What does the compiler say?
Not tried this, but as BOOL is neither a pointer nor subclass of
NSObject, I would not expect reliable results, but a type mismatch.
Of course, I could be wrong, YMMV.

Suppose I have an object with a declared method signature:
-(void)myMethod:(BOOL)a_bool;
Q1: If I invoke it like this:
[self performSelector:@selector(myMethod:) withObject:nil]; // nil
obj
Will argument a_bool end up with a 0 value assigned to it?
Q2: But if I invoke it like this:
[self performSelector:@selector(myMethod:) withObject:someObj]; //
valid obj
Will argument a_bool end up with a 1 value assigned to it?
