Interface Builder Does Not Recognize Toolbar Buttons

Answer 1

All that matters is that they have an IBOutlet, and are declared correctly for the ui element you are trying to connect to. A @property isn't essential (but is good practice). You can have the IBOutlet on either the declaration, the @property, or both.

Buttons in a toolbar are UIBarButtonItems; buttons on a plain view are UIButtons. They are different things. You seem confused on this issue, so please double check your code.

Answer 2

I am also having the same problem. My button background images all who up as white spaces. They are the right size and do display but they are just solid white. They look fine in everything else even xcode, and preview. I'm at a loss at why they don't appear as the background of my toolbar buttons
