Answer 1

You can use viewForAnnotation delegate method for creating custom annotation.

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation

See the below tutorials

http://www.codigator.com/tutorials/advanced-mapkit-tutorial-for-ios-custom-callout/

http://ios-funda.blogspot.in/2012/08/custom-annotations-example.html

EDIT

You need to set the delegate in viewDidLoad

self.myMapView.delegate = self

Now in .h

@interface TrucksViewController : UIViewController

Then implement the delegate method

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation  {

    if ([annotation isKindOfClass:[MKUserLocation class]]) {
        return nil;
    }

    static NSString *defaultPinId = @"Pin";
    CustomAnnotation *pinView = (CustomAnnotation *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinId];


    if (pinView == nil) {

        pinView = [[CustomAnnotation alloc]initWithAnnotation:annotation reuseIdentifier:defaultPinId];
        //pinView.pinColor = MKPinAnnotationColorRed;
        //pinView.animatesDrop = YES;
        pinView.canShowCallout = YES;
        //NSLog(@"%f",[annotation coordinate].latitude);

    }
    else    {
        pinView.annotation = annotation;
    }


    UIButton *btn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    btn.frame = CGRectMake(275, 27, 30, 30);

    //Adding a navigation inside a callout view
    btn.tag = [sid intValue];
    //NSLog(@"%i",btn.tag);
    [btn addTarget:self action:@selector(YOUR_SELECTOR) forControlEvents:UIControlEventTouchUpInside];
    pinView.rightCalloutAccessoryView = btn;

    return pinView;

}

in CustomAnnotation.m add the below methods

-(id)initWithAnnotation:(id)annotation reuseIdentifier:(NSString *)reuseIdentifier    {

    self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];
    if (self != nil) {
        CGRect frame = self.frame;
        frame.size = CGSizeMake(46.0, 49.0);
        self.frame = frame;
        self.backgroundColor = [UIColor clearColor];
        self.centerOffset = CGPointMake(-5, -5);
    }
    return self;
}


// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
    // Drawing code
    [[UIImage imageNamed:@"locatorico"] drawInRect:rect];

}
