MKAnnotation构造函数错误
|
我在使用MKAnnotation时遇到问题，我为注释创建了一个类“ cgdMapAnnotation \”，其中一个构造函数如下所示：
+ (id) initWithCoordinate:(CLLocationCoordinate2D)coordinate andTitle:(NSString*) title andSubtitle:(NSString*) subtitle {
self = [super alloc];
_coordinate = coordinate;
_title = [title retain];
_subtitle = [subtitle retain];
return self;
}
cgdMapAnnotation *placemark=[[[cgdMapAnnotation alloc] initWithCoordinate:centerCoordinate andTitle:@\"Title\" andSubtitle:@\"SubTitle\" ] autorelease];
-[cgdMapAnnotation initWithCoordinate:andTitle:andSubtitle:]: unrecognized selector sent to instance 0x33cf2fe0

- (id)initWithCoordinate:(CLLocationCoodinate2D)coordinate andTitle:(NSString*) title andSubtitle:(NSString*) subtitle { if( self = [super init] ) { _coordinate = coordinate; _title = [title retain]; _subtitle = [subtitle retain]; } return self; }
