NSMutableArray indexOfObject returning an extremely large number

Question

I have an NSMutableArray returning an extremely large index?

po [masterArray count] < returns "2"

NSUInteger theIndex = [masterArray indexOfObject:validateEnrollmentStatus];

The above returns an NSUInteger of "2147483647"? I am not sure how that is possible or what is going on? masterArray clearly on has to item in given the count method call in the debug console.

Anyone have any suggestions?

Answer 1

That's the value for NSNotFound. This means the object you are looking for isn't in the array.

Answer 2

Try it like this. validateEnrollmentStatus is not present in masterArray. So you can probably add a check for that before you try to get the indexOfObject.

    NSUInteger theIndex = 0;

    if ([masterArray containsObject:validateEnrollmentStatus]) {
        theIndex = [masterArray indexOfObject:validateEnrollmentStatus];
    } else {
        NSLog(@"%@ is not present in masterArray", validateEnrollmentStatus);
    }
