Question

Something is wrong, this code

if ([g count] >= 1) {
     NSLog(@"%@", [g objectAtIndex:1]);
}

Keeps generating this error

reason: '*** -[__NSArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0]'

Unless I’m going crazy, this shouldn’t happen, right?

The code is NOT multithreaded at this point and I’m working off a simple array. If I NSLog the g.count, i get a value of 1.

EDIT: I have also tried

if ([g count] > 0) {
     NSLog(@"%@", [g objectAtIndex:1]);
}

and get the same error.

Answer 1

When count is 1, it means that you can use index zero. Index of 1 is not valid.

In general, only indexes from zero to count-1, inclusive, are valid.
