iOS app randomly crashes when scrolling through a table view, not sure how to handle error thrown

Question

All I have is a simple table view that downloads content from twitter using AFNetworking and then displays it in cells. I have paging enabled in my tableView , and sometimes when I scroll between my data on my iPad, my app just freezes and my Xcode screen changes to this:

I am new to Objective-C, but in Java when things like this happened, it wrote out a list of all the methods and line numbers in my code leading up to the crash. Is there any way to get it to do something like that? I don't understand anything about this, and the console is just blank.

Answer 1

Check this question out. It will show you how to determine what is causing the exception.

As with Java, you can also add a try block and their corresponding catch and finally blocks to handle the exception. See this question .

Answer 2

Its because you are using a dictionary in which the object and key at some point of cell is creating problem for you. Check your NSDictionary data.
