coco2d教程——sprite与UIImage的转换

+(UIImage *) convertSpriteToImage:(CCSprite *)sprite { 

02         CGPoint p = sprite.anchorPoint; 

03         [sprite setAnchorPoint:ccp(0,0)]; 

04          

05         CCRenderTexture *renderer = [CCRenderTexture renderTextureWithWidth:sprite.contentSize.width height:sprite.contentSize.height]; 

06          

07         [renderer begin]; 

08         [sprite visit]; 

09         [renderer end]; 

10          

11     　 [sprite setAnchorPoint:p]; 

12          

13        return [UIImage imageWithData:[renderer getUIImageAsDataFromBuffer:kCCImageFormatPNG]]; 

14 }

使用CCRenderTexture将CCSprite转化为UIImage，将该函数写成UIImage的类别（catogery）
UIImage+Sprite.h
view sourceprint?1 #import <Foundation/Foundation.h> 

2 #import "cocos2d.h"

4 @interface UIImage (Sprite)

6 + (UIImage *)convertSpriteToImage:(CCSprite *)sprite;

UIImage+Sprite.m
view sourceprint?#import "UIImage+Sprite.h" 

@implementation UIImage (Sprite) 

+ (UIImage *)convertSpriteToImage:(CCSprite *)sprite {...} 

@end
