回答1:
There are two changes you need to make in order to use this:
- Change
#import <Cocoa/Cocoa.h>to#import <UIKit/UIKit.h>(You could probably get away with using<Foundation/Foundation.h>, too) - Try to compile again. You'll get errors about an unknown symbol "pi". Change the three occurrences of those to
M_PI(the constant defined in<math.h>for π).
You'll still get warnings (about deprecated methods), but it will compile and work.

If you have UI classes, then you will need to remove them (as you noted you have). If you have non-UI classes importing Cocoa.h, they generally shouldn't be (AppKit, which is implemented in Cocoa.h, is mostly UI). Replace Cocoa.h with #import <Foundation/Foundation.h>. If they actually rely on things in Cocoa.h, then you have porting work to do.
