Doesn't look weak to me.

Leftover from old implementation. Good catch!

Done.

IBOutlet is an empty macro which says "Hey, Interface Builder, this is an
outlet."  It needs to be on the instance variable, and is not necessary here.

Actually, I don't even think you need these @property lines unless you intend to
access the member variable from outside the class.  You might have to change
cases like self.iconView to iconView in your implementation file.

Still use nameField outside, so I left it. Took out the non-needed stuff.

Done.

This seems like it could be one line?

[beaudoin, 2012/10/13 00:20:55]

By moving the IBOutlet it now fits!

Done.
