Xcode6 IOS8 mapkit pins not showing - xcode6

Question

i wondering if someone may be able to help me. I am new to xcode and im trying to build a basic app. i have followed this tutorial
http://rshankar.com/how-to-add-annotation-to-mapview-in-ios/
i have copied the source code directly, i don't get any errors or warnings, however when running the app the pin locations do not show. Im not sure if they are there ( just invisible ) or whether they are not showing at all. I can't seem to find the issue.
Would anyone be able to suggest what the problem could be?
Thanks in advance.

Answer 1

actually managed to fix this, turns out the coordinates were round the wrong way!!!! Noob error!! I would like to change the callout on the pins if anyone could shed some light on where to change the code on the tutorial.
Thanks

Answer 2

To change the callout of the pins:
make the class that has your map view implement the <MKMapViewDelegate> protocol
set the delegate of your map view to that class (e.g. mapView.delegate = self;)
implement MKMapViewDelegate's (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation method in that class
something like this:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
// If it's the user location, just return nil
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
// Handle custom annotations
if ([annotation isKindOfClass:[NAME_OF_CLASS_IMPLEMENTING_MKANNOTATION_PROTOCOL class]])
{
// Try to dequeue an existing annotation view first
MKAnnotationView *annotationView = (MKAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:#"AnnotationViewIdentifier"];
if (!annotationView)
{
// If an existing pin view was not available, create one
annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"AnnotationViewIdentifier"];
annotationView.canShowCallout = YES;
// set callout
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annotationView.rightCalloutAccessoryView = rightButton;
}
else
{
annotationView.annotation = annotation;
}
return annotationView;
}
return nil;
}
On your map pins (which should be made from a class that implements the MKAnnotation protocol), you should be able to set the title and subtitle properties.
