MKMapView with custom MKAnnotation

Question

I have MKMapView. I want to put the usual MKAnnotation on my card.

These are several restaurants. How can i do this?

My question is, how can I do regular MKAnnotation?

Thanks guys.

Answer 1

If you want to fully customize the Annotation View leader. See this link .. http://blog.asolutions.com/2010/09/building-custom-map-annotation-callouts-part-1/

Answer 2

First, define a custom, not just a title and subtitles. We want to resize MKAnnotation and include some custom graphics.

There are two parts to the annotation you can customize:

• MKaNnotation
• MKAnnotationView

MKAnnotation , . MKMapView, addAnnotation: in viewDidLoad, .

MKAnnotation

@interface CPAnnotation : NSObject <MKAnnotation> {
@private
    CLLocationCoordinate2D _coordinate;
    NSString *_title;
    NSString *_subtitle;
}

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

- (id)initWithCoordinate:(CLLocationCoordinate2D)coordinate;
@end

MKAnnotation

@implementation CPAnnotation
@synthesize coordinate = _coordinate;
@synthesize title = _title;
@synthesize subtitle = _subtitle;

- (id)initWithCoordinate:(CLLocationCoordinate2D)coordinate {
    self = [super init];

    if (self != nil) {
        self.coordinate = coordinate;
    }

    return self;
}

- (NSString *)title {
    return _title;
}

- (NSString *)subtitle {
    return _subtitle;
}
@end

. MKAnnotationView. Apple, . , , . . leftCalloutAccessoryView rightCalloutAccessoryView. MKMapViewDelegate MKMapView, viewForAnnotation:.

MKAnnotationView MKMapViewDelegate

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
static NSString *const kAnnotationReuseIdentifier = @"CPAnnotationView";

MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:kAnnotationReuseIdentifier];
if (annotationView == nil) {
    annotationView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:kAnnotationReuseIdentifier] autorelease];
    annotationView.enabled = YES;
    annotationView.canShowCallout = YES;
    annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeInfoLight];
}

return annotationView;
}
