The point at which the origin of the content view is offset from the origin of the scroll view

content view origin相对于scroll view origin的偏移

可以把content view理解为设备屏幕，scroll view origin是要显示的内容

显示内容下拉时content view origin 在 scroll view origin 上面, 此时contentOffset.y < 0， 这就是为什么下拉scroll view时contentOffset.y < 0
