有没有办法将任何对象的内存地址作为NSString？

Question

I need to store the memory address of an Object as an NSString. Is there a special format specifier for that?

Answer 1

%p should work for any pointer, including pointers to objects. So:

NSString *addr = [NSString stringWithFormat:@"%p", obj];

That will be a string beginning with 0x and in hexadecimal.

Answer 2

Yes, you can use the %p formatter to get the address of an object as a string. Something like this would work:

NSString *pstr = [NSString stringWithFormat:@"%p", myPtr];
