问题
I tried to add an NSHost method and XCode didn't recognize it.
Do you know why this happened?
回答1:
Your question is tagged with iPhone; NSHost is not available on the iPhone. NSHost is Mac OS X only.
Here is an alternative solution to using NSHost: Alternatives to NSHost in iPhone app
回答2:
NSHost is not supported for iPhone. Read apple's technical note

iPhone SDK does not support NSHost. But you can use this alternative Objective-C custom class instead.
