I had that same problem one time, however I removed the code to create the button, cleaned targets, built it. Then re added the button and it was fine.
Do you have a tint color on the toolbar or navigation bar that you are using in IB?
i assume then any button sitting on the toolbar is affected by its colour and tint?
your assumption is correct.
that sucks then.
what if i want a blue bar with a red button, how would i achieve that ?
make your own?
