在iOS模拟器上使用CLLocationManager查找纬度和经度[重复]

Question

我试图创建一个使用MKMapView打开地图的应用程序，然后通过创建CLLocationManger的委托来查找用户的当前位置。

我已经在下面发布了我的代码。我现在遇到的问题是，尽管打开模拟器时地图确实出现，但它没有从NSLog中给出一个应该经过纬度和经度的位置或新的航向。

我是Objective-C和应用程序开发的新手，有人看到我是否遗漏了ClLocationManager的一些协议吗？谢谢你的帮助。

对不起，代码有点草率，很快就贴进去了。

  #import "ViewController.h"
  #import <MapKit/MapKit.h>
  #import <CoreLocation/CoreLocation.h>

  @interface ViewController () <CLLocationManagerDelegate>
  @property (nonatomic,strong)CLLocationManager * myLocationManger;
  @property (nonatomic,strong) IBOutlet MKMapView *myMapView;
  @end

  @implementation ViewController

  - (void)viewDidLoad {
      [super viewDidLoad];
      NSLog(@"insdie view did load");

     //    Setting the map to be big as the view
      self.myMapView =[[MKMapView alloc]init];

//Initial Property to Map
     self.myMapView =[[MKMapView alloc] init];

//Set type to Standard
self.myMapView.mapType = MKMapTypeStandard;

//Set Mask for AutoReszing
self.myMapView.autoresizingMask = UIViewAutoresizingFlexibleWidth |                                              UIViewAutoresizingFlexibleHeight;

//Add the View!
[self.view addSubview:self.myMapView];

///*Now lets Use my CLLocation Manager to Locate the iPhone's Posistion*////



//Chekcs if Location Services are Enabled
if ([CLLocationManager locationServicesEnabled]) {
    self.myLocationManger = [[CLLocationManager alloc] init];
    self.myLocationManger.delegate = self;

    [self.myLocationManger startUpdatingLocation];



}
else{
    //Location Services are available we will need software to ask to turn this On
    //The user is SOL if they refuse to turn on Location Services
    NSLog(@"Location Services not enabled");


}



}

  -(void)locationManager:(CLLocationManager *)manager
      didUpdateToLocation:(CLLocation *)newLocation
      fromLocation:(CLLocation *)oldLocation
  {
      //This method will show us that we recieved the new location
      NSLog(@"Latitude = %f",newLocation.coordinate.latitude );
      NSLog(@"Longitude =%f",newLocation.coordinate.longitude);

  }

  -(void)locationManager:(CLLocationManager *)manager
   didFinishDeferredUpdatesWithError:(NSError *)error{
      NSLog(@"Error with Updating");
  }



  -(void)locationManager:(CLLocationManager *)manager
  didFailWithError:(NSError *)error
  {
//Failed to recieve user's location
NSLog(@"failed to recived user's locatio");
  }

我发现在新的iOS8中，您需要将两个键添加到Plist。这篇文章很好地解释了这个过程。
