I have a number of NSString objects I want to save into an NSDictionary.
How is an NSDictionary initialized with the keys and do the values need to be set there and then or can the dictionary be setup using just the keys and the objects later set?
A dictionary can be initialized both as empty or as a list of
(value,key)pairs.Initializing the dictionary just with keys and not values is useless/meaningless in Objective-C, since it will be equivalent to a void initialization.
If you want to create a dictionary and want to be able to set objects later, you have to use a
NSMutableDictionary, that has not a static initialization of its data, through itssetObject:forKey:method.
