Hi, Is it best to have static constructors where you alloc the instance in the constructor and you return the instance as auto release, e.g. [String stringWithFormat...] or is it best to have dynamic constructors where you ask the user to alloc first so that he is in charge of releasing? When should you use each? Cheers ...
I'm writing an app, that automatically finds peers running the same app, so I need the Bluetooth-device. But because of app-restrictions I'm not allowed to use the private framework to enable, or activate the Bluetooth-device.

I don't have my C book to hand, but I note ...

Is this even p...

In the Xcode documentation for NSCopyObject, the special considerations section states: This function is dangerous and very difficult to use correctly.
