Question

I have a NSMutableArray:

NSMutableArray *temp = //get list from somewhere.

Now there is one method objectAtIndex which returns the object at specified index.

What I want to do is that, I want to first check whether an object at specified index exists or not. If it exists than I want to fetch that object. Something like:

if ([temp objectAtIndex:2] != nil)
{
     //fetch the object
}

But I get exception at the if statement saying that index beyond bound.

Please anyone tell me how to achieve this.

Answer 1

you cannot have ’empty’ slots in an NSArray. If [myArray count]==2 ie array has two elements then you know for sure that there is an object at index 0 and an object at index 1. This is always the case.
