- (id) initWithCoordinates:(CLLocationCoordinate2D)paramCoordinates
title:(NSString *)paramTitle
subTitle:(NSString *)paramSubTitle;

MyAnnotation.m 文件

if (self != nil){
_coordinate = paramCoordinates;
_title = paramTitle;
_subtitle = paramSubTitle;
}
return(self);

/* Create a map as big as our view */

self.myMapView.delegate = self;
/* Set the map type to Standard */
self.myMapView.mapType = MKMapTypeStandard;
self.myMapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
/* Add it to our view */

/* This is just a sample location */

/* Create the annotation using the location */
MyAnnotation *annotation =

subTitle:@"My Sub Title"];
/* And eventually add it to the map */
