我无法在iphone模拟器中获取当前位置。我将自定义位置设置为纬度和经度到埃及,但没有获得当前位置。
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
//Make this controller the delegate for the map view.
self.MapView.delegate = self;
// Ensure that you can view your own location in the map view.
[self.MapView setShowsUserLocation:YES];
//Instantiate a location object.
locationManager = [[CLLocationManager alloc] init];
[locationManager startUpdatingLocation];
//Make this controller the delegate for the location manager.
[locationManager setDelegate:self];
//Set some parameters for the location object.
[locationManager setDistanceFilter:kCLDistanceFilterNone];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
}
这是委托:
#pragma mark - MKMapViewDelegate methods.
- (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views
{
MKCoordinateRegion region;
region = MKCoordinateRegionMakeWithDistance(locationManager.location.coordinate,2000,2000);
[mv setRegion:region animated:YES];
}
请任何人帮助我。

究竟是什么问题?没有得到一个userLocation你应该有或没有将地图区域移动到正确的位置?
如果是第一个,那么主要是工具问题,而不是代码问题:
如果您的位置位于项目内的gpx文件中,您应该可以通过编辑Scheme / Options / Allow Location Simulation /来选择您的默认位置
您的项目中应该有一个DemoStart.gpx文件,如下所示:
<?xml version="1.0"?>
<gpx version="1.1" creator="Xcode">
<wpt lat="20.88072" lon="10.67429">
<name>Demo Starting Location</name>
</wpt>
</gpx>
(对不起,我太懒了,无法找到埃及的确切坐标)。

您必须首先确保您的CLLocationManager更新其位置。为此,将视图控制器设置为CLLocationManager的委托,您已经这样做,并保存此位置。完成所有设置后尝试拨打startUpdatingLocation
,并将showsUserLocation
设置为YES
。
- (void)locationManager:(CLLocationManager *)manager
didUpdateLocations:(NSArray *)locations {
// If it's a relatively recent event, turn off updates to save power
CLLocation* myLocation = [locations lastObject];
}
请确保您在iOS模拟器版本&gt; = 5.1
上进行测试
