Pointer from integer without a cast issue

in my .h file I defined:

BOOL *internetActive;
BOOL *hostActive;

and:

@property(nonatomic) BOOL *internetActive;
@property(nonatomic) BOOL *hostActive;

In my .m file I synthesize them and set the values:

   switch (internetStatus) {
        case NotReachable:{
            self.internetActive = NO;
            break;
        }
        case ReachableViaWiFi:{
            self.internetActive = YES;
            break;
        }
        case ReachableViaWWAN:{
            self.internetActive = YES;
            break;
        }
    }

but I get several warnings. First on every = YES I get

Incompatible integer to pointer conversion to BOOL (aka signed char) from BOOL (aka signed char)

And right after the break statement I get an:

Passing argument 1 of setInternetActive makes pointer from integer without a cast

What does that mean and how do I solve it?

It means that you’ve declared your instance variables/declared properties as pointers to BOOL and you’re using them as plain BOOL. As has been answered already, you don’t want pointers to BOOL. - user557219

If you really want to have a pointer to an object, so you can store them in NSArray/NSDictionary then use NSNumber.

@property(nonatomic, retain) NSNumber *internetActive;
@property(nonatomic, retain) NSNumber *hostActive;

In your *.m

switch (internetStatus) {
        case NotReachable:{
            self.internetActive = [NSNumber numberWithBool:NO];
            break;
        }
        case ReachableViaWiFi:{
            self.internetActive = [NSNumber numberWithBool:YES];;
            break;
        }
        case ReachableViaWWAN:{
            self.internetActive = [NSNumber numberWithBool:YES];;
            break;
        }
    }
