Ok, I think I understand this after reading this document:
http://developer.apple.com/mac/articles/cocoa/managingconcurrency.html
So to make it clear, I invoke the method as an NSInvocationOperation then in
the method I do this whenever I need to access the mutable dictionary:
- (void)doResourceHungryTask {
...
@synchronized (myDictionary) {
[myDictionary setObject:anObject forKey:@"testKey"];
}
}
Is that correct?
