I am making a simple, tilt controlled game using UIKit. So far, when I tilt the device the character moves in the appropriate direction. What I want him to do is to change the direction he is facing when I tilt the device. For example, when I tilt it left, I want the character to face left. Is there a way to detect whether the device was tilted left or right? If so, could you point me in the right direction please. Thanks, Tate

If knowing the actual rotation is good enough for you. Then I would suggest to use an UIViewController and override - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation method
If you need more stuff then I would suggest to do a search about accelerometer

在 John Ray 的名为iOS5 Application Development in 24 Hours的书中，第 18 章说明了使用 CMotionManager 获取加速度计和陀螺仪数据。查看以下网址。您可以下载源代码并加载第 18 章的 ColorTilt 应用程序。它包含有关如何使用陀螺仪信息来确定设备倾斜方向的示例。
