Question

I have the following declaration in my class called GameManager:

-(void)playBackgroundTrack:(NSString*)trackFileName isAmbient:(BOOL*)ambient {

}

I want to be able to call

[[GameManager sharedGameManager] playBackgroundTrack:BACKGROUND_TRACK isAmbient:NO];

or

[[GameManager sharedGameManager] playBackgroundTrack:BACKGROUND_TRACK isAmbient:YES];

but I am getting a warning:

Semantic Issue: Instance method ‘-playBackgroundTrack:isAmbient:’ not found (return type defaults to ‘id’)

and trying to use the isAmbient parameter crashes.

it works ok if I leave the isAmbient declaration off in both places (but of course I can’t use the parameter I want!).

Answer 1

You should use plain BOOL, not BOOL* in the declaration, like this:

-(void)playBackgroundTrack:(NSString*)trackFileName isAmbient:(BOOL)ambient;
