Question

I’m using a conditional statement such as

// isComplete is a BOOL value
if (![videoDictionary valueForKey:@"isComplete"]) {

    // do important things here

}

The problem is that this statement doesn’t seem to be able to differentiate between NO, nil, and key doesn’t exist. How can I make sure that this condition is met ONLY when isComplete is NO, and not when isComplete is nil or isComplete doesn’t exist (no key)? How do I stop the false positives?

Answer 1

Do something similar to this:

NSNumber* IsComplete;
IsComplete=[videoDictionary objectForKey:@"isComplete"];
if (IsComplete!=nil && ![IsComplete boolValue])
{
   ...
}
