A question about textureForKey.
Question code :

CCImage *img = new CCImage;

img->initWithImageData( rawData, width*height, CCImage::kFmtRawData, width, height );

CCTexture2D* tex = CCTextureCache::sharedTextureCache()->addUIImage( img, "catImage" );

if( CCTextureCache::sharedTextureCache()->textureForKey( "catImage" ) ) {

// find

}
else {

// oh...no

// it run here

}

textureForKey don't find "catImage".
maybe I use way is wrong ?

Thank you.

Thanks for your feedback!
Yes, it's a bug of engine! Issue #750 created for it.

The reason of this bug had been discussed in this topic:
http://www.cocos2d-x.org/boards/6/topics/2653?r=2982#message-2982

And we only can fix this bug by modify the key with method CCFileUtil::fullPathFromRelativePath() when CCTextureCache::addUIImage() invoked.

Best wishes!

Yes.
Woods Lin, you can add CCFileUtil::fullPathFromRelativePath() in CCTextureCache::addUIImage(), and do a test.
Share the result is better.

thanks for help me.

And test is ok, I can get the CCTexture2D object.
but the way isn't my think result.

because I own one file call "imageObject.data",then it own many images in the data.

so I do:

// save the memory

loadImageFile( "imageObject.data" );

// get image from 0 index

BYTE *rawData = getImageFromIndex( 0 );

CCImage *img->initWithImageData( rawData, width*height, CCImage::kFmtRawData, width, height );

CCTexture2D* tex = CCTextureCache::sharedTextureCache()->addUIImage( img, "imageName_1" );

// get image from 1 index

BYTE *rawData2 = getImageFromIndex( 1 );

CCImage *img2->initWithImageData( rawData2, width*height, CCImage::kFmtRawData, width, height );

CCTexture2D* tex = CCTextureCache::sharedTextureCache()->addUIImage( img2, "imageName_2" );

but now "imageName_1" and "imageName_2" can't so use, i must name it call "imageObject.data".
because these images separated to memory address, then they don't have separated to many files in the hard disc.

May give me some suggestions?

thanks.
