What is “->” in Objective C?

what is the "->" in objective-c? And what is it used for?

It's the same as in C. Objective-C is a strict superset of C, so it inherits all the syntax. In C:

x->y

is the same as:

(*x).y

The syntax *x dereferences the pointer x, and . accesses a property on the result of the dereferencing.

-> is for Accessing instance variables (Pointers)
