我想开发一张地图，显示我的位置并在地图上显示其他位置的图钉。
我已经显示了地图，也显示了图钉，它也可以找到我，但它不会先放大我的位置。我怎样才能让它首先显示我的位置？当我打开地图视图时，它只显示我输入代码的最后一个引脚。这是我的代码。
地图视图.h
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
@interface mapview : UIViewController {
MKMapView *mapview1;
}
@property (nonatomic, retain) IBOutletMKMapView *mapview1;
-(IBAction)setMap:(id)sender;
-(IBAction)getlocation;
@end
地图视图.m
#import "mapview.h"
#import "NewClass.h"
@implementation mapview
@synthesize mapview1;
-(IBAction)getlocation {
mapview1.showsUserLocation = YES;
}
-(IBAction)setMap:(id)sender {
switch (((UISegmentedControl *) sender).selectedSegmentIndex) {
case 0:
mapview1.mapType = MKMapTypeStandard;
break;
case 1:
mapview1.mapType = MKMapTypeSatellite;
break;
case 2:
mapview1.mapType = MKMapTypeHybrid;
break;
default:
break;
}
}
