try/catch really should be avoided in all but the most extreme cases. Apple have a great API for handling situations where known errors will occur by usually including an NSError parameter in the message invocation or delegate callback. try/catch are not the usual mechanism for error handling but are used in extreme situations where you will usually abort your app anyway. I would encourage you to rethink your application design and use the standard means of error handling before resorting to try/catch.

+1. I think it's particularly tempting for Java/C# developers to get started down the wrong path with this stuff.
In cocoa you may want to understand why Exception Happening and have to solve the situation more then Handling that..Any way you can use
@try
{
//Your code
}
@catch(NSException* e) // or subclass of NSException
{
}

It's important to know that the semantics of the exception handling on ObjC is different to some other languages, such as C#, and great care must be taken to ensure that all objects are released properly. I suggest either using GC, or using autorelease pools extensively. (Or both!)
