JSONKit

NSError* error;

NSURLRequest* request=[NSURLRequest requestWithRequest:[NSURL URLWithString:@"http://m.weather.com.cn/data/101010100.html"]];NSData* res=[NSURLConnection sendSynchromousRequest:request returningResponse:nil error: nil];NSDictionary *wertherDic=[res objectFromJSONData];NSDictionary *wertherInfo=[wertherDic objectForKey:@"weatherinfo"];txtView.text=[NSString stringWithFormat:@"今天是 %@  %@  %@  的天气状况是：%@  %@ ",[weatherInfo objectForKey:@"date_y"],[weatherInfo objectForKey:@"week"],[weatherInfo objectForKey:@"city"], [weatherInfo objectForKey:@"weather1"], [weatherInfo objectForKey:@"temp1"]];

 NSError *error;      //加载一个NSURL对象      NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://m.weather.com.cn/data/101180601.html"]];      //将请求的url数据放到NSData对象中      NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];      //IOS5自带解析类NSJSONSerialization从response中解析出数据放到字典中      NSDictionary *weatherDic = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];      NSDictionary *weatherInfo = [weatherDic objectForKey:@"weatherinfo"];      txtView.text = [NSString stringWithFormat:@"今天是 %@  %@  %@  的天气状况是：%@  %@ ",[weatherInfo objectForKey:@"date_y"],[weatherInfo objectForKey:@"week"],[weatherInfo objectForKey:@"city"], [weatherInfo objectForKey:@"weather1"], [weatherInfo objectForKey:@"temp1"]];

@property (retain, nonatomic) IBOutlet UITextView *txtView;

@synthesize txtView;
