如果你想在不使用OpenGL的情况下这样做，你可以使用UIImageView并设置一系列动画图像。通过创建一系列图像，您可以创建“滚动骰子”效果。以下是如何执行此操作的示例：

// create a UIImageView
UIImageView *rollDiceImageMainTemp = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"rollDiceAnimationImage1.png"]];

// position and size the UIImageView
rollDiceImageMainTemp.frame = CGRectMake(0, 0, 100, 100);

// create an array of images that will represent your animation (in this case the array contains 2 images but you will want more)
NSArray *savingHighScoreAnimationImages = [NSArray arrayWithObjects:
                                                [UIImage imageNamed:@"rollDiceAnimationImage1.png"], 
                                                [UIImage imageNamed:@"rollDiceAnimationImage2.png"], 
                                                nil];

// set the new UIImageView to a property in your view controller
self.viewController.rollDiceImage = rollDiceImageMainTemp;

// release the UIImageView that you created with alloc and init to avoid memory leak
[rollDiceImageMainTemp release];

// set the animation images and duration, and repeat count on your UIImageView
[self.viewController.rollDiceImageMain setAnimationImages:savingHighScoreAnimationImages];
[self.viewController.rollDiceImageMain setAnimationDuration:2.0];
[self.viewController.rollDiceImageMain.animationRepeatCount:3];

// start the animation
[self.viewController.rollDiceImageMain startAnimating];

// show the new UIImageView
[self.viewController.view addSubview:self.rollDiceImageMain];

您可以根据需要修改创建和设置，包括大小，位置，图像数量，持续时间，重复计数等。我已经使用UIImageView的这个功能来创建简单的动画效果，效果很好！

如果您尝试这个并且它是否适合您的需要，请告诉我。另外，发布任何后续问题。

很好你的例子，但你认为用触摸手势旋转/控制旋转是否可能？
