iPhone SDK MapKIt 多点和注释
我是 iPhone SDK 开发的新手,我正在尝试使用 MapKit 制作一个应用程序,我已经完成了第一步,我想向应用程序添加多个引脚和注释,但我在这里迷失了。
以下是代码,我如何向此代码添加更多引脚
-(void)viewDidLoad{
[super viewDidLoad];
[mapView setMapType:MKMapTypeStandard];
[mapView setZoomEnabled:YES];
[mapView setScrollEnabled:YES];
MKCoordinateRegion region={{0.0,0.0,},{0.0,0.0}};
region.center.latitude = 26.438047;
region.center.longitude = 50.116422;
region.span.latitudeDelta=0.01f;
region.span.longitudeDelta=0.01f;
[mapView setRegion:region animated:YES];
[mapView setDelegate:self];
DisplayMap *ann = [[DisplayMap alloc] init];
ann.title = @"Corporate Office";
ann.subtitle =@"King Khalid Street";
ann.coordinate=region.center;
[mapView addAnnotation:ann];
}
-(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;
pinView.calloutOffset= CGPointMake(-5, 5);
}
else {
[mapView.userLocation setTitle:"I am here"];
}
return pinView;
}
I am new to IPhone SDK Development i am trying to make an application with MapKit i have done the first bit i want to add multiple pins and annotation to the application but i am lost here.
Following is the code how can i add more pins to this code
-(void)viewDidLoad{
[super viewDidLoad];
[mapView setMapType:MKMapTypeStandard];
[mapView setZoomEnabled:YES];
[mapView setScrollEnabled:YES];
MKCoordinateRegion region={{0.0,0.0,},{0.0,0.0}};
region.center.latitude = 26.438047;
region.center.longitude = 50.116422;
region.span.latitudeDelta=0.01f;
region.span.longitudeDelta=0.01f;
[mapView setRegion:region animated:YES];
[mapView setDelegate:self];
DisplayMap *ann = [[DisplayMap alloc] init];
ann.title = @"Corporate Office";
ann.subtitle =@"King Khalid Street";
ann.coordinate=region.center;
[mapView addAnnotation:ann];
}
-(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;
pinView.calloutOffset= CGPointMake(-5, 5);
}
else {
[mapView.userLocation setTitle:"I am here"];
}
return pinView;
}

您已经走在正确的轨道上,只需重用您的代码即可获得多个点。
例如:
在结果中,将显示不同坐标的 5 个点。 (具有相同的名称和副标题)。
编辑:显示不同的引脚图像。您必须将新字段作为 NSString *image 添加到 DisplayMap。并在 for 循环中添加路径图像。
}
you are on the right track already, just reuse your code to make multiple points.
for example :
in result, will display 5 points in different coordinate. (with same name and subtitle).
Edited: show different pin image. you have to add new field as NSString *image to DisplayMap. and add your path image inside for loop.
