我在Objective-C中遇到一些奇怪的编译器错误:

 iBody.h:18: error: ISO C++ forbids declaration of 'iObject' with no type

   #import "iElement.h"
   #import "CCSprite.h"
   #import "iBody.h"

   @interface iObject : iElement
   {
       iBody *body;
   }

    -(iObject*)initElement:(CGPoint)pos
          withName:(NSString*)name
            zIndex:(NSInteger)z
         withImage:(NSString*)image;

    -(void) addBody: (iBody*) body;
    -(iBody*) getBody;

 @end

  #import "iObject.h"
  #import "b2Body.h"

  @interface iBody : NSObject
  {
      CGPoint position;
      float angle;
      b2Body *body;
      iObject *parent;
   }

    -(iBody*) initElement: (CGPoint) pos
        withAngle: (float) angle
       withParent: (iObject*) el;

    -(void) setBody: (b2Body*)bdy;
    -(iObject*) getParent;

   @end

最佳答案

好像您正在导入循环中，因为iBody和iObject的 header 相互链接。通常，在这种情况下，我会认为iObject的状态更高，并在iBody.h中使用以下内容:

// Replace the import to iObject.h with this:
@class iObject;

// Add the import back in iBody.mm
#import "iObject.h"
