I can't find easy answers on the web. I know that Social.framework is great for making things less complicated and less buggy. However I tried to implement like and failed - I don't think it is possible using only Social.framework. Now I'm trying to get some posts image and add a comment to it, it's also complicated, I'm not sure if possible. It seems all more complicated stuff you used to do via opengraph isn't possible with Social.framework.
Maybe there is a way to mix Social.framework with FacebookSDK and log user via the first framework and get object via 2nd with opengraph?
Can anyone write if these actions are possible? Or how to know what is possible/impossible with Social.framework? I consider mainly Facebook.
-- edit --
An example would be:
NSURL *likeUrl = [NSURL URLWithString:#"https://graph.facebook.com/me/og.likes"];
NSURL *objectUrl = [NSURL URLWithString:#"object_with_tags_to_like"];
NSDictionary *parameters = #{ACFacebookAppIdKey: #"111",
#"object": objectUrl};
SLRequest *facebookRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodPOST
URL:likeUrl
parameters:parameters];
facebookRequest.account = facebookAccount;
[facebookRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
// set a breakpoint here, we're getting in resp:
// "Www-Authenticate" = "OAuth \"Facebook Platform\" \"invalid_request\" \
// "The action you're trying to publish is invalid because it does not specify any reference objects.
// At least one of the following properties must be specified: object.\"";
}];
Here we can see that passing object isn't easy. With FacebookSDK you'd simply:
NSMutableDictionary<FBGraphObject> *action = [FBGraphObject graphObject];
action[#"object"] = urlAddress;
[FBRequestConnection startForPostWithGraphPath:#"me/og.likes"
graphObject:action
completionHandler:nil];
But here you can't create FBGraphObject. What to use instead?
Honestly the Facebook SDK is quit powerful and simple to use. It allows you much more functionality in terms of Liking and Commenting so I would recommend you move towards that. The SocialFramework is limited, it is mainly used for sending a quick post (using their template, -> no customization) and quick login.
I have successfully done all of what you are asking for using solely the Facebook SDK.

I've tried checking on stackoverflow and on the api docs, but couldn't find any info pertaining to this particular question.
What I'm trying to do is getting the public folder contents of a particular dropbox account (like the /metadata function of the api), without the need to authorize/link to dropbox.
I know "/metadata/link" allows you to get metadata of a particular link without user authorization, but I couldn't find a way to get regular metadata and file listing...
Actually it doesn't even need to be a public folder (as I've read recently that dropbox discourages developers regarding relying on public folders for apps), it can just as well be a regular folder through its shared link or anything of the kind...
I'm using api v1 (but can consider changing to v2 if this is impossible with v1), although I'm not even sure if this is at all possible.
Thank you!
For future reference, if anyone needs this as well, here's how I did it:
NSString *parameters = [NSString stringWithFormat:#"?link=%#&client_id=%#&client_secret=%#",fileUrl, appKey, appSecret];
NSString *sharedPath = [NSString stringWithFormat:#"%#/%#",#"https://api.dropbox.com/1/metadata/link", parameters];
NSURL *url = [NSURL URLWithString:sharedPath];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
timeoutInterval:10];
theRequest.timeoutInterval = 5.0;
theRequest.HTTPMethod = #"POST";
NSData * resData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:nil error:nil];
Use NSJSONSerialization to parse resData and refer to the api documentation for json fields, and that's it.
For the sake of simplicity showing it here I used synchronous request, but it can just as easily be done with asynchronous connection delegates.
I am looking for a way to retrieve the profile information of a LinkedIn user by making a post request, I have read these two LinkedIn pages but it doesn't seem to explain much, or I couldn't understand much of it:
REST API LinkedIn
basic profile informations
I have seen these example on stackoverflow but I didn't understood to much:
http://api.linkedin.com/v1/people/~:(id,first-name,last-name,maiden-name,email-address,formatted-name,phonetic-last-name,location:(country:(code)),industry,distance,current-status,current-share,network,skills,phone-numbers,date-of-birth,main-address,positions:(title),educations:(school-name,field-of-study,start-date,end-date,degree,activities))
I am only interested to retrieve the skills section the one that on the website appears as so:
There's a fantastic library for LinkedIn-iOS integration by Kirsten Jones, you can use that to make calls to the LinkedIn API. You need an access token to make calls.
https://github.com/PrincessPolymath/LinkedIn-OAuth-Sample-Client
Make calls like this:
NSURL *url = [NSURL URLWithString:#"http://api.linkedin.com/v1/people/~:(id,first-name,last-name,maiden-name,formatted-name,phonetic-last-name,location:(country:(code)),industry,distance,current-status,current-share,network,skills,phone-numbers,date-of-birth,main-address,positions:(title),educations:(school-name,field-of-study,start-date,end-date,degree,activities))"]];
OAMutableURLRequest *request =
[[OAMutableURLRequest alloc] initWithURL:url
consumer:oAuthLoginView.consumer
token:oAuthLoginView.accessToken
callback:nil
signatureProvider:nil];
[request setValue:#"json" forHTTPHeaderField:#"x-li-format"];
OADataFetcher *fetcher = [[OADataFetcher alloc] init];
[fetcher fetchDataWithRequest:request
delegate:self
didFinishSelector:#selector(profileApiCallResult:didFinish:)
didFailSelector:#selector(profileApiCallResult:didFail:)];
- (void)profileApiCallResult:(OAServiceTicket *)ticket didFinish:(NSData *)data
{
NSString *responseBody = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
NSDictionary *profile = [responseBody objectFromJSONString];
if ( profile )
{
name.text = [[NSString alloc] initWithFormat:#"%# %#",
[profile objectForKey:#"firstName"], [profile objectForKey:#"lastName"]];
headline.text = [profile objectForKey:#"headline"];
.....and get skills and other user details
}
}
Use tool:https://apigee.com/console/linkedin
API to get the list of Skills:
https://api.linkedin.com/v1/people/~:(id,num-connections,skills)?format=json
I tried it in the Console tool and able to fetch the skills for my profile. I think the individual skill ID with above request should help you to get further information. Try it out.
If anyone is reading this answer, the LinkedIn API has limited access as of May 2015. You will need to apply to their Apply with LinkedIn program to access full profile fields including skills.
https://developer.linkedin.com/docs/fields
I have fair amount of experience working with the linkedIn API. It's been a little while, but hopefully this will set you on the right track.
To get profile information from a linked in user who is one of your connections you need a format like follows:
NSString *theRequest = [NSString stringWithFormat:#"https://api.linkedin.com/v1/people/id=abc123:(first-name,last-name,picture-url,location:(name))?oauth2_access_token=%#&format=json", accessToken];
This request will return the first name, last name, profile picture url, and location of the user with the id specified.
You can see a list of field types you can request by checking out linkedIn's documentation on their profile field descriptions here:
https://developer.linkedin.com/docs/fields
If you're wondering how to get the id of the user whose profile information you want request in the first place, you can make request for some basic info (including ids) of all your connections like this:
NSString *basicConnectionInfo = [NSString stringWithFormat:#"https://api.linkedin.com/v1/people/~/connections:(id,first-name,last-name)?oauth2_access_token=%#&format=json", accessToken];
This request will give you the id, first name, and last name of all of your connections. After you've gotten the id of the person you want, you can make a request using the user's id (as shown in the first example).
Now for the slightly unfortunately news... If you followed the link provided above, you'll notice that the skills field is part of the "Member profile fields available to Apply with LinkedIn developers". I'm assuming you'll have to follow this link they provided: https://developer.linkedin.com/docs/apply-with-linkedin in order to access the skills member profile field.
I have not applied with LinkedIn. So, I haven't tested a call to the skills field. But, I'm guessing it'll be similar to the examples I've shown you. Hope this helps!
I'm interested in integrating the Imgur API into my app, and it states that in order to get image information (basically the extent of what I need right now) I just need to register my app, no need to log in with user information or anything.
Great, I'm using AFOAuth2Client (specifically this pull request so it works with AFNetworking 2.0). I have my client key and client secret, but I can't seem to figure out how to get to an image.
I try the following code (personal API details removed):
AFOAuth2Client *oauthClient = [AFOAuth2Client clientWithBaseURL:[NSURL URLWithString:#"https://api.imgur.com/"] clientID:#"---" secret:#"---"];
[oauthClient authenticateUsingOAuthWithURLString:#"https://api.imgur.com/oauth2/authorize" parameters:nil success:^(AFOAuthCredential *credential) {
NSLog(#"Yes");
} failure:^(NSError *error) {
NSLog(#"No");
}];
But I always get No outputted. How do I properly authenticate so I can then make calls to the API to get information about an image? (As detailed here.)
As I've been told I don't need OAuth period, I tried the following with AFNetworking 2.0 (to no avail):
AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager POST:#"https://api.imgur.com/3/image/1Nf1quS" parameters:#{#"Authorization": #"Client-ID myactualclientidisremoved"} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"success");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"failure");
}];
First, the example is using Imgur API v2 which is old and unsupported. You should be using API v3.
Also note that:
For public read-only and anonymous resources, such as getting image info, looking up user comments, etc. all you need to do is send an authorization header with your client_id in your requests.
from docs at https://api.imgur.com/oauth2 -- so you don't really need OAuth for what you're doing.
There is some example Imgur API code that might help you, listed at https://api.imgur.com/ -- the Android example might be more relevant to you, since it uses Java, but unsurprisingly it comes with all the overhead of an Android project, compared with a plain Java application.
I'm using the iOS SDK with the native dialog to try to post an object and action.
When I call presentShareDialogWithOpenGraphAction, the Facebook app opens, briefly shows the dialog with my post in it, and then returns to my app with the error:
Could not generate preview text
My code looks like this:
NSDictionary* object = #{
#"fbsdk:create_object": #YES,
#"type": #"appsterbator.app_idea",
#"title": #"test",
#"url": #"http://test.com",
};
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:object
forKey:#"app_idea"];
[FBDialogs presentShareDialogWithOpenGraphAction:action actionType:#"app_idea.create"
previewPropertyName:#"app_idea"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
NSLog(#"%#", error);
}];
Also, is it possible post an Open Graph object that doesn't actually have a URL?
I had the same symptoms, but a different fix. Facebook SDK 3.5.* since the Share Dialog came out of beta.
I had a custom Object Graph story: Solve -> Puzzle. This was my first time working with OG, so this might seem obvious to someone more familiar with it, but it stalled me for long enough that I wanted to share.
I ran through the Share Dialog examples on the developer site, but the Open Graph related sharing would not work via simple copy paste. I figured because the OG objects were tied to the App ID and URL host etc. I setup my web host so that I could serve OG data for my objects, and configured my app to allow that host etc..
So I set about adapting the sample code to use the parameters present in the "opengraph / stories -> Get Code" popover. Setting the platform to iOS SDK, I got the following for Create Action:
NSMutableDictionary<FBGraphObject> *action = [FBGraphObject graphObject];
action[#"puzzle"] = #"http://samples.ogp.me/463417983744195";
[FBRequestConnection startForPostWithGraphPath:#"me/shapeshuffle:solve"
graphObject:action
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
// handle the result
}];
I swapped my story and app specific values into the sample code, leading to the the error and symptoms described in the question.
I spent longer than I care to admit fiddling with the server hosting my OG object, FB App settings, different ways of popping the share dialog etc.
The root of the problem was that on popping the dialog, FB was unable to match the action and object with the configuration in my app - hence the slightly vague error code relating to generating the preview text. FB wasn't finding the action because "me/shapeshuffle:solve" (the action string in the "Get Code" tool) doesn't resolve. If I understood all the different options available to me in the Get Code tool, I might have avoided this, but remember, all I wanted was to pop a share dialog. Seemed simple.
I worked with the Graph API explorer via this useful tutorial, and wound up with the following mapping from the strings I got from the FB tool to what actually worked:
Action:
me/shapeshuffle:solve => shapeshuffle:solve
Lots of pain for 3 little characters. Here is what my finished code looks like:
NSString *objectUrl = [NSString stringWithFormat:#"%#puzzleId=%d", #"http://myhost.com/puzzle/object?", puzzleId];
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:objectUrl forKey:#"puzzle"];
[action setObject:timeString forKey:#"time"];
[FBDialogs presentShareDialogWithOpenGraphAction:action
actionType:#"shapeshuffle:solve"
previewPropertyName:#"puzzle"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
Had the same issue. Make sure the App Domains in Basic Info contains the oAuth domain. The odd thing I found is that in order to add this you need to enable this can only be added if you enable Page Tab or Mobile Web or one of the other options.
I think i may know the reason that (#"url": #"http://test.com")->this may use the facebook app developer center offer.
click Open Graph
click Stories
then you will see your custom story on right side
click Get Code,then you will get the URL you need!
and (#"type": #"appsterbator.app_idea")->this may need use like this->(your_app_namespace:action_type)
Good luck!
To problem with: "Could not generate preview text" come from attempts to share the same content several times.
Try to change content that you share each time you check the functionality of open graph.
A condition that causes this which has not been described yet is case sensitivity of the action and property name, which must be lowercase. To illustrate note the 'must_be_lowercase' in the following:
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:#"http://link/" forKey:#"**must_be_lowercase**"];
[FBDialogs presentShareDialogWithOpenGraphAction:action
actionType:#"xxxx"
previewPropertyName:#"**must_be_lowercase**"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
This is a lovely generic error message! Another possible cause I've encountered is the size of the OpenGraph image being posted.
Although Facebook documentation states images must be 200x200px to 1500x1500px, my initial attempts with a 350x350px image failed with the “Could not generate preview text” error. The same image at 600x600px on the other hand works perfectly.

Now I've got simple request to Facebook api:
me/feed?fields=type,story,caption,message,picture,comments&limit=20&offset=0
It works fine, but in the comments section, there are message, name and user id who post this comment, but I also need a photo-link. Of course I can send more requests to get user-photo. But I think it would be silly decision. Maybe there is way to send fql or batch request to get all fields I need in one request?
P.S. I already know how to do it with ruby, but i need some example which I can use in ios app.
Edit: Also I've got simple example, which do a little more detailed listing, but also without photo. What I should add to request2, to get photo?
JSFacebookRequest *request1 = [JSFacebookRequest requestWithGraphPath:#"me/feed? fields=story,message,comments&offset=15&limit=5"];
[request1 setName:#"get-field"];
JSFacebookRequest *request2 = [JSFacebookRequest requestWithGraphPath:#"?ids={result=get-field:$.data..id}"];
[facebook fetchRequests:[NSArray arrayWithObjects:request1, request2, nil] onSuccess:^(NSArray *responseObjects) {
NSLog(#"Responses:\n%#", responseObjects);
} onError:^(NSError *error) {
NSLog(#"Error: %#", [error localizedDescription]);
}];
Perhaps I'm misunderstanding your situation, but it seems to me that you're over-complicating things. If you've got the user id, you can build the needed URL like so:
https://graph.facebook.com/<user_id>/picture
If that doesn't give you the desired image size, there are other options listed here. (See the 'images' parameter, for example.)
