Pergunta
i have some problem when use MKAnnotation
,
I want to add a Annotation on a MapView
so I create a class named AdoptingAnAnnotation
,
the .h
file follow
#import
#import
@interface AdoptingAnAnnotation: NSObject {
}
@synthesize latitude;
@synthesize longitude;
@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
- (NSString *) title;
- (NSString *) subtitle;
@end
and .m file is follow
#import "AdoptingAnAnnotation.h"
@implementation AdoptingAnAnnotation
@synthesize latitude;
@synthesize longitude;
- (id) initWithLatitude:(CLLocationDegrees) lat longitude:(CLLocationDegrees) lng {
latitude = lat;
longitude = lng;
return self;
}
- (CLLocationCoordinate2D) coordinate {
CLLocationCoordinate2D coord = {self.latitude, self.longitude};
return coord;
}
- (NSString *) title {
return @"217 2nd St";
}
- (NSString *) subtitle {
return @"San Francisco CA 94105";
}
@end
Get the error message like illegal interface qualifier
Is my syntax error or other error about the MKAnnotation
?
Solução
Your @synthesize
statements belong in the class implementation, not in the interface. This is why you get the "illegal interface qualifier" error. Finally, your class should adopt the MKAnnotation protocol.
Outras dicas
You posted your .h twice... edit please. Also you have synthesizers in your .h, they belong in .m. And make sure you implement those MKAnnotation methods.
