Object at index in NSArray

Question

I have an array. I want to check whether there is an object present in a particular index or not. How to do this? Please help.

Answer 1

if you just want to check if there is an object

if (myIndex < [array count])

if you want to find a specific object

[array indexOfObject:myObject];

if you want to know if the object at some index is of some class

[[array objectAtIndex:myIndex] isKindOfClass:[TheClassToCompareTo class]];

Answer 2

BOOL exists = index < [array count] ? YES : NO;
