How to add annotation in Mapview with image and label in IPhone?

Question

I am using MKMapview in my i

Answer 1

You can use custom view for each annotation with one UIView, one UIImageView and one Label to display different value. This will be done within the method - (MKAnnotationView *)mapView:(MKMapView *)newMapView viewForAnnotation:(id )newAnnotation. You have to take UIView double in size with transparent color with respect to UIImageView to make more precise view on zoom in and zoom out in mapview.

Code-----

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation
{
    static NSString * const kPinAnnotationIdentifier = @"PinIdentifier";
    if(annotation == self._mapView.userLocation)
    {
        return nil;
    }

    MyAnnotation *myAnnotation  = (MyAnnotation *)annotation;
    MKAnnotationView *newAnnotation = (MKAnnotationView*)[self._mapView dequeueReusableAnnotationViewWithIdentifier:kPinAnnotationIdentifier];

    if(!newAnnotation){
        newAnnotation = [[MKAnnotationView alloc] initWithAnnotation:myAnnotation reuseIdentifier:@"userloc"];
    }

    NSDictionary *dict=[alertInfoArray objectAtIndex:myAnnotation.ann_tag];
    UIView *anView=[[UIView alloc] init];
    anView.backgroundColor=[UIColor clearColor];

    UIImageView *bgImg=[[UIImageView alloc] init];
    bgImg.image=[UIImage imageNamed:@""];
    bgImg.backgroundColor=[UIColor clearColor];

    UIImageView *imgView=[[UIImageView alloc] init];
    imgView.tag=myAnnotation.ann_tag;

    UILabel *lblName=[[UILabel alloc] init];
    lblName.font=[UIFont systemFontOfSize:12];
    lblName.textAlignment=UITextAlignmentCenter;
    lblName.textColor=[UIColor whiteColor];
    lblName.backgroundColor=[UIColor clearColor];
    lblName.text=TEXT YOU WANT ;

    newAnnotation.frame=CGRectMake(0, 0, 70, 212);
    anView.frame=CGRectMake(0, 0, 70, 212);
    bgImg.frame=CGRectMake(0, 0, 70, 106);
    bgImg.image=[UIImage imageNamed:@"thumb-needhelp.png"];

    imgView.frame=CGRectMake(8,25,55,48);
    imgView.image=[UIImage imageNamed:@"girl-default.png"];
    lblName.frame=CGRectMake(5,79,60,10);



    [anView addSubview:bgImg];
    [bgImg release];
    [anView addSubview:imgView];
    [imgView release];
    [newAnnotation addSubview:anView];
    [anView release];

    newAnnotation.canShowCallout=YES;
    [newAnnotation setEnabled:YES];

    return newAnnotation;
}

Hope this helps.
