iOS Facebook Open Graph Get Link For Post - ios

Question

I'm trying to get the link to a Facebook Page's Post. However, links only show up under the actions field, and for every like, comment, or share, it lists the link again. I use:
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"/v2.3/116178611870507/feed?limit=20" parameters:[NSMutableDictionary dictionaryWithObject:#"id, actions, message, full_picture" forKey:#"fields"]]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error)
The result shows up in console as
{
data = (
{
actions = (
{
link = "https://www.facebook.com/116178611870507/posts/534581860030178";
name = Comment;
},
{
link = "https://www.facebook.com/116178611870507/posts/534581860030178";
name = Like;
},
{
link = "https://www.facebook.com/116178611870507/posts/534581860030178";
name = Share;
}
);
I guess my question would be, how can I access the link in there, but limit to only pulling it one time instead of for every like share or comment?

Try this code :
NSMutableArray *link = [[NSMutableArray alloc]init];
NSMutableArray *dataArr = [[NSMutableArray alloc] initWithArray:[yourFacebookResult objectForKey:#"data"]];
for (int i=0; i < dataArr.count; i++) {
for (int j=0; j < [[[dataArr objectAtIndex:i] objectForKey:#"actions"] count]; j++) {
[link addObject:[[[[dataArr objectAtIndex:i] objectForKey:#"actions"] objectAtIndex:j] objectForKey:#"link"]];
}
}
NSLog(#"Your all link -> %#",link);
