捏到變焦iPhone

Question

是否有反正我可以捏縮放工作爲我的遊戲，當它在iPhone上運行？

我使用Stencylworks製作了一個類項目的遊戲。遊戲在iPad上運行完美，並且在iPhone上運行，除非場景放大，這使得玩起來非常困難。

有什麼辦法可以實現縮小手勢嗎？也許它可以在視圖控制器的Xcode或在某處添加代碼完成？我是Xcode的新手，所以我完全不知道如何讓它工作！

不確定這是否有幫助，但這裏是項目的一些屏幕截圖。

如果您使用的是iOS 3.2或更高版本比你viewDidLoad中添加以下代碼。而在.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 
} 

我希望這將幫助你放鬆...
