I have a method that receives many different kinds of objects and decides what to do with them:
-(void)performAction:(NSObject *)myAction withItem:(Item *)myItem {
actionCount = -1;
NSLog(@"-- NEW ACTION ARRAY --");
if ([myAction isMemberOfClass:[Look class]]) {
currentActionArray = [self createLookArray:(Look *)myAction item:myItem];
} else if ([myAction isMemberOfClass:[Use class]]) {
currentActionArray = [self createUseArray:(Use *)myAction item:myItem];
} else if ([myAction isMemberOfClass:[Exit class]]) {
currentActionArray = [self createExitArray:(Exit *)myAction item:myItem];
} else if ([myAction isMemberOfClass:[NSArray class]] ) {
NSLog(@"--- CUSTOM ACTION --- %@", myAction);
currentActionArray = (NSArray *)myAction;
}
[self performNextAction];
}
One of four things is going to come through here: Look, Use, Exit or NSArray. The first three are sent off to become NSArrays, the last is already an NSArray.
Now, when I do pass an NSArray in here from elsewhere, like this:
NSArray *myAction = [[NSArray alloc] initWithObjects:myAction1, myAction2, nil];
[controller performAction:myAction withItem:nil];
...the custom action is never called, because it reads myAction as an NSCFArray rather than an NSArray. When I try [myAction isMemberOfClass:[NSCFArray class]] it doesn't recognise the CF. The simple way to get it working at the moment is just to assume that anything not a Look, Use or Exit is an NSArray (get rid of the last else if, and just leave it as an else), but that seems sloppy to me.
Anyone know how I can deal with this?
Thanks, -k.
