openweathermap-免费的天气预报接口

openweathermap-免费的天气预报接口



其官方网址为：http://www.openweathermap.org/api



静态截图：



具备以下的一些特点：

1. Current weather data 当前天气的数据

2. 5 and 16 day forecast 5到16天的天气预报

3. Historical data 以往的天气信息

4. Weather stations 气象站点

5. Weather map layers 详细的气象信息

以下是本人的测试结果（根据经纬度直接获取天气预报的信息的接口示例，返回的数据为JSON）：

// http://www.openweathermap.org/api // http://www.openweathermap.org/current // http://www.openweathermap.org/forecast // http://www.openweathermap.org/weather-conditions NETWorkRequest *request = [[NETWorkRequest alloc] initWithUrlString:@"http://api.openweathermap.org/data/2.5/forecast/daily?lat=39.88293652833437&lon=116.4621119300779&lang=zh_cn"];

NETWorkConnection *connection = [[NETWorkConnection alloc] initWithRequest:request];
[connection infoBlock:^(NSDictionary *info, NETWorkConnection *myConnection) {
} progressBlock:^(long long currentBytes, long long totalBytes, NETWorkConnection *myConnection) {
} resultBlock:^(NSDictionary *info, NSData *data, NSError *error, NETWorkConnection *myConnection) {
NSLog(@"%@", [data toPropertyList]);
}];
[connection start];

其他的就自己去看官方api了，不过是英文的。
