Ios 模拟独立手势

我正在做一个游戏，玩家一次移动两个数字。每一个都有它自己的半个屏幕，只在屏幕内移动。不幸的是，我发现当我同时用两个拇指刷卡时，什么也没发生。甚至我的一个识别器都没有被触发

也许有一种方法。我在GameViewController的顶部创建了另外两个视图，并添加了单独的手势。但是我不能在我的游戏场景中引用它们

在GameViewController和GameSene中是否有识别已声明的滑动并向其添加任何操作的方法

我已经试着根据触摸开始和结束来制作我自己的识别器，但是当一次释放两个手指时，它会变得混乱，并且通常会忘记做出两次反应，我的意思是每次释放都是分开的

_侧距=[识别器位置视图：self.view]；
如果（self.sideDisting.x要同时识别多个手势，请在每个手势识别器上设置一个代理。每个手势的代理可以是同一对象

在委托中，执行以下操作：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
     shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    return YES;
}

我想你可以看看这个例子。
这可能对你有帮助

UIScreenEdgePanGestureRecognizer *myScreenEdgePanGestureRecognizer;
...
myScreenEdgePanGestureRecognizer = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(handleScreenEdgePan:)];
myScreenEdgePanGestureRecognizer.delegate = self;
// Configure the gesture recognizer and attach it to the view.
...
 - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    BOOL result = NO;
    if ((gestureRecognizer == myScreenEdgePanGestureRecognizer) && [[otherGestureRecognizer view] isDescendantOfView:[gestureRecognizer view]]) {
        result = YES;
    }
    return result;
 }

最简单的解决方案是将屏幕分为两个次要视图，并在每个视图上附加单独的手势识别器。
我已经这样做了，但没有任何结果。将interface中的delegate和bool设置为YES，您可能还会在每个alloc代码块中看到self.swipgestureDown.delegate=self；行。我认为这会与其他行混淆识别器，比如双重刷卡之类的。（我还没有在代码中声明过这种东西）
