iPhone GPS問題模擬器沒有反應

Question

我想創建簡單的GPS應用程序只是爲了在模擬器中顯示簡單的數據。我沒有錯誤就是無法獲取數據。 「didFailWithError」方法是我可以工作的唯一方法:)，這是代碼：

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 

lm = [[CLLocationManager alloc] init]; 
if([CLLocationManager locationServicesEnabled]) 
{ 
    lm.delegate = self; 
    lm.desiredAccuracy = kCLLocationAccuracyBest; 
    //lm.distanceFilter = 1000.0f; 
    [lm startUpdatingLocation]; 
} 

} 


- (void) locationManager: (CLLocationManager *) manager 
didUpdateToLocation: (CLLocation *) newLocation 
fromLocation: (CLLocation *) oldLocation{ 
NSString *lat = [[ NSString alloc] initWithFormat:@"%g", newLocation.coordinate.latitude]; 
txtLatitude.text = lat; 

NSString *lng = [[NSString alloc] initWithFormat:@"%g", newLocation.coordinate.longitude]; 
txtLongitude.text = lng; 

NSString *acc = [[NSString alloc] initWithFormat:@"%g", newLocation.horizontalAccuracy]; 
txtAccuracy.text = acc; 

[acc release]; 
[lat release]; 
[lng release]; 
} 
- (void) locationManager:(CLLocationManager *)manager 
didFailWithError: (NSError *) error 
{ 
NSString *msg = [[NSString alloc] initWithString:@"Error obtaining location"]; 
UIAlertView *alert = [[ UIAlertView alloc] initWithTitle:@"Error" 
       message:msg 
      delegate:nil 
      cancelButtonTitle:@"Done" 
      otherButtonTitles:nil]; 
[alert show]; 
[msg release]; 
[alert release]; 
}

它不會在模擬器中移動。

「的核心位置功能

通過在模擬器CoreLocation框架報告重定位固定在以下座標（精度100米），其對應於1無限循環，加利福尼亞Cupertino 95014 。

緯度：37.3317北 經度：122.0307西」

你可以嘗試添加一個簡單的隨機或定時事件，平s didUpdate ...方法顯式地使用您的首選項的假數據。
