问题 I'm wanting to display money like SWOS (or Sensible World of Soccer) used to. IE: Instead of: $10,000,000+ you got $10m, 10.5m, etc. Instead of: $1,000,000 you got $1m Instead of: $1,500,000 you got $1.5m It also worked for both large and smaller figures, say; 1k, 1.25k, 0.75k, 0.25k, etc. I'm wondering, is there a way to display money in a format that is similar to the way SWOS used to do it? Thanks. 回答1: You can do this by writing a subclass of either NSFormatter or NSValueTransformer,

问题 What I need is custom format to change values according to these rules: If "/" is absent and number's length is less than 6, add zeroes to the begining. If "/" is present and number's length before"/" is less than 6, add zeroes to the begining. If "/" is present and number's length after "/" is 1, add zero before last character. If "/" is present and number's length after "/" is 2, leave as it is. Total length of string with "/" would be 8, without it - 6 Unformatted data: -534 1083 386840/2

问题 I've setup TFS notifications for when a Build Breaks and it works but the email is malformed and full of Asian characters: I'm assuming there is a locale setting causing it? I don't have access to the SMTP server but its unlikely anyone else is encountering malformed messages. Does anyone know what causes this and how to fix it? 回答1: I logged my very first Microsoft case for this one, brings back memories . Solution 1 The MSFT Engineer found a similar case: TFS Notifications and alerts are
