title: How to mark conversation or message to be unread in a messaging app using ios7 and parse.com?
body: <p>I am building a messaging application for iPhone using Parse as my backend. How can I mark the conversation in the inbox view (not the message view) as there are unread messages here? But I want this the receiver to see it and not the sender... Since push notifications aren't always reliable, I want to find a way to let the user know there is an unread message in some conversation thread.</p>
  
  <p>Any input is greatly appreciated.</p>
  
  <p>EDIT:</p>
  
  <p>I have two classes, one is conversation class which holds an array that points to the messages which reside in messages class. This set up was thankfully suggested by a StackOverflow member a while back.</p>
  
  <p>I have not tried any code to post here... I don't even know how this will work... I am trying to implement a way with my current setup to flag a conversation if it has new messages. I thought about adding a column which indicates new messages inside this thread and based on it I can probably change the cell color in the inbox which has this flag set but then again this will show for both sender and receiver... I want it to show for receiver only and since receiver could be multiple in this case, this is where I am having an issue... It seems like there has to be another class that keeps track of this unless something can be done with the current setup...</p>
