I wonder if Objective-C offers support for Lists? Or .. is NSMutableArray a way to go, instead?
Yes
NSMutableArray(Mac, iOS) would in most cases be the appropriate class for lists (withNSArraybeing the immutable counterpart).Contrary to Java’s collection classes Objective-C‘s (or rather Foundation‘s) arrays are opaque class clusters that completely hide their implementation.
Edit: snip (see comment by orange80)
While Java has a ton of collection classes such as:
HashSetTreeSetLinkedHashSetArrayListLinkedListPriorityQueueHashMapTreeMapLinkedHashMapWeakHashMapIdentityHashMapCopyOnWriteArrayListCopyOnWriteArraySetEnumSetEnumMapConcurrentLinkedQueueLinkedBlockingQueueArrayBlockingQueuePriorityBlockingQueueDelayQueueSynchronousQueueConcurrentHashMapObjective-C however (again, actually the Foundation SDK) only provides a very limited number of collection classes:
CFMutableDictionaryCFMutableBagCFMutableBitVectorCFMutableSetCFMutableArrayCFBinaryHeapCFMutableTreeor preferably their NS-equivalents:
NSMutableDictionaryNSDictionaryNSMutableSetNSSetNSCountedSetNSMutableArrayNSArrayFor a full insight in the matter I recommend this read:
