Facebook SDK iOS - Sharing custom stories - ios

Question

I would like to share a custom story by Facebook SDK for iOS. I tried to do it in these ways, but none of them works:
Does not log anything
[FBGraphObject openGraphObjectForPostWithType:#"Lorem ipsum"
title:#"Lorem ipsum"
image:#"https://example.com/cooking-app/images/Lamb-Vindaloo.png"
url:#"https://example.com/cooking-app/meal/Lamb-Vindaloo.html"
description:#"Spicy curry of lamb and potatoes"];
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:cell.params forKey:slugs[self.categoryID]];
[FBDialogs presentShareDialogWithOpenGraphAction:action
actionType:[NSString stringWithFormat:#"Lorem ipsum:%#", slugs[self.categoryID]]
previewPropertyName:slugs[self.categoryID]
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
The operation couldn't be completed. (com.facebook.sdk error 5.)
[FBSession openActiveSessionWithAllowLoginUI:NO];
FBRequest *request = [FBRequest requestForPostWithGraphPath:#"/me/Lorem ipsum" graphObject:#{#"object": cell.params}];
[request setHTTPMethod:#"POST"];
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error)
{
if (!error)
{
// Sucess! Include your code to handle the results here
NSLog(#"result: %#", result);
NSString *alertTitle = #"Object successfully created";
NSString *alertText = #"An object has been created";
[[[UIAlertView alloc] initWithTitle:alertTitle
message:alertText
delegate:self
cancelButtonTitle:#"OK!"
otherButtonTitles:nil] show];
}
else
{
NSLog(#"%#", [error localizedDescription]);
}
}];
cell.params
cell.params = [FBGraphObject openGraphObjectForPostWithType:[NSString stringWithFormat:#"Lorem ipsum:%#", slugs[self.categoryID]]
title:#"Lorem ipsum"
image:[NSString stringWithFormat:#"https://example.com/cooking-app/images/%#.png", slugs[self.categoryID]]
url:#"https://example.com"
description:#"Lorem ipsum"];
cell.params[#"Lorem ipsum"] = #{#"minutes": #5, #"seconds": #37, #"hours": #1};
