CALayerInvalidGeometry'CALayerInvalidGeometry'

Question

I'm making a tabbed view application and using CloudMade's API. I have a working project in a single view application which I try to copy to the tabbed view one.

I copied and pasted everything, set up the project preferences and everything. The tabbed view FirstViewController is exactly the same as the older single view app. How ever when I run the app, I get this error:

Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer bounds contains NaN: [inf inf; nan nan]'

I tried to google but nothing came up. It's my first tabbed view app so I'm not sure if there are stuff I need to pay attention to. I'm not even sure what code section or error report to paste here. Any help would be appreciated! Thanks alot!

EDIT 2: Here's the exception stack trace (I think):

EDIT Hi, As it seems, the tabbed view controller has nothing to do with it. I copied it again for a new single view application, and it doesn't work again. I should probably mention (didn't think it made any difference before) that the working app does NOT use storyboard, just a single xib file. the 2 not working (tabbed and single view) DOES I don't even know where to start.. Thanks

Answer 1

The problem was that I didn't link the map outlet, mapView, to the RMMapView object in the storyboard. Now it is working.

Answer 2

In your -[ParkerAssistantFirstViewController viewDidLoad] method, you send the recalculateGeometry message to an instance of RMPath. RMPath then sets the bounds of a CALayer.

Looking at the exception message, we can see that RMPath is setting the bounds of the layer to the rectangle [inf inf; nan nan]. The word inf is short for “infinity”, so your rectangle's origin is at infinity. The word nan means “not-a-number”, so your rectangle's size is completely invalid. That is what CALayer is complaining about.

Looking at the variables in your first edit, I see that scale is 0. That is suspicious. If that is the zoom factor of the view, then it's probably not valid. If that is something you control, try setting it to 1 (or some other small positive number).

Answer 3

Have you linked the QuartzCore.framework? I'm pretty sure CALayer requires the QuartzCore. You can do this by selecting your Target --> Build Phases Tab -- Link Binary with Libraries. click the plus sign, and scroll down to the bottom and select QuartzCore to link it to your project.
