NSArray becomes NSCFArray when passed

Question

I have a method that receives many different kinds of objects and decides what to do with them:

-(void)performAction:(NSObject *)myAction withItem:(Item *)my         


        

Answer 1

NSСFArray is subclass of NSMutable Array

You can use isKindOfClass to check it

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 isKindOfClass:[NSArray class]] ) {
        NSLog(@"--- CUSTOM ACTION --- %@", myAction);
        currentActionArray = (NSArray *)myAction;
}
