位置管理器didUpdateLocations沒有被調用。

self.locationManager = [[CLLocationManager alloc] init]; 

self.locationManager.delegate = self; 

[self.locationManager startUpdatingLocation]; 

for call back i am using this delegate method 

- (void)locationManager:(CLLocationManager)manager didUpdateLocations:(NSArray)locations 
{ 
    NSLog(@"%@", [locations lastObject]); 
} 

Answer 1

進口框架CoreLocation

self.locationManager = [[CLLocationManager alloc] init]; 
    self.locationManager.delegate = self; 
    if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) 
    { 
     [self.locationManager requestWhenInUseAuthorization]; 
    } 
    [self.locationManager startUpdatingLocation]; 

在iOS8上和較新的，你有權要求致電requestAlwaysAuthorization或requestWhenInUseAuthorization使用明確的定位服務的權限。
