Assignment makes a pointer from a whole without a role

Question

I have an Obj-C method like this:

-(void)getUserDefaults:(BOOL *)refreshDefaults
{
    PostAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];

    if (refreshDefaults) {
        [appDelegate retrieveDefaults];
    }
}

When I call it that, I get no warning:

[self getUserDefaults:NO];

When I call this, I get a warning:

[self getUserDefaults:YES];

warning: passing argument 1 of 'getUserDefaults:' makes a pointer from an integer without cast

NOTE. I always call the method that passes NO first, and then passes YES after a while

Can someone fill me with the fact that the problem is here? Thanks.
