Question

My custom object contains an array of unichar primitives. However there is no encodeUnichar:ForKey method in NSCoder. My solution is to transform my 2d unichar array into an NSString and then encode that.

However, the absence of a method to encode character makes me feel like I am missing something obvious, especially because I couldn’t find the answer on Stack Overflow.

Before I embark on my NSString method, does anyone know if there is a simpler way to do this built in into the NSCoding protocol?

Thanks
Lee.

A C array of fixed-size data is best encoded using encodeBytes:length:forKey:. See Encoding and Decoding C Data Types for full details.
