ios - ios如何从URL中获取数据

Question

嘿，我是 ios 新手，请帮助从这个 URL 获取数据...

NSString *urlString = @" http://api.openweathermap.org/data/2.5/forecast/daily?q=Indore&mode=json&units=metric&cnt=10&APPID=fc632e2569dbdbb07ca79e239faa0281";

Answer 1

像这样使用 NSUrlSession:

NSString *urlString = @"http://api.openweathermap.org/data/2.5/forecast/daily?q=Indore&mode=json&units=metric&cnt=10&APPID=fc632e2569dbdbb07ca79e239faa0281";
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:urlString] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
    // handle the response
}] resume];
