iphone:CLLocation deletgate方法随机调用

我正在使用

CLLocationManager

获取位置。虽然

我的设备上有GPS设置

，但它会随机显示在

didFailWithError

中定义的状态弹出窗口

我得到的错误是

Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)"

-(void) startGettingCurrentLocation {

    CLLocationManager *locationManager=[[CLLocationManager alloc] init];
    locationManager.delegate=self;
    locationManager.desiredAccuracy=kCLLocationAccuracyNearestTenMeters;

    [locationManager startUpdatingLocation];
}
- (void) locationManager:(CLLocationManager *) manager didFailWithError:(NSError *)error {

    [locatingAlert dismissWithClickedButtonIndex:0 animated:NO];

    UIAlertView *statusAlert;

    statusAlert =  [[UIAlertView alloc] initWithTitle:@"" message:@"In order to use this application properly, you need to allow use of the GPS." delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
    [statusAlert addButtonWithTitle:@"OK"];
    [statusAlert show];

    //Set Default Coordinates it app not able to get location
    if (mainDelegate.currentLatitude == nil) {
        mainDelegate.currentLatitude = @"28.6317021";
    }

    if (mainDelegate.currentLongitude == nil) {
        mainDelegate.currentLongitude = @"-81.423110";
    }
}

看看有什么错误

if([[error code] isEqualTo: kCLErrorLocationUnknown])
{
   The location manager was unable to obtain a location value right now.
}

请看一下您是如何称呼该代表的？我问您是否将cllocationmanager.delegate=self放置在viewdidload中？如果每次更新，为什么要显示警报？相反，您可以删除警报，对吗？编辑问题后，请look@Heena它在模拟器上不起作用。有一些限制，最大的是硬件。你觉得这很奇怪。。
