In your View Controller in which you're implementing MapView, you must be implementing MapView's delegate method, viewForAnnotation!!!
Implement it like this:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
MKAnnotationView * annotationView = nil;
[mapLoadingIndicatorView stopAnimating];
if ([annotation isKindOfClass:[MKUserLocation class]]) {
[self.mapView.userLocation setTitle:#"User1"];
return annotationView;
}
annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"currentAnnotation"];
annotationView.canShowCallout = YES;
return annotationView;
}
And also make sure you've made an AddressAnnotation Class in which
AddressAnnotation.h
#interface AddressAnnotation : NSObject <MKAnnotation> {
CLLocationCoordinate2D coordinate;
NSString * title_;
NSString * subtitle_;
}
#property (nonatomic, readwrite, assign) CLLocationCoordinate2D coordinate;
#property (nonatomic, retain) NSString * title_;
#property (nonatomic, retain) NSString * subtitle_;
#end
And AddressAnnotation.m:
#implementation AddressAnnotation
#synthesize coordinate, title_, subtitle_;
- (id)initWithCoordinate:(CLLocationCoordinate2D)c: (NSString *)title: (NSString *)subtitle {
if ((self = [super init])) {
coordinate= c ;
self.title_ = [NSString stringWithFormat:#"%#", title];
self.subtitle_ = [NSString stringWithFormat:#"%#", subtitle];
NSLog(#"title_%#", self.title_);
NSLog(#"subtitle_%#", self.subtitle_);
//self.title_ = #"Title";
//self.subtitle_ = #"Subtitle";
}
return self;
}
- (NSString *)title {
return self.title_;
}
- (NSString *)subtitle {
return self.subtitle_;
}
#end
