Quickblox iOS - Logs in Fine. Can't get Facebook popup to appear? - ios

I'm working my way through the relevant Quickblox modules starting with users. I can authenticate an application and register a new account and login.
I tried to login with a Facebook account using
[QBRequest logInWithSocialProvider:#"facebook" scope:#[] successBlock:[self successBlock] errorBlock:[self errorBlock]];
but nothing happens. When I try it with the sample code, I get a popup dialog. The API is so well hidden, I can't troubleshoot the popup. What am I missing?
The console output:
Request URL:https://api.quickblox.com/login.json
Request method: POST
Request parameters:{
provider = facebook;
}
Request headers: {
"Content-Type" = "application/json";
"QB-SDK" = "iOS 2.0.9";

Well, now I feel silly. I kept working on the app and then I discovered that the dialog screen actually popped UNDER the top viewController.

FuelPHP Cache-control and Expied

I dont know how to where i should start from.
So, pleaes forgive me if I'm asking wrong question.
I have an iOS app. The app request to an API of CentOS server which using FuelPHP to get list of data. Also, we are using CDN to cache the data (Azure -Verizon)
When I get respond header, I saw that :
Access-Control-Allow-Headers" = ": X-Requested-With";
"Access-Control-Allow-Methods" = ": post, get, origins";
"Access-Control-Allow-Origin" = ": *";
"Cache-Control" = "no-cache, must-revalidate";
Connection = close;

Pragma = "no-cache";
Server = "Apache/2.2.15 (CentOS)";
"Transfer-Encoding" = Identity;
"X-Powered-By" = "PHP/5.5.32
What should I do to make Cache-Control become max-age=xxx?
what I want is to cache the data via CDN of window Aruze Verizon.
Please help, If my question is not clear, please guide me, i will provide mor information.

NSURLConnection response's expectedContentLength -1

*
Note: There are several links on this topic but it didn't work for me,
So I have to post the new one here.
*
Basically I'm trying to show the UIProgressView to show the data being fetched from the web service. Now problem is that I'm getting the expectedContentLength for almost all the service that I call from my application and the response headers contains the Content-Length. But for one of the web service's response it doesn't return the expectedContentLength, instead always returns -1.
Following are the response headers that I get for two different web service response :
- Response header for which I get the content length.(Data from service is not huge)
{
Connection = "Keep-Alive";
"Content-Length" = 2689;
"Content-Type" = "application/json";
Date = "Tue, 23 Jun 2015 08:19:04 GMT";
"Keep-Alive" = "timeout=5, max=98";
Server = "Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15";
"X-Powered-By" = "PHP/5.5.15";
}
- Response header for which I don't get the content length. (Response contains the huge data, no files to be downloaded just JSON data)
{
Connection = "Keep-Alive";
"Content-Type" = "application/json";
Date = "Tue, 23 Jun 2015 08:12:34 GMT";
"Keep-Alive" = "timeout=5, max=97";
Server = "Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15";
"Transfer-Encoding" = Identity;
"X-Powered-By" = "PHP/5.5.15";
}
The Above service response contains huge data. When tested the response on Advanced rest client chrome's extension It gives following response header with "Transfer-Encoding" = chunked;.
Date: Tue, 23 Jun 2015 12:01:20 GMT
Server: Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15
X-Powered-By: PHP/5.5.15
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/json
I used following links, but none of them helped me:
Link1 , Link2 , Link3
Please help me.
Thanks!
Updated code:
After setting the Content-Lenth header on server side I got the valid response with Content-Length header on Advanced rest client chrome's extension.
Date: Wed, 24 Jun 2015 05:25:48 GMT
Server: Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15
X-Powered-By: PHP/5.5.15
Content-Length: 1272347
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: application/json
But on client side (i.e in iOS Application) I still didn't get the Content-Lenth header so that I can get the expectedContentLength value.
I still get "Transfer-Encoding" = Identity; in the response header on my side.
I have also set the Accept-Encoding header in the request as follows :
[req setValue:#"identity;q=0" forHTTPHeaderField:#"Accept-Encoding"];
Is there anything more to be done on either side(server/client).
I don't know how one gets the content length added at the server side - I had problems with this before, and in one case I had a similar situation as yours - the content length was visible by dumping all headers, but iOS didn't hand it to me in the delegate method. The standard way to get it is via:
- (void)connection:(NSURLConnection *)conn didReceiveResponse:(NSURLResponse *)response
{
...
NSUInteger responseLength = response.expectedContentLength == NSURLResponseUnknownLength ? 1024 : (NSUInteger)response.expectedContentLength;
I actually entered a bug on this: rdar://15605995 "HTTP Get response is 200 but response.expectedContentLength = -1 even when a Content-Length is found in the headers"

"X-Frame-Options" = SAMEORIGIN;
"X-Powered-By" = <Company>;
"X-<Company>-Server" = "<private>";
"X-XSS-Protection" = "1; mode=block";
}
for this code:
if(response.expectedContentLength == NSURLResponseUnknownLength) {
id len = httpResponse.allHeaderFields[#"Content-Length"];
if(len) {
responseLength = [len integerValue];
}
NSLog(#"YIKES:LEN=%# %#", len, httpResponse.allHeaderFields);
}
This is going to be really hard for me to special case. I'm accessing an internal company data base, I have to use name/password first, then get a code to my phone (which I later enter) to get in. Is there other info I could grab to help you? How can it be that the content length is clearly there in the header, but you don't see it and return it to me?
Apple closed my bug, saying "Works as Expected". Really!?!?!?!?!?!?!
[I don't know if NSURLSession fixed it or not.]
EDIT: I should have added that in the past, other sites I connected to DID result in a properly set 'expectedContentLength'.

Instagram API, AFNetworking 2.0 iOS client 400 error

I haven't changed anything in my app and my code seems to generate the proper URL with access token attached, but I am getting a 400 error bad request for the past day. It doesn't seem as if Instagram has changed the endpoint. Can someone help me decipher the error log to see if there is any usable info here to help me debug? Access Token x'd out.

MGTwitterEngine statusesReceived not firing

A few time ago I've developed an iOS app with MGTwitterEngine and XML parsing option.
Since Twitter updated the API to 1.1, seems to be that all messages must be called with JSON format.
After a long nightmare to integrate YAJL library with MGTwitterEngine, my program makes a Succeeded Request but the statusesReceived delegate method is not fired.
I've checked if the delegated is properly assigned, and everything is correct. After launch the HTTP request I get the response OK but not any message.
Here an example of the call I made:
INFO -> Twitter URL: https://api.twitter.com/1.1/statuses/user_timeline.json?since_id=1&screen_name=CFarmaceutico&count=50
And here the response:
MGTwitterEngine: (200) [no error]:

"Cache-Control" = "no-cache, no-store, must-revalidate, pre-check=0, post-check=0";
"Content-Encoding" = gzip;

But the statusesReceived method is not called anymore.
Any idea?
Thanks.
no idea - but MGTwitterEngine does not support API 1.1, and when API 1.1 was released, we tried hard to get MGTwitterEngine working - and failed. Eventually we converted our app to FHSTwitterEngine - and it works fine since then. It was relatively straightforward process so I would strongly recommend you to do the same. It will take you less time than fixing bugs in MGTwitterEngine.

iOS, RESTKit and oAuth - simple sample not working

I am writing a simple application on iOS and I am trying to consume a RESTFull webservice
To have some tips and get some knowledge I first start with twitter without using ios integrated libs, but I always get stocked on Auth.
Any working sample or link will be appreciated, as reminder twitter is not my final goal
For instance this is one of my code, based on RestKit and AFOAuth1Client :
NSURL *url = [NSURL URLWithString:#"https://api.twitter.com"];
AFOAuth1Client * twitterClient = [[AFOAuth1Client alloc] initWithBaseURL:url key:kCLIENTID secret:kCLIENTSECRET];
[twitterClient authorizeUsingOAuthWithRequestTokenPath:#"oauth/request_token"
userAuthorizationPath:#"oauth/authorize"
callbackURL:[NSURL URLWithString:#"af-twitter://success"]
accessTokenPath:#"oauth/access_token"
accessMethod:#"POST"
scope:#""
success:^(AFOAuth1Token *token, id responseObject) {
}
failure:^(NSError *error) {
}];
as you can see it does not work :

"401 Unauthorized" indicates that your credentials are incorrect. So check your API keys.
try this:

} failure:^(NSError *error) {

}];
Note the line scope:nil, for some reason it doesn't work with empty string.
Among other things, check your application settings in twitter. I'm not sure if this is the case, but I enabled Allow this application to be used to Sign in with Twitter and set Callback URL to some random valid url
