ios how to check if object in array in particular index exist? [closed]

Question

I have nsmutable array and I want to add object at particular index, how can I check if the array at particular index has a object or not?

I was doing this:

if ([self.myArray objectAtIndex:index] !=nil) {

but I'm getting exceptions most of the time because "beyond bounds"

I'll really appreciate your help

Answer 1

Easiest (may be not the best) will be

if ([self.myArray count] > index && [self.myArray objectAtIndex:index] !=nil)
