Subscribing to log on iOS not working

Hi, I am trying to create my own in app log window. I am using Application.logMessageReceived in order to subscribe to the logs. It works in the editor and running on Android, but the subscribed method is not called in iOS. I have it set up identically to the example [here][1]. The output string is never filled. Any advice would be greatly appreciated. Thanks, Noah [1]: http://docs.unity3d.com/ScriptReference/Application-logMessageReceived.html
