Is it ok to send normal messages via Interface Builder's binding’s model key path?
I want to enable some menu items only if the main window of my application is visible. I simply tried the following to see what would happen:
In the bindings inspector of the menu item i bind Availability-Enabled to the AppDelegate
and set the model key path to self.window.isVisible
.
This seems to work well, but is it meant to be used like this? Legal in the AppStore?
A little exclamation mark appears next to my model key path..
