如何在MKMapView上添加按鈕？

Question

我想在地圖上有按鈕的iPhone應用程序，我該怎麼做？我已經實施MKMapView並將其設置爲longitude/latitude並將其集中在我想要的位置。

Answer 1

你就不細說了你的問題，所以我想你想，

Use MKUserTrackingBarButtonItem

- (void)viewDidLoad 
    { 
     [super viewDidLoad];  
     MKUserTrackingBarButtonItem *buttonItem = [[MKUserTrackingBarButtonItem alloc] initWithMapView:self.map]; 
     self.navigationItem.rightBarButtonItem = buttonItem; 
    } 

AMKUserTrackingBarButtonItem對象是一家專門欄按鈕項目，允許用戶通過用戶跟蹤模式切換。例如，當用戶點擊該按鈕時，地圖視圖在跟蹤具有和不具有標題的用戶之間切換。該按鈕還反映當前的用戶跟蹤模式，如果設置在別處。此欄按鈕項目與一個地圖視圖關聯。

試試吧....

- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation 
{ 
    MKPinAnnotationView *pinAnnotation = nil; 
    if(annotation != myMapView.userLocation) 
    { 
     static NSString *defaultPinID = @"myPin"; 
     pinAnnotation.pinColor = MKPinAnnotationColorRed; 
     pinAnnotation = (MKPinAnnotationView *)[myMapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID]; 
     if (pinAnnotation == nil) 
      pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease]; 

     pinAnnotation.canShowCallout = YES; 

     infoButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 25, 25)]; 
     [infoButton setBackgroundImage:[UIImage imageNamed:@"arrow_go_map.png"] forState:UIControlStateNormal]; 
     pinAnnotation.rightCalloutAccessoryView = infoButton; 
     [infoButton addTarget:self action:@selector(detailBtnClk:) forControlEvents:UIControlEventTouchUpInside]; 
    }  
    return pinAnnotation; 
} 

希望我幫助
