Iphone MKMap针颜色

我是Xcode新手，基本上我有一个

MKMapView

，我想为我的每个管脚添加单独的颜色。我目前已经用注释标记了管脚

LocationAnnotation.h：

@interface LocationAnnotation : NSObject <MKAnnotation>

@property (nonatomic, assign) CLLocationCoordinate2D coordinate;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSString *subtitle;

@end

我的每个坐标在 MainMapViewController.h：

#define TheKingBill_LATITUDE 50.431379
#define TheKingBill_LONGITUDE -3.685495

 //Annotation

NSMutableArray * locations = [[NSMutableArray alloc] init];
CLLocationCoordinate2D location;
LocationAnnotation * myAnn;

//The King Bill Annotation
myAnn = [[LocationAnnotation alloc] init];
location.latitude = TheKingBill_LATITUDE;
location.longitude = TheKingBill_LONGITUDE;
myAnn.coordinate = location;
myAnn.title = @"The King Bill";
myAnn.subtitle = @"Another Pub In Town";
[locations addObject:myAnn];

 //The Seven Stars Annotations
myAnn = [[LocationAnnotation alloc] init];
location.latitude = TheSevenStars_LATITUDE;
location.longitude = TheSevenStars_LONGITUDE;
myAnn.coordinate = location;
myAnn.title = @"The Royal Seven Stars Hotel";
myAnn.subtitle = @"Hotel In Town";
[locations addObject:myAnn];

 [self.MainMapView addAnnotations:locations];

有什么想法我需要添加，使每个针的颜色不同

谢谢

好了，现在我的另一个地图链接到这个LocationAnnotation文件时出现了问题。我还想添加彩色别针到这个。如果新代码与我以前的mapviewcontroller相同，这将是理想的。这是代码
