Question

我在我的collectionView单元格中显示三个视图。一个完整的中间和预览下一个和上一个在contentView的角落。并使用panGesture向上滑动中间视图。如何在侧视图中禁用panGesture？

我在内容视图中添加了panGestureRecognizer。但是我不想让侧面视图识别这个手势，而且我想让侧面图像变得模糊不清。我怎么能这样做？

您可以使用UIGestureRecognizerDelegate。实施方法：

func wasDragged(gestureRecognizer: UIPanGestureRecognizer) {

    if gestureRecognizer.state == UIGestureRecognizerState.began {
        print("was dragged began")
    }
    if gestureRecognizer.state == UIGestureRecognizerState.changed {
        print("was dragged change \(gestureRecognizer.location(in: self.view))")
        testTouches(touches: gestureRecognizer.location(in: self.view))
    }
    if gestureRecognizer.state == UIGestureRecognizerState.ended {
        print("was dragged ended")
    }
}

比实现测试触摸点的方法：

func testTouches(touches: CGPoint) {
    // Get location of touch

    let touchLocation = touches
    // Convert the location of the side views to this view controller's view coordinate system
    let sideViewFrame = self.view.convert(sideView.frame, from: sideView.superview)// Check if touch is inside side view
    if sideViewFrame.contains(touchLocation) {
            // do nothing
        }
        else {
            // do something
        }
}

在contentView中的sideViews上禁用手势
