just type id before the variable name.

whenever you're declaring a variable you always start with the data type first for example.

NSString *string; NSArray *array; int score;

and so forth.

well in your case, declaring of type id, you don't need to use a pointer(*). but to answer your question, yes you just declared a variable name thing with the type id and initialized it to nil.
