I have an NSMutableArray returning an extremely large index?
po [masterArray count] < returns \"2\"
NSUInteger theIndex = [masterArray indexOfObject:valida
That's the value for NSNotFound. This means the object you are looking for isn't in the array.
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);
}
