Question

Say I have a property list that I store into an NSDictionary. An example output from NSLog follows:

2010-12-05 15:26:26.631 TestApp[598:207] Test contents: {
Address = "";
Name = "Test Dictionary";

What exactly would the value for Address be considered? I have heard many possibilities, but I’m not sure exactly. Is it NSNull, nil, what? What I would ultimately like to do is to create a second NSDictionary that filters out all of these blank values, as seen here. But first, I need to figure out what the blank value is counted as, so then I can parse my plist for them, and then discount the keys associated with them.

Answer 1

An empty string is a string, not NSNull or nil. So one way to test would be [@"" isEqualToString: thevalue].
