如何扫描hbase中的数值范围(How to scan a numeric range in hbase)

 正如Yan在他的回答中指出的那样，你可以使用标准的BSD风格的网络API，如socket() ， connect()等。但是，如果你想留在Objective C和Foundation，那么你正在寻找NSInputStream和NSOutputStream ，这是Cocoa的流类。 但是，您不应该将NSSocketPort视为专门用于分布式对象。 
 
 Apple的“Cocoa流编程指南简介”在这里： http ： //developer.apple.com/library/ios/#documentation/cocoa/Conceptual/Streams/Streams.html 
 
 您应该从该文档开始，然后查看类引用，这些类引用具有指向使用NSStream及其子类的示例代码项目的指针。 

As Yan notes in his answer, you could use the standard BSD-style networking APIs like socket(), connect(), etc. However, if you want to stay in Objective C and Foundation, then you're looking for NSInputStream and NSOutputStream, which are the stream classes for Cocoa. You should not, however, look at NSSocketPort as that's specifically for use with Distributed Objects.
 
Apple's "Introduction to Stream Programming Guide for Cocoa" is here: http://developer.apple.com/library/ios/#documentation/cocoa/Conceptual/Streams/Streams.html
 
You should start with that document and then check out the class references which have pointers to sample code projects which use NSStream and its subclasses.
