Question

What is the best was to determine if an NSString is empty? Right now I am using the following:


if (string == nil || [string isEqualToString:@""]) {
// do something }


Thanks for any advice.

Answer 1

if ([string length] == 0) {
    // do something
}

If the string is nil, then the message to nil will return zero, and all will still be well.
