Comment on Using MKAnnotation, MKPinAnnotationView and creating a custom MKAnnotationView in an MKMapView by Bones

Great Tutorial, I learned a lot. I did find an issue with the custom pin. The pin drops on a location, but the pin needle is not the spot that gets converted to Long/Lat. If the user drops the pin, the long lat is off by the size of the Pin.png. The Pin head is what converted to long lat.

Also, I was curious as to why you choose to use Notification when you could have past a mapView reference to update the pin location?

Like I said, great tutorial – just some questions and observations.

Cheers

I’m completely new to this topic and here’s my question: How do you download a route from google earth or google maps with longitudes and latitudes? – Is there a tool for that?

I am creating a line between two points on a map. The line is displayed but the problem is that whenever I am zooming the map , the app crashes. This happens in 8 GB iPhone and not on 16 GB. Is it a memory issue or what?

I am submitting a snippet of code along with.
Please help me.

drawImage.frame = [tileContainerView frame];
drawImage.tag = 555;
UIGraphicsBeginImageContext(tileContainerView.frame.size);
CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound);
//CGContextSetLineWidth(UIGraphicsGetCurrentContext(), 3.0);
//CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(), 1.0, 0.0, 0.0, 1.0);
CGContextBeginPath(UIGraphicsGetCurrentContext());
CGContextMoveToPoint(UIGraphicsGetCurrentContext(), mapXFrom,mapYFrom+22);
CGContextAddLineToPoint(UIGraphicsGetCurrentContext(),(mapXFrom +mapXTo)/2,(mapYFrom+ mapYTo+22)/2);
CGContextStrokePath(UIGraphicsGetCurrentContext());
CGContextFlush(UIGraphicsGetCurrentContext());

drawImage.image = UIGraphicsGetImageFromCurrentImageContext();
[self addSubview:drawImage];
[self setUserInteractionEnabled:TRUE];
UIGraphicsEndImageContext();

Marcin,

The points I used in this demo were obtained by using the core location manager. You could do something similar and then generate your list of points from the incoming data from the core location manager.

That’s very cool solutions but in real life app, how would you get the route location points between start and destination?

You might want to have a look at http://github.com/mobilemelting/nvpolyline
This solution is especially targeted at iPhone OS versions prior to v.4.0

Although it can also be used in v.4.0
Hope this helps.
