Facebook SDK and iOS - ios

Question

I am trying to post a status using Facebook SDK.
Some of the users are already signed in using Facebook.
So I have this code:
if (FBSession.activeSession.isOpen) {
NSLog(#"Already Open%#",[[FBSession activeSession] accessTokenData].accessToken);
// NSString *tok = [[FBSession activeSession] accessTokenData].accessToken;
NSArray *permissions = [NSArray arrayWithObjects:#"publish_actions", nil];
[[FBSession activeSession] requestNewPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session,NSError *error) {
if(!error){
NSLog(#"Publish Permission Granted");
}
else
{
NSLog(#"Publish to get Read Permission");
} }];
//Remove indicator
[_activityView removeFromSuperview];
} else {
// OPEN Session!
[FBSession openActiveSessionWithReadPermissions:nil
allowLoginUI:YES
completionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// if login fails for any reason, we alert
if (error) {
// show error to user.
} else if (FB_ISSESSIONOPENWITHSTATE(status)) {
// no error, so we proceed with requesting user details of current facebook session.
NSLog(#"----%#",[session accessTokenData].accessToken);
//NSString *tok = [session accessTokenData].accessToken;
NSArray *permissions = [NSArray arrayWithObjects:#"publish_actions", nil];
[[FBSession activeSession] requestNewPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session,NSError *error) {
if(!error){
NSLog(#"Publish Permission Granted");
}
else
{
NSLog(#"Publish to get Read Permission");
} }];
[_activityView removeFromSuperview];
// [self promptUserWithAccountName]; // a custom method - see below:
}
}];
}
So lets focus on the first part which is suppose that the user has open session( the second one is just opening a new one in case that is no session available). How I am going to post a status with a url and a picture after granting publish permissions? Facebook examples are not helping at all. I found some other examples but most of them are outdated.
I managed to post a simple post with:
FBRequest *postRequest = [FBRequest requestForPostStatusUpdate:#"hi" ];
[postRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
// TODO: Check for success / failure here
}];
after granding publish permission. I want something similar with url description imgurl and title.

This is how I did it, in my ibaction method:
Sharing Image:
UIImage *img = myImage;
FBLoginView *loginview = [[FBLoginView alloc] init];
loginview.delegate = self;
[self performPublishAction:^{
[FBRequestConnection startForUploadPhoto:img
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[self showAlert:#"Photo Post" result:result error:error];
}];
}];
Sharing URL:
NSURL *urlToShare = [NSURL URLWithString:#"http://developers.facebook.com/ios"];
FBAppCall *appCall = [FBDialogs presentShareDialogWithLink:urlToShare
name:#"Hello Facebook"
caption:nil
description:#"The 'Hello Facebook' sample application showcases simple Facebook integration."
picture:nil
clientState:nil
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if (error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
Add these as well:
- (void) performPublishAction:(void (^)(void)) action
{
if([[FBSession activeSession]isOpen])
{
if ([FBSession.activeSession.permissions indexOfObject:#"publish_actions"] == NSNotFound) {
// if we don't already have the permission, then we request it now
[FBSession.activeSession requestNewPublishPermissions:#[#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
action();
}
//For this example, ignore errors (such as if user cancels).
}];
} else {
action();
}
}
else
{
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
if (!error && status == FBSessionStateOpen) {
}else{
NSLog(#"Session error");
[self fbResync];
[NSThread sleepForTimeInterval:0.5]; //half a second
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error){
}];
}
}];
}
}
- (void)loginViewShowingLoggedInUser:(FBLoginView *)loginView
{
}
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
user:(id<FBGraphUser>)user
{
self.loggedInUser = user;
}
- (void)loginViewShowingLoggedOutUser:(FBLoginView *)loginView
{
self.loggedInUser = nil;
}
-(void)fbResync
{
ACAccountStore *accountStore;
ACAccountType *accountTypeFB;
if ((accountStore = [[ACAccountStore alloc] init]) && (accountTypeFB = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook] ) ){
NSArray *fbAccounts = [accountStore accountsWithAccountType:accountTypeFB];
id account;
if (fbAccounts && [fbAccounts count] > 0 && (account = [fbAccounts objectAtIndex:0])){
[accountStore renewCredentialsForAccount:account completion:^(ACAccountCredentialRenewResult renewResult, NSError *error) {
//we don't actually need to inspect renewResult or error.
if (error){
}
}];
}
}
}
Hope this helps... Look at HelloFacebookSample in Facebook SDK Samples.
Try this:
[self performPublishAction:^{
NSString *message = [NSString stringWithFormat:#"Updating status for %# at %#", self.loggedInUser.first_name, [NSDate date]];
[FBRequestConnection startForPostStatusUpdate:message
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[self showAlert:message result:result error:error];
self.buttonPostStatus.enabled = YES;
}];
self.buttonPostStatus.enabled = NO;
}];
