在iPhone應用程序中的位置問題

下面的代碼給我的位置美國。我如何使用相同的代碼幫助找到英國的位置？在iPhone應用程序中的位置問題

#import "LocalWeatherViewController.h" 
#import "ICB_WeatherConditions.h" 
#import "MapKit/MapKit.h" 

@implementation LocalWeatherViewController 

@synthesize currentTempLabel, highTempLabel, lowTempLabel, conditionsLabel, cityLabel;

@synthesize conditionsImage; 

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    if (1)

     CLLocationCoordinate2D coord; 
     coord.latitude = 45.574779; 
     coord.longitude = -122.685366; 


     MKReverseGeocoder *geocoder = [[MKReverseGeocoder alloc] initWithCoordinate:coord]; 
     geocoder.delegate = self; 
     [geocoder start]; 
    } 
    else 
    { 

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

    ICB_WeatherConditions *weather = [[ICB_WeatherConditions alloc] initWithQuery:query]; 

    [self.currentTempLabel setText:[NSString stringWithFormat:@"%d", weather.currentTemp]]; 
    [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]; 
} 


- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark

這是很難找出你真正想要的東西。請嘗試更清楚地陳述您的問題。 – hop 2011-04-08 00:54:18

找到當前的天氣狀況並找到對城市名稱 – N15H4NJ0 2011-04-08 00:59:14

沒有多大幫助。如果你在你的程序中硬編碼座標，爲什麼你不簡單地編碼城市名稱呢？另外，從來沒有達到其他條款，所以沒有wheather ... – hop 2011-04-08 01:07:35

-1

嘗試緯度= 50.5，經度= 0

如果他想在英國購買MKPlacemark，他可以簡單地創建一個。不需要用反向地理編碼來做愚蠢的舞蹈。 – hop 2011-04-08 00:56:28
