MKMapKit不显示userLocation

我需要帮助在MapView上显示用户的位置。我已经完成了我可能在网上找到的所有内容,但它仍然无效。

我的AppDelegate中有一个CLLocationManager,它在我的viewController中调用locationUpdate。

每次调用(void)locationUpdate:(CLLocation *)location方法,location坐标在使用NSLog().时记录正确仍然在我的iPhone屏幕上没有“蓝点”。该地区也没有设定。

如果我遗失任何东西,请看看并告诉我。

这是我的标题文件:

//My .h file
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
#import <MapKit/MKAnnotation.h>
#import <MapKit/MKReverseGeocoder.h>
@interface FirstViewController : UIViewController <MKMapViewDelegate>
{
    MKMapView *mapView;
}
-(void)locationUpdate:(CLLocation *)location;
-(void)locationError:(NSError *)error;
@end

这是我的实施文件的一部分:

//My .m file
#import "FirstViewController.h"
@implementation FirstViewController
- (void)viewDidLoad
{
    mapView = [[MKMapView alloc] initWithFrame:self.view.bounds];
    mapView.showsUserLocation = YES;
    mapView.mapType = MKMapTypeStandard;
    mapView.delegate = self;

    CLLocationCoordinate2D location;
    MKCoordinateRegion region;// = {{0.0,0.0},{0.0,0.0}};
    location.latitude = -33.8771;
    location.longitude = 18.6155;
    MKCoordinateSpan span;
    span.latitudeDelta = 0.01;
    span.longitudeDelta = 0.01;
    region.span = span;
    region.center = location;
    [mapView setRegion:region animated:TRUE];
    [mapView regionThatFits:region];
    [super viewDidLoad];
}
-(void)locationUpdate:(CLLocation *)location
{
    CLLocationCoordinate2D loc = [location coordinate];
    [mapView setCenterCoordinate:loc];
    if([mapView showsUserLocation] == NO)
    [mapView setShowsUserLocation:YES];
    NSLog(@"User Loc: %f, %f", mapView.userLocation.location.coordinate.latitude,
                     mapView.userLocation.location.coordinate.longitude);
    NSLog(@"In MapView: %@",[location description]);
}
@end

感谢您的时间! 非常感谢!

Interface Builder中的Map工具包需要选中(查找用户位置)!!
