@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
