thanks

First, thank you very much for your very complete tutorial! I truly think it is the best around with the widest use of Mapkit.

Could someone tell me how it would possible to list in the tableView the annotations in order of distance to the distance location?

I thank you in advance for your help,

Cheers

I am having a problem, however, in that everything seems to be working properly with the exception that I am still seeing red pins instead of my custom annotation view. No errors, compiles and runs perfectly.

In the code snippet below, “It’s a bank” is being written to the log so this code is being called and the conditional is correctly identifying the fact that the annotation being added is of type MyAppAnnotationTypeBank. I also changed the tutorial’s clearColor to redColor in case the problem was with the image but I see no red background color.

Any suggestions would be greatly appreciated!!

Thanks!

——————————-

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

MyAppAnnotation *myAnnotation = (MyAppAnnotation*)annotation;

if([myAnnotation annotationType] == MyAppAnnotationTypeBank) {
NSLog(@”It’s a bank”);
self = [super initWithAnnotation:myAnnotation reuseIdentifier:reuseIdentifier];
self.frame = CGRectMake(0, 0, kHeight, kWidth);
self.backgroundColor = [UIColor redColor];

imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bank.png"]];
imageView.frame = CGRectMake(kBorder, kBorder, kWidth – 2 * kBorder, kHeight – 2 * kBorder);
[self addSubview:imageView];
} …

thanks a lot for this tutorial, I’ve one problem though, in the MKMapView I can only see an empty grid, without any map displayed on it…

Any idea of what’s going on ?

I’m getting the same “Terminating app due to uncaught exception ‘NSInvalidArgumentException’…” error. I’m wondering if you ever managed to figure out the problem?

Cheers,

if (annotation != mapView.userLocation)
WARNING: LOCAL DELARATION OF ‘MAPVIEW’ HIDES INSTANCE VARIABLE
{
//the rest of the ViewForAnnotation code goes here
iCodeBlogAnnotation* myAnnotation = (iCodeBlogAnnotation *)annotation;
if(myAnnotation.annotationType == iCodeBlogAnnotationTypeApple)
{
NSString* identifier = @”Apple”;
iCodeBlogAnnotationView *newAnnotationView = (iCodeBlogAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
………… rest of old code………
}

[annotationView setEnabled:YES];
[annotationView setCanShowCallout:YES];
}else{
CLLocation *location = [[CLLocation alloc]
initWithLatitude:annotation.coordinate.latitude
longitude:annotation.coordinate.longitude];
[self setCurrentLocation:location];
}

return annotationView;
}
It would be great if you could put all the mods here mentioned back into the source code. We would really appreciate it, and make a more complete tutorial, as the code isn’t working right, and hard to learn when it isn’t quite all there. Thanks guys… love the site!

I want to make a small random number generator app and wanted to know if there is a way to initiate an IBAction implicitly during the launch of the application.

Thanks,

I think you need to set your annotation in this delegate’s function, like:

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

MKAnnotationView *annView = [mapView dequeueReusableAnnotationViewWithIdentifier:@"current loc"];
annView=[[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@”current loc”]autorelease];

//this set your annotation to be tappable
annView.canShowCallout = YES;

//set the blue button on the right of the annotation
annView.rightCalloutAccessoryView=[UIButton buttonWithType:UIButtonTypeDetailDisclosure];

}
//sorry for my bad english!!
Bye!

This tutorial is very nice and saved my a lot.

i need to do like when i press on AnnotationView and it should goes to detailed view of that result.

I got method – (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control.

but i dont know that what to do in that method. If anyone has done this then pls drop some code here.

Thanks so much.

I always default to copy, so far no problems, just wondering what the rule of thumb is.

thanks

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation
{
	if ([annotation isKindOfClass:MKUserLocation.class]) return nil;
        //rest of code
}

Thanks for sharing your work. Great tutorial!!

When I build the source code, the app opened as shown below. At the background I could see only a graph kind of pattern with pins(figures) and no map.

How do I get it right?

Any help on this would be highly appreciated.

Thanks in advance.

Thanks again! Watch out for the app – “Access My Library” coming soon! Allows you the ability to access all kinds of free material from your local library via your iphone/ipod touch.

please help

step one: add the CoreLocation framework to the project.

Step two: add this function to the iCodeMapViewController.m:


- (void)setCurrentLocation:(CLLocation *)location {
MKCoordinateRegion region = {{0.0f, 0.0f}, {0.0f, 0.0f}};
region.center = location.coordinate;
region.span.longitudeDelta = 0.15f;
region.span.latitudeDelta = 0.15f;
[self.mapView setRegion:region animated:YES];
}


step three: add this code to the ViewForAnnotation Method:


if (annotation != mapView.userLocation) {
//the rest of the ViewForAnnotation code goes here
}else{
CLLocation *location = [[CLLocation alloc]
initWithLatitude:annotation.coordinate.latitude
longitude:annotation.coordinate.longitude];
[self setCurrentLocation:location];
}


you can change the setCurrentLocation method however you want, right now it is set to zoom in on the current location, which doesn’t seem all that helpful for this particular tutorial… but that should do it! hope it works for you!

everything works ok, except now we don’t get the custom annotation feature. How can we have our cake & eat it too?
