@implementation MapAppAnnotation

@synthesize coordinate=_coordinate;
- (id)initWithCoordinate:(CLLocationCoordinate2D)coordinate{
self = [super init];
if (self != nil) {
_coordinate = coordinate;
}
return self;
}
- (void)setCoordinate:(CLLocationCoordinate2D)newCoordinate{


}
- (id)initWithCoordinate:(CLLocationCoordinate2D)coordinate andID:(NSUInteger)pinID{
self = [super init];
if (self != nil) {
_coordinate = coordinate;
_pinID = pinID;
}
return self;
}

- (NSString *)title {
return [NSString stringWithFormat:@"Boa %u", _pinID];
}

- (NSString *)subtitle {
return [NSString stringWithFormat:@"%.4f, %.4f", _coordinate.latitude, _coordinate.longitude];
}

@end

MKAnnotationView有draggable属性.....你可以使用它。你可以根据自己的需要进行设置。
