I am new to objective-c, I am doing the same app for android and iPhone.
When in Java I use a try-catch block to catch a network exception and handle it.
In Objective-C I am using:
[[NSXMLParser alloc] initWithContentsOfURL:url]
So, How can I handle a network exception when parsing that input stream, so if network goes down or there's any problem I can notify user and keep my app working?.
