Note

The code for the forecast can be found at http://openweathermap.org/weather-conditions.

Then, we change the viewWillAppear function in PrettyWeatherViewController again. We do this to raise three calls to get the current weather and forecast:

override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) locationDatastore = LocationDatastore() { [weak self] location in FlickrDatastore().retrieveImageAtLat(location.lat, lon: location.lon){ image in self?.render(image) return } let weatherDatastore = WeatherDatastore() weatherDatastore.retrieveCurrentWeatherAtLat(location.lat, lon: location.lon) { currentWeatherConditions in self?.renderCurrent(currentWeatherConditions) return } weatherDatastore.retrieveHourlyForecastAtLat(location.lat, lon: location.lon) { hourlyWeatherConditions in self?.renderHourly(hourlyWeatherConditions) return } weatherDatastore.retrieveDailyForecastAtLat(location.lat, lon: location.lon, dayCnt: 7) { hourlyWeatherConditions in self?.renderDaily(hourlyWeatherConditions) return } } }
