Clearing PlayerPrefs without causing Facebook logout?

Hi,

I'm looking for a way to clear everything that doesn't contain 'com.facebook.sdk' in the key, as currently, clearing PlayerPrefs appears to be causing the player to be logged out of FB.

(Looking at the .plist file directly, the Facebook SDK adds a couple of keys to track it's state, and it's looking like clearing PlayerPrefs causes this to be lost)

Is there really no way to iterate through PlayerPrefs keys? - to remove them selectively?

(The reason for clearing PlayerPrefs is that we're moving our savegame from to a separate file in our next app update. Our save has grown fairly large, so we don't want to waste memory having an unused old copy left behind)

 

Why dont you try something like this:

Code (CSharp):

1. void ClearPlayerPrefsSafely()
2. {
3.     string _Key1ToKeep = PlayerPrefs.GetString("FBPassword");
4.     int _Int1ToKeep = PlayerPrefs.GetInt("FBUserID");
5.     PlayerPrefs.DeleteAll();
6.     PlayerPrefs.SetString("FBPassword", _Key1ToKeep);
7.     PlayerPrefs.SetInt("FBUserID", _Int1ToKeep);
8.     PlayerPrefs.Save();
9. }
