3G iphone 触摸响应速度比其他设备慢？
我正在为 iPhone 开发一款游戏，我注意到 3G iPhone 特有的差异。我一直在测试 iPhone 的所有 3 个版本 - 2G、3G 和 3GS。 2G和3GS的工作原理相同，但我发现3G上的滑动和触摸响应速度要慢得多。起初我以为这可能只是 CPU 问题，但 2G iphone 速度较慢，而且工作原理与 3GS 相同。
这是一个已知问题吗？ 3G iPhone 是否因触摸灵敏度不同而闻名？
I'm developing a game for the iPhone and I've noticed a difference specific to the 3G iPhone. I have been testing the software all 3 versions of the iPhone - 2G, 3G and 3GS. The 2G and the 3GS work the same, but I find on the 3G that the swipes and touches are much slower to respond. At first I thought it might just be a CPU issue, but the 2G iphone is slower and works the same as the 3GS.
Is this a known issue? Is the 3G iphone known for having a different touch sensitivity?

我建议您重新启动设备并查看其响应是否更快。
我个人并没有感觉到我的游戏应用程序有任何差异。
I suggest you restart your device and see if it is more responsive.
I personnally did not feel any difference in my games applications.
事实证明，这个游戏只是在消耗CPU。当 iPhone 在负载下运行时，触摸性能会下降，使其看起来很粘且响应速度较慢。我已经调整了该应用程序，现在它在所有机器上都可以正常工作。
Turns out the game was just chewing up CPU. When the iPhone is running at load, the touch performance goes down, making it seem sticky and less responsive. I've tuned the app and it now works the same on all the machines.
