CCLabelTTF 移动闪动bug

#1

iOS 上 使用CCLabelTTF制作走马灯效果文字狂闪，主要设备是iphone5 iphone5c ipad上。 不知道什么原因。

不好意思 是没描述清楚。

补充 ：是2.2.1版本 iphone4 上 是好的 测试机器少无法覆盖更多机型。

#2

什么版本 如果是2.1.3的话 是有这个bug 是ccimage里面 initWithXXXX什么的里 w h 是浮点数的原因造成的 强转成int就行了

不好意思 是没描述清楚， 请看我补充回复。

2.2.1版本，楼主麻烦提供下代码。:14::14::14:明早给您测试。

我用你的代码在3.0 rc1删跑了一下，没有问题啊。

我的开发环境是2.2.1 3.0的还没跑过。
