Objective C decodeBoolForKey not compatible with BOOL

So I have an NSObject which implements NSCoding. In my decoder method it needs to retrieve a BOOL that belongs to the class among other properties.

-(id)initWithCoder:(NSCoder *)decoder {
    self = [super init];
    if (self) {
        [self setRandomObject:[decoder decodeObjectForKey:@"randomObjectKey"]];
        [self setMyBool:[decoder decodeBoolForKey:@"myBoolKey"]];
    }
    return self;
}

This however throws the following warning on the line with [self setMyBool ... (Yellow warning, still runnable).

Incompatible integer to pointer conversion sending 'BOOL' (aka 'signed char') to parameter of type 'BOOL *' (aka 'signed char *')

I don't understand why it is trying to send a pointer of a bool to a bool. If anyone knows how this can be fixed please let me know! Thanks a ton.

Also, it's very late right now, and me being exhausted, I may have just missed something simple so please bear with me.

So it appears I accidentally declared the property as a BOOL * instead of a BOOL. I changed it and everything works now. After reading the comments and answers I decided that the method was correct, then looked at the declaration of the property. Thank you very much, coding late at night is harder than I thought.

Does your method look like this?

- (void)setMyBool:(BOOL *)value
or:
@property BOOL *myBool;

Because it should be:

- (void)setMyBool:(BOOL)value
or:
@property BOOL myBool;
