NSHost run in device gives an NSHost.h error

问题

NSHost doesnot support to iphone... When I run this in simulator it works fine... But when I want to run in device means it gives an NSHost.h error....

I want to do this in device also. How could I fix this?

回答1:

NSHost is a private API on the iPhone and is thus not supported on the actual device.

回答2:

Apple have published a technical note (QA1652) on "Using NSStreams For A TCP Connection Without NSHost."

There's a code sample on that page, but here's a summary:

You can do this by exploiting the toll-free bridge between NSStream and CFStream. Use CFStreamCreatePairWithSocketToHost to create CFStreams to the host, and then cast the resulting CFStreams to NSStreams.
