Java中的“Buffer”类是否有任何Objective-C等价物？

Question

I am trying to find any equivalent class or library for the "Buffer" object in Objective C. Here is the documentation of the "Buffer" class in Java: http://docs.oracle.com/javase/1.4.2/docs/api/java/nio/Buffer.html I need it in objective-C. Thank you.

Answer 1

NSData and its mutable subclass NSMutableData provide data objects, object-oriented wrappers for byte buffers. Data objects let simple allocated buffers (that is, data with no embedded pointers) take on the behavior of Foundation objects.
