Scrollview can't oblique move by touch

Is there any parameter can be set to let scrollview move x and y at the same time by touch?

Just like this video:

example:iOS’s directionalLockEnabled

I resolve:

lock the scrollview, and set position by math from event.x,event.y,event.xStart,event.yStart

Then unlock the scrollview.
