First pick the best weather API for your purpose: https://stackoverflow.com/questions/507441/best-weather-apis
首先选择最适合您的天气 API：https: //stackoverflow.com/questions/507441/best-weather-apis
Most APIs, including Google, return their result in XML format.
Quickly written example code to get you started with the Google Weather API:
大多数 API（包括 Google）以 XML 格式返回其结果。
快速编写示例代码，让您开始使用 Google Weather API：
NSString * location = @"Amsterdam";
NSString * address = @"http://www.google.co.uk/ig/api?weather=";
NSString * request = [NSString stringWithFormat:@"%@%@",address,location];
NSURL * URL = [NSURL URLWithString:request];
NSError * error;
NSString* XML = [NSString stringWithContentsOfURL:URL encoding:NSASCIIStringEncoding error:&error];
// Extract current temperature the 'dirty' way
NSString * temp = [[[[XML componentsSeparatedByString:@"temp_c data=\""] objectAtIndex:1] componentsSeparatedByString:@"\""] objectAtIndex:0];
NSLog(@"It's currently %@ degree in %@.", temp, location);
// Parse the XML with NSXMLDocument to extract the data properly
NSXMLDocument * doc = [[NSXMLDocument alloc] initWithXMLString:XML options:0 error:NULL];
Output:
输出：
It's currently 14 degree in Amsterdam.
目前在阿姆斯特丹是 14 度。
