How to save textview font, size, color and alignment by NSUserDefaults?

Question

How to allow app users to set font, size, color and alignment an application by custom setting? I am wondering if I can save an UIFont to the NSUserDefaults. How can I get around this issue?

See [this answer](http://stackoverflow.com/questions/1275662/saving-uicolor-to-and-loading-from-nsuserdefaults) for `UIColor`. For the `UIFont` now (since it doesn't adopt the `NSCoding` protocol, you could just keep a string with the font name or a dictionary with the required parameters and pass them to a method that would return a `UIFont` based on those upon retrieval from the defaults. — Alladinian, Jun 02 '13 at 11:47
Have you looked into http://www.cocoacontrols.com There are ton of sample projects that let users choose font colors and change font text or sizes — Sam B, Jun 02 '13 at 12:00

You can create a NSDictionary holding:

Font?

Its PostScript name.

Size?

NSNumber

Color?

NSData (see below)

Alignment?

NSNumber

NSUserDefaults can save NSData. To serialize:

NSData * data = [NSKeyedArchiver archivedDataWithRootObject:color];
[[NSUserDefaults sharedUserDefaults] setObject:data forKey:MONDefaultsKey];

then use NSKeyedUnarchiver to deserialize the NSData representation.

You might also consider saving it as a serialized NSAttributedString if there are associated string(s) -- but that is NSUserDefaults abuse in most cases.
