How do I create instance of NSHost from IP address?

Apologies- i'm new to xcode/cocoa/objective-c...

I'm struggling to understand what is wrong with:

NSHost *host = [NSHost hostWithAddress:@"192.168.0.155"];

I'm receiving 2 errors"

No known class method for selector 'hostWithAddress:'
Receiver 'NSHost' for class message is a forward declaration

Could you help explain the errors and how I can achieve the simple task of creating an instance of NSHost pointing to 192.168.0.155.

Thanks

Lee

As mentioned NSHost is not available in iPhone, depends on what you need it for you could bypass it by using this sample code by apple: https://developer.apple.com/library/ios/qa/qa1652/_index.html

It turns out NSHost is not available on the iPhone! It's a shame xcode didn't highlight that for me!

I tried to use NSHost and XCode didn't recognize it

Thanks for your help,

According to the documentation for NSHost, you are using exactly the right method. However from looking at your error message, it says hostwithAddress, the correct casing is hostWithAddress, so make sure there is a capital W.

Also, make sure you have #import <Foundation/Foundation.h> at the top of your .m file.

Remember, Objective-C is a case sensitive language.
