I am trying to set an object's boolean, everything works but I get a

- (void) setActivated: (BOOL *) boolean {
activated = boolean;

The weird thing is that if i setActivated: NO, it would not give any
warning
or error. Only When I setActivated: YES i get this:
"warning: passing argument 1 of 'setActivated:' makes pointer from
integer
without a cast"
Anyone know what's wrong?
Yes. You're trying to make a pointer from an integer without a cast.
Specifically, the pointer is the BOOL* argument to setActivated and
the integer is 1, or -1 or whatever YES is defined is. NO is defined
to be zero, which by the language definition can be assigned to a
pointer without a problem. It's just another name for NULL.
Most likely you don't want 'activated' and the argument to
setActivated: to be pointers.
