数量返回为0的情况下，依然会要数据

[csc-EricWu]

func numberOfRowsFor(roolingView: GYRollingNoticeView) -> Int

返回为0的情况下，依然会走
func rollingNoticeView(roolingView: GYRollingNoticeView, cellAtIndex index: Int) -> GYNoticeViewCell

[csc-EricWu]

layoutCurrentCellAndWillShowCell方法改一下
guard let count = self.dataSource?.numberOfRowsFor(roolingView: self) , count > 0 else { return }
