CupByteCountTransformer
This class is a CPValueTransformer that converts numbers into formatted byte counts by using a CPByteCountFormatter. For information on how byte counts are formatted, see the Apple documentation.
By default this class uses a shared formatter with the following properties:
- adaptive: YES
- allowedUnits: CPByteCountFormatterUseKB | CPByteCountFormatterUseMB | CPByteCountFormatterUseGB
- allowsNonNumericFormatting: NO
- zeroPadsFractionDigits: YES
If you want to change the properties of the shared formatter, you can retrieve it with the +sharedFormatter method.
If you want to change the properties of the formatter for a specific transformer instance, you can either create a new CPByteCountFormatter yourself and use the -setFormatter: method, or use the -formatter method, which will return a new instance of CPByteCountFormatter that belongs to the transformer instance. You can then set the properties of the returned formatter as you wish.
Returns the shared CPByteCountFormatter used by default by all instances of this class.
Returns the receiver's instance of CPByteCountFormatter. If the receiver does not yet have its own formatter, a new CPByteCountFormatter is assigned and then returned.
Sets the formatter used by the receiver. If aFormatter is nil, the shared formatter will be used when transforming values.
