I am trying to post an OpenGraph story to Facebook on iOS. I have been following this tutorial.
https://developers.facebook.com/docs/ios/open-graph/
I have also been refering to
I am able to get the post to upload to FB but the image is missing. I have tried several variations but have been finding the documentation to be sparse. Any insights would be appreciated:
UIImage *loadedImage = [UIImage imageWithContentsOfFile:file];
NSArray* image = @[@{@"url":loadedImage, @"user_generated": @"true"}];
id<FBGraphObject> objectname =
[FBGraphObject openGraphObjectForPostWithType:@"namespacename:objectname"
title:@"objectname"
image:nil
url:nil
description:@"description"];
id<FBOpenGraphAction> actionname = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[actionname setObject:image forKey:@"image"];
[actionname setObject:objectname forKey:@"objectname"];
// Check if the Facebook app is installed and we can present the share dialog
FBOpenGraphActionParams *params = [[FBOpenGraphActionParams alloc] init];
params.action = actionname;
params.actionType = @"namespacename:objectname";
// If the Facebook app is installed and we can present the share dialog
if ([FBDialogs canPresentShareDialogWithOpenGraphActionParams:params]) {
[FBDialogs presentShareDialogWithOpenGraphAction:actionname
actionType:@"namespacename:actionname"
previewPropertyName:@"objectname"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
// There was an error
NSLog(@"Error publishing story: %@", error.description);
} else {
// Success
NSLog(@"result %@", results);
}
}];
} else {
NSLog(@"cant show the share dialog ");
}
I have thoroughly examined the code and the only difference I can find is that instead of picking an image from the gallery I am loading it from a file. As I mentioned the post goes through and is shared on Facebook however the image does not appear either on the feed or in the clickable object on the news feed. I can see a thumbnail of the image when the sharing dialog loads so I believe it is loading fine. Any help would be appreciated. Thanks in advance.
