拖动和滑动(drag/swipe)

和点击一样，拖动和滑动也是常规UI操作，拖动 是从一个UI到另一个UI，滑动 是从一个UI开始，滑动到某个点或朝着某个方向滑动一段距离。其实本质上，拖动是滑动的特殊情况。

Drag

The following example shows how to swipe or drag the “star” to the “shell”.

../../../_images/drag_to.png 
# coding=utf-8

from poco.drivers.unity3d import UnityPoco

poco = UnityPoco()

# drag the "star" to the "shell"
poco('star').drag_to(poco('shell'))

Swipe

The following example shows how to scroll a list by using swipe.

../../../_images/scroll1.gif 
# coding=utf-8

from poco.drivers.unity3d import UnityPoco

poco = UnityPoco()

# swipe the list view up
poco('Scroll View').swipe([0, -0.1])
poco('Scroll View').swipe('up')  # the same as above, also have down/left/right
poco('Scroll View').swipe('down')

# perform swipe without UI selected
x, y = poco('Scroll View').get_position()
end = [x, y - 0.1]
dir = [0, -0.1]
poco.swipe([x, y], end)  # drag from point A to point B
poco.swipe([x, y], direction=dir)  # drag from point A toward given direction and length
