CLLocation在iOS7中未更新

Question

我在viewDidLoad中实现以下代码

locationManager = [[CLLocationManager alloc] init];
locationManager.distanceFilter = kCLDistanceFilterNone; 
locationManager.desiredAccuracy = kCLLocationAccuracyBest; 
[locationManager startUpdatingLocation];

我试图通过每秒获取我的位置

 CLLocation *location = [locationManager location];
 CLLocationCoordinate2D coordinate = [location coordinate];
 NSLog(@"[%f,%f]",coordinate.latitude,coordinate.longitude);

我尝试在iOS模拟器中设置自定义位置，但是该位置从未更新过，我也曾在我的iPhone设备上尝试过它，看来它只能捕获第一个位置，而后续位置未更新。

请给我建议如何解决

尝试此方法以获得连续更新的纬度和经度

(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{  
    CLLocation *location_updated = [locations lastObject];   
    NSLog(@"updated coordinate are %@",location_updated);
}
