CAShapeLayer（图层）使用Swift中的Gesture将一个地方移动到另一个地方

Question

下面我的代码我希望使用手势移动shapeLayer（图层）。

def paymentEntriesIds = paymentEntryIds(selectedCategory)

def c = Payment.createCriteria()

def result = new ArrayList()

// If there are no payment entries matching category criteria, we return empty list anyway, so there
// is no need querying payments.
if (paymentEntriesIds.size() > 0) {
    result = c {
        paymentEntries {
            inList("id", paymentEntriesIds)
        }

        if (importEntryId != null) {
            eq("importEntry.id", importEntryId)
        }
        if (query != null) {
            ilike("description", query)
        }
        // Omitted ordering and paging
    }
}

result

我使用波纹管触摸功能识别图层，但没有用。

let shapeLayer = CAShapeLayer()
let ellipsePath = UIBezierPath(ovalInRect: CGRectMake(100, 200, width , height))
shapeLayer.path = ellipsePath.CGPath
shapeLayer.fillColor = UIColor.clearColor().CGColor
shapeLayer.strokeColor = UIColor.blueColor().CGColor
shapeLayer.lineWidth = 1
shapeLayer.sublayers?.removeAll()
self.view.layer.addSublayer(shapeLayer)
