  FB.ui(params, function(obj) { console.log(obj); });

the error is when is calling FB.ui()

I really don't know what to do, or where I can start looking, thanks for any help!!!

Answer 1

This is caused by a bug in the FacebookConnect plugin following the Cordova 2.4.0 release (which uses NSJSONSerialization, and so returned objects are now immutable).

A pull request has been made on Github which contains the fixes: https://github.com/phonegap/phonegap-facebook-plugin/pull/251

In the meantime, you could manually make the following changes to FacebookConnectPlugin.m:

Replace line 284:

NSMutableDictionary *options = [[command.arguments lastObject] mutableCopy];

Add the following after line 310:

[options release];
