ios - How do I prevent table view scrolling behind a view? -


in tableviewcontroller, have translucent overlay view message. overlay displayed on tableviewcontroller correctly can still scroll table view behind overlay view. how can prevent scrolling when overlay on top?

i constructed custom overlay view in tableviewcontroller:

override func viewdidload() {     super.viewdidload()      loaddata(         id,         success: {(doc) -> () in             let frame = cgrect(x: 0, y: 0, width: self.view.bounds.size.width, height: self.view.bounds.size.height)              let overlayview = emptycollectionview(frame : frame)             overlayview.backgroundcolor = uicolor(red: 0, green: 0, blue: 0, alpha: 0.8)             self.view.addsubview(overlayview)              self.tableview.reloaddata()         },         error: {..}) }

i tried self.tableview.isuserinteractionenabled = false

ok - if in uitableviewcontroller, self.view refers uitableview itself. want add overlayview subview of table view's superview...

try this:

tableview.superview?.addsubview(overlayview)

you can simplify few things well, , should implement sizing control handle changes such device rotation:

let overlayview = emptycollectionview(frame: tableview.frame)  overlayview.autoresizingmask = [.flexiblewidth, .flexibleheight]  overlayview.backgroundcolor = uicolor(red: 0, green: 0, blue: 0, alpha: 0.8)  tableview.superview?.addsubview(overlayview)

Retrieving ETA (estimated time of arrival) with Google Distance Matrix API and public transit as transport mode -

Image
is possible retrieve eta google's distancematrix api (or alternative api). fyi, eta different duration, when using public transport. following example clarify request. when leave on friday @ 8.15 i'll able catch train @ 8.30 , arrive @ 9.00 am. google says duration 30 minutes. however, when leave on saturday @ 8.15 i'll able catch first train @ 9.00 , arrive @ 9.30 am. google still says duration 30 minutes, means ignore delay. google map supports functionality there api around giving me eta instead of duration. can see, distance-matrix' response no good. clarifying question little. eta estimated time of arrival , it's clear user wants know entire duration of transport (including waiting time public transport).
