Hi Daniel,
You are not returning a created object but a reference
to a Singleton class. You should do:
return uniqueInstance;
and not
return self.
Read on class and instance methods in ObjC reference
book on Apple's site.

Gorazd
static Singleton *uniqueInstance = nil;
@implementation Singleton
+ (Singleton *) getInstance {
if (uniqueInstance == nil) {
uniqueInstance = [[self alloc] init];
[uniqueInstance setValue: 0];
}
return self;
}
- (void) setValue: (int) newVal {
value = newVal;
}
- (int) value {
return value;
}
