ios - cocos2d v3 中带有来自 URL 的图像的 CCSprite

Question

我正在尝试获取 Facebook 个人资料图像，但我无法将从 Facebook 获取的数据转换为纹理，

 NSData *data = [NSData dataWithContentsOfURL:url];
 UIImage *image = [UIImage imageWithData:data];
 NSLog(@"sprite nao existe");
 //convert UIImage to CCSprite
 **CCTexture *texture = [CCTexture textureWithFile:image];**


 CCSprite *sprite = [CCSprite spriteWithTexture:texture];
 sprite.position = ccp(winWidth*.5, winHeight*.5)

在 CCTexture *text... 行中，我收到此警告，这使模拟器停止/崩溃:

Incompatible pointer types sending 'UIImage' to parameter of type NSString

这是日志中模拟器停止时的消息

 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'TextureCache: fileimage MUST not be nil'
*** First throw call stack:

Answer 1

CCTexture *texture = [CCTexture textureWithFile:image];

这里的图像必须是 NSString 而不是 UIImage。 The reference会告诉你的。

改用这个方法:

- (id)initWithCGImage:(CGImageRef)cgImage contentScale:(CGFloat)contentScale

像这样:

CCTexture *texture = [[CCTexture alloc] initWithCGImage:image.CGImage 
                                           contentScale:image.scale];
