Question

如何设置地图的默认位置？例如，如果我想在爱尔兰设置它，我该怎么做？它目前默认为北美地区，但我希望它默认为某个坐标。

Answer 1

以下代码将位置设置为SFO。根据您的需要更改坐标以设置所需的位置。

MKCoordinateRegion region = [mapView regionThatFits:MKCoordinateRegionMakeWithDistance(CLLocationCoordinate2DMake(37.78275123, -122.40345442), 200, 200)];
[mapView setRegion:region animated:YES];

如果您要查找用户的当前位置，请使用以下代码。

MKCoordinateRegion region = [mapView regionThatFits:MKCoordinateRegionMakeWithDistance(mapView.userLocation.coordinate, 200, 200)];
[mapView setRegion:region animated:YES];

Answer 2

使用setRegion:animated设置MKMapView的初始区域：

-(void)viewDidLoad {

[super viewDidLoad];

self.mapView.delegate = self;

double delayInSeconds = 0.5;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
    region.center.latitude = 45.442424;
    region.center.longitude = -122.78;
    region.span.latitudeDelta =  0.60;
    region.span.longitudeDelta =  0.60;
    [mapView setRegion:region animated:YES];
});
}
