I need to upload photo to user's album and let user share with some messages. I've uploaded photo to app album using [FBRequestConnection startForUploadPhoto:photo completionHandler:handler], but is there any way to share the uploaded picture?
Thanks.
You can use the startWithGraphPath method provide in the Facebook SDK:
+ (FBRequestConnection*)startWithGraphPath:(NSString*)graphPath
parameters:(NSDictionary*)parameters
HTTPMethod:(NSString*)HTTPMethod
completionHandler:(FBRequestHandler)handler;
Here my code I used to upload a photo with a message, so the photo appear on my timeline with the message:
- (void) requestPostPhoto:(UIImage *)photo withMessage:(NSString *)message
{
if( [self isLocalUserConnected] )
{
NSMutableDictionary * params = [[NSMutableDictionary alloc] init];
if( message != nil || ![message isEqualToString:#""] )
{
[params setObject:message forKey:#"message"];
}
[params setObject:UIImagePNGRepresentation(photo) forKey:#"picture"];
[FBRequestConnection startWithGraphPath:#"me/photos"
parameters:params
HTTPMethod:#"POST" completionHandler:^(FBRequestConnection * connection, id result, NSError * error)
{
//TODO: add some code here
}];
}
}
I think you can change in the startWithGraphPath: the #"me" by the facebook user ID.

I am posting a picture and dummy text on a facebook page with the Page Id "848190045198980".I am signing in using my facebook credentials.Also I have admin role for the specific page.So I am just getting the basic permissions from facebook.Below is the request and the response.
Request :
UIImage * productImage = [UIImage imageNamed:#"corporate.png"];
NSData * imageData = UIImagePNGRepresentation(productImage);
NSDictionary *params = #{#"message": #"Hello XYZ", #"source":imageData};
[FBRequestConnection startWithGraphPath:#"/848190045198980/photos" parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if(!error)
{
if(completionBlock)
{
NSLog(#"%#",result);
completionBlock(YES,result,nil);
}
}
else
{
if(completionBlock)
completionBlock(NO,nil,error);
}
}];
Response :
{"id":"1481175438805031","post_id":"848190045198980_1481175438805031"}
Expected Result : My Post should show up on the Facebook Page in "Posts to Page" Section.
Actual Result : Nothing Shows Up.
Please point me in the right direction as to what I am missing here.I have checked the API Doc several times and I am finding it real tough as to where I am missing something.

I am implementing the Facebook SDK into my app . I am using FBLoginView to login with Facebook. I have a UIButton, which I'm using to share on a user's Facebook wall. Now I don't want to login using FBLoginView , i want to check if there is a Facebook app, and if the user has logged in.

{
FBFriendPickerViewController *friendPickerController = [[FBFriendPickerViewController alloc] init];

// Use the modal wrapper method to display the picker.
[friendPickerController presentModallyFromViewController:self animated:YES handler:
^(FBViewController *sender, BOOL donePressed) {
if (!donePressed) {
return;
}

NSLog(#"Error publishing story.");
}
else
{
if (result == FBWebDialogResultDialogNotCompleted) {
// User clicked the "x" icon
NSLog(#"User canceled story publishing.");
}
else
{
// Handle the publish feed callback
//Tell the user that it worked.
}
}
}];
}];
}
}];
}
I am assuming that you are using iOS 6 sdk. In which case, Use below code (workable for device) :
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
//user is already logged in using iOS integrated FB a/c
}
else
{
//user is not logged in
}
Note: FBSession can't check this criteria. So session check with FBSession has a different meaning from above code.
Regards,
Check for the URL Scheme fb://
[[UIApplication sharedApplication] canOpenURL:#"fb://"] returns YES if Facebook App is installed. This post lists, de available URL schemes for Facebook: https://stackoverflow.com/a/5707825/1511668
Maybe fb://online is what you are looking for.
I want to post some text to a users wall using the facebook sdk in an iOS app.
Is posting an open graph story now the only way to do that?
I've found with open graph stories they are really strange, you can only post things in the format "user x a y" where you preset x and y directly on facebook, like user ata a pizza or user played a game. Setting up each one is pretty laborious too because you have to create a .php object on an external server for each one.
Am I missing something or is there a simpler way to go about this?
Figured it out by browsing the facebook tutorials a bit more.
-(void) postWithText: (NSString*) message

nil];
if ([FBSession.activeSession.permissions indexOfObject:#"publish_actions"] == NSNotFound)
{
// No permissions found in session, ask for it
[FBSession.activeSession requestNewPublishPermissions: [NSArray arrayWithObject:#"publish_actions"]
defaultAudience: FBSessionDefaultAudienceFriends
completionHandler: ^(FBSession *session, NSError *error)
{
if (!error)
{
// If permissions granted and not already posting then publish the story
if (!m_postingInProgress)
{
[self postToWall: params];
}
}
}];
}
else
{
// If permissions present and not already posting then publish the story
if (!m_postingInProgress)
{
[self postToWall: params];
}
}
}
-(void) postToWall: (NSMutableDictionary*) params
{
m_postingInProgress = YES; //for not allowing multiple hits
[FBRequestConnection startWithGraphPath:#"me/feed"

HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error)
{
if (error)
{
//showing an alert for failure
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:#"Post Failed"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
m_postingInProgress = NO;
}];
}
the easiest way of sharing something from your iOS app is using the UIActivityViewController class, here you can find the documentation of the class and here a good example of use. It is as simple as:
NSString *textToShare = #”I just shared this from my App”;
UIImage *imageToShare = [UIImage imageNamed:#"Image.png"];
NSURL *urlToShare = [NSURL URLWithString:#"http://www.bronron.com"];
NSArray *activityItems = #[textToShare, imageToShare, urlToShare];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityVC animated:TRUE completion:nil];
This will only work on iOS 6 and it makes use of the Facebook account configured in the user settings, and the Facebook SDK is not needed.
You can use Graph API as well.
After all the basic steps to create facebook app with iOS, you can start to enjoy the functionality of Graph API. The code below will post "hello world!" on your wall:
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>
...
//to get the permission
//https://developers.facebook.com/docs/facebook-login/ios/permissions
if ([[FBSDKAccessToken currentAccessToken] hasGranted:#"publish_actions"]) {
NSLog(#"publish_actions is already granted.");
} else {
FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithPublishPermissions:#[#"publish_actions"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
//TODO: process error or result.
}];
}
if ([[FBSDKAccessToken currentAccessToken] hasGranted:#"publish_actions"]) {
[[[FBSDKGraphRequest alloc]
initWithGraphPath:#"me/feed"
parameters: #{ #"message" : #"hello world!"}
HTTPMethod:#"POST"]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(#"Post id:%#", result[#"id"]);
}
}];
}
...

I am trying to post a message on my wall and wanted to tag multiple users at a time in this post. I tried the various options on the FB post page but couldn't do it. May be I am not doing it right. Any help is appreciated and this is how I am doing it...
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"Test 2",#"message",
#"100004311843201,1039844409", #"to",
nil];
[self.appDelegate.facebook requestWithGraphPath:#"me/feed" andParams:params andHttpMethod:#"POST" andDelegate:self];
I have also tried message_tags but that doesn't seem to work as well.
You would need to use Open Graph to tag people with a message. The me/feed Graph API endpoint doesn't support this.
Mentions Tagging
https://developers.facebook.com/docs/technical-guides/opengraph/mention-tagging/
Action Tagging:
https://developers.facebook.com/docs/technical-guides/opengraph/publish-action/
You can take a look at the Scrumptious sample app that comes included with the latest Facebook SDK for iOS to see how to do this.
To tag a friend in ur fb status ..you need "facebook id" of your friend by using FBFriendPickerViewController and "place id" using FBPlacePickerViewController. Following code will help you.
NSString *apiPath = nil;
apiPath = #"me/feed";
if(![self.selectedPlaceID isEqualToString:#""]) {
[params setObject:_selectedPlaceID forKey:#"place"];
}
NSString *tag = nil;
if(mSelectedFriends != nil){
for (NSDictionary *user in mSelectedFriends) {
tag = [[NSString alloc] initWithFormat:#"%#",[user objectForKey:#"id"] ];
[tags addObject:tag];
}
NSString *friendIdsSeparation=[tags componentsJoinedByString:#","];
NSString *friendIds = [[NSString alloc] initWithFormat:#"[%#]",friendIdsSeparation ];
[params setObject:friendIds forKey:#"tags"];
}
FBRequest *request = [[[FBRequest alloc] initWithSession:_fbSession graphPath:apiPath parameters:params HTTPMethod:#"POST"] autorelease];
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[SVProgressHUD dismiss];
if (error) {
NSLog(#"Error ===== %#",error.description);
if (_delegate != nil) {
[_delegate facebookConnectFail:error requestType:FBRequestTypePostOnWall];
}else{
NSLog(#"Error ===== %#",error.description);
}
}else{
if (_delegate != nil) {
[_delegate faceboookConnectSuccess:self requestType:FBRequestTypePostOnWall];
}
}
If you followed the tutorial on how to setup Open Graph for iOS, you can do something like this if you use the friendsPickerController:
// Create an action
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
//Iterate over selected friends
if ([friendPickerController.selection count] > 0) {
NSMutableArray *temp = [NSMutableArray new];
for (id<FBGraphUser> user in self.friendPickerController.selection) {
NSLog(#"Friend selected: %#", user.name);
[temp addObject:[NSString stringWithFormat:#"%#", user.id]];
}
[action setTags:temp];
}
Basically, you can set an array of friend's ids on the "tags" property on an action
I've integrated the FB SDK 3.1 in my ios application to support both iOS5 and iOS6.
I can successfully share an image on my FB wall for iOS6 but I'm not able to make the sharing work for iOS5.
Anyone have idea using FBsdk 3.1 how to achieve this:
1) Share image using FBsdk 3.1 for iOS5 and iOS6(Done)
2) Fetch user albums photos for both iOS5 and iOS6.
Thanks.
#Max: You can post photo on facebook as below...
[self performPublishAction:^{
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
imageToShare, #"picture",
Description, #"caption",
FACEBOOK_ACCESS_TOKEN],#"access_token",
nil];
[FBRequestConnection startWithGraphPath:#"me/photos" parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(#"--- Post photo Result = %#",result);
}else{
NSLog(#"--- Error!!! :( = %#",error);
}
}];
}];
