沒有得到正確的地圖使用MKMapVIew

Question

我創建了一個mapview使用MKMapView。一切工作正常，但是我得到的地圖和我應該得​​到的地圖有所不同。在我看來，地圖即將到來，但我猜不正確。請查看差異並讓我知道是什麼問題。 感謝 這裏是我的ViewController.m

#import "ViewController.h" 
@interface ViewController() 
@end 
@implementation ViewController 


- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
mapView=[[MKMapView alloc]initWithFrame:CGRectMake(0, 0, 320, 400)]; 
mapView.delegate=self; 
[mapView setMapType:MKMapTypeStandard]; 
[mapView setZoomEnabled:YES]; 
[mapView setScrollEnabled:YES]; 

MKCoordinateRegion region = { {0.0, 0.0},{0.0,0.0}}; 
region.center.latitude = 12.9667; 
region.center.longitude = 77.5833; 
region.span.longitudeDelta = 0.01f; 
region.span.latitudeDelta = 0.01f; 
[mapView setRegion:region animated:YES]; 
[self.view addSubview:mapView]; 

DisplayMap *annotation = [[DisplayMap alloc]init]; 
annotation.title = @" Bangalore"; 
annotation.subtitle = @"Silver Jublee Park"; 
annotation.coordinate = region.center; 
[mapView addAnnotation:annotation]; 
} 


-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation: 

(id <MKAnnotation>)annotation 
    { 
MKPinAnnotationView *pinView = nil; 
if(annotation != mapView.userLocation) 

{ 
     static NSString *defaultPinID = @"com.invasivecode.pin"; 
     pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID]; 
     if (pinView == nil) pinView = [[[MKPinAnnotationView alloc] 
             initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease]; 
    pinView.pinColor = MKPinAnnotationColorRed; 
    pinView.canShowCallout = YES; 
    pinView.animatesDrop = YES; 
} 
    return pinView; 
} 


- (void)didReceiveMemoryWarning 
{ 
[super didReceiveMemoryWarning]; 
} 
@end 

@implementation DisplayMap 
@synthesize coordinate,title,subtitle; 
-(void)dealloc{ 
[title release]; 
[subtitle release]; 
[super dealloc]; 
} 
@end 

ViewController.h

#import <UIKit/UIKit.h> 
#import <MapKit/MapKit.h> 
@interface ViewController : UIViewController<MKMapViewDelegate> { 
MKMapView *mapView; 
} 
@end 


@class DisplayMap; 
@interface DisplayMap : NSObject <MKAnnotation> { 
CLLocationCoordinate2D coordinate; 
NSString *title; 
NSString *subtitle; 
} 
@property (nonatomic, assign) CLLocationCoordinate2D coordinate; 
@property (nonatomic, copy) NSString *title; 
@property (nonatomic, copy) NSString *subtitle; 
@end 

我正在以下地圖

我應該得到的followi NG地圖

當我把你使用到谷歌地圖，我去，你所看到的同一個地方的座標，有不對的地方，你想你「應該」獲得。你是否驗證過座標？你認爲你應該去的蕾絲的座標是什麼？

這裏有兩個地方http://goo.gl/maps/TrM3q

之間的路由根據Goolge的您所期待的iOS到應該的地方〜2000公里從你使用的是coordiantes，這是不會發生的路程。
