Re: NSLogging a memory address

How can I get NSLog() to output the memory address that a given pointer is pointing to?

NSLog(@"%@<%x>", object, &object);

doesn't seem to work, as the area in brackets is not the same as the memory address displayed in the debugger. I know that I've seen this done, and I know that NSObject does it, but I can't remember the magic to do it.

In the above object is already a pointer, actually in general you cannot have Objective-C objects allocated on the stack. So you are always working with pointers if you are dealing with an Objective-C object. In other words no need to get the address of it because it is already an address.

I would use the following...

NSLog(@"%@ <%p>", object, object);

Using %p will insure that if the size of pointers change your output code will still be happy, at least in theory.
