iphone – 转到缩放到当前位置功能(MapKit)

概述我有一个mapView,它使用viewDidLoad缩放到当前位置： #define METERS_PER_MILE 1609.344// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.- (void)viewDidLoad{ [super view 我有一个mapVIEw,它使用vIEwDIDLoad缩放到当前位置：

#define METERS_PER_MILE 1609.344// Implement vIEwDIDLoad to do additional setup after loading the vIEw,typically from a nib.- (voID)vIEwDIDLoad{    [super vIEwDIDLoad];    mapVIEw.showsUserLocation=TRUE;    // zoom to  a specific area    CLLocationCoordinate2D zoomLocation;    zoomLocation.latitude = -28.994167;    zoomLocation.longitude = 134.866944;    MKCoordinateRegion vIEwRegion = MKCoordinateRegionMakeWithdistance(zoomLocation,1900*METERS_PER_MILE,1900*METERS_PER_MILE);    MKCoordinateRegion adjustedRegion = [mapVIEw regionThatFits:vIEwRegion];        // make sure the Google water mark is always visible    mapVIEw.autoresizingMask =    (UIVIEwautoresizingFlexibleWIDth | UIVIEwautoresizingFlexibleHeight);    [mapVIEw setRegion:adjustedRegion animated:YES];            mapVIEw.delegate=self;    searchbar.delegate = self;}

这很好用.我添加了一个搜索栏和一个跳转到特定地址位置的函数.这也很好.我现在想要添加一个按钮来跳回当前位置.你可以帮我一把吗？

干杯

解决方法 您需要将地图的中心设置为点按该按钮的当前位置.说,像这样：

- (IBAction)showCurrentLocation {            [mapVIEw setCenterCoordinate:mapVIEw.userLocation.location.coordinate animated:YES];}
