MKMapKit没有显示userLocation

Question

我需要帮助显示用户的位置在我的MapView。我已经做了我可以在网上找到的一切，但它仍然不起作用。

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

每次调用(void)locationUpdate:(CLLocation *)location方法时，location坐标都是正确的，当仍然使用NSLog().登录时，在我的iPhone屏幕上没有“蓝点”。这个地区也没有被设定好。

请看一看，如果我遗漏了什么，请告诉我。

这是我的头文件：

//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

--这是我实现文件的一部分：

//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

谢谢您抽时间见我!非常感谢！

界面生成器中的地图工具包需要检查(查找用户位置)！！
