How can I add a boolean value to a NSDictionary?

Question

Well, for integers I would use NSNumber. But YES and NO aren\'t objects, I guess. A.f.a.i.k. I can only add objects to an NSDictionary, right?

Try this:

NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
[dic setObject:[NSNumber numberWithBool:TRUE]  forKey:@"Pratik"];
[dic setObject:[NSNumber numberWithBool:FALSE] forKey:@"Sachin"];

if ([dic[@"Pratik"] boolValue])
{
    NSLog(@"Boolean is TRUE for 'Pratik'");
}
else
{
    NSLog(@"Boolean is FALSE for 'Pratik'");
}

if ([dic[@"Sachin"] boolValue])
{
    NSLog(@"Boolean is TRUE for 'Sachin'");
}
else
{
    NSLog(@"Boolean is FALSE for 'Sachin'");
}

The output will be as following:

Boolean is TRUE for 'Pratik'

Boolean is FALSE for 'Sachin'
