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"
3
4 @inte易做图ce UIImage (Sprite)
5
6 + (UIImage *)convertSpriteToImage:(CCSprite *)sprite;
7
8 @end
UIImage+Sprite.m
view sourceprint?#import "UIImage+Sprite.h"
@implementation UIImage (Sprite)
+ (UIImage *)convertSpriteToImage:(CCSprite *)sprite {...}
@end
