infoObject(img: UIImage(named: "icon_weather_dry"), title: "Dry"),
infoObject(img: UIImage(named: "icon_weather_wet"), title: "Wet"),
infoObject(img: UIImage(named: "icon_weather_ice_watch"), title: "Ice Watch"),
infoObject(img: UIImage(named:"map_weather_sun"), title: "Sun"),
infoObject(img: UIImage(named: "icon_weather_unknown"), title: "Unkonwon")
]),
LegendObject(name: "Water Level", info: [
infoObject(img: UIImage(named: "flooding"), title: "Flooding Occuring"),
infoObject(img: UIImage(named: "flooding-nodata"), title: "No Dota Available")

]

let  legendView = YVLegendView()
legendView.removeFromSuperview()
legendView.LegendFeed = LegendInfoFeed
legendView.frame = CGRect(x:UIScreen.main.bounds.width - 20.5 , y: 70, width: 219, height:300)
legendView.OpenLegend = { (legendView) in
UIView.animate(withDuration: 1.0, animations: {
legendView.frame = CGRect(x:UIScreen.main.bounds.width - 216 , y: 70, width: 219, height:300)
})
}
legendView.CloseLegend = { (legendView) in
UIView.animate(withDuration: 1.0, animations: {
legendView.frame = CGRect(x:UIScreen.main.bounds.width - 20.5 , y: 70, width: 219, height:300)
})
}
