Text and image is invisible when integrated AMBubbleTableViewController

[codingguy]

i integrated EGOTableViewPullRefresh and AMBubbleTableViewController in the app (build sdk: iOS 6.1)

but the text(like "Release to refresh...") and image is invisible

could you confirm that it is possible for using EGOTableViewPullRefresh and AMBubbleTableViewController in one table view ?

if yes, could you give me some suggestions ?

Thank you !
