How to get a friend's post of facebook sdk v4 - ios

Question

I'm using Facebook SDK v4 to get all the posts of a friend. I use the following code
FBSDKLoginManager* loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithReadPermissions:#[#"user_posts"] handler:^(FBSDKLoginManagerLoginResult *result, NSError* error) {
if (error) {
// Process error
NSLog(#"");
} else if (result.isCancelled) {
// Handle cancellations
NSLog(#"");
} else {
// If you ask for multiple permissions at once, you
// should check if specific permissions missing
if ([result.grantedPermissions containsObject:#"user_posts"]) {
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"/10002434324342/posts"
parameters:nil
HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
// Handle the result
if (error) {
NSLog(#"");
}
}];
}
}
}];
10002434324342 is an example of facebookID. It just return an empty data list.
Can anyone tell me how to do this

Answer 1

Friend permissions have been removed with v2.0, you can only get data of users who authorized your App too, with the correct permissions. user_posts should always be used with /me/posts.

You can try
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"/{user-id-a}/friends/{user-id-b}"
parameters:params
HTTPMethod:#"POST"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
// Handle the result
}];
