Question

在这里我传递源和目的地的经度和纬度，我得到了响应，但是如何从响应中获得特定的值。我是ios Developer中的新手。我在google API中传递了lat和long

  let travelTimeString : NSString = "https://maps.googleapis.com/maps/api/directions/json?origin=19.120912,72.845121&destination=19.110162,72.853951&sensor=false" as NSString

    print("travelTimeString",travelTimeString)
    let urlStr  = travelTimeString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
    let searchURL: NSURL = NSURL(string: urlStr! as String)!
    do {
        let newdata = try Data(contentsOf: searchURL as URL)
        if let responseDictionary = try JSONSerialization.jsonObject(with: newdata, options: []) as? NSDictionary {
            print("travelTimeString",responseDictionary)


        }} catch {
    }

您可以使用任何外部库，也可以手动解析，例如：

<UserControl.Resources>
    <sys:Double x:Key="BusinessRowHeight">22</sys:Double>
    <local:LineMultiplierConverter x:Key="LineXConverter" BaseValue="{StaticResource BusinessRowHeight}" />
</UserControl.Resources>
<ItemsControl Grid.Row="1" ItemsSource="{Binding CarBusiness}" Margin="0 5 0 0">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <Canvas/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Line StrokeThickness="1" Stroke="LightGray"  
                    X1="0" 
                    Y1="{Binding RelativeSource={RelativeSource Self}, Converter={StaticResource LineXConverter}}" 
                    X2="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl, Mode=FindAncestor}, Path=ActualWidth}" 
                    Y2="{Binding RelativeSource={RelativeSource Self}, Converter={StaticResource LineXConverter}}"/>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
