How to retrieve objects from NSMutableArray

Question

I am new to iPhone development. I am parsing XML data and storing its details in a custom object. I have a product class which has product id, product name, etc and I store this in an object. This object is stored in an NSMutableArray.

I want to display the name of each product in a table row. How can I retrieve a particular object name from the NSMutableArray?

Your question would be more clear if you put up some code you have now, but here are some ideas...

Product * product = (Product *)[array objectAtIndex:0]; //this gives you the first product in the array

And maybe...

//print out the name of each product
for (Product * product in array)
{
    NSLog(@"%@", product.name);
}

Note that there’s no need for the (Product *) cast.

Hmm...yea you're right. I think I started doing that because of compiler warnings, but maybe newer compilers don't complain anymore.

You can always assign a value of type id to an Objective-C object variable without a type cast and, conversely, you can always assign an Objective-C object to a variable of type id without a type cast.
