How to make iOS chat instant (real time)? : <p>a part of my app involves building a IM group chat. As right now, I have the whole chat working. However, the problem is that obviously is not instant. It updates in ViewDidLoad(). I know that making it instant is the hardest part in making an IM chat. I'm currently using Parse, and I initially thought of using push notifications to update the page, but Googling a little more I found out that people were saying that there are a few cons in doing that such as the fact that the user would get a crazy number of push notifications. 
Do you have any idea of how could I approach this problem or how I could get my chat to be in real time?</p>

<p>Thanks in advance for the help.</p>
