ios - Parse.com data caching and synchronization - what best strategy synchronize parse objects across application? take twitter example, have many tweet objects, same tweet object can shown on multiple places, viewcontroller1 , viewcontroller2, not efficient both of them hold deep copies of same parse object. when increment likecount of tweet_168 in viewcontroller2, how should update likecount of tweet_168 in viewcontroller1? i created singleton container class (tweetcontainer) every parse request goes through , checks if incoming objectids in container, a) if is, updates previous object's fields , dumps new object. (to maintain single deep re-create of parse object.) b) if not, adds new object. (this process fast i'm using hashmaps) this container holds deep copies objects, , gives shallow copies viewcontrollers, editing tweet in viewcontroller result in update on viewcontrollers! taking 1 step further, let's tweet objects have pointers author objects. w
