This question has come up during the last CocoaHeads and no one was
really able to give a definite answer.
Do both expressions really mean the same thing (as nil is not null)?
if (!foo) {
...
}
if (foo == nil) {
...
}
Just try it out in a small project...
Keep in mind that Objective-C is the same as C, and C only checks for
numbers within the if() statement...
0 = false, 1 or more = true...
nil = 0 so, they mean the same thing...
cheers
