Title
Body
I have a JSON object that is coming from a webserver. The log is something like this: { "status":"success", "UserID":15, "Name":"John", "DisplayName":"John", "Surname":"Smith", "Email":"email", "Telephone":null, "FullAccount":"true" } Note the Telephone is coming in as null if the user doesn't enter one. When assigning this value to a NSString , in the NSLog it's coming out as <null> I am assigning the string like this: NSString *tel = [jsonDictionary valueForKey:@"Telephone"]; What is the correct way to check this <null> value? It's preventing me from saving a NSDictionary . I have tried using the conditions [myString length] and myString == nil and myString == NULL Additionally where is the best place in the iOS documentation to read up on this?
