Possible Duplicates:
What's your preferred pointer declaration style, and why?
Placement of the asterisk in Objective-C

Is there any difference between

NSString* foo = @"I'm a string";

and

NSString *foo = @"I'm a string";

I’ve always used the latter way, but wasn’t sure if there actually was a difference.

Thanks!

No. There is no difference at all. It’s the same as in C language. They are both pointers to NSString.

Some people prefer the later form because it makes clear what variable is the pointer. I.E.:

int* i, j;
// i is a pointer
// j is not a pointer

int *i, j;
// makes clearer that i is a pointer while j is not

int *i, *j; // both pointers...
