swift3 - IOS Background Gradients - Storyboard -


is there anyway show background gradients on storyboard instead of firing simulator every-time see looks like

i've created , extension

import uikit  extension cagradientlayer {      func stopwatchcolour() -> cagradientlayer {          let topcolour = uicolor(red: (11/255.0), green: (128/255.0), blue: (105/255.0), alpha: 1)         let bottomcolour = uicolor(red: (39/255.0), green: (90/255.0), blue: (78/255.0), alpha: 1)         let gradientcolours: [cgcolor] = [topcolour.cgcolor, bottomcolour.cgcolor]         let gradientlocations: [float] = [0.0, 1.0]         let gradientlayer: cagradientlayer = cagradientlayer()         gradientlayer.colors = gradientcolours         gradientlayer.locations = gradientlocations [nsnumber]         return gradientlayer     } }

then controller

    let background = cagradientlayer().stopwatchcolour()     background.frame = self.view.bounds     self.view.layer.insertsublayer(background, at: 0)

i recommend trying code in swift playground. swift playground executes code every time type. can see background looks , edit wish. can paste code xcode project without having run simulator.

good luck

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).
