Deprecated, consider using Jupiter instead.

CZWeatherKit is a simple, extensible weather library for iOS, tvOS, and OS X that allows for easy fetching of weather data from various weather services.

What's New in v2.2.7

Features

• tvOS Support*.
• Caching Support.
• Support for historical and hourly data.
• Request batching when using a weather service.
• Improved request management when sending frequent requests.
• Addition of more data, including humidity, wind speed, and more.

*Note: Features requiring MapKit are unsupported with tvOS.

Getting Started

CocoaPods

Add the following to your Podfile:

    pod "CZWeatherKit"

Usage

Included in this project is a Swift playground, CZWeatherKit.playground, that will let you play around with CZOpenWeatherMapRequest. However if you're as lazy as I am, here are some code snippets to get you started:

Wunderground

Getting Current Conditions, Obj-C

#import <CZWeatherKit/CZWeatherKit.h>

CZWundergroundRequest *request = [CZWundergroundRequest newConditionsRequest];
request.location = [CZWeatherLocation locationFromCity:@"Seattle" state:@"WA"];
request.key = @"wundergroundApiKey";
[request sendWithCompletion:^(CZWeatherData *data, NSError *error) {
	CZWeatherCurrentCondition *condition = data.current;
	// dreams come true here
}];

Getting Forecast Conditions, Swift

import CZWeatherKit

let request = CZWundergroundRequest.newForecastRequest()
request.location = CZWeatherLocation(fromCity: "Seattle", state: "WA")
request.key = "wundergroundApiKey"
request.sendWithCompletion { (data, error) -> Void in
    if let weather = data {
  		for forecast in weather.dailyForecasts {
  			// dreams come true here
  		}
    }
}

OpenWeatherMap

Getting Current Conditions, Obj-C

#import <CZWeatherKit/CZWeatherKit.h>

CZOpenWeatherMap *request = [CZOpenWeatherMapRequest newCurrentRequest];
request.location = [CZWeatherLocation locationFromCity:@"Seattle" state:@"WA"];
[request sendWithCompletion:^(CZWeatherData *data, NSError *error) {
	CZWeatherCurrentCondition *condition = data.current;
	// dreams come true here
}];

Getting Forecast Conditions, Swift

import CZWeatherKit

let request = CZOpenWeatherMapRequest.newDailyForecastRequestForDays(3)
request.location = CZWeatherLocation(fromCity: "Seattle", state: "WA")
request.sendWithCompletion { (data, error) -> Void in
    if let weather = data {
  		for forecast in weather.dailyForecasts {
  			// dreams come true here
  		}
    }
}

Using a Weather Service

A weather service allows for the dispatching of weather data requests and allows for more fine-grained control over how requests are handled as opposed to the interface provided by CZWeatherDataRequest. An ideal use case for a weather service is powering a weather app.

import CZWeatherKit

let service = CZWeatherService()
request = CZOpenWeatherMapRequest.newCurrentRequest()
request.location = CZWeatherLocation(fromCity: "Seattle", state: "WA")
service.dispatchRequest(request, completion: { (data, error) -> Void in
    if let weather = data {
        // dreams come true here
    }
})

Supported Weather APIs

CZWeatherKit currently supports the following weather services:

• Weather Underground
• Open Weather Map
• Forecast.io
• World Weather Online : World Weather Online support hasn't made its way into 2.0 yet; there is an outstanding issue for adding support. To give me a sense of how important this is to users, please leave a +1 in the comments of the issue if you need this feature.

Climacons

CZWeatherKit supports Climacons out of the box. The Climacons Font is a font set created by Adam Whitcroft featuring weather icons.

Architecture
