在iPhone应用程序中的位置问题

下面的代码给我的位置美国。我如何使用相同的代码帮助找到英国的位置？在iPhone应用程序中的位置问题

#import "LocalWeatherViewController.h"

#import "MapKit/MapKit.h" 

@implementation LocalWeatherViewController

     coord.longitude = -122.685366; 


     MKReverseGeocoder *geocoder = [[MKReverseGeocoder alloc] initWithCoordinate:coord]; 
     geocoder.delegate = self;

    else 
    { 

     [self performSelectorInBackground:@selector(showWeatherFor:) withObject:@"97217"];

    [self.highTempLabel setText:[NSString stringWithFormat:@"%d", weather.highTemp]]; 
    [self.lowTempLabel setText:[NSString stringWithFormat:@"%d", weather.lowTemp]]; 
    [self.conditionsLabel setText:weather.condition]; 
    [self.cityLabel setText:weather.location]; 

    self.conditionsImageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:weather.conditionImageURL]]; 

    [weather release]; 

    [pool release]; 
}

这是很难找出你真正想要的东西。请尝试更清楚地陈述您的问题。 – hop 2011-04-08 00:54:18

找到当前的天气状况并找到对城市名称 – N15H4NJ0 2011-04-08 00:59:14

没有多大帮助。如果你在你的程序中硬编码坐标，为什么你不简单地编码城市名称呢？另外，从来没有达到其他条款，所以没有wheather ... – hop 2011-04-08 01:07:35

-1

尝试纬度= 50.5，经度= 0

如果他想在英国购买MKPlacemark，他可以简单地创建一个。不需要用反向地理编码来做愚蠢的舞蹈。 – hop 2011-04-08 00:56:28
