Answer 1

FBSDKLoginManager is your need, it has logOut method but you might have to use your custom login

e.g.

FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
  if (error) {
    // Process error
  } else if (result.isCancelled) {
    // Handle cancellations
  } else {
    // If you ask for multiple permissions at once, you
    // should check if specific permissions missing
    if ([result.grantedPermissions containsObject:@"email"]) {
      // Do work
    }
  }
}];

//then logout
[loginManager logOut];
