Facebook invite on simulator is ok, but can not show appInviteDialog on iOS device

Question

At the same time, loginDialog and shareDialog can show.

Show appInviteDialog error is:

Domain=com.facebook.sdk.core Code=9 "(null)"

Is there any possibility for a network problem, because I use VPN, but the simulator also uses VPN.

The code:

FBSDKAppInviteContent *content = [[FBSDKAppInviteContent alloc] init];
content.appLinkURL = [NSURL URLWithString:@"https://fb.me/319673994858989"];
[FBSDKAppInviteDialog showFromViewController:self withContent:content delegate:self];

Answer 1

I solve this problem by using local iPhone VPN,and appInviteDialog can show. Before I use computer share network,it may cause network problems for the iOS change the net work safety requirement.Login problems occurred for this network reason before.
