Couldn’t have done it better myself. Excellent, thanks for posting! Hope you have more MapKit notes planned.

Comment on iPhone Note #14: Drawing a Point, Line, Polygon on top of MKMapview by Ross Kimes

Ross Kimes — Thu, 21 Jan 2010 05:08:50 +0000

Sorry for taking so long to respond. I did not realize that you had replied. Need to check back more often.

I was able to get polygons to stay on the map while panning and zooming by intercepting the touch at the UIWindow level and using a NSNotification to send out a message to update.

The problem that I am having now has to do with performance while updating. For my application, I am displaying weather warning boxes over the map, so at any given time I can have 30 or 40 of these on the map.

When drawRect: is called for each warning for every touch then it has to continuously draw each warning over and over again.

My idea to fix this is to draw out the warning box in the internal views init method and just use drawRect: to adjust the size of the box. I have tried this a few different ways, but anytime I change it I cannot get the warnings to display. Any ideas?

Thanks,
Ross

@Daniel Wood: What MKProtocol? Are you referreing to MKAnnotation Protocol? You might be missing a MapKit frameworks reference…

I’m trying to implement this method for a project I’m working. I have a question though. The GeometryAnnotation says it adopts the MKProtocol however it doesn’t use any of the methods. When I do this Xcode complains when I build, however in your sample this is not the case. Why is that?

>Is there a way to keep the polygon on the screen when scrolling and have it pan and zoom with the map? I have seen some apps do that with Google maps, but I don’t see how they did it. Any ideas?

@Ross Kimes: IT IS POSSIBLE IF they are USING GoogleMaps Javascript API. You can overlay polygons, polylines on the map. However, in my tutorial, I am trying not to call any javascript and implemented using ObjC by drawing a geometry on top of the UIViews..

Didn’t know someone was posting comments. i have enabled comments to show on the sidebar now.. hmm maybe an email alert will be good.

@justin: i have no quick answer for you mate..
1. is it only one touchView or multiple touchViews? i would guess multiple touchViews..
2. for each touchView created. Can you implement different colors for each stroke and fill. so we can see how the polygons will be drawn on top of each other.. Make sure that the path get closed and filled for a polygon…

	CGContextClosePath(context);
 
	CGContextDrawPath(context, kCGPathFillStroke);

3. Are you still drawing the points as vertexes of the polygons on top of mapview. If yes, note that viewForAnnotation gets called.

This is interesting.. I will be happy to have a wack at it if time permits..

Regards,
Rupert

Hey, I\’ve been trying to modify your code to allow multiple polygons to be added simultaneously. I\’m having a problem when drawRect is called however.

I keep an array of all of the custom views for each array so every time regionChanged I will loop through every custom view and let it know it must drawRect. The problem is, the fill disappears on the polygons. Only the most recently drawn polygon retains its fill, all of the previous ones disappear. Any insight or tips? Could there be a problem with multiple internal views layering on each other? (or does clearColor take care of that)

Thanks

Hi Stan,

Sorry for the delayed response. I just got back to Australia from Beijing just recently. Anyway, I have uploaded the source code above. Please let me know if it works for you.

Hi Rupert,
I m very new with Iphone application. I’ve just got a book from Apress.
Also, I need to create a simple application using 3 textboxes that need to launch a DatePicker like yours (as a modal view).
I tried your code but I think my knowledges are too limited.
Is it possible for you to send me your code (as a project) ?
I thank you in advance.
Stan
