How to get photos of a facebook album in iPhone SDK? - ios

I am developing a iPhone application which get facebook album with this URL https://graph.facebook.com/me/albums?access_token=2227470867|2.ZJr73vaEvFeN4fI_A70RFw__.3600.1297090800-100000566543036|WmgxdwULBgKXl8J7ksGIA1tyGik
Now i want to get photos from this album.
Any Idea will be appreciated.
Thanks in Advance.

So /me/albums returns an array of Album objects, each of which has an id.
If an album had an id of 99394368305, you can go to
https://graph.facebook.com/99394368305/photos
to get an array of photo objects.
Each of these will have the picture and source properties to get the image data from facebook.
They will all have an images array as well if you want pre-scaled images instead of just the originals.
All the facebook queries give JSON back - I'm assuming that you know how to parse this?

It takes lot of time because of following steps;
1) get uid of friend using :
NSString *urlString=[NSString stringWithFormat:#"https://graph.facebook.com/me/friends?access_token=%#&fields=id,picture,name,birthday",fbGraph.accessToken];
2) put friends uid to get album id:
NSString *urlString1=[NSString stringWithFormat:#"https://graph.facebook.com/%#/albums?access_token=%#",obj.uid,fbGraph.accessToken];
NSString *album = [[[_response1 objectForKey:#"data"]objectAtIndex:j]objectForKey:#"name"];
if ([album isEqualToString:#"Profile Pictures"])
{
albumid = [[[_response1 objectForKey:#"data"]objectAtIndex:j]objectForKey:#"id"];
}
3) then put the album id to get the picture from that album:
NSString *albumUrl=[NSString stringWithFormat:#"https://graph.facebook.com/%#/photos?type=album&access_token=%#",albumid,fbGraph.accessToken];
NSString *picUrl=[[[[[_response2 objectForKey:#"data"]objectAtIndex:0]objectForKey:#"images"]objectAtIndex:0]objectForKey:#"source"];
Kindly tell me some other method to get profile picture with large size in a single step to save time.

The code below should do the right job for you. It gets albums for logged user and then requests for photos of this albums. In the place where is a comment you will have the access to all photos. For more info you can refer to docs:
FBRequest *request = [FBRequest requestForGraphPath:#"me/albums"];
[request startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary <FBGraphUser> *my, NSError *error) {
if ([my[#"data"]count]) {
for (FBGraphObject *obj in my[#"data"]) {
FBRequest *r = [FBRequest requestForGraphPath:[NSString stringWithFormat:#"/%#/photos", obj[#"id"]]];
[r startWithCompletionHandler:^(FBRequestConnection *c, NSDictionary <FBGraphUser> *m, NSError *err) {
//here you will get pictures for each album
}];
}
}
}];

Facebook developers new code:
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"/{user-id}"
parameters:params
HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
// Handle the result
}];

Chek just updated photo permission on Facebook

I'm using this code to upload a photo on the Facebook user wall but the result dictionary return to me only photoid and postid, i need to know the permission level of the post that i have just share (during sharing process in native app the user can select Public,friends,only me...), There a way to know this permission?
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:#"", #"message", nil];
[params setObject:Picture forKey:#"source"];
[FBRequestConnection startWithGraphPath:#"me/photos"
parameters:params
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error)
{
if (error)
{
//showing an alert for failure
}
else
{
//showing an alert for success
NSString *phoId=[NSString stringWithFormat:#"%#",[result valueForKey:#"id"]];
NSString *PostId=[NSString stringWithFormat:#"%#",[result valueForKey:#"post_id"]];
}
}];
You can do another Graph API Call using the post id of the photo you have just uploaded. The specific field you want to ask for is called 'privacy'. This field is an object. One of its properties is 'value', which can be one of the following:
Everyone
All Friends
Friends of Friends
Self
Custom
From this, you can check the privacy people have specified on your post and adjust accordingly.

How to Post image on FB Users wall with the message ?(without using URL for image)

I am trying to post on users wall using ios app by using FB New graph API 3.17.1.But when I post using the graph path me/photos, it will create an bunch of post at one location instead of posting the images as separate story.
I did lot of R&D and found this Post photo on user's wall using Facebook iOS SDK
I used below method to post on user's wall
NSMutableDictionary* postParams = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
#"<Image URL>", #"picture",
#"Facebook SDK for iOS", #"name",
#"build apps.", #"caption",
#"testing for my app.", #"description",
nil];
[FBRequestConnection startWithGraphPath:#"me/feed"
parameters:postParams
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection, id result,NSError *error)
{
if (error)
{
NSLog(#"Error in uploading the photo %#",error);
}
}];
This method does paste the image on user's wall but for this image has to be uploaded somewhere on internet and we have supply the URL of same.And additionally it makes image visibility very less compared to image posted using me/potos.
[FBRequestConnection startWithGraphPath:#"me/photos" parameters:params
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection*connection, id result, NSError *error)
{
NSLog(#"Error : %#",error);
NSLog(#"%#",result);
}];
I used above method but it will group the photos into bunch and make the album on the users wall after 3-4 post. And additionally it has limitation of max 25 post per app per day. So this method is negligible.
Please let me know any alternative way, if anyone has used.I would be very thankful.

How to get the list of Facebook friends who have not installed the app?

I'm developing a social networking app. I've integrated Facebook SDK 3.14 in my iOS App. Now, I want to get the list of all my Facebook friends so I can invite those friends who are not using the app and send friend requests to those friends who have already installed the app.
I can get the list of friends who already use my apps using "/me/friends".
[FBRequestConnection startWithGraphPath:#"/me/friends"
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSLog(#"All == %#", result);
}];
It gives friends' Facebook ids (ex. id = 654330727444458) in response so that I can send friend requests to them.
To get the list of all Facebook friends who have not downloaded the app and if I want to invite those, I need to get all friends using "me/taggable_friends" (Please correct me if I'm wrong).
[FBRequestConnection startWithGraphPath:#"/me/taggable_friends"
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSlog("%#", result);
}];
In the taggable_friends response I'm getting friend's id as id = "AaLYBzZzHdzCmlytqyMAjO0OLDZIOs74Urn93ikeRmmTB3vX_Xl81OYUt4XnoWG0BDLuX67umVkheVdDjzyvm0fcqMqu84GgM9JnNHc-1B63eg" which is friend's token id and it's not unique. I couldn't use it instead, have to use Facebook Id of friend to invite them. Unfortunately, I couldn't get it in the taggable friend response.
This is only possible on the Facebook API v1 which stops working next April or so. Even now only existing Facebook apps will allow you to use V1 so if you don't have an old enough app you are not able to do this. In V2 you can only get friends who have also signed in to the same app but the user id's are unique to the application to prevent exactly this. I guess Facebook reasons that by doing this is stops people spamming their friends via apps so much :/
As #joelrb says you can create a canvas app for a game and use invitable_friends but FB will vet your "game" so you can't really cheat.
See https://developers.facebook.com/docs/apps/changelog/ for more info.
TLDR; post to wall is all you can do. Tough. Sorry.
Use the installed field of a user. Like so:
NSMutableArray *notYetUsers = [NSMutableArray array];
FBRequest *fbRequest = [FBRequest requestForGraphPath:#"me/friends?fields=installed"];
[fbRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSAssert(!error, error.localizedDescription);
NSArray *friends = [(NSDictionary *)result objectForKey:#"data"];
for (NSDictionary<FBGraphUser> *user in friends) {
if ([user[#"installed"] isEqual:#(NO)])
[notYetUsers addObject:user];
}
}];
notYetUsers would contain all friends who have not installed the app yet.
- (void)getFBFriendsWithCompletion:(void (^)(NSError *, id))callback
{
NSString *query = #"select uid, name, is_app_user "
#"from user "
#"where uid in (select uid2 from friend where uid1=me() )";
NSDictionary *queryParam =
[NSDictionary dictionaryWithObjectsAndKeys:query, #"q", nil];
// Make the API request that uses FQL
[FBRequestConnection startWithGraphPath:#"/fql"
parameters:queryParam
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
if (callback)
callback(error, result);
}];
}
- (void)foo
{
[self getFBFriendsWithCompletion:^(NSError *error, id result) {
if (!error)
{
NSMutableArray *friendsUsingApp = [NSMutableArray array];
NSMutableArray *friendsNotUsingApp = [NSMutableArray array];
for (NSDictionary *data in result[#"data"]) {
if ([data[#"is_app_user"] boolValue] == NO) {
[friendsNotUsingApp addObject:data];
} else {
[friendsUsingApp addObject:data];
}
}
// Do something with friendsUsingApp and friendsNotUsingApp
}
}];
}
taggable_friends refers to a list of friends that can be tagged or mentioned in stories published to Facebook. The result you got is just a tagging token which can only be used in order to tag a friend, and for no other purpose.
Although this refers to a game app, it's easier I think if you use the invitable_friends API. But it requires a Facebook Canvas app implementation. You may just provide a notice in your Canvas for users to just use the mobile app instead, etc.
This is the tutorial that uses invitable_friends API: https://developers.facebook.com/docs/games/mobile/ios-tutorial/
And, the invitable_friends API details:
https://developers.facebook.com/docs/games/invitable-friends/v2.0
You can try this to get the IDs of Friends app users:
NSMutableArray *appFriendUsers = [[NSMutableArray alloc] init];
[[FBRequest requestForGraphPath:#"me/friends?fields=installed"]
startWithCompletionHandler:
^(FBRequestConnection *connection,
NSDictionary *result,
NSError *error) {
//if result, no errors
if (!error && result)
{
//result dictionary in key "data"
NSArray *allFriendsList = [result objectForKey:#"data"];
if ([allFriendsList count] > 0)
{
// Loop
for (NSDictionary *aFriendData in allFriendsList) {
// Friend installed app?
if ([aFriendData objectForKey:#"installed"]) {
[appFriendUsers addObject: [aFriendData objectForKey:#"id"]];
break;
}
}
}
}
}];

Xcode, fetch Facebook hometown name

I am beginner in ObjectiveC programming language.
I developing application, using Facebook.
I try to fetch Hometown name.
Now, i want copy "Sveti Martin na Muri" to string to display in tableview.
I use:
FBRequest *friendRequest = [FBRequest requestForMe];
[friendRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error)
and output is:
NSLog(#"%#", [result objectForKey:#"hometown"]);
{
id = 107836872573218;
name = "Sveti Martin na Muri";
}
The same problem i have with relationship, work, location and education.
How can I access only name?
Sorry for my bad English.
greetings from Croatia.
The following code:
[result objectForKey:#"hometown"]
returns a NSDictionary with two field id and name.
You can access the name like:
NSLog(#"%#", [[result objectForKey:#"hometown"] objectForKey:#"name"]);
