There is no direct way to reinitialize a view, unless you are dealing with a case where you can remove it entirely and recreate it by reloading the nib file.

In this case, you just want to call setHidden:NO on all of the buttons. Something like:

for (NSView *subview in [[[myTabView tabViewItemAtIndex:0] view] subviews])
    [subview setHidden:NO];
