I’m using a lot of “custom identifiers” for Toolbar Items, which is fine in Xcode4, but it gives me a bunch of warnings when I build the project:
Attribute Unavailable
Custom Identifiers in Interface Builder versions prior to 3.2
Is there a way to ignore these warnings in Xcode4? It’s pretty messy when I search for “real” warnings and errors.
Click on your xib file. On the properties you will see the following section:
Where it says “Development” change that to Interface Builder 3.2 and you should no longer receive those warnings.
UPDATE for current iOS Xcode users:
In iOS 4.3 – IB is built into the IDE, and on the right after selecting the xib file there will be some icons, the first icon is called “File Inspector” (looks like a page with a fold in it) that is where the section resides (see below).
