1。不能重复加同一个CCSprite2。ccProgress 不能 淡入淡出

//Left Alignment[gameBeginLabel setAnchorPoint: ccp(0, 0.5f)];// Right Alignment[gameBeginLabel setAnchorPoint: ccp(1, 0.5f)];// Top Alignment[gameBeginLabel setAnchorPoint: ccp(0.5f, 0)];

CGPoint vertex = ccp(_tileSize.width / 2 * _sizeInTiles.width, 0);        CGPoint leftCorner = ccp(vertex.x -  _sizeInTiles.width / 2 * _tileSize.width,                             vertex.

目前的解决办法是在CCDirectorDisplayLink 的startAnimation 方法中 在calculateDeltaTime 方法中 //[displayLink_ addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];   timer_ =  [N

+(CCSprite *) convertImageToSprite:(UIImage *) image {    CCTexture2D *texture = [[CCTexture2D alloc] initWithImage:image.CGImage resolutionType:kCCResolutionUnknown];    CCSprite    *sprite =
