Question

我是目标c世界的新手，并且已经熟悉cocos2d框架。我正在尝试构建一个基本的touchEnabled粒子动画应用程序，它调用子类ccParticleMeteor。我在.m中收到以下编译器错误/警告，我无法重新配置我的代码以消除这些编译器错误。如果需要任何其他说明，请告诉我......谢谢！

`conflicting types for '-(BOOL)ccTouchesBegan:(NSSET *)touches withEvent:(UIEvent *) event'

conflicting types for '-(BOOL)ccTouchesMoved:(NSSel *)touches withEvent:(UIEvent *)event'
Previous Declaration of '-(void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event'
'UITouch' may  not respond to '-LocationInView:'

  emitter.texture = [[CCTextureCache sharedTextureCache] addImage:@"starry1.png"];
               emitter.position = ccp(320, 480);

emitter.position = ccp(point.x, point.y);
return YES;

`conflicting types for '-(BOOL)ccTouchesBegan:(NSSET *)touches withEvent:(UIEvent *) event'
Previous Declaration of '-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event'

这告诉您方法签名不匹配。在这种情况下，它应该是：

-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

换句话说，“touches”方法不会返回BOOL。
