In addition to what Yen-Ju already said it should be mentioned that the code 
above would eventually fail anyway. +arrayWithObjects returns an autoreleased 
array, meaning that the resulting array would be gone sooner or later 
automatically and your app would blast.

Concerning categories, be aware that adding a category to NSArray would affect 
_all_ NSArray objects in your app, even those you do not want to use as data 
sources. This does not automatically mean that categories are bad, but simply 
keep it in mind.
