ios - 检测UIScreenEdgeGestureRecognizer并使UIPanGestureRecognizer失败

在我的ViewController中，我有一个用于切换视图的UIScreenEdgeGestureRecognizer，还有一个带有自定义UITableView的UITableViewCell。在这个自定义中，UITableViewCell是一个用于滑动单元格的UIPanGestureRecognizer。
我添加了gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:这样两个手势都可以工作，并且gestureRecognizerShouldBegin可以防止垂直滚动的冲突。
问题是，我如何才能赋予UIScreenEdgeGestureRecognizer优先级？当我在屏幕边缘滑动时，我想在不平移单元格的情况下切换视图。我想我应该使用委托方法，但到目前为止，我读得越多，我就越困惑。
自定义代码：

override func viewDidload() {
    var recognizer = UIPanGestureRecognizer(target: self, action: "handlePan:")
    recognizer.delegate = self
    addGestureRecognizer(recognizer)
}

override func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
}

override func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool {
    if let panGesture = gestureRecognizer as? UIPanGestureRecognizer {
        let velocity = panGesture.velocityInView(superview!)
        if fabs(velocity.x) > fabs(velocity.y) { return true }
        return false
    }
    return false
}

视图控制器：

override func viewDidLoad() {
    let rightScreenEdgeRecognizer = EdgePanGesture(target: self, action: "changeView:")
    rightScreenEdgeRecognizer.edges = .Right
    view.addGestureRecognizer(rightScreenEdgeRecognizer)
}

我还试着用以下方法识别识别器：

gestureRecognizer.isKindOfClass(UIScreenEdgePanGestureRecognizer)

和

gestureRecognizer as? UIScreenEdgePanGestureRecognizer

但都失败了。

最佳答案

结果发现我用gestureRecognizer as? UIScreenEdgePanGestureRecognizer看的是正确的方向，但是我应该用gestureRecognizer代替otherGestureRecognizer。

override func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldRequireFailureOfGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    if let recognizer = otherGestureRecognizer as? UIScreenEdgePanGestureRecognizer {
        return true
    }
    return false
}
