Objective C - BOOL cast nil or NO

Maybe dumb question:

NSString *var = @"test";
if (var) {

Here var is casted to BOOL and compared to YES, isn't it ?

Is there any other value that can be transformed to NO when casted to BOOL than nil and NO ?

No, it isn't, why would it?

Any integral expression of value zero does the job.
