   @interface Class1 : CCNode {
   
        CCSprite *friPanSprite ;
   
   }
   @property (nonatomic,copy) CCSprite *friPanSprite;
   
   @end

   class1.m

   @implementation Class1
   
   @synthesize friPanSprite;
   
   @end

   so when i do this in main
   

   CCSprite *lable = [CCSprite spriteWithFile:@"test.png"];
     Class1 *objclass = [[Class1 alloc]init];
     objclass.friPanSprite = lable;

   to avoid problem like this, if you use friPanSprite in the same .m file you don't need to declare @property.
   Let xcode handle that for you.

   CCTexture2D *tx = [mySprite1 texture];
   CCSprite *mySprite2 = [CCSprite spriteWithTexture:tx];

   if you need a full copy of some object you can try this:

   @interface YourClass : NSObject <NSCopying>
   {
   SomeOtherObject *obj;
   }

   // In the implementation
   -(id)copyWithZone:(NSZone *)zone
   {
   // We'll ignore the zone for now
   YourClass *another = [[YourClass alloc] init];
   another.obj = [obj copyWithZone: zone];

   return another;
   }

   CCTexture2D *tx = [mySprite1 texture];
   CCSprite *mySprite2 = [CCSprite spriteWithTexture:tx];

   by this it only get the image of the sprite not all the attribute of the sprite like where is place what is the scale or many other and
   

   @interface YourClass : NSObject <NSCopying>
   {
   SomeOtherObject *obj;
   }
   
   // In the implementation
   -(id)copyWithZone:(NSZone *)zone
   {
   // We'll ignore the zone for now
   YourClass *another = [[YourClass alloc] init];
   another.obj = [obj copyWithZone: zone];
   
   return another;
   }

   this is only for that class which i created this is not work for the sprite so any other option

   You never EVER create member data outside the class. That is what OOP is all about. Encapsulation.
   In case you need your class to create a clone, make a method that clones the input.
   

   [ objclass cloneSprite:lable ];
