我需要帮助以在我的 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,但仍然无法正常工作。

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

(void)locationUpdate:(CLLocation *)location每次都会调用该方法,并且location使用 Still 记录时坐标是正确的NSLog().,我的 iPhone 屏幕上没有“蓝点”。区域也未设置。

请看一下,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

这是我的实现文件的一部分:

//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

感谢您的时间!非常感谢!

您在 Interface Builder 中的地图工具包需要检查(查找用户位置)!!
