无论如何，当我的游戏在 iPhone 上运行时，我可以通过捏缩放来为我的游戏工作吗？

我使用 Stencylworks 为一个班级项目制作了游戏。该游戏在 iPad 上运行完美，也可以在 iPhone 上运行，只是场景被放大了，这使得玩起来非常困难。

有没有办法实现缩小的捏合手势？也许可以在 Xcode 中使用视图控制器或在某处添加代码来完成？我是 Xcode 的新手，所以我完全不知道如何让它工作！

不确定这是否会有所帮助，但这里有一些项目的屏幕截图。

如果您使用的是 iOS 3.2 或更高版本，请在 Viewdidload 中添加以下代码。并在 .h 文件中添加 UIGestureRecognizerDelegate

//Gesture reconizer
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(checkpinch)];
[pinch setDelegate:self];
[pinch setDelaysTouchesBegan:YES];
[self.view addGestureRecognizer:pinch];
[pinch release];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(checktap)];
[singleTap setDelegate:self];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired =2;
[self.view addGestureRecognizer:singleTap];
[singleTap release];


UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(checktap)];
[doubleTap setDelegate:self];
doubleTap.numberOfTapsRequired = 2;
doubleTap.numberOfTouchesRequired =1;
[self.view addGestureRecognizer:doubleTap];
[doubleTap release];


// Gesture Reconizer Methods
-(void)checkpinch {    

    //write here code for your requirements
}

-(void)checktap {

    //write here code for your requirements
}

我希望这会帮助你......冷静
