login(){
//just need this stub function for later
$this->autoRender = false;
}
//you also need this for deauths or they will still be able to get into the site after deauth (against policy or whatever)
function deauthorize(){
//get user id from facebook API
$uid = $this->Connect->FB->getUser();
$record = $this->User->findByFacebookId($uid);
$this->User->delete($record['id'], FALSE);
}
}
now your users/login.ctp file:
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'your app id', // App ID
channelUrl : '//'+window.location.hostname+'/facebook/channel', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Additional initialization code here
FB.Event.subscribe('auth.statusChange', function(response){
if (response.status == "connected"){
alert('redirecting you to auto facebook login');
//here is out default place for login
window.location.href = "http://"+window.location.hostname + "/facebook/login";
}
});
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>
<?php e($this->Facebook->login(array('registration-url'=>'http://www.yoursite.com/facebook/signup'))); ?>
And that should be pretty much it. I hope this helps someone reading this who still needs the help.
You may want to take a look at $this->Facebook->disconnect();
It does exactly what you want.

Have you tried killing the PHP session?
// this would destroy the session variables
session_destroy();
