How to wrap BOOL in NSValue

Question

Having trouble wrapping a BOOL value in NSValue.

I tried this:

[NSValue valueWithPointer:[NSNumber numberWithBool:YES]]

Answer 1

An NSNumber is an NSValue subclass. As such,[NSNumber numberWithBool:YES] is already wrapping it in an NSValue for you.

Answer 2

Actually NSNumber is a heavier-weight descendant of NSValue. If you actually want to use an NSValue here's how you'd do that:

BOOL bool_value = YES;
[NSValue valueWithBytes:&bool_value objCType:@encode(BOOL)]
