Re: basic Obj-C lesson (was runtime error with NSArray no more!)

Is that the array you created with arrayWithObjects:? If so, that method returns an autoreleased object. An autoreleased object normally only exists for the lifetime of the event (in this case, the awakeFromNib: event) in which it was created.

so are you saying that on my first iteration I should add something like [[myArray objectAtIndex: i] retain]; and then of course release it after the second iteration?

that makes a good deal of sense. man, I'm used to C and C++ I don't know how long it will take to get used to this memory management scheme. In this specific instance I'm not sure I understand how the NSButton object is created and destroyed. I mean its in my UI but you're saying that that the object is only retained as long as the call is going on? Shouldn't the pointer in my NSArray still point to the object that exists in the UI? I would love to hear the answer to this, thanks.

cool runnings,
