I want to make a Browser like Safari with UIWebView,
which can show the loading progress of the web page.
And I saw an app "Downloads Lite - Downloader & Download Manager" selling in app store
(http://itunes.apple.com/app/id349275540?&mt=8) that can do this.
It also can customize User Agent of request,
even get "content type" of Response Header to decide whether it's needed to be downloaded.
But it seems that it's impossible to make it happen with the public APIs of UIWebView,
so I'm wondering how he did that.
Could you give me some tips about this?
There is no need for private API to do things like this.
You take a progress indicator for example. By using asynchronous NSURLConnection you can get the size of the expected size of the content you want to download :
-(void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse*)response
{
[response expectedContentLength];
}
Then you simply compare with the amount of data you downloaded so far.
Customizing User Agents can be done with CFNetwork framework.
have a look at this app/blog: icab.de
General approach is to make subclass of NSProtocol and catch all http/https request, that gives you all you want.

I've been trying to get OAuth 2.0 to work correctly. I have managed to make the url that that will do the "deny/allow" for my app by opening a webpage with just
Application.OpenUrl(uri.ToString());
The problem is that I have no idea how to get the redirect and the auth token from the page if the user hits allow. When you hit allow, right now nothing happens it just sits on the page. Checking Networking in chrome debug does have the redirect and token there but it never actually sends it..
I was recommended to use RestSharp but I again have no idea how to use it with Unity as there are lot of resources for Android/iOS PC etc. but I can't get any of them to work for this Unity project...
var client = new RestClient("https://www.fitbit.com/oauth2/authorize?response_type=code&client_id=*clientID*&redirect_uri=http%3A%2F%2FfitRPGcallback&scope=activity%20profile%20sleep%20social");
Debug.Log("client made");
var request = new RestRequest(Method.POST);
request.Resource = ("profile%20sleep%20social");
client.ExecuteAsync(request, response => { Debug.Log("response is : " + response.Content);});
Application.OpenURL(client.BaseUrl.ToString());
In the URL I do have the correct clientID in there as well just not sure what I can and can't show for security reasons etc.
Biggest problem is just having no idea how to get the return value from the webpage after the user hits allow/deny...
Any insights would be super super appreciated cause I just want to start making the actual game but there's not as much point if I can't get this data...
So, I'm posting on a few other applicable questions as well since I have finally figured out my answer.
Unfortunately I'm not using REST so that part is still up in the air BUT I did get it to work with just Fitbit, Unity and a Webview plugin (you will need a webview OR a way to get the initial code back from your first OAuth2 call)
You can find steps here.

EDIT:
So I had to change how I did it because Fitbit changed their ToS where we are no longer allowed to use Webview based Authenticators (which is what I was using in the above blogpost.)
Give this next post a look for how to make an Android Plugin that will grab the Accesstoken from Fitbit's OAuth. This is a FREE way to do it since you make it yourself and it's ezmode :)

Hi Google Drive Staff,
I have tried to stream video files from Google Drive(Without Downloading). But I gets alerts that Sign In. I have went thoroughly with Dr. Edit sample App but i did not found any solution. I tried with downloadUrl , embedLink, webContentLink, alternateLink. All gives message to sign In. When i tried with exportsLinks i get a Null Message. What is the problem Here. If U have any suggestion Please Let me Know...
I have tried with Google Drive for iOS in iPod, there we can stream Video without Downloading.
Please suggest me to resolve this issue
Thanks in Advance...
I could solve it just by appending the access_token to the download url
audiofile.strPath=[NSString stringWithFormat#"%#&access_token=%#",downloadUrl,accessToken];
pass the strPath to your avplayer object to play music.
I did not try the video part. but i think a similar approach should work.
you can fetch the access token from the GTMOAuth2Authentication object
Note that you might need to refresh it if its expires.
Hope this helps you.
Regards
Nitesh
I think it depends what you mean by "stream". Last time I looked, the download links all had a content disposition: attachment header, which instructs the browser to download rather than render the content.
If you have your own client fetching the url, you can choose to ignore that header and do what you like with the content as it is fetched. imho, it would be nice if the client could add a parameter to the url to indicate to the Google servers that it wants the content to be rendered v. downloaded, but hey ho.
You need to authorize all requests to downloadLinks with an Authorization header. Read more about the authorization and learn how to retrieve your users an access token on https://developers.google.com/drive/about-auth
Starting with Zend and I´d like to know what is the simplest way of sending POST data to another page, not by forms, but by some link in my view instead. Thanks :)
You can't send POST data through a link. At least not through a normal link. Link can only carry GET data.
If you need to send POST over a link it's most certainly a design flaw.
If you're 100% sure, that you need it, you can do that using jQuery and onclick event. It`s not possible to do it without javascript. Other option would be to send it using form with hidden fields with single submit button visible - that would even work without javascript.
Normal hyperlinks in HTML are sent with GET requests and are not supposed to change the state of the resource being accessed. This is known as being idempotent. You can repeat the request over and over, and the result of each succeeding request to the same URL is the same as the first one.
POST requests don't have this restriction and are intended for when the user needs to change something (such as creating a new resource.)
It's not possible to send a POST request via a normal HTML link. And even if you find a way, it breaks an almost universal expectation that web users have. What are you trying to accomplish? Maybe there's a better way.
But to answer your question, you could use something like jQuery to capture the "click" event and make it do a POST request:
$('.my-link').click(function() {
var url = $(this).attr('href');
var data = {};
$.post(url, data, function() {
window.alert('success!');
});
return false;
});
If your URL has any query parameters, i.e. "?foo=bar&baz=bum", then you'd probably need to strip them off of the URL and pass them as a second parameter to the $.post() function. This is left as an exercise for the reader. ;-)
I am using ShareKit for iphone to share some text in facebook. Can any one tell me which delegate is called after publishing the text successfully. I need this to inform the user that his action was successful.
The shareDelegate property in SHKSharer isn't the easiest to get to and change, but there are notifications sent from the delegate methods of SHKSharer, one for each of the methods: SHKSendDidStartNotification, SHKSendDidFinish, SHKSendDidCancel, SHKSendDidFailWithError. Observing these notifications turns out to be a simple way of listening for the outcome of sharing.
See shareDelegate property of SHKSharer . All the concrete sharers (e.g. SHKFacebook) extend this base class.
Having said that, I'm not sure where you set a class to be the delegate using ShareKit's public API (so I'm not claiming this to be a complete answer).
There are a bunch of tutorials online about how to use xmlparsers or what not to bring an entire twitter feed into a UITableView. Thats not what I need. I only want ONE tweet. The most recent twitter update.
So, would some of you geniuses please show me in detail how to get my last (most recent) TWEET into an NSString in my iPhone app?
In short: exactly the same as all those tutorials that you've read except you pass the count parameter to the statuses/user_timeline REST method.
Ohh, this is complicated, not so easy, I show you the steps:
Make the request to the api (synchronous or asynchonous)
Handle the Authentication Challenge for authenticated request
Get the data, call the parse method of the parser
Handle the delegation methods of the nsxmlparser
Manually handle the DidStartElement, DidFoundCharacters, DidEndElement to get the first status you want, assign the string value to a variable when it founds the characters.
That's all you need to do ;)
Good luck.
