scroll.wrap(layer)

Wraps a layer within a new ScrollComponent. This is useful to create scrollable layers out of imported layers.
译：在一个新的scrollcomponent裹一层。这是从导入层创建滚动层有用。

# Import files from Sketch 
sketch = Framer.Importer.load "imported/Scrollable"

# Wrap the "content" layer group 
scroll = ScrollComponent.wrap(sketch.content)

Now, scroll is the variable name of the ScrollComponent. This also automatically wraps your layer within a ScrollContent layer, which you can select to adjust certain properties like momentum, overdrag or bounce.
译：现在，scroll是ScrollComponent的变量名。这也将自动换一个ScrollContent层，可以选择调整某些动量属性，overdrag或反弹。

# Import files from Sketch 
sketch = Framer.Importer.load "imported/Scrollable"

# Wrap the "content" layer group 
scroll = ScrollComponent.wrap(sketch.content)

# Change scroll properties 
scroll.scrollHorizontal = false
scroll.speedY = 0.5

# Change scroll.content properties 
scroll.content.draggable.momentum = true
scroll.content.draggable.overdrag = false
scroll.content.draggable.bounce = false
