Question

如何让uiview能把touch事件向下传递，像cocos2d的swallow一样

Answer 1

在根视图定义个手势
UITapGestureRecognizer *tapGesture=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction)] ;
tapGesture.delegate=self;
[tapGesture setNumberOfTapsRequired:1];
[self.view addGestureRecognizer:tapGesture];

-(void)tapAction
{
NSLog(@"tap");
}

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{
if ([touch.view isKindOfClass:[UIView class]]) {
[self tapAction];
return NO;
}
return YES;
}

就可以了

Answer 2

你好
写个delegate，让响应的view自己去实现响应方法
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event{

if (xxxxx) {
return TRUE;
}

return FALSE;
}

这个方法可以解决
只要return FALSE就相当于忽略掉点击事件...
每个点击会先调用这个方法后才会调用touch系列方法
