doubleTapRecognizer_ = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];
    doubleTapRecognizer_.numberOfTapsrequired = 2;
    doubleTapRecognizer_.cancelsTouchesInView = NO;
    [[[CCDirector sharedDirector] view] addGestureRecognizer:doubleTapRecognizer_];

我有这个类的多个实例,但唯一一个获取它的选择器的实例是添加的最后一个实例. UIView Class Reference让我相信可以在单个视图中添加多个UIGestureRecognizer.属性“gestureRecognizers”返回NSArray.

事实上,我已经有一个UIPanGestureRecognizer使用来自另一个类的相同视图.所以我得到至少两个UIGestureRecognizer一次工作.
