I cannot use wx.canIUse('createMapContext.return.getRegion') in which it always return false. It should return true as I tested with SDKVersion > 1.4.0.
Is this a bug? or I use it wrong?

u should invoke `wx.createMapContext()` to get a MapContext object, then use `if`.
suck as:
var context = wx.createMapContext(mapId);
if (context.getRegion) {
// supported
} else {
// not supported
}

Thank you. It's also good alternative way, I took note of it.
I just found out that it works if I use
wx.canIUse('mapContext.getRegion') |
Problem solved now.
