Why not? I find it to be safer than checking for the existence of a method, because you never know if that method might have actually have existed before it went public, but in a less stable form or with different behavior. If this is the case, then just checking whether the method exists and calling it could produce who knows what behavior on older systems. There’s also the case where an API exists, but is buggy on older versions, causing you to want to avoid that API unless you’re running at least a certain version of OS X (for example, -[NSURL URLByDeletingLastPathComponent] before Lion).
